27 bone within-a-bone appearance
The document describes the "bone-within-a-bone" appearance seen on clinical imaging. This appearance is characterized by a miniature inset seen within bones and can be seen normally in neonates. It is also seen in conditions like osteopetrosis where there is sclerosis at the bone end plates. The appearance can also persist from infantile bones into adulthood if the patient received Thorotrast injections as a child or present as transverse growth lines in ill children.
14 calcification of intervertebral disks
Calcification of intervertebral disks can occur due to degenerative disk disease, ochronosis, or ankylosing spondylitis. Degenerative disk disease is seen as anterior osteophytes, narrowing of disk spaces, and calcification in the anterior longitudinal ligament. Ochronosis results in dense laminated calcification of multiple intervertebral disks. Ankylosing spondylitis causes calcification of disks along with squaring of vertebral bodies and calcification of the anterior longitudinal ligament.
4 generalized vertebral otosclerosis
This document contains 6 figures showing examples of generalized vertebral sclerosis seen on imaging studies. Figure 1 shows myelofibrosis with uniform sclerosis of the spine and pelvis. Figures 2A and 2B show osteoblastic metastases from prostate and breast cancers. Figure 3 demonstrates Paget's disease with a picture-frame vertebra. Figure 4 presents a case of osteopetrosis. Figure 5 is an example of fluorosis with diffuse vertebral sclerosis. Figure 6 depicts renal osteodystrophy with a "rugger jersey" appearance of the spine.
3 osteosclerotic vertebral lesions
This document contains 9 figures showing different examples of osteosclerotic vertebral lesions on clinical imaging. The figures demonstrate a variety of conditions that can result in sclerotic changes in the vertebrae including osteoblastic metastases, Paget's disease, chronic osteomyelitis, osteoid osteoma, mastocytosis, osteopoikilosis, melorheostosis, congenital stippled epiphyses, and tuberous sclerosis. Each figure is labeled with the corresponding condition and includes a brief caption.

Pffd
Proximal femoral focal deficiency (PFFD) is a birth defect where the femur is shorter than normal with discontinuity between the femoral neck and shaft. It can be associated with other anomalies. The cause is unknown but theories involve neural crest cell injury or chondrocyte proliferation issues. Treatment depends on the predicted femoral length at maturity and pelvic-femoral stability, with options including limb lengthening, amputation with prosthesis, and rotationplasty or arthrodesis. The goals are to address limb length inequality, joint instability, and functional deficits.
Presentation1.pptx, radiological imaging of anteversion angle.
Femoral anteversion is defined as the angle between the femoral neck and knee joint. In adults, the normal range is 15-20 degrees, but some individuals have angles outside this range which can contribute to orthopedic problems. CT scans are used to precisely measure the femoral anteversion angle by assessing the alignment of the femoral neck and condyles. The summary describes how femoral anteversion is measured and implications of abnormal angles.

Presentation1.pptx. imaging of the cartilage.
1. Imaging modalities such as radiography, ultrasound, CT arthrography, and MRI are used to evaluate articular cartilage and subchondral bone. MRI is the preferred method as it can detect early cartilage degeneration without radiation exposure.
2. Cartilage damage is graded on MRI from Grade I (mild increased signal) to Grade IV (full thickness defects). Subchondral bone changes like edema, fractures, and osteophytes also provide information about the severity and cause of injury or disease.
3. Techniques like dGEMRIC and T1ρ mapping can detect early biochemical changes in cartilage like glycosaminoglycan loss prior to macroscopic defects, helping evaluate and monitor treatments.

Congenital vertical talus
The document discusses the anatomy, etiology, pathoanatomy, clinical presentation, diagnosis, and treatment of congenital vertical talus (CVT). CVT is a rigid flatfoot deformity where the talus is vertically oriented. Treatment involves serial casting to stretch soft tissues, with the goal of restoring normal anatomy. However, most cases require major reconstructive surgery like single-stage releases to reduce the talonavicular joint and correct contractures. Post-surgery, the anterior tibial tendon may be transferred to help stabilize and support the correction. Serial casting alone rarely achieves full correction of CVT.

Blounts disease
Blount's disease is a developmental condition characterized by a disturbance of orderly bone growth in the upper tibia. This results in a varus deformity of the knee. It is more common in obese children who start walking early and has been linked to hereditary factors. Radiographs show a widened growth plate medially with beaking of the metaphysis. Treatment depends on age and severity but may include bracing, corrective osteotomies, or hemiepiphysiodesis in more severe cases. Complications can include recurrence of deformity or nerve palsies. Proper treatment can prevent long term osteoarthritis.

Legg calve perthes disease-UMY
This document summarizes Legg-Calvé-Perthes disease, a childhood hip disorder characterized by temporary loss of blood supply to the femoral head. It describes the disease stages including initial sclerosis, fragmentation as new bone forms, and healing. Risk factors include age 4-8 years and delayed bone age. Symptoms include limping and pain. Treatments aim to contain the femoral head through bracing or surgery to prevent joint damage. Prognosis depends on age and deformity, with older children and severe deformity having worse outcomes.
Perthes disease
Perthes disease is a childhood condition that affects the blood supply to the femoral head, causing bone death (avascular necrosis). It most commonly affects boys between ages 4-8. While the disease process is self-limiting, it can have permanent effects on the femoral head shape and hip function. Treatment aims to contain the femoral head within the acetabulum during healing to promote proper reshaping, through nonsurgical means like bracing or surgical options like osteotomies if needed. The long-term outcomes are evaluated using classifications like Stulberg or Mose, with the goal of achieving a spherical femoral head congruent with the acetabulum. Management approaches vary between centers based on each child's severity and prognosis
Slipped Capital Femoral Epiphysis
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
Osteotomies around the hip -sid
An osteotomy is a surgical procedure to correct biomechanical alignment of the extremity. Osteotomies around the hip can be femoral or pelvic osteotomies. Femoral osteotomies include intertrochanteric, subtrochanteric, and greater trochanteric osteotomies. Pelvic osteotomies include Salter, Pemberton, Steel, and Chiari osteotomies. Osteotomies are used to treat conditions like osteoarthritis, developmental dysplasia of the hip, osteonecrosis, and fractures. Common femoral osteotomies described were Pauwels' varus and valgus osteotomies, and Sugioka
