chondrosarcoma Malignant tumor of the cartage.
Developmental Dysplasia of the hip Hip dislocations that are caused by a condition that is present at birth and may require frequent hip radiographs
Legg-calve-perthes disease most common type of aseptic or ischemic necrosis, lesions typically involves only one hip.
Metastatic Carcinoma Malignancy that spreads in the bone via the circulatory system or the lymphatic system, or by direct invasion.
Osteoarthritis Also know as degenerative joint disease. Degeneration of joint cartilage and adjacent bone causing pain and stiffness.
Pelvic Ring Fractures caused by severe blow or trauma to one side of the pelvis may result in a fracture site away from the site of primary trauma.
Proximal Femur Fractures Most common in older adult or geriatric patients with osteoporosis or avascular necrosis.
Slipped capital femoral epiphysis Occurs in 10 to 16 years olds during rapid growth when even minor trauma can precipitate its development.
