Fifty-eight Chiari osteotomies performed in 51 patients were reviewed retrospectively. The indications for surgery were painful subluxation, instability, or poor acetabular coverage. The average age at surgery was 16 years (range, 7-45), and the average follow-up period was 40 months. The majority of the patients had congenital hip dislocation, but also included were patients with cerebral palsy, Legg-Calvé-Perthes disease, polio, infection, coxa vara, and epiphyseal dysplasia. Supplemental bone grafts were applied as needed. The functional results were unrelated to age, with 26 excellent, 28 good, and four poorly functional hips. After operation, 39 out of 41 had total pain relief, 41 out of 58 had a normal acetabular index, and 54 out of 58 had a normal center-edge angle. Trendelenburg gaits were unchanged by the Chiari osteotomy, but trochanteric transfer improved the gait in few cases.
对51例患者实施的58例Chiari截骨术进行了回顾性研究。手术指征为疼痛性半脱位、不稳定或髋臼覆盖不良。手术时的平均年龄为16岁（范围7 - 45岁），平均随访期为40个月。大多数患者患有先天性髋关节脱位，但也包括患有脑瘫、Legg-Calvé-Perthes病、小儿麻痹症、感染、髋内翻和骨骺发育异常的患者。根据需要进行补充骨移植。功能结果与年龄无关，26例髋关节功能优秀，28例良好，4例功能较差。术后，41例中有39例疼痛完全缓解，58例中有41例髋臼指数正常，58例中有54例中心边缘角正常。Trendelenburg步态在Chiari截骨术后无变化，但转子转移术在少数病例中改善了步态。
