Neurovascular structures at risk during anterolateral and medial arthroscopic...Omar Méndez Aguirre
This study describes the safety areas of 5 lateral and 3 medial hip arthroscopy portals in relation to nearby neurovascular structures based on cadaver dissections. For the lateral portals, the anterior portal had the highest risk of injuring the femoral cutaneous nerve located 1.42 cm away on average. The medial portal with the narrowest safety margin was the anterior medial portal, located an average of 2.14 cm from the femoral artery laterally and 0.87 cm from the obturator nerve inferiorly, posing risks of injuring these structures. While the lateral portals generally had wider safety margins, the anterior portal specifically had the closest relationship to a neurovascular structure and therefore the highest risk of injury.
The value of clinical knowledge in understanding pathological findings in Ang...University of Derby
Palaeopathology is about understanding what you are looking at and how it relates to actual clinical conditions. It is often only by having an awareness of the clinical condition that you can come to a diagnosis when viewing osteological features.
Using examples from clinical photography, specifically orthopaedics, examples of pathology from the Anglo-Saxon cemetery in Little Chester, Derby and papers published, in many and varied journals, by Calvin Wells it is possible to see the importance of viewing palaeopathology from a clinician’s perspective.
Population level analysis, for example the quantification of osteoarthritis (OA) in a particular area or cemetery, gives information about the frequency of occurrence of specific traits associated with OA. What it doesn’t do is give us a picture of actual diagnoses. Under a general category of OA of the knee you could have individuals with varus or valgus deformities, eburnation of the tibial plateau and femoral condyles and accompanying osteophytes through to variations in the patella-femoral joint e.g. subluxation, lateral patella maltracking and patella alta.
Individual diagnoses though leading to short simple papers or a series of case studies can be equally valuable in understanding how our ancestors lived. Through looking at actual diagnoses we can link how people lived with specific increases or decreases in clinical conditions that could lead to ways of decreasing the impact of OA in modern populations.

Introduction: Partial or complete aplasia of the posterior arches of the atlas is a well-documented anomaly but a relatively rare condition caused by a defect in their closure. This condition is usually asymptomatic so most are diagnosed incidentally.
Case report: We report the case of a patient who presents a defect of the posterior arch of atlas.
Conclusion: There is a variety of the congenital defects of the arch of the atlas. Further studies are required on these lesions in order to take possible protection measures against trauma, and the selection between conservative or surgical treatment.
A Large Intra-Articular Ossicle in the Knee Joint-A Rare Occurrence_Crimson P...CrimsonPublishersAICS
This document presents a case report of a rare occurrence of a large intra-articular ossicle in the knee joint of a 14-year-old male. Magnetic resonance imaging found a large ossicle impinging on the anterior cruciate ligament, causing lifting of the ligament anteriorly and laterally. Intra-articular ossicles in the knee are uncommon but can grow to a significant size, as seen in this case, producing mass effect and clinically mimicking an ACL injury. The etiology of intra-articular ossicles is unclear but may be congenital, traumatic, or degenerative in origin.

1) The study compared the body mass index (BMI) of elderly patients aged 65+ who were hospitalized with fractures of the proximal femur from falls, to elderly patients without fractures.
2) It found that patients with fractures were significantly taller and had a significantly lower average BMI (22.6) than those without fractures (average BMI of 25.5).
3) Among fracture patients, 12% had low weight, 62.7% normal weight, 24% overweight, and 1.3% obese, while among non-fracture patients the percentages were 5.6%, 43.8%, 33.7%, and 9.8% respectively.
The Incidence of Traumatic Posterior and Combined Labral Tears in Patients Un...Lennard Funk
Posterior and combined labral tears are more common than previously thought, especially in young active populations. The study reviewed 442 patients undergoing shoulder stabilization surgery and found that posterior and combined tears accounted for 47% of cases, compared to only 53% being isolated anterior tears. Rates of posterior and combined tears were even higher in sporting populations (52%) compared to non-sporting populations (32%). Rugby players in particular had a high rate of posterior and combined tears (53%). The study concludes that posterior and combined shoulder instability is more prevalent than reported, especially in contact sports.

This study investigated risk factors associated with primary knee osteoarthritis in 174 Middle Eastern patients. The mean age was 59.9 years and most patients were female. Obesity, with a BMI over 24, was present in 96.5% of cases. Lower back pain in the previous year was reported by 49.4% of patients. A strong association was found between BMI and knee osteoarthritis. Gender was also found to be a risk factor, with knee osteoarthritis being more prevalent in females.
This study evaluated the intermediate and long-term results of femoral neck lengthening (Morscher osteotomy) in 18 patients (20 hips) with a median follow-up of 7 years. Postoperatively, the Trendelenburg test was negative in most patients and the median Harris Hip Score improved significantly. Radiographic examination found progression of osteoarthritis in 3 patients, while one operation failed and required total hip replacement after 4 years and two others required it at 10 years. The procedure successfully reduced leg length discrepancy in most patients. The study concluded that Morscher osteotomy can effectively treat patients with short femoral neck and overgrown greater trochanter with a positive Trendelenburg test and mild leg length
This document discusses a 48-year-old woman presenting with neck pain and right upper extremity symptoms two years following an anterior cervical discectomy and fusion (ACDF) at C4-C7. Imaging shows a nonunion at C6-C7 with graft collapse and anteriorly migrated screws. The patient's options for revision surgery are discussed, including an anterior-only, posterior-only, or combined anterior-posterior procedure. Risk factors for ACDF nonunion and strategies for bone grafting and fixation are also reviewed.
In this study of 277 post-menopausal women, the researchers found:
1) Higher bone mineral density was associated with increased severity of disc space narrowing at both the lumbar spine and femoral sites.
2) There was no association found between bone mineral density and severity of osteophytes.
3) Biochemical markers of bone resorption (CTX levels) decreased with increased severity of disc space narrowing, but were not associated with osteophyte severity. This suggests disc space narrowing may have a protective effect against bone loss through decreased bone resorption.
This study aimed to establish normative measurements of cervical spinal canal and spinal cord dimensions based on MRI scans of 140 healthy volunteers. The researchers found that dimensions varied significantly based on sex, spinal level, height, and to a lesser extent age. They defined normal ranges for sagittal diameters and cross-sectional areas of the spinal canal and cord at C1, C3, and C6 levels, accounting for sex, level, age and height. Having defined normal cervical spinal anatomy will aid radiologists in assessing potential spinal stenosis.

