Ankle fractures in children 2021
This document discusses ankle fractures in children. It provides details on:
1) The unique anatomy of the child's ankle including the physis and its development over time.
2) Common fracture patterns seen in children of different ages depending on the stage of osseous development.
3) The importance of achieving adequate reduction and protecting the physis to avoid growth alterations or deformities.
4) Guidelines for diagnosis including physical exam, imaging like x-rays and CT, and classifications systems like Salter-Harris that influence treatment and prognosis.
Slide pfof
A 75-year-old woman presented with left buttock pain for several weeks. Her physical examination was normal except for a slight limp. Initial x-rays suggested a possible hip fracture, and an MRI confirmed a nondisplaced femoral neck fracture. While some hip fractures are obvious on x-rays, others can be more difficult to diagnose, especially if nondisplaced. Careful examination of the patient's history and use of additional imaging like MRI may be needed to identify fractures when pain persists but x-rays do not show an obvious fracture.
Congenital skeletal limb deficiences
in this ppt i have tried to simplify the congenital deformities upto my knowledge ,, hope helps most of the orthopaedic surgeons & post graduates..
Quadriceps fibrosis after intramuscular injections in children.
The intramuscular injections are the most common cause leading to fibrosis of quadriceps in developing countries, also in Cambodia, the injections are applied most health care providers in the country. The complications are not exceptional.
Extraarticular later hindfoot impingement with ptt tear mri correlation
This study aimed to correlate MRI findings of lateral hindfoot impingement with the grade of posterior tibial tendon tears and severity of hindfoot valgus. The study found that 37% of patients with posterior tibial tendon tears showed evidence of lateral hindfoot impingement on MRI. Impingement was associated with more advanced tendon tears and increased hindfoot valgus. Peroneal tendon subluxation was present only in patients with advanced hindfoot valgus and impingement. The findings suggest lateral hindfoot impingement is related to posterior tibial tendon dysfunction and increased hindfoot valgus.
Monteggia fracture & galeazzi fracture
A Monteggia fracture involves a break in the proximal ulna shaft combined with dislocation of the radial head. It most commonly occurs in children following a fall on an outstretched hand. Treatment involves closed or open reduction of the radial head and restoration of the ulna length, with casting or plating depending on patient age. Complications can include nerve injuries or radial head instability.
A Galeazzi fracture is a break of the radius near the middle-distal junction with disruption of the distal radio-ulnar joint. It typically results from a fall onto an outstretched, pronated forearm. Treatment is always surgical via open reduction and internal fixation of the radius and potential K-wiring or
Aneurysmal Bone Cyst of the Spine | Crimson Publishers
A 35yrs young patient, presented to the hospital with lower extremities neurological deficit, radiological investigation showed bony lesion in the posterior elements of T10 causing severe compression on the cord, emergency surgery was performed to decompress the spinal cord, the microscopic examination revealed that lesion was “ aneurysmal bone cyst”.
Meniscal injuries
This document provides an overview of MRI of the menisci. It begins with normal meniscal anatomy, describing the shapes and attachments of the medial and lateral menisci. It then discusses the functions of the menisci, appropriate MR techniques, and various types of meniscal injuries and degenerations that can be seen on MRI such as vertical, horizontal, longitudinal, radial, and root tears. It provides descriptions of signs that indicate these different types of tears on MRI. It concludes with an overview of indirect signs of meniscal pathology like extrusion, cysts, and subchondral bone marrow edema.

MRI IN FOOT PAIN
MRI is useful for assessing soft tissues, vessels, and sometimes bones in the foot, which is a complex structure with over 26 bones, muscles, and ligaments. The document describes several cases where MRI provided valuable information: a case of suspected cuboid pathology where MRI found peroneus longus tendonitis; a non-healing foot ulcer where MRI discovered a foreign body; a case of plantar fasciitis where MRI is not usually needed but can detect fascia rupture; and a diabetic foot where MRI demonstrated osteomyelitis and septic arthritis. The document emphasizes that MRI is effective for evaluating diabetes-related foot infections and distinguishing neuropathic from infectious causes.
Open debridement and radiocapitellar replacement in primary and post-traumati...
