A joint-preserving operation was performed on 15 hips with osteoarthrosis, involving 12 patients who had adult cerebral palsy.
Eleven hips underwent Chiari pelvic osteotomy only; three hips underwent Chiari pelvic osteotomy with femoral osteotomy and the other one hip underwent femoral varus osteotomy only. The mean follow-up period after surgery was 6 years and 2 months (with follow-up range of 2 years and 3 months to 10 years and 6 months).
Good results were achieved in 13 of the 15 hips (86.6%). Two patients with athetotic tetraplegia treated with Chiari pelvic osteotomy had pelvic obliquity. Progressive osteoarthrotic change continued in bilateral hips in one case treated with Chiari pelvic osteotomy.
We confirm that usual treatment for osteoarthrosis of the hip was also applicable for osteoarthrosis of the hip in cases of adult cerebral palsy, provided sufficient attention is given to the complications accompanying spastic paralysis.