This study investigated factors associated with the onset of generalized osteoarthritis (OA) in older women through qualitative interviews. It found that hereditary factors were present in most participants. Participants also believed that depression, stress, diet, and low health status during vulnerable periods like World War II contributed to their OA. The findings generate hypotheses for future quantitative studies to test.
This study examined the association between estrogen receptor alpha (ERα) gene haplotypes and radiographic osteoarthritis (OA) of the knee in 1,483 elderly men and women. Three haplotypes (px, PX, Px) were identified. Carriage of the PX haplotype was associated with an increased prevalence and severity of radiographic knee OA, with odds ratios of 1.3 for heterozygotes and 2.2 for homozygotes. Separate analyses showed the association was driven by osteophytosis. This study provides evidence that polymorphisms in the ERα gene are risk factors for radiographic knee OA in both men and women.
This study examined the relationship between hormone replacement therapy (HRT) use and osteoarthritis (OA) in women. The study analyzed radiographic data from 1003 women and found that current HRT users had a 3-fold lower risk of knee OA compared to never users. Current HRT use was also associated with a non-significant reduced risk of distal interphalangeal OA. No clear protective effect was seen for carpometacarpal OA. Past HRT use showed weaker or no protective effects. The results suggest HRT may have a protective effect against OA when used continuously but not after stopping use. Larger prospective studies are still needed to confirm these findings.
This study measured patellar tendon length in 42 knees with a history of patellar dislocation and 51 control knees using lateral X-rays and MRI images. The mean patellar tendon length was significantly longer in the dislocation group compared to controls, both on X-ray (53mm vs 46mm) and MRI (52mm vs 44mm). Measuring the distance from the tibial plateau to the tibial tuberosity insertion point found no significant difference between groups, indicating patella alta is caused by a long patellar tendon rather than a low insertion point. A tendon length over 50mm measured on MRI was found to be a sensitive and specific indicator of patellar instability.
Duchenne muscular dystrophy is an X-linked recessive genetic disorder. For a mother who is a carrier and a father who does not have the gene, the chance that their son will have Duchenne muscular dystrophy is 25%.
Spine Arthroplasty or Artificial Disc Replacement is a new term which is used more and more in international scientific meetings and publications starts to dominate the scenery. The last three decades have been the most revolutionary in the history of spine treatment. The 80’s were dominated by the development of modern implants for internal segmental fixation such as pedicle screw systems and others. In the 90’s „Mini-open“ as well as „closed“ endoscopic techniques replaced the majority of conventional surgical approaches . Progress in biological and biochemical research seems to open new perspectives in fusion technology. We must not forget that bony fusion of a functional spinal unit is non physiological and it is associated with a variety of proven and (yet) unproven undesired effects and sequelae. At the beginning of this century, the progress in implant technology open a new dimension for spinal reconstructive non-fusion surgery. A variety of new implants are used today for: nucleus pulposus, total disc replacement, dynamic posterior reconstruction systems, posterior shock absorbers and injectable intradiscal materials. Cervical Disc Replacement is a Motion preserving surgery, Treat painful / pathologic process while restoring/maintaining motion, Decreased stress in adjacent levels, May prevent problems of adjacent segment disease, secondary surgery, pseudoarthrosis.
Comparing arthroplasty (ACDR) vs fusion (ACDF) most of the studies are in favour of (ACDR) because of, Higher neurologic success, Earlier return to work, Degrees of maintained motion, Adjacent Segment Degeneration 5 yrs, Statistically significant better scores (NDI, Arm pain, VAS, and SF-36 scores), lower revision rate (Reoperation rate for ACDF – 11.3% vs 2.9% ACDR)

1) The document discusses a study of 75 multiple myeloma patients who underwent surgical treatment for skeletal complications between 1980-2005.
2) The study found that survival after surgery was favorable, with 37% surviving at 5 years and a median survival of 4.7 years.
3) Factors associated with better survival included having a single bone lesion, negative bone marrow biopsy, no paraproteinemia, and lower Salmon-Durie stage (a staging system for multiple myeloma).
The document summarizes a journal club discussion on autologous chondrocyte implantation (ACI) for treating articular cartilage defects in the knee. It provides details on the ACI procedure, which involves harvesting cartilage cells from a patient's knee, growing them in culture, and implanting them back into the defect using a periosteal patch or collagen membrane. The document compares ACI to other cartilage repair techniques like microfracture and drilling, finding ACI can regenerate hyaline-like cartilage while other techniques only produce fibrocartilage with limited lifespan. Rehabilitation guidelines and long-term assessment of ACI grafts via MRI, biopsy and arthroscopy are also summarized.
—Kyphosis and lordosis changes might be related to back extensor weakness and osteoporosis. The purpose of this study was to find out the correlations between thoracic kyphosis, lumbar lordosis with back extensor strength (BES) and bone mineral density (BMD). Methods: Thoracic kyphosis, lumbar lordosis, maximal isometric strength of the back extensors and BMD of the lumbar vertebral were evaluated in 47 elderly (50-75 years old)women. BMD of the lumbar vertebral was measured using Dual-Energy X-Ray Absorptiometry (DEXA) and kyphosis and lordosis degree were assayed using a flexible ruler. The maximal isometric strength of the back extensors was measured using an isometric manual muscle tester (MMT). Data were analyzed using ANOVA and independent t-test at p≤0.05 level of acceptance. Results: A significant reverse correlation was shown between BES and kyphosis (p=0.044, r=-0.30). No significant correlation were found between BES and lordosis degree, nor between lumbar vertebral BMD and, both, kyphosis and lordosis degrees. However, there was a significant difference in BES between three groups with various degree of kyphosis (p≤ 0.05). Conclusion: It can be concluded that the severity of thoracic kyphosis may be influenced by BES. So, stronger back extensor can prevent thoracic kyphosis despite decreased BMD.

Spondylisthesis by dr venkata rama krishnaiah vapms copvrkv2007
Spondylolisthesis is the slippage of one vertebra over another. It is classified into six types based on cause, including dysplastic (congenital), isthmic, degenerative, traumatic, pathological, and iatrogenic. Isthmic spondylolisthesis is most common, typically occurring at L5-S1, and is often caused by a stress fracture of the pars interarticularis. Diagnosis involves x-rays and sometimes CT or MRI. Treatment includes rest, medications, bracing, physical therapy, and sometimes surgery to stabilize and fuse the vertebrae. Physical therapy focuses on core strengthening, stretching, and exercises to improve mobility and reduce pain.
Biological profiling from skeleton remains.PAñķåj JáņGřã
This document discusses biological profiling techniques used in forensic anthropology to analyze skeletal remains. It covers estimating age, sex, stature, ancestry, and cause and manner of death from bones. Age can be estimated from dental development in subadults or degenerative changes in adults. Sex is estimated by examining pelvic and skull morphology. Stature uses long bone measurements in regression equations. Ancestry examines cranial features. A case study example analyzes remains from New York to estimate age over 40 years old.
Osteochondritis dissecans (OCD) is a condition where pieces of bone or cartilage break off near a joint. It most commonly affects the knees, elbows, and ankles of young, active individuals. The cause is likely multi-factorial, involving vascular, genetic, biomechanical, and endochondral ossification factors that create a vulnerable area in the bone or cartilage. Diagnosis involves examining the patient's history and symptoms and may include imaging tests like x-rays or MRI. Treatment depends on the maturity of the bones and stability of the lesion.

Diagnosis involves examining the patient's history and symptoms and may include imaging tests like x-rays or MRI. Treatment depends on the maturity of the bones and stability of the lesion.
Osteoscopic assessment of sexual dimorphism in hip bone.acta medica internati...Sanjeev kumar Jain
This study visually assessed sexual dimorphism in 46 hip bones from known-sex individuals using five non-metric traits: (1) preauricular surface, (2) greater sciatic notch, (3) composite arch, (4) inferior pelvis, and (5) ischiopubic proportions. Traits in group 1 were most sexually dimorphic while traits in group 5 were least dimorphic. Visual assessment of complete hip bones can accurately determine sex, though some difficulties may arise with fragmentary remains. Hip bone features are fairly stable for sex determination across populations.
This study investigated age and gender differences in three mandibular parameters (gonial angle, ramus height, and bigonial width) using digital panoramic radiographs of 209 dentate Jordanian subjects. The results showed that males had slightly higher measurements than females for all three parameters. Gonial angle and bigonial width increased with age while ramus height first increased from ages 11-29 and then decreased with increasing age. Statistically significant differences were found between several age groups for each parameter, suggesting the mandible undergoes remodeling changes with aging.
This study investigated age and gender differences in three mandibular parameters (gonial angle, ramus height, and bigonial width) using digital panoramic radiographs of 209 dentate Jordanian subjects. The study found that gonial angles and bigonial widths increased with age while ramus height first increased from ages 11-29 and then decreased with age. Males generally had higher parameter values than females. Statistically significant differences were seen between various age groups for the three parameters. The study supported that mandibular morphology is influenced by both biomechanical forces and biochemical alterations with aging.
Analytical Study of Clinicopathological Data of Saudi Patients with Osteoarth...Prof. Hesham N. Mustafa
SUMMARY: Knee osteoarthritis (OA) is a common disabling disease. Epidemiological studies have revealed various risk
factors for OA, including sex, aging, obesity, occupational illnesses, and chronic diseases. Here we evaluate the clinical, pathological,
and radiological findings of knee OA in a subset of Saudi patients who were subjected to total knee replacement (TKA). The study
population included 30 Saudi patients with knee OA who were operated by TKA (from June 2014 to December 2015) in the Department
of Orthopedics, Faculty of Medicine, King Abdulaziz University, Saudi Arabia. Patient’s clinical and radiological data were collected
from the hospital files. Pathological examination of the excised superior articular surface of tibia and femoral condyles were done.
Pearson Chi-squared analysis was used to test for differences between the variables in associated risk factors. There were more women
than men. Sixty per cent of patients were older than 60 years [mean age, 59.2 (females) and 61.7 (men) years-old]. All patients exceeded
obesity class 1, with females being more obese than males. Pathological examination of the superior articular surface of tibia and femoral
condyles showed high score lesions, which was more apparent in females than in males. Radiological findings showed that most lesions
were high grade. The findings of this study will help to understand the pathogenesis of OA and improve treatment decision making
relevant to TKA in knee OA in Saudi Arabia and elsewhere.