Background: Postmortem and clinical studies have shown an early and prevalent involvement of the radiohumeral
joint in primary and secondary arthritis of the elbow. The lateral resurfacing elbow (LRE) prosthesis
has recently been developed for the treatment of lateral elbow arthritis. However, few data have been
published on LRE results.
Materials and methods: A prospective multicenter study was designed to assess LRE preliminary results.
There were 20 patients (average age, 55 years). Preoperative diagnosis were primary osteoarthritis in 11
and post-traumatic osteoarthritis in 9. All patients underwent open debridement and LRE prosthesis.
Patients were evaluated preoperatively and postoperatively with the Mayo Elbow Performance Score
(MEPS), modified American Shoulder Elbow Surgeons (m-ASES) elbow assessment, and the Quick
Disabilities of the Arm, Shoulder and Hand (Quick-DASH). Mean follow-up was 22.6 months.
Results: At the last follow-up, the mean improvement of MEPS and m-ASES was 35 (P ¼ .001) and 34
(P ¼ .001) respectively; the average Quick DASH decreased by 29 (P ¼ .001). Average range of motion
was improved by 35 (P ¼.001). MEPI results were excellent in 12 patients, good in 2, and fair and poor in
3 each. Mild overstuffing was observed in 5 patients, and an implant malpositioning in 3. The implant
survival rate was 100%.
Conclusion: LRE showed promising results in this prospective investigation. Most patients had an
uneventful postoperative course and have shown a painless elbow joint, with satisfactory functional
recovery at short-term follow-up. Further studies with longer follow-up are warranted.

MRI kolano cz.1
The document discusses an upcoming MRI knee course. It provides an outline of topics to be covered in Part 1, including radiological anatomy, protocols, joint spaces, menisci, effusions, cartilage, bones, and marrow edema. Common injuries like bone contusions and fractures will be examined. Participants will analyze example cases and receive feedback to improve diagnostic skills. Recommended articles on knee MRI are also provided. The course aims to help participants better understand knee MRI through interactive workshops and self-study materials.
Neck of Femur
This document discusses pediatric femoral neck fractures. Key points:
- They are rare, accounting for less than 1% of pediatric fractures. Anatomy and blood supply make complications like avascular necrosis more common.
- Delbet classification includes 4 types based on fracture location. Type 1 is through the physis, Type 2 through the neck, Type 3 at the base of neck, and Type 4 is intertrochanteric.
- Treatment depends on type and stability but generally involves closed or open reduction and fixation or spica casting. Complications include avascular necrosis, coxa vara, premature physeal closure, and nonunion. Close follow up is needed due to risk of late complications.
Radio ulnar synostosis #dr_azanki
1. A 44-year-old shoe maker presented with inability to rotate his right forearm following a 2016 car accident that resulted in an open fracture of his right proximal ulna that was plated 10 days after the injury.
2. Examination and imaging showed a bony bridge between the radius and ulna, known as a radio-ulnar synostosis.
3. Risk factors for developing post-traumatic radio-ulnar synostosis include open fractures, surgery delayed more than 2 weeks, screws penetrating the interosseous membrane, and prolonged immobilization, all of which applied to this patient.
Pediatric Congenital Forearm and Elbow
This document discusses congenital problems of the forearm and elbow, including amputations, radioulnar synostosis, and embryology. It notes that amputations below the elbow are the most common transverse deficiency and are rarely associated with other anomalies. Radioulnar synostosis occurs when the radius and ulna fail to separate during development. It describes two types and notes that surgery through osteotomy may be used to improve pronation when fixed at over 60 degrees, but mild cases under 30 degrees often do not require treatment. The document reviews embryology and postnatal development of the elbow region.
AHSS Registrar Review Course. Scaphoid and carpal fractures
- Scaphoid fractures occur most commonly in young males due to falls on an outstretched hand. Location and degree of displacement affect stability and union rates.
- CT imaging with parasagittal views of the scaphoid aids in determining fracture stability and configuration to guide treatment.
- Treatment options include casting for undisplaced fractures or open reduction and internal fixation using a variable-pitch screw for displaced fractures to restore alignment and compression.
