Chiari Pelvic Osteotomy in Cerebral Palsy

Abstract

Hip subluxation and dislocation in patients with cerebral palsy are challenging problems. The Chiari pelvic osteotomy has been commonly recommended as a technique for hip stabilization when acetabular dysplasia is present. We evaluated the results of Chiari osteotomy without concomitant femoral osteotomy in 24 hips in 23 patients with an average follow-up of >7 years. Evaluation consisted of a pain and function questionnaire, chart review, physical examination, and review of serial radiographs.