This document summarizes a study on the incidence of mylohyoid bridging in mandibles from the Uttarakhand region of India. The study examined 121 mandibles (69 male, 52 female) and found mylohyoid bridging in 9 mandibles (7.43% incidence). Bilateral bridging occurred in 5 mandibles and unilateral in 4 mandibles. The bridging was classified as distal-partial, proximal-trace, or trace. No significant difference was found between males and females. The incidence in this study is similar to some previous studies on Indian populations but lower than one other study on North Indians.

The incidence was similar to other studies on North Indian populations.
ADOLESCENT IDIOPATHIC SCOLIOSIS AND ITS ORTHOTICS MANAGEMENT.pptxMritunjay Dev
Adolescent idiopathic scoliosis (AIS) is a type of scoliosis that typically develops during adolescence, between the ages of 10 and 18, and is characterized by an abnormal sideways curvature of the spine. "Idiopathic" means that the cause of the condition is unknown.
Here are some key points about adolescent idiopathic scoliosis:
Onset: AIS usually becomes noticeable during the growth spurt that occurs just before puberty. It can progress during the adolescent growth phase, but it typically stabilizes once the child reaches skeletal maturity.
Curvature: The degree of curvature can vary widely among individuals, ranging from mild to severe. Curves may occur in different regions of the spine and can be classified as thoracic (affecting the upper back), lumbar (affecting the lower back), or both.
Symptoms: In mild cases, AIS may not cause any symptoms or may only cause mild back pain or discomfort. In more severe cases, it can lead to noticeable spinal deformity, uneven shoulders or hips, and difficulty breathing if the curvature compresses the chest cavity.
Diagnosis: AIS is usually diagnosed through a physical examination, including a forward bend test
This study examined the relationship between lumbar scoliosis and osteoporosis in postmenopausal women. The researchers analyzed dual-energy x-ray absorptiometry (DXA) scans of 900 randomly selected postmenopausal women aged 64-88 years old. They measured the Cobb angle to assess lumbar scoliosis and bone mineral density at the femoral neck, total hip, and spine to assess osteoporosis. They found that both the incidence and degree of lumbar scoliosis, defined as a Cobb angle over 10 degrees, increased significantly with age. However, after adjusting for covariates like age, weight and ethnicity, there was no significant association between bone mineral density at any site and the Cobb angle.
This document reviews scoliosis, defined as a lateral curvature of the spine with torsion. It discusses classification of scoliosis types including idiopathic, neuromuscular, congenital, degenerative, and traumatic. Diagnosis is made through physical exam and x-rays, with Cobb angle measurement used to determine curve severity. Etiology may involve genetic and connective tissue factors as well as skeletal muscle and growth imbalances. Screening recommendations and Tanner staging of pubertal development are also covered.
This research article studied parameters of the lower lumbar intervertebral foramen related to the superior articular process using X-ray imaging. X-rays of the lumbar spine from 104 adults were analyzed. Measurements were taken of the height, width, and other dimensions of the lower lumbar intervertebral foramen. The results found no significant gender differences in foramen parameters. Parameters related to the superior articular process, such as height and distance from bony landmarks, showed significant age-related differences between those aged 40-60 and over 60. This data supplements the intervertebral foramen database and provides a reference for individualized minimally invasive spine surgeries, especially in elderly patients over 60 years old.
Vertebral fractures were the strongest marker of low bone mineral density (BMD), with two-thirds of women with vertebral fractures found to be osteoporotic. Half of women with hip or humerus fractures and one-third with forearm fractures were osteoporotic. Previous fractures correlated inversely with BMD, with women having vertebral or hip fractures, or multiple fractures, more likely to have lower BMD and osteoporosis. Investigation for osteoporosis is warranted for all women aged 55-75 presenting with a low-energy fracture, prioritizing those with vertebral, hip, or multiple fractures.
This document provides an overview of slipped capital femoral epiphysis (SCFE), including its definition, epidemiology, classification, presentation, imaging, treatment options, and treatment approach. SCFE is a displacement of the femoral head relative to the femoral neck via the growth plate. It most commonly presents as hip or knee pain in obese adolescent boys and girls. Imaging includes radiographs and MRI to assess the degree of slippage. Treatment depends on factors like stability and includes in situ pinning, proximal femoral osteotomy, or surgical hip dislocation. For unstable slips, urgent reduction and fixation is indicated. Mild stable slips are treated with in situ pinning while moderate to severe cases may require intertrochanteric
Skeletal maturity can be assessed using hand-wrist radiographs. Several methods exist including Greulich and Pyle (1959), Bjork (1972), and Fishman (1982). Greulich and Pyle use an atlas to compare maturity. Bjork identifies 9 stages of ossification. Fishman's Skeletal Maturation Assessment identifies 11 stages based on ossification events in the fingers, wrist, and radius. Assessment of skeletal maturity is important for orthodontic treatment planning to determine facial growth status and the timing of growth modification interventions.
The document provides instructions for a task in CINAHL regarding ankle injuries. It includes searching in CINAHL for information on physical examination, diagnosis, and manipulative therapy of the ankle joint from 2010 onwards. It also includes exporting references to Mendeley and creating a weekly alert for new information on the topic.
This review article summarizes research from the Spinal Deformity Study Group on classifying spondylolisthesis based on sagittal spinopelvic alignment. The classification defines 6 types based on grade of slip, pelvic incidence, and spino-pelvic alignment. Research found abnormal pelvic and spinal parameters in spondylolisthesis patients compared to controls. For low grade slips, some have increased pelvic tilt and lordosis ("shear" type) while others have decreased parameters ("nutcracker" type). High grade slips were found to have two alignment subgroups - a "balanced" group standing with high sacral slope and a "retroverted/unbalanced" group with low sac
1. Interspinous process spacers are implants placed between adjacent lumbar spinous processes as a less invasive alternative to spinal fusion surgery. They are designed to preserve motion while reducing pain by decreasing pressure on spinal discs and facets.
2. Biomechanical studies show that spacers reduce intradiscal pressure and facet joint contact area at implanted levels without affecting adjacent segments. Clinical reports also suggest spacers provide short-term symptom improvement for appropriately selected patients.
3. However, concerns exist that the spacers may cause local pain over time and weaken spinal stability by disrupting ligaments and maintaining facet joints in distraction. Further research is still needed to establish the long-term efficacy and safety of interspin

