Femoral and pelvic osteotomy combined with muscle release were chosen in the management of the secondary structural changes in the hips of cerebral palsy. Five adults with seven involved hips (group A) had osteoarthritic changes, and two children with four hips (group B) suffered from nonambulatory quadriplegia. Muscle release and femoral osteotomy were performed for both groups, in addition to spherical acetabular osteotomy in the A group without growth potential of the acetabulum, and Pemberton's osteotomy for the acetabulum in the B group. The mean follow-up period was 2 years and 9 months in group A and 1 year and 6 months in group B.
Clinical and roentgenographic results are generally satisfactory in both groups. Acetabular procedures with muscle release are very important in joint stability for severe subluxation or dysplasia of the hips in cerebral palsy.