- Other carpal bone fractures have specific mechanisms of injury and surgical treatment is indicated for displaced or unstable fractures to address carpal instability or restore joint congruity.
Distal radioulnar joint injuries
This document discusses distal radioulnar joint (DRUJ) injuries. It begins by providing background on the anatomy and biomechanics of the DRUJ. It then describes the clinical evaluation and various imaging modalities used to assess DRUJ injuries. The document presents classifications for triangular fibrocartilage complex injuries and DRUJ injuries associated with fractures. Treatment options are discussed, including non-operative treatment, arthroscopic and open surgical procedures. Specific injuries like isolated DRUJ dislocations, ulnar styloid fractures, Galeazzi fracture-dislocations, and chronic DRUJ instability are also reviewed.
An Atlas of Musculoskeletal Oncology: Volume 2
This document discusses several cases of classic osteosarcoma. It begins with case 108, describing a 16-year-old male with classic osteosarcoma in the femur. It then moves to case 451, describing a 17-year-old male. Several other cases are then summarized, describing patients of varying ages with classic osteosarcoma located in different bones including the femur, tibia, fibula, and humerus. For each case, relevant imaging, specimens, and treatments are briefly discussed.
Rheumatoid arthritis hand
Rheumatoid arthritis (RA) is a chronic inflammatory disease that primarily involves the small joints of the hands and feet. The exact cause is unknown but autoimmunity is suspected. RA results in painful and deforming changes to the joints. It is classified based on the patient's functional ability. Hand deformities are common in RA and include swan neck, boutonniere, and Z-thumb deformities. Surgical treatment depends on the type and severity of deformity and aims to relieve pain and improve function.
Imaging of foot in non trauma and non neoplastic diseases
The document discusses the radiologic evaluation of the foot. It begins by describing the complex anatomy of the foot and various pathologies that can occur. It then discusses the sequence of ossification in the foot bones during fetal development. Various imaging modalities for evaluating the foot are described including radiography, ultrasound, CT, and MRI. Common congenital variants, abnormalities, tendon pathologies and other conditions involving the foot that can be assessed with imaging are outlined.
Vol 1 ppt
This document provides a summary of 50 cases of osteoid osteoma and osteoblastoma. Case 1-50 cover osteoid osteoma, with the classic presentation of a painful nidus most commonly in long bones that is diagnosed using imaging such as CT scan and bone scan. Case 51-94 cover osteoblastoma, a larger variant of osteoid osteoma that is treated surgically via curettage. The remainder of cases provide further examples and variations of these two conditions.
Tmj joint imaging
This document discusses various radiographic techniques for imaging the temporomandibular joint (TMJ). It provides details on anatomy seen with different views like transcranial, transpharyngeal, panoramic. Computed tomography and MRI allow visualization of bony and soft tissues like the articular disc in multiple planes without repositioning. Each imaging modality has advantages and limitations for evaluating TMJ conditions like fractures, arthritis, disc displacement, and tumors. Proper patient positioning and technique selection are important for accurate diagnosis.
Tumor mega prosthesis
- The document discusses principles of limb salvage surgery for bone tumors. It covers staging of tumors, including radiological and surgical staging. Radiological modalities like CT, MRI, PET scans help determine tumor extent and metastases.
- Principles of biopsy and factors affecting success of limb salvage surgery are outlined. Surgical resection aims to remove the tumor with an adequate margin while reconstructing the limb functionally. Pre-operative staging and adjuvant therapy can aid resectability.
- The goal of limb salvage surgery is a painless, functional reconstructed limb while achieving oncologic control.
Meniscal pathology
This document discusses the anatomy, biomechanics, and pathology of the meniscus in the knee. It begins by describing the structure and functions of the meniscus, including its role in load distribution, shock absorption, and joint stability. It then covers the different types of meniscal tears, categorized by their orientation (horizontal, longitudinal, radial). Imaging techniques for identifying meniscal tears are discussed, along with clinical exams. Finally, the document outlines treatment approaches, including non-surgical management and surgical options like meniscectomy, repair, and transplantation.

El documento habla sobre cómo determinar la telediástole cardiaca. Se determina realizando un clip del corte de 4 cámaras y evaluando hasta que se produce el primer movimiento sistólico descendente de la válvula tricúspide o mitral, seleccionando el cuadro anterior al movimiento.