This document discusses various metabolic bone diseases including osteoporosis, rickets, osteomalacia, and others. It provides details on:
- The definition and causes of osteoporosis as well as how it leads to loss of horizontal trabecular bone.
- The differences between rickets, which affects growth plates, and osteomalacia, which affects mineralization of bone. Causes include vitamin D deficiency and other disorders.
- Features of various other metabolic bone diseases like hypophosphatasia, hyperparathyroidism, and their effects on bone structure and mineralization.
Morphohistometric study of the ligamentum flavum in cervical,thoracic and lum...Prof. Hesham N. Mustafa
ABSTRACT Anatomic characterization and fine structure of the human ligamentum flavum (LF), especially at different spinal levels, represent an attractive focus for the scientific and surgical application. Descrip-tive anatomical and structural study of LF at the cervical, thoracic and lumbar levels of the vertebral column in human cadavers is carried out here. The aim of the work is to clarify the anatomical features and fine structural differences in the human LF at different vertebral levels (cervical, thoracic and lumbar). Specimens of vertebral column were ob-tained from 34 human preserved cadavers. Their average age ranged between 56 and 69 years. Morphometric parameters including height, width and thickness of the ligament flavum at the mid-levels of cervical, thoracic and lumbar regions were measured. Sections obtained from different levels were stained with different stains. Morpho-metric measurements involved the relative elastic area, relative collagen area, elastic area% and collagen area% were measured.The results of the height, width and thickness of the LF at different spinal levels showed gradual increase in their mean values respectively. The LF midline gaps were found in the cervical, thoracic and lumbar regions. The morphometrical measure-ments showed that the average elastic area was highest in the cervical region and lowest in the tho-racic region. In the lumbar region, the percentages of both elastic area and the collagen area were nearly the same. The characterization of morpho-logical and histological aspects of the LF at differ-ent spinal levels will be of great importance for ap-plications in spinal surgery, biomechanical and physical rehabilitation of vertebral column.Keywords: Ligamentum Flavum – Spinal – Collagen and elastic fibers
Los estudios sobre joyería indígena de Patagonia han privilegiado las colecciones procedentes de Araucanía (centro-sur de Chile), considerando en menor escala la producción platera de la vertiente oriental de los Andes en el siglo diecinueve. Este artículo pre- senta los resultados obtenidos del estudio de los aros de plata reunidos en 1896 por Henry de La Vaulx en la toldería del cacique Valentín Saygüeque (1830-1903), famoso por el tesoro monetario y platero acumulado antes de su derrota militar en 1882, cuan- do encabezaba un grupo de orígenes mixtos huilliche, pehuenche, pampa y tehuelche que controlaba el “País de las Manzanas” (provincia de Neuquén, Argentina). El análisis formal, tecnológico y físico-químico de la colección conservada en el Musée du quai Branly de Paris ofrece una primera síntesis sobre una producción platera contextualizada geográfica y cronológicamente, así como criterios analíticos para la datación de la joyería indígena.
El trabajo aborda las epistemes decoloniales como prácticas antagónicas al estado de relaciones (inter)culturales impuestos por la colonialidad. A partir de un análisis semiótico aplicado a dos obras del pensamiento mapuche, se propone la dimensión epistémico decolonial como basal en su organización de sentidos, comprendiendo que son sistemas de conocimientos en oposición a las formas de dominación que desde el mundo moderno-colonial se han ejercido en desmedro del pueblo mapuche. Se concluye proponiendo que este tipo de epistemes contribuyen a re-escribir la interculturalidad, construyendo, así, un nuevo marco de convivencia humana.
El poder en las ciudades coloniales latinoamericanas ha sido representado como “blanco” y “masculino”. Por medio de este texto nos aproximaremos a las transformaciones experimentadas en las representaciones raciales, de clase y género en la ciudad de Cuenca (Ecuador) a partir del análisis comparativo de la elección de las reinas y cholas cuencanas, en un contexto social marcado por la reivindicación del mestizaje cultural.
Presentamos los resultados de un estudio exploratorio y cualitativo acerca de las transformaciones agrarias y los conflictos hídricos que han emergido en las últimas tres décadas entre localidades históricamente agrícolas y grandes empresas mineras en el norte de Chile. Investigamos en tres casos de estudio: Quillagua (comuna María Elena, Región de Antofagasta), Peine (comuna San Pedro de Atacama, Región de Antofagasta) y Los Loros (comuna Tierra Amarilla, Región de Atacama). A partir del discurso de los entrevistados, efectuamos una reconstrucción histórica de los cambios centrándonos en tres dimensiones interrelacionadas que permiten abordar el problema: características de las actividades agropecuarias, presencia y vínculos con la minería, y situación de los recursos hídricos.
El análisis antracológico realizado en el sito de El Caño (provincia de Coclé, Panamá) nos permite hacer una primera aproximación a las posibilidades que este tipo de análisis arqueobotánico proporciona para el estudio de las sociedades de jefatura, y específi- camente de sus contextos funerarios. La identificación de los recursos leñosos utilizados, y el establecimiento de hipótesis acerca de su posible función en relación con el ritual mortuorio, es fundamental para poder profundizar en la comprensión del ritual y de la gestión de los recursos realizada por las jefaturas en el istmo de Panamá.
El presente trabajo examina variaciones dietéticas asociadas a diferencias de estatus al interior de comunidades jerarquizadas utilizando indicadores de patología oral. En los Andes Centrales, a pesar de la existencia comprobada de profundas divisiones sociales, la etnohistoria sugiere pocas diferencias dietéticas durante periodos tardíos, pero los datos bioarqueológicos que sustenten esta afirmación son escasos. Se analizaron 145 individuos exhumados del cementerio Los Pinos del valle de Huaura, costa central peruana (ca. 1200-1300 d.C.). Este conjunto de individuos fue clasificado en tres grupos de estatus social de acuerdo con la riqueza en ofrendas de los entierros. En dicha muestra se estudiaron 14 indicadores de patología oral. Los resultados muestran que todos los individuos de Los Pinos, independientemente de su grupo de estatus, estaban expuestos a una dieta considerablemente cariogénica y exhiben un patrón de lesiones común en el que predominan caries oclusales y una altísima proporción de caries cervicales (que parece estar estrechamente asociada al consumo de chicha), remanentes radiculares y abundantes pérdidas dentales en vida (con una mayor propensión en mujeres). Los datos de patología oral sugieren que el estatus social no condicionó el consumo diferenciado de carbohidratos y confirman el carácter extendido del hábito de coqueo en todos los grupos sociales, con un ligero predominio en individuos masculinos de estatus superior.
Se presenta el análisis zooarqueológico de los restos de guanacos (Lama guanicoe) recuperados de la ocupación Arcaica Tardía del sitio MAU085, emplazado en el valle de Mauro, Norte Semiárido chileno. Este análisis tuvo por objetivo entender la organización espacial del sitio, el cual corresponde a un campamento de cazadores-recolectores orientado al procesamiento de animales, entre otras actividades. El conjunto de análisis realizados apunta a una ocupación no estival y reiterada del sitio desde el 3.200 hasta los 2.500 años a.p., con una organización espacial relacionada a actividades de procesamiento, descarte y transporte principalmente de guanacos, junto a la confección y preparación de artefactos líticos de apropiación.
Presentamos los resultados de la investigación arqueológica de un sitio fechado hacia el Holoceno Medio en los Andes del Norte Semiárido de Chile. La escasez de este tipo de evidencias pone de relieve la importancia de dar cuenta cabal del contexto estudiado y los conjuntos ahí recuperados. Las características del sitio como una estación de tareas de tipo avistadero hacen que Techo Negro se integre de forma significativa al conjunto de información regional disponible y permite confrontarla con el actual estado de algunos modelos de ocupación que incluyen la distribución diferencial de sitios y los cambios ambientales a escala de milenios.
Este trabajo discute la secuencia de desarrollo histórico prehispánico en el Norte Semiárido de Chile a partir del estudio de las dinámicas espaciales y temporales de las ocupaciones humanas en la cuenca hidrográfica del río Limarí. A partir del estudio de asentamientos, materiales depositados en colecciones y arte rupestre se observa una secuencia de transformaciones y desarrollo desde el Arcaico Temprano hasta el período Incaico que diverge de lo tradicionalmente planteado para la región, reconociéndose ritmos de cambios sociales diferenciales dentro de la misma zona, especialmente en relación con la tradicional asociación entre incorporación de cerámica y la constitución de un modo de vida agrícola. La incorporación del arte rupestre permite articular sus características espaciales y representacionales con procesos más amplios, discutiéndose las relaciones establecidas entre dinámi- cas y cambios sociales con los flujos de información que producen las representaciones rupestres y sus respectivas audiencias.
En las últimas décadas los arqueólogos han tendido a examinar la problemática Tiwanaku fuera del núcleo altiplánico, principal- mente en términos de acceso a recursos y/o complementariedad ecológica y religiosa, entre un centro y su periferia. Sin embargo, dominados por las ideas de Estados o imperios, estas reconstrucciones adolecen de reduccionismo económico e iconográfico, en perjuicio del entendimiento de los fenómenos políticos andinos. Dentro de esta problemática, retomamos la relación entre Tiwanaku y San Pedro de Atacama a partir de un nuevo estudio de la cerámica negra pulida de los cementerios de Solcor y Coyo, en razón del carácter fundacional que Le Paige y Tarragó le imprimieron a esta alfarería para abordar el impacto altiplánico en la región. Este análisis, en conjunto con la reciente evidencia bioarqueológica obtenida por este equipo y otros, nos permiten repensar este vínculo y avanzar hacia la compresión de una realidad social mucho más dinámica, heterogénea y desigual.

