Abstract
Sixty-three patients with cerebral palsy underwent proximal femoral varus derotation osteotomy for 86 subluxing or dislocating hips. Eleven hips underwent concomitant pelvic osteotomy. Adductor tenotomy was performed in all patients. The average pre-operative femoral neck shaft angle was 158.2°, with a center edge angle of -2°. Femoral osteotomy effected an averge femoral neck shaft angle of 132.2°, with a center edge angle of +8°. A Chiari osteotomy was performed when the acetabular index was > 35°. This preoperative acetabular index of 46° improved to 28° postoperatively, and proved to be the most reliable indicator for need of an added pelvic osteotomy.
