We performed the Chiari pelvic osteotomy on 230 hips with acetabular dysplasia between 1970 and 1986 at Kobe University Hospital. A supplementary procedure was also occasionally performed. Excluding the combined surgery cases, 131 hips were examined 3 to 16 years later (average follow-up: 7.1 years). Follow-up results were assessed using the hip score of the Japanese Orthopaedic Association. The best results were obtained in cases of prear-throsis and early osteoarthrosis in patients under 50 years. This osteotomy was an effective procedure for severe acetabular dysplasia with respect of relief of pain, improvement of gait, and ADL. The decision to perform this osteotomy is dependent upon the biomechanical evaluation of effectiveness, as there are both advantages and disadvantages.