La identificación de las comunidades a partir de la organización socioespacial de su territorio es un interés clásico, pero no menos problemático de los estudios regionales en arqueología. Dentro del contexto andino, el problema es particularmente dificultoso debido a la flexibilidad de escala demográfica e identitaria del concepto vernáculo de ayllu tal como aparece en las fuentes etno- históricas y etnográficas, así como por el hecho de la paradigmática espacialidad discontinua e interdigitada del poblamiento de los territorios descritos por las mismas fuentes.
El análisis del poblamiento prehispánico tardío (siglo XI a siglo XVI d.C.) del valle del Apurímac (Cusco, Perú) es una oportunidad para contribuir en esta discusión a partir de informaciones inéditas referentes a la estructura territorial de las comunidades aldeanas asentadas en uno de los más profundos valles interandinos ubicado al pie de la cordillera de Vilcabamba. El estudio combina análisis espacial, ecología cultural, arqueología del paisaje y analogía etnográfica para proponer una lectura multifactorial y multiescalar de los patrones de asentamiento prehispánicos. A escala local, el estudio pone en evidencia un tipo de red de asentamientos re- currente que podría corresponder al esquema socioespacial de comunidad aldeana. A escala regional, el estudio muestra, desde una perspectiva bottom-up, la heterogeneidad del poblamiento del valle, el mismo que ilustra la compleja situación geopolítica expresada por las fuentes etnohistóricas sobre este espacio territorial intermedio vecino al corazón del Tawantinsuyu. Desde el punto de vista teórico, los datos permiten desarrollar una reflexión acerca de los fundamentos territoriales de las comunidades aldeanas prehispánicas tardías.
Los estudios sobre la presencia de límites sociales o de diferentes sociedades y poblaciones en el humedal del Paraná inferior (Argentina) fueron siempre inferidos a partir de la base material del registro arqueológico, ya sea por diferencias estilísticas o bien por la presencia/ausencia de ciertas características arqueológicas materiales. El presente trabajo tiene como objetivo complementar dichos estudios mediante el análisis de rasgos epigenéticos craneofaciales. Para esto se analizaron 39 indivi- duos provenientes, por un lado, del norte y sur del Paraná Guazú y, por el otro, de los subsectores ambientales denominados Planicies inundables y Delta inferior. Los resultados obtenidos muestran diferencias estadísticamente significativas entre estas dos últimas unidades ambientales, dadas por la presencia de la foramina infraorbital múltiple y del hueso wormiano epiptérico entre los individuos de Planicies inundables y su completa ausencia entre aquellos del Delta inferior. Estos resultados, si bien preliminares, son un gran avance para la arqueología regional, ya que es la primera vez que la existencia de diferencias bio- lógicas puede ser interpretada como la coexistencia de diferentes sociedades a través de análisis que exceden la comparación intrarregional de la variabilidad artefactual.
La presente investigación explora el grado de estrés sistémico al que estaban sometidas las poblaciones de San Pedro de Atacama durante los períodos Medio e Intermedio Tardío mediante el análisis de cortisol en el cabello de restos humanos de estos períodos. Los niveles similares de cortisol encontrados en los individuos de San Pedro de Atacama y en individuos actuales sugieren que, si bien las condiciones ambientales y sociales de las poblaciones prehispánicas fueron muy distintas a las actuales, la población prehispánica en San Pedro de Atacama no estaba sometida a niveles de estrés sistémico mayores que la actual, posiblemente debido a la larga historia de ocupación en la región que permitió que dichas poblaciones se adaptaran a sus condiciones particulares. Los niveles de cortisol de los individuos analizados del período Medio mostraron una tendencia a ser menores que los del Intermedio Tardío, congruente con las diferencias en la calidad de vida sugeridos por marcadores osteológicos y con los cambios culturales y ambientales asociados a ambos períodos. Aunque diversos factores pueden afectar los niveles de cortisol encontrados en muestras arqueológicas, este marcador muestra el potencial para complementar los resultados obtenidos sobre las poblaciones de San Pedro de Atacama utilizando otros enfoques.
El artículo explora la vinculación entre las condiciones de vida que enfrentan los y las inmigrantes en la ciudad de Santiago, con las formas de habitar que ellos mismos despliegan en un espacio público específico: una esquina ubicada en el centro histórico y cívico de la ciudad de Santiago, en la que los migrantes concurren cotidianamente a buscar trabajo y compartir con los connacionales. Se sostiene que estas formas de vivir y habitar la esquina se vuelven modos de vivir el proyecto migratorio, en un contexto de sobre- vivencia cotidiana donde el trabajo alcanza máximos niveles de precarización. El encuentro, reconocimiento y apropiación de un lugar público posibilita el desarrollo de procesos identitarios que configuran un “nosotros” que se desarrolla a partir de procesos de diferenciación, los que a su vez revierten estigmatizaciones y reafirman posiciones de poder dentro de la propia comunidad de migrantes. De este modo se sostiene que la generación de identidades colectivas se construye a partir de las formas de habitar el lugar y de los procesos de distinción que se generan respecto de la población local y respecto de la propia comunidad de migrantes.
Este documento presenta los resultados de una etnografía escolar realizada en una escuela rural mapuche en la región de la Araucanía en Chile. La escuela se gestiona de manera autónoma por la comunidad mapuche local y busca implementar un modelo educativo vinculado a la identidad y cultura mapuche. Aunque la escuela se define como "no intercultural", la investigación encontró que funciona como una comunidad de práctica donde conviven elementos culturales mapuches y no mapuches. Esto proporciona a los estudiantes mapuches una experi
Este documento analiza las celebraciones indígenas de los mocovíes en la reducción de San Javier durante el siglo XVIII desde una perspectiva etnobotánica histórica. Las celebraciones fortalecían los lazos sociales y las alianzas políticas, pero los misioneros las veían negativamente por el consumo de bebidas fermentadas. Estas bebidas se elaboraban con especies vegetales de la región y tenían un significado cultural importante, aunque los europeos buscaban desterrar las celebraciones. El documento identifica las
Este documento analiza el desarrollo del trabajo de metales en la Araucanía entre 1550 y 1850 d.C., un período de transición entre dos tradiciones: la tradición El Vergel (prehispánica) y la Platería Mapuche (poscontacto). Usa registros arqueológicos e históricos para examinar cambios en materias primas, piezas, individuos y contextos. Propone que hubo un cambio desde el cobre al uso casi exclusivo de plata, y un cambio completo en la morfología de las piezas.
En este trabajo se presentan los resultados de una investigación sobre el asiento de mineral de Pan de Azúcar (sur de Pozuelos, Puna de Jujuy, Argentina), desarrollada en el marco de un proyecto más amplio sobre minería y metalurgia colonial en la región. Se detallan las menciones que sobre Pan de Azúcar hallamos en las fuentes escritas, las evidencias arqueológicas registradas en el campo, y los resultados de los análisis arqueométricos realizados sobre ellas. La explotación del yacimiento se habría iniciado a principios del siglo XVII y continuado de forma intermitente a lo largo de todo el período colonial, generando un poblado que no alcanzó la relevancia de otros centros mineros cercanos, pero que se destaca en el contexto del sur de Pozuelos en relación con la ocupación contemporánea, de carácter básicamente rural y sin acceso a bienes foráneos de raigambre europea.
El fracaso de los enfoques semiológicos aplicados al arte rupestre tiene su origen en el intento de atribuirle un carácter fonémico, es decir, la reducción de la expresión visual a su contenido o expresión verbal. En tanto que la mayoría de los casos rupestres el significado es inaccesible, es claro que el punto de partida debe necesariamente descansar en el significante. En el presente artículo exploramos en una nueva vía de análisis, que apela a un lenguaje intersemiótico que se nutre tanto de la semiótica como de la arqueología. Fundados en este diálogo o arqueosemiótica, consideramos aquí los estilos de arte rupestre como un sistema, como una configuración de significantes distintivos organizados en relaciones, vínculos que constituyen una estructura visual culturalmente significativa. Estas soluciones definen la arquitectura de modos de ver determinados histórica y socialmente, arreglos que distinguen a dos estilos de pintura rupestre de la región atacameña que nos sirven de casos de estudio: los estilos Confluencia (Formativo Temprano 4.000-2.400 a.p.) y Cueva Blanca (Formativo Tardío 2.400-1.600 a.p.).

Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

The femoral neck anteversion (FNA) is defined as the angle between the longitudinal axis of the neck of a femur and the axis passing
horizontally through femoral condyles. However, there is no data regarding this feature in archaeological populations. Therefore,
the aim of this study was to investigate FNA in a medieval skeletal population from Serbia. According to the results the analysed
angle ranged from 11 to 24 degrees in adults, apart from only one individual with significantly increased femoral neck anteversion
of nearly 60 degrees. The discussion of the present paper is focused on the differential diagnosis of this condition and its aetiology,
especially outlining diagnostic limitations when dealing with dry bones. Finally, the most probable aetiology of increased FNA in
our case is the asymmetric form of cerebral palsy. Overall, the traces of various orthopaedic and neuromuscular disorders in past
human populations could be revealed by systematic recording of the femoral neck anteversion during anthropological analyses.
Key words: femoral neck anteversion; medieval skeletal population; cerebral palsy; orthopaedic disorders; neuromuscular
disorders.
Anteversión femoral se define como el ángulo entre el eje cérvico-cefálico y la tangente posterior bicondílea que pasa por el plano
horizontal. Dado que no hay datos sobre el diagnóstico diferencial de esta característica en las poblaciones arqueológicas, la
intención de este estudio fue investigar anteversión femoral (FNA) en los esqueletos de una población medieval de Serbia. Los
resultados demostraron valores de este ángulo de 11 a 24 grados en adultos, pero una persona tenía el ángulo de anteversión
femoral significativamente aumentada (casi 60 grados). En la discusión hemos enfocado en el diagnóstico diferencial de alta
FNA causada por diferente etiología, así como sobre las limitaciones diagnósticas en los huesos secos. La más probable etiología
de aumento de FNA en nuestro caso es la forma asimétrica de parálisis cerebral. Revisión sistemática de la anteversión femoral
puede demostrar las huellas de diversos trastornos ortopédicos y neuromusculares en las poblaciones humanas del pasado.

Schoenecker and Rich (2006) defined the
concept of version as a tilt or inclination within
a bone. Thus, femoral neck anteversion (FNA) is
represented by the angle between the longitudinal
axis of the neck of a femur and the axis passing
horizontally through femoral condyles (Crane 1959;
Fabry et al. 1973). It depicts the degree of rotation
of the femoral neck in reference to the coronal plane
and influences the ability of internal thigh rotation
(Schoenecker and Rich 2006).
The femoral anteversion is a result of fetal
development, heredity, mechanical forces, and
intrauterine position (Guidera et al. 1994). The
value of FNA angle at birth is commonly about 40
degrees and decreases gradually to approximately
20 degrees by the age of 10, to finally achieve value
around 8 to 15 degrees in adulthood (Fabeck et al.
2002; Fabry et al. 1973; Harkess 2003; Hefti et al.
2007; Schoenecker and Rich 2006). It is believed that
physiological decline in torsion of the femoral neck
in children is influenced by dynamic forces produced
during upright walking. Therefore, the magnitude of
anteversion angle is attributed to appropriate motor
control, muscle balance, ligamentous integrity,
2. Ksenija Djukic, Petar Milenkovic, Petar Milovanovic, Milos Dakic and Marija Djuric296
normal ambulation and even unconscious necessity
to position the feet on the ground in parallel (Hefti
et al. 2007; Renshaw and Deluca 2006).
In newborns, Hefti et al. (2007) considered
the value of the FNA above 50 degrees as patho-
logical. The deformity present in childhood, if left
uncorrected, leads to adaptive changes in muscles,
tendons, ligaments, joint capsules and finally to
bone deformities in growing children (William and
Warner 2003a). Higher values of FNA angle can
be caused by different reasons, from fairly benign
and temporary to more severe with long-term con-
sequences (Fabry et al. 1973; Ruby et al. 1979).
Thus, following literature the unilateral presenta-
tion of this condition could be observed in cases
of asymmetric form of developmental dysplasia of
the hip – DDH (Fabry et al. 1973; Fitzgerald et al.
2002; Subasiet al. 2008; Sugano, Noble, Kamaric
et al. 1998), unilateral type of Legg-Calve-Perthes
disease also known as coxa plana (Aufderheide et al.
1998; Thompson and Salter 1987) and various neu-
romuscular disorders.According to the publications,
differential diagnosis of neuromuscular disorders
should involve: hemiplegic cerebral palsy, myelo-
meningocele, chronic stage of poliomyelitis, and
central motoneuron lesions other than cerebral palsy
such as brain or spinal cord tumors or infections
(Beals 1969; Bobroff et al. 1999; Cibulka 2004;
Fabry et al. 1973; Glyn et al. 1966; Heftiet al. 2007;
Lau et al. 1986; Lewis et al. 1964; Morrissy and
Weinstein 2006; Murray and Robb 2006; Noonan

Skinner 2003; Staheli 1977; Tachdjian and Minear
1956; William and Warner 2003a; William and
Warner 2003b).
There are a number of clinical studies about
femoral anteversion focused either on technical
complexity of measuring the angle in patients
(Magilligan 1956; Miller et al. 1997; Murphy et al.
1987; Ruby et al. 1979; Sugano, Noble and Kamaric
1998) or on therapeutic issues (Baker et al.1962;
Beals 1969; Cobeljic et al. 2005).Anthropological
and archaeological studies also mostly focused on
the technical aspects of measuring it in dry bones.
Stirland (1994) noted that very large variations in
measurements have been probably due to two rea-
sons: difficulties in measuring and inconsistency in
the methodology. The study by Shrikant and Arati
(2009) gives comparative data on femoral anteversion
obtained by centre head neck line to retrocondylar
line method toward anterior head trochanter line
to retrocondylar line method. The authors reported
significantly different values between data acquired
by tested two methods.
Heretofore, there are no guidelines for differ-
ential diagnosis of this condition in archaeological
context. Therefore, in this paper we investigated
FNA in the medieval skeletal population and pre-
sented the case with increased femoral anteversion,
focusing on the differential diagnosis and diagnostic
limitations in dry bones.
Material and Methods
The skeletal material investigated in this study
derived from the late medieval cemetery (XII - XIII
CenturyAD) of Pecenjevce – Tapan near the city of
Leskovac, located in the Southern Serbia (Figure 1).
According to the preliminary archaeological
report the cemetery was comprised of 29 graves.

