We have reviewed a series of 94 Chiari pelvic osteotomies carried out from 1966 to 1982. In 83 hips the indication for surgery had been pain, and of these patients 73 (88%) had appreciable relief within one year of operation. The other 11 hips were all in children and were painless; in them the osteotomy had successfully stabilised progressive subluxation of the hip. At review after a mean follow-up of 10 years (range, 2 to 18 years) 68 previously painful hips were reassessed. Although function of the hips had deteriorated slowly with time, four of the seven cases with 18 years' follow-up had good function and only minor symptoms. A detailed analysis of the radiographic changes produced by the Chiari osteotomy was made, using computerised analysis of variance. The beneficial effects of the osteotomy resulted from complex changes, among which the provision of a stable fulcrum for the hip seemed to be the most important.
我们回顾了1966年至1982年间实施的一系列94例Chiari骨盆截骨术。在83例髋关节手术中，手术指征为疼痛，其中73例（88%）患者在术后一年内疼痛明显缓解。另外11例髋关节手术均针对儿童，且无疼痛症状；截骨术成功稳定了髋关节的进行性半脱位。在平均随访10年（范围为2至18年）后进行复查时，对68例先前疼痛的髋关节进行了重新评估。尽管随着时间推移髋关节功能逐渐恶化，但在随访18年的7例病例中，有4例功能良好且仅有轻微症状。利用计算机方差分析对Chiari截骨术产生的影像学变化进行了详细分析。截骨术的有益效果源于复杂的变化，其中为髋关节提供稳定支点似乎是最重要的。