Relación tímico torácica
El documento proporciona mediciones del timo y del mediastino. El diámetro anteroposterior promedio del timo es de 0.44 ± 0.043 cm. Se mencionan condiciones como la síndrome de DiGeorge y la hipoplasia/aplasia tímica que afectan el desarrollo del timo.
Screening cardiopatías congénitas
Este documento proporciona una estrategia para el diagnóstico de cardiopatías congénitas en el feto y recién nacido. Recomienda realizar ecografías fetales de cribado entre las 11-14 y 20-22 semanas para evaluar la estructura y función cardíaca. También sugiere ecocardiografías fetales dirigidas entre las 13-16 y 20-22 semanas para fetos de alto riesgo. Finalmente, recomienda una ecocardiografía neonatal para confirmar cualquier hallazgo.
Imagen quística intraabdominal
El documento presenta una lista de posibles diagnósticos diferenciales para una imagen quística intraabdominal en un recién nacido, incluyendo quistes simples, vena umbilical dilatada o duplicada, várice de vena umbilical, quiste de colédoco, atresia o estenosis duodenal, duplicación intestinal, quiste mesentérico, quiste uracal, enfermedad de Hirschprung y atresia anorectal. También menciona quistes de ovario como un diagnóstico diferencial si el fenot
Imagen sólida intraabdominal
Este documento describe varias posibles anomalías que podrían observarse en una ecografía abdominal. Incluye términos como calcificaciones hepáticas, peritonitis meconial, tumores renales, esplénicos y hemorrágicos, así como hemangiomas e hiperecogénicos intraabdominales.
Circunferencia gástrica
La circunferencia gástrica promedio en fetos con atresia esofágica sin fístula es de 0.9 mm, mientras que en fetos con atresia esofágica con fístula es de 33.8 mm, significativamente menor que la circunferencia gástrica promedio normal de 43.0 mm.
Fistula traqueoesofágica/AE: Que buscar
Este documento describe la detección prenatal de la fistula traqueoesofágica y la atresia esofágica. Explica que la fistula traqueoesofágica y la atresia esofágica pueden ocurrir solas o como parte del síndrome VACTERL, que incluye anomalías vertebrales, anales, cardiacas, traqueoesofágicas, renales y de extremidades. También discute que la atresia esofágica puede presentarse con el síndrome CHARGE.
Gastrosquisis: Muerte intrauterina según EG
La tasa de muerte fetal intrauterina por cada 100 gestaciones con diagnóstico de gastrosquisis es de 1. La gastrosquisis es una malformación congénita en la que los intestinos o parte de ellos se desarrollan fuera del abdomen del feto a través de una abertura en la pared abdominal. El diagnóstico prenatal de gastrosquisis permite un seguimiento más estrecho del embarazo y un parto programado en un centro especializado para mejorar el pronóstico neonatal.
Gastrosquisis: GPS
This document describes a scoring system called the Gastroschisis Prognostic Score (GPS) that is used to predict outcomes for infants born with gastroschisis. The GPS assigns points based on factors present at birth like intestinal atresia, perforation, and necrosis. A score of 1 or less indicates low risk while a score of 2 or more indicates high risk. The GPS aims to help clinicians determine which infants are likely to have more severe outcomes and require longer hospitalization so that care can be tailored appropriately.
Onfalocele: pronóstico
El documento discute si la relación del diámetro del omphalocele en relación al perímetro cefálico (CA) puede predecir los resultados posteriores al nacimiento. El estudio encontró que una relación de 0,26 o menos entre el diámetro del omphalocele y el CA se asoció con resultados normales, mientras que una relación mayor predijo resultados adversos.

Breast cancer: Post menopausal endocrine therapy
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.

What are the different types of Dental implants.
Are you looking for a long-lasting solution to your missing tooth?
Dental implants are the most common type of method for replacing the missing tooth. Unlike dentures or bridges, implants are surgically placed in the jawbone. In layman’s terms, a dental implant is similar to the natural root of the tooth. It offers a stable foundation for the artificial tooth giving it the look, feel, and function similar to the natural tooth.
