Treatment of the chronically dislocated hip in adolescents with cerebral palsy with femoral head resection and subtrochanteric valgus osteotomy.

Femoral head resection with valgus subtrochanteric osteotomy was performed on six hips in five nonambulatory adolescent patients with painful, chronically dislocated hips due to spastic paralysis. This procedure was successful because it led to pain relief, ease of perineal care, and facility of seating. Complications, such as proximal migration of the remaining femur, recurrence of adduction deformity, hip stiffness, and excessive heterotopic bone formation, common to other procedures used for this condition, have not occurred.
