Case 4 Case 4. Some children have a coincidental history of trauma.


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.

The radiographic changes to the femoral epiphyses depend on the severity of osteonecrosis and the amount of time that there has been alteration of blood supply:. Check for errors and try again. 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.
