title: Late results of Chiari's pelvic osteotomy. A follow-up of 171 adult hips.
abstract: Between 1971 and 1985, 461 adult patients were treated by Chiari's pelvic osteotomy with medial displacement. Of these, 161 patients (171 hips) were followed up for an average of 9 years. The average age at operation was 29 years. We describe five groups of painful dysplastic hips in which the operation is indicated. Clinical evaluation by Colton's rating system gave 84% of excellent, good or fair results. Radiographs showed that the secondary osteoarthritic changes were arrested in 73%, improved in 11% and that there was deterioration in 16%. Pain was largely or completely relieved in 87%, the range of movement was maintained in 80% and the gait improved in 77% of our cases. The late results were better in younger patients. We conclude that improved biomechanical conditions are responsible for good congruency of the joint which is preserved for a long time.
