This document discusses localized periosteal reactions seen on radiographs in a variety of conditions: 1) Osteogenic sarcoma, Ewing's sarcoma, and lymphoma can present with irregular periosteal responses and bone destruction. Ewing's sarcoma specifically shows laminated and thin periosteal elevations. 2) Chronic leukemia causes pronounced periosteal new bone formation around long bones. 3) Other conditions like aneurysmal bone cyst, chronic osteomyelitis, Reiter's syndrome, vascular stasis, Caffey's disease, syphilis, yaws, and tropical ulcers can also present with periosteal reactions and new bone formation in characteristic patterns.

Periosteal reaction
Periosteal reaction occurs when the periosteum is elevated from the bone cortex in response to various insults like tumors, infections, trauma, or drugs. It can appear as single or multilayered patterns that are solid, spiculated, perpendicular, divergent, or disorganized. Different patterns are associated with certain bone diseases or conditions. For example, a hair-on-end pattern is seen with Ewing sarcoma while a sunburst pattern is seen with osteosarcoma complicating Paget's disease. Codman's triangle, where the periosteum is lifted at the edge of bone formation, indicates osteosarcoma, metastasis, or osteomyelitis.
Imaging in hip disorders
The document discusses various hip disorders that can be imaged radiographically. It describes the anatomy of the hip joint and movements. Various developmental hip disorders are covered like developmental dysplasia of the hip, proximal focal femoral deficiency, and slipped capital femoral epiphysis. Other conditions discussed include Legg-Calve-Perthes disease, transient synovitis, septic arthritis, acetabular fractures, femoral head fractures, and hip dislocations. Imaging features of avascular necrosis, femoroacetabular impingement, and herniation pits of the femoral neck are also summarized.
Presentation1.pptx, radiological imaging of paget disease.
Paget's disease is a chronic bone disorder characterized by abnormal bone remodeling. It commonly affects the pelvis, spine and skull. Radiography is often used to evaluate Paget's disease and detect characteristic features like thickened bone and osteolytic lesions. While some cases are asymptomatic, complications can include fractures, osteoarthritis, nerve entrapment and rare neoplastic transformations. MRI and bone scintigraphy provide additional information about disease activity and complications.

MEDIAL EPICONDYLE FRACTURE BY DR. VASU SRIVASTAVA
A medial epicondyle fracture is an avulsion injury to the medial epicondyle of the humerus; the prominence of bone on the inside of the elbow. Medial epicondyle fractures account for 10% elbow fractures in children. 25% of injuries are associated with a dislocation of the elbow.
Medial epicondyle fractures are typically seen in children and usually occur as a result of a fall onto an out-stretched hand. This often happen from falls from a scooter, roller skates, or monkey bars, as well as from injuries sustained playing sports. The peak age of occurrence is 10–12 years old.[1]
Symptoms include pain, swelling, bruising and a decreased ability to move or use the elbow. Initial pain may be managed with NSAIDs, opioids, and splinting. The management of pain in children typically follows guidelines, such as those from the Royal College of Emergency Medicine.[2]
The diagnosis is confirmed with X-rays and occasionally with a CT scan.
The treatment of these injuries is controversial, and there are currently ongoing international randomised studies. The SCIENCE study is an ongoing study funded by the National Institute for Health Research (UK). A similar study is being planned in the US, funded by the National Institutes for Health (US). These studies both seek to determine if surgery to restore the natural position of the elbow is better than allowing the bone to heal in a cast without restoring the natural position. Children and families internationally are being encouraged to participate in these research studies to resolve the uncertainties.
Benign bone tumors
This document discusses various benign bone tumors. It begins by defining a neoplasm and classifying tumors as benign, potentially malignant, or malignant. It then discusses the epidemiology and classification of benign bone tumors. Specific benign bone tumors discussed in detail include bone island, osteoma, osteoid osteoma, osteoblastoma, chondroma, chondroblastoma, and chondromyxoid fibroma. For each tumor, the document outlines characteristics such as typical age, location, radiographic appearance, and distinguishing features.
Presentation1.pptx, radiological imaging of sacroiliac joint diseases.
This document discusses radiological imaging of sacroiliac joint diseases. It provides details on the anatomy and physiology of the sacroiliac joints, common pathological conditions like infections, and imaging findings on x-ray, CT, and MRI. Key points include that sacroiliac joints are susceptible to arthritis and trauma with age. Plain x-rays remain the most common initial imaging method but CT and MRI can detect changes earlier and better evaluate soft tissues. Common MRI findings in sacroiliitis include bone marrow edema, enhancement, and erosions in the acute phase and sclerosis, pannus formation, and ankylosis in the chronic phase.
Avascular Necrosis
A 41-year-old male presented with right hip, knee, and groin pain that began six months ago after a fall. He was previously treated with high-dose corticosteroids for skin lesions, which likely caused his current avascular necrosis (bone cell death due to interrupted blood flow). Imaging showed abnormalities in his right femoral head consistent with avascular necrosis. He was diagnosed with avascular necrosis likely caused by his past prolonged corticosteroid use.
Pelvis acetabulum - anatomy , imaging , classification
This document discusses pelvic ring fractures, including their epidemiology, anatomy, imaging, and classification. It notes that pelvic fractures are usually due to high-impact trauma and have a 10% overall mortality rate. The pelvis has both anterior and posterior ligamentous supports. Imaging includes x-rays, CT scans, and arteriograms. Several classification systems are described for categorizing fracture patterns based on injury mechanism, including the Young-Burgess system which divides fractures into lateral compression, anteroposterior compression, and vertical shear patterns. The classification helps determine treatment and prognosis, with anteroposterior compression type 3 and vertical shear fractures having the highest transfusion requirements.

