Soft tissue release around the hip joint was performed in twenty children (thirty-seven hips) with cerebral palsy. The evaluation of the derangement, methods of lengthening and the amount of each muscles elongated by this methods were studied. The extensor muscles around the hip joint were elongated until extension of the knee joint became 170°. The adductor muscles were elongated until abduction of the hip joint became 40°. The flexsor muscles were elongated until extension of the hip joint became 0°. The mean age at the time of operation was 6.4 years (renge from 3.2 years to 14.5 years) and the mean follow-up duration was 4 years and 6 months. Soft tissues were elongated in all hips by these procedures. Nine Salter's innominate osteotomy, one Chiari's pelvic osteotomy and one resection of the femoral head were added simultaneously. Clinically motor functions were improved in all children and radiological results were satisfactory in all but 5 hip joints. We consider that the amount of elongation of the muscles around the hip joint in cerebral palsy should be decided under general anesthesia at the time of the operation using range of motion of the joint.
