Resection of the proximal end of the femur and interpositional
arthroplasty was done in thirty-four patients (fifty-six hips) to allow the
patients to sit comfortably and to make perineal care painless. All of the
patients were severely handicapped because of cerebral palsy, were unable
to walk, and were residents of one of two state institutions. After a
minimum follow-up of two years, the result had not deteriorated in
thirty-three of the thirty-four patients.