Femoroacetabular%20 impingement[1]
This document discusses femoroacetabular impingement (FAI), a condition causing hip pain in young patients due to abnormal contact between the femoral head and acetabular rim. There are two main types: pincer FAI from acetabular overcoverage, and cam FAI from aspherical femoral head morphology. Clinical features include groin pain worsened by flexion and internal rotation. Radiographs and MRI can identify abnormalities like a pistol grip deformity, increased alpha angle, or acetabular retroversion. Treatment involves surgery to address bony abnormalities and prevent early osteoarthritis.
An approach to malignant bone tumors
This document provides an overview of malignant bone tumors, including their classification, occurrence, imaging appearance, and examples. It discusses several primary malignant bone tumors in detail, including osteosarcoma and multiple myeloma. Osteosarcoma most commonly affects teenagers and young adults, presents as aggressive bone destruction with periosteal reaction on x-ray, and has variable appearances on MRI/CT. Multiple myeloma commonly affects older adults, causes lytic lesions scattered throughout the skeleton appearing as "punched out" areas on x-ray, and MRI is most sensitive for detecting its bone involvement. The document outlines radiographic features that can help characterize and differentiate various malignant bone tumors.

Legg-Calvé-Perthes disease is also demonstrated through flattened, fragmented and laterally extruded femoral heads in pediatric patients. Staging of both conditions is discussed.
Shoulder Mri Scan in Delhi by Dr Shekhar Shrivastav
The document discusses MRI findings of the normal and pathological shoulder. It begins by showing coronal, sagittal, and axial views of the normal shoulder anatomy. It then describes common shoulder issues seen on MRI such as impingement, rotator cuff pathology including tendinosis, partial and full thickness tears, instability including Bankart lesions and Hill-Sachs deformities, SLAP tears, biceps pathology, fractures, and infection. For each condition, it highlights the MRI features including location and characteristics of lesions. In conclusion, it emphasizes the importance of MRI in evaluating shoulder problems but notes findings must be consistent with clinical examination.
Remplissage
The document describes a study evaluating the "Remplissage" arthroscopic technique for treating traumatic shoulder instability accompanied by glenoid bone loss and Hill-Sachs defects. The study involved 28 patients who underwent the Remplissage procedure. Post-operatively, patients showed excellent functional outcomes with no reoccurrences of dislocation, nearly full return to work and sports, and significant improvements in shoulder scoring systems. The conclusion is that Remplissage offers excellent short-term results for addressing shoulder instability with humeral bone loss, despite some loss of external rotation.

Evaluation of muscle, labral injuries, bursitis and loose bodies are also covered.
Transient Osteoporosis of Hip
This document discusses transient osteoporosis of the hip (TOH) and differentiates it from avascular necrosis (AVN). TOH typically involves healthy middle-aged men and involves acute hip pain without trauma. MRI findings show bone marrow edema that resolves within 6-8 months. AVN is typically associated with corticosteroid use, alcoholism, or trauma and shows subchondral changes on MRI with sclerosis or collapse not seen in TOH. The document presents five case studies demonstrating the MRI findings of TOH, with bone marrow edema that resolved without sequelae such as sclerosis or collapse seen in AVN.
Imaging of shoulder - Dr. Vishal Sankpal
Here are the key points about rotator interval tears:
- The rotator interval is the space between the supraspinatus and subscapularis tendons through which the long head of the biceps tendon passes.
- Rotator interval tears refer to tears in the capsule in this space between the two tendons.
- They are often associated with instability or repetitive microtrauma and overuse.
- On MRI, they appear as abnormal high signal within the rotator interval capsule on fluid sensitive sequences like T2 or STIR. The torn edges may also enhance with contrast.
- Ultrasound can also identify fluid within the torn interval capsule but MRI is usually better for full
Superior Shoulder Suspensory Complex injuries (SSSC)
This document discusses zonal CME conducted at GSLMC on the superior shoulder suspensory complex (SSSC). It defines the SSSC as a bony and soft tissue ring structure that maintains the stable relationship between the scapula and axial skeleton. Injuries to two structures in the SSSC can cause instability known as the "floating shoulder". Treatment depends on the amount of displacement, with conservative management used for displacements under 5mm and no caudal displacement of the glenoid. Surgical stabilization is recommended for larger displacements or malalignment.