3. 297The increased femoral neck anteversion in medieval cemetery of Pecenjevce. Aetiology and differential diagnosis…
(MNI) was 35.According to the conducted standard
anthropological analysis the demographic distribution
of skeletons involved 17 non-adults (48.57%), and
18 individuals that comprised category of adulthood
whereof 2 were males (5.71%), 8 females (22.86%),
and 8 individuals of undetermined (22.86%). Age
categories were estimated according to the recom-
mendation of Roksandic andAmstrong (2011) while
the sex of the individuals was assessed following
standard criteria of dimorphic features of the os coxae
(Buikstra and Ubelaker 1994).Angle measurement
of the femoral anteversion was done electronically
analysing digital photography by KVI-POPOVAC
Pro software (Version 2.2, Copyright Leica Imaging
Systems). Palaeopathological analysis included
macroscopic observation and radiographic analysis.
Results
Analysis of the skeletal material revealed
that only five adult individuals had completely
preserved femora. The angle of the femoral neck
anteversion in all cases ranged from approximately
11 to 24 degrees, except the skeleton of an adult
woman (Nº 22) with remarkably increased femoral
neck anteversion on the left side. According to the
conducted analyses the age category of individua
Nº 22 was estimated at full adulthood.
The skeleton Nº 22 was relatively well preserved.
The skull, both clavicles and humeri were presented
and in well condition. Among the vertebrae, only
the first, second, fourth, fifth and seventh cervical,
as well as the second and third thoracic vertebrae
were preserved. Both femora were of physiological
morphology, without any traces of trauma and de-
generative disease. Pelvic bones were fragmented
with preserved acetabular surfaces. The right ace-
tabulum was morphologically normal. On the left
acetabulum, the anterior half of the lunate surface
was missing, while the rest appeared normal except
the margin of the acetabulum which was taphonom-
ically damaged. The analyses revealed relatively
well preserved tibiae with fragmented left tibial
plateau. The tarsal bones were presented on both
sides with some post-mortem defects. In addition,
the acquired measurements of the preserved long
bones are given in Table 1.
The left femoral head and neck of the skeleton
Nº 22 were rotated anteriorly with respect to the
plane of the femoral condyles, which caused inter-
nal rotation in the hip joint. The observed femoral
neck rotation resulted in unusual position of the left
femur in the grave (Figure 2). FNA angle on the
left femur was very high – 60 degrees (Figure 3),
while recorded value of the contralateral femur was
relatively low (17 degrees). In addition, the fovea of

