[Open reduction with pelvic osteotomy and femoral shortening]

The combined procedure of femoral shortening, reduction of the hip, iliac osteotomy, transfer of the iliopsoas muscle, and redirection of the femoral head, applied in 225 hips of children over the age of 7, gave good results in two-thirds of the cases, and poor in one-tenth. The quality of the outcome diminished with increasing age at surgery.