For each type of arthritis, it describes characteristic bone erosions, osteophyte formation, joint space narrowing, subchondral changes, soft tissue abnormalities, and patterns of involvement that are seen on x-ray imaging.
Osteosarcoma Radiology Review
Osteosarcomas are malignant bone-forming tumors that typically occur in the metaphysis of long bones in young patients. They can be primary tumors or develop secondary to conditions like Paget's disease. Patients usually present with bone pain and swelling. Treatment requires aggressive surgical resection and chemotherapy, with the goal of cure. Imaging plays an important role in evaluating tumor extent, involvement of surrounding tissues, and distant staging.

1) Paget's disease is a chronic bone disorder characterized by excessive abnormal bone remodeling that commonly affects older adults, with prevalence increasing from 4% in those over 40 to 11% over 80.
2) It typically involves multiple bones (polyostotic) and bones asymmetrically. Common sites are the pelvis, spine, skull, and proximal long bones.
3) Radiographically, Paget's disease presents with thickened bone cortex, accentuated trabecular pattern, and enlarged bone size ("classic triad"). In the pelvis, thickening occurs along the iliopubic and ilioschial lines. In the spine, vertebrae have a "picture frame"
Hemoglobinopathies
1) Hemoglobinopathies are inherited disorders affecting hemoglobin structure or production, ranging from asymptomatic to fatal. The most common types are sickle cell disease and thalassemias.
2) Thalassemias are caused by deficient production of globin chains, leading to imbalanced globin synthesis and red blood cell damage. Beta thalassemias result from low beta chain production while alpha thalassemias involve alpha chains.
3) Clinical features vary by specific disorder from mild anemia to transfusion-dependent anemia and organ damage. Management involves treatment of complications, transfusions, chelation therapy, and in severe cases, stem cell transplant.

It describes key locations where certain tumors typically occur, the patient's age, the size of the lesion, how the bone is responding, if the lesion is producing a matrix, whether the cortex is eroded, and if a soft tissue mass is present. It then examines patterns of bone destruction, characteristics of periosteal reactions, zones of transition between lesions and bone, and presence or absence of cortical destruction that provide clues about the aggressiveness and benign or malignant nature of the tumor.
Diagnostic Imaging of Endocrine bone disease
This document discusses endocrine bone diseases including hyperparathyroidism, thyroid acropachy, and acromegaly.
Hyperparathyroidism is caused by increased parathyroid hormone levels leading to bone resorption. It can cause generalized osteopenia, Rugger Jersey spine, brown tumors, skull changes like the salt and pepper sign, and rib notching. Thyroid acropachy occurs in some patients with Graves' disease and causes thick periosteal reactions in the hands.
Acromegaly is caused by excess growth hormone secretion leading to gradual bone and soft tissue enlargement. Radiographic features include skull thickening and enlarged sinuses, spade-shaped phal

Cauda Equina Syndrome
Cauda equina syndrome is a surgical emergency that occurs when the spinal canal is significantly narrowed, compressing the spinal cord and nerves below. It causes a variety of symptoms like leg and bladder problems. Early diagnosis and treatment are crucial, as waiting over 24 hours or symptoms worsening requires immediate surgery to decompress the spine. Prognosis depends on the severity and extent of symptoms, with bilateral leg pain or complete groin numbness indicating a poorer prognosis.
Cauda conus syndromes
1. The patient is a 21-year-old male who presents with a 2.5 year history of difficulty urinating, 2 year history of lower back pain, and numbness and weakness in the lower limbs over the past 2 years.
2. On examination, the patient has reduced sensation in the saddle area and lower limbs, weakness in the right lower limb, and wasting of thigh and calf muscles on the right side.
3. Based on the history and examination findings, the patient likely has conus medullaris syndrome, with signs and symptoms consistent with spinal cord compression and dysfunction in the lower lumbar and sacral regions.