the left femoral head was positioned eccentrically,
suggesting subluxation in this hip joint. Furthermore,
no signs of tibial torsion were recorded on the left
body side, and the present tarsal bones were without
clear signs of pathological changes. In addition, the
right clavicle displayed signs of a healed fracture.
Overall, apart from the changes of the proximal
femur and the right clavicle no further evidence of
pathological changes were found.
Discussion
Abnormal femoral anteversionis associated with
clinical manifestations ranging from benign intoeing
gait to severe orthopaedic problems. Table 2 sum-
marizes the morphological characteristics of various
conditions with possible expressed increased FNA
angle.However,anteversioncanalsobehighonbones
unaffected by any other pathological conditions.
One of the main forms of an increased fem-
oral anteversion in childhood is physiological
6. Ksenija Djukic, Petar Milenkovic, Petar Milovanovic, Milos Dakic and Marija Djuric300
Unaltered articular surfaces on the femoral head
ruled out juvenile rheumatoid arthritis as another
possible cause of increased FNA (Harhess 2003).
Therefore, neuromuscular disorder should be
further considered as more appropriate explanation
for high FNA angle of the female skeleton from
Leskovac.
However, we have to note that various neuromus-
cular disorders may be encompassed in differential
diagnosis. One such possibility would be mild
monoplegia observed after meningitis. According
to William and Warner (2003a) there is a very rare
type of paresis which is usually observed after
meningitis, and it is seen in the form of monoplegia.
The authors described such monoplegia as a form of
mild hemiplegia where other ipsilateral extremity
is mildly involved. The results of the skeletal anal-
yses in our case revealed just discrete side-specific
differences in bone size of humeri and increased
FNA of the left femur without any other signs of
limb discrepancy which would be concordant to
such grade of plegia.As the analyses did not reveal
any visible sign of infection on the cranial skeleton,
such specific diagnosis cannot be accepted.
Generally, a question arises about what would
happened if an older individual (adolescent, young
adult or adult) suffered any other type of central
motoneuron damage. We considered this scenario
as well, particularly as the lack of degenerative
joint disease in our case might indicate a shorter
time between the onset of paralysis and the death.
However, although motoneuron lesions in adults
also cause contractures due to muscle imbalance,
it was not possible that it would lead to a change
in the femoral neck anteversion angle from 8-15
degrees to nearly 60 degrees.
During the period of growth any alteration in
child’s ambulation, absence of weight-bearing bone
stimulation or presence of neuromuscular imbalance
caused by a particular pattern of abnormal or spastic
muscle group’s balance may contribute to further
delay or even prevent correction of FNA (Renshaw
and Deluca 2006; Sauser et al. 1986; Shefelbine and
Carter 2004). Furthermore, it has been suggested that
in some cases the same factors could lead to even
increasing FNA from the neonatal value (Renshaw
and Deluca 2006; William and Warner 2003a).
Therefore, childhood neuromuscular lesion
remained the most likely explanation in our case.
The lesions of lower motoneurons (flaccid type of
paralysis), such as poliomyelitis which is usually
(developmental) anteversion. The skeleton from
this cemetery did not meet the main criteria for this
diagnosis (bilateral and symmetric anteversion, and
complete correction of the deformity by skeletal
maturity, Table 2), since the observed FNA angle
was unilaterally increased and the person was of
adult age without correction of the condition.
As it is previously stated, the unilateral presen-
tation can speak in favour of asymmetric form of
developmental dysplasia of the hip – DDH (Fabry
et al. 1973; Fitzgerald et al. 2002; Subasiet al. 2008;
Sugano, Noble, Kamaric et al. 1998), unilateral
type of Legg-Calve-Perthes disease – coxa plana
(Aufderheideet al. 1998; Thompson and Salter
1987) and neuromuscular disorders – hemiplegic
cerebral palsy, myelomeningocele, chronic stage
of poliomyelitis, and central motoneuron lesions
other than cerebral palsy such as brain or spinal
cord tumors or infections (Beals 1969; Bobroff
et al. 1999; Cibulka 2004; Fabry et al. 1973; Glyn
et al. 1966; Heftiet al. 2007; Lau et al. 1986; Lewis
et al. 1964; Morrissy and Weinstein 2006; Murray
and Robb 2006; Noonan 2006; Parsons and Seddon
1968; Renshaw and Deluca 2006; Rogers 1934;
Samilsonet al. 1972; Sauser et al. 1986; Shefelbine
and Carter 2004; Skinner 2003; Staheli 1977;
Tachdjian and Minear 1956; William and Warner
2003a; William and Warner 2003b).
Prominently high value of anteversion angle,
as well as a lack of specific morphological chang-
es of the proximal femur (changes of the femoral
head: deformation, flattening, elongation, irregular
articular surface lower than trochanter, lack of the
fovea capitis, mushroom shape; and the neck: short-
ening, widening and decreased neck-shaft angle)
did not support Perthes disease as an aetiological
possibility in our case.
In unilateral cases of DDH not only is FNA
angle increased on the affected side, but unaffected
side also displays similar or even higher antever-
sion (Fabry et al. 1973). Unilaterally high FNA
angle in our case, as well as lack of morphological
characteristics of DDH (such as small head, short
neck, shallow acetabulum) on either side, made
DDH a rather unlikely diagnosis. In addition, lack
of signs of secondary hip osteoarthritis at adult age
was not compatible with either Perthes disease or
DDH, given the natural progression of those two
conditions which alter biomechanical homeostasis
and frequently lead to premature degenerative joint
disease (Sugano, Noble, Kamaric et al. 1998).
7. 301The increased femoral neck anteversion in medieval cemetery of Pecenjevce. Aetiology and differential diagnosis…
asymmetric and with the known bone deformities
in its chronic phase, also were candidates for the
diagnosis in this skeleton. Given that paralysis due
to poliomyelitis usually occurs before the age of
five (William and Warner 2003b; World Health
Organization), the growth of the proximal femur
is frequently abnormal, leading to coxa valga,
persistent femoral anteversion and other deformi-
ties (Morrissy and Weinstein 2006; William and
Warner 2003b). Osseous growth potential in early
childhood makes children more vulnerable to the
secondary deformities; thus, the worst deformities
develop in young children as well as in those with
severe muscle imbalance (Morrissy and Weinstein
2006). Hence, the effect of poliomyelitis on the
skeleton is thought to depend on the period of
life during which the infection was contracted. If
it happens during childhood when the skeleton is
still developing, the bones in the paralyzed limbs
will be shorter and more gracile than those in the
unaffected limb, and anteversion will be increased.
On the other hand, if the disease is contracted after
skeletal maturity, the bones of the paralyzed limb
or limbs will be of the same length as those on the
normal side; however, they will be more gracile due
to disuse atrophy and will highly unlikely express
such a high anteversion angle. In the paleopatho-
logical literature the childhood poliomyelitic bone
changes on the skeletal remains are ascertained
exclusively on the basis of observing limb length
discrepancy (Waldron 2009), which was not found
in our case. Like in other neuromuscular disorders,
coxa valga, i.e., increased femoral neck-shaft
angle can be found in an affected femur, which
was opposite to the findings from our study. The
lack of degenerative joint disease in the individual
from Leskovac in spite of her advanced age could
speak in favour of poliomyelitis, as poliomyelitis
is thought to be associated with very low incidence
of osteoarthritis (Glyn et al. 1966). However, the
lack of other characteristic features on the skeleton
(Table 2) in our case rebutted against poliomyelitis
as a diagnostic possibility.
Differential diagnosis should also include
myelomeningocele – a complex of congenital mal-
formations of the central nervous system commonly
described as spina bifida (Noonan 2006; William
and Warner 2003b). Sometimes, this disorder can
lead to increased FNA angle (Noonan 2006). This
neuromuscular disorder is depicted as hernia protru-
sion of the spinal cord and its meninges through a
defect in the vertebral canal with consequent variable
neurological defects depending on the location and
severity of the lesion (William and Warner 2003b).
According to Noonan (2006) myelomeningocele
usually occurs in the low thoracic and lumbosacral
regions (affecting function of the lower extremity)
while the cervical region is rarely affected. Given
the poor preservation of the vertebrae and the
absence of other signs (bilaterality and shallow
accetabulum) in our specimen, this diagnosis could
not be established.
Overall, in our case, the most likely diagnostic
possibility was cerebral palsy – a syndrome resulting
from a non-progressive lesion of the developing
brain. Although commonly misunderstood, the
lesion is actually non-progressive since the cause
is acute, but clinical manifestations change as the
brain matures. Cerebral palsy can be caused by
numerous prenatal, perinatal or postnatal factors.
Thus, aetiology is quite diverse: from vascular
reasons and birth head trauma, to infections and
other causes. Furthermore, even nowadays the ac-
curate aetiology could be identified in only 50% of
cases in clinical settings (Berker andYalçin 2005).
Although cerebral palsy is usually diagnosed as any
nonprogressive central nervous system injury which
occurred below the age of two (Berker and Yalçin
2005; Renshaw and Deluca 2006), aetiological
agents could also afflict the central motoneurons
chronologically after the defined age producing
the same clinical manifestations during childhood.
As this differentiation does not have any impact
on further prognosis, most authors refer to both
lesions as cerebral palsy (Renshaw and Deluca
2006). Deformity and displacement of the hip are,
after the equinovarus foot deformity, the second
most common orthopaedic problem in children
with cerebral palsy presenting an increase in the
severity and incidence of hip pathology with the
severity of the palsy (Murray and Robb 2006).
In cerebral palsy, FNA angle could be normal at
birth (Shefelbine and Carter 2004), but would not
decrease with growth (Beals 1969; Bobroff et al.
1999; Fabry et al. 1973) and remains high at adult
age (55 degrees on average: Lewis et al. 1964).
Namely, changes to bone morphology in spastic palsy
occur according to Wolff’s law and bone functional
adaptation principle since the muscle forces acting
on bones govern bone remodelling and development
(Cibulka 2004). In clinical settings, the diagnosis is
straight forward since it takes into consideration the
8. Ksenija Djukic, Petar Milenkovic, Petar Milovanovic, Milos Dakic and Marija Djuric302
history of prenatal, perinatal and early postnatal life
which is usually easily obtained from the parents
of these patients (e.g., birth trauma). Other clini-
cal features of cerebral palsy in its various forms
further make this condition easily distinguishable
from primary bone and joint diseases. However,
considering the lack of data from an archaeological
context, diagnosing cerebral palsy in this case is
quite challenging.
Given that there are two cardinal and two usual
signs on dry bones (Table 2), the morphological
features observed on this adult female skeleton
were compatible with diagnosis of cerebral palsy.
Tachdjian and Minear (1956) already reported
that the degree of coxa valga (increased neck-shaft
angle) in cerebral palsy is proportional to the loss of
muscle power. Normal neck-shaft angle in this case
suggested that the woman did not lose the muscle
power excessively and that she continued to be active.
In cases with neurological deficits, due to disuse of
the paralyzed limbs, it can be expected that the bones
of the affected extremity are more gracile and even
shorter (if the paralysis appeared at an early age),
which was not the case in this woman confirming
that the individual was active. In addition, Renshaw
and Deluca (2006) concluded that FNA values in the
patients with cerebral palsy are higher in ambulatory
than in non-walkers and observed that it does not
change significantly after the age of six.
Comprehensiveanalysisofdiagnosticpossibilities
led us to the most likely explanation of the increased
femoraltorsioninourcase.Moreover,ourstudycould
also serve as diagnostic guidelines for determining
the causes of increased femoral neck anteversion
in further research in archaeological populations.
Conclusion
Analysis of the femoral neck anteversion angle
in a medieval population from Leskovac revealed a
case of unilaterally increased femoral neck antever-
sion indicative of asymmetric form of cerebral palsy.
The differential diagnosis of increased femoral neck
anteversion was under-studied in previous archae-
ological and anthropological literature. Systematic
recording of the femoral neck anteversion could
reveal the traces of various orthopaedic and neu-
romuscular disorders in past human populations.
