Osteonecrosis generally occurs secondary to abnormal or damaged blood supply to the femoral epiphysis, leading to fragmentation, bone loss, and eventual structural collapse of the femoral head.

The investigation of atraumatic limp will often include a hip ultrasound to look for effusion, but ultrasound is unlikely to pick up osteonecrosis.

Traditionally arthrography performed under general anesthesia with conventional fluoroscopy is performed to assess congruency between the femoral head and the acetabulum in a variety of positions 3. Synonyms or Alternate Spellings: The aim of therapy is to try and maintain good femoroacetabular contact and a round femoral head. The presence of metaphyseal involvement not only increases the likelihood of femoral neck deformity but also make early physeal closure with resulting leg length disparity more likely.

Eventually, the femoral head begins to fragment stage 2with subchondral lucency crescent sign and redistribution of weight-bearing stresses leading to thickening of some trabeculae which become more prominent. As changes progress, the width of the femoral neck increases coxa magna in order to increase weight-bearing support.

Case 7 Case 7. Edit article Share article View revision history. Case 13 Case Prognosis is also influenced by the percentage of femoral head involvement and degree of primary deformity of the femoral head and the secondary osteoarthritic changes that ensue. Some children have a coincidental history of trauma. MRI is increasingly replacing this, in an effort to eliminate pelvic irradiation. Case 6 Case 6. Developmental dysplasia of hip Developmental dysplasia of hip.
