(A) This AP radiograph of the left hip of a 12 year-old patient shows a deformity of unknown etiology with necrosis of the medial portion of the femoral head. Severe subluxation, a short neck and high-riding greater trochanter are apparent, along with secondary acetabular dysplasia. The femoral approach was performed first to reshape the femoral head and allow its relocation into the acetabulum. Again, the first ischial cut of the PAO was executed via the femoral approach. (B) The AP radiograph 18 months after surgery is shown. The remodeled femoral head is well-centered, the neck is longer, the greater trochanter is advanced and the acetabulum is oriented correctly.
