We reviewed the results of 277 intertrochanteric valgus-extension osteotomies performed between 1973 and 1975 for primary or secondary osteoarthritis. The average age of the patients was 51 years and follow-up varied from 11 to 15 years. At the latest evaluation 67% of the hips were good or excellent on the Merle D'Aubigné scale. Better results were obtained in patients under 40 years of age with unilateral involvement and a mechanical (secondary) aetiology. An elliptical femoral head, minimal subluxation and an adequate pre-operative range of motion were also favourable. There was radiographic evidence of regression of the arthritic changes in 39% of the hips at final review. Valgus-extension osteotomy is effective for secondary osteoarthritis of the hip in selected younger patients, but not for those with primary hip disease or a poor range of movement.
我们回顾了1973年至1975年间为原发性或继发性骨关节炎实施的277例粗隆间外翻伸展截骨术的结果。患者的平均年龄为51岁，随访时间为11至15年。在最近一次评估中，根据Merle D'Aubigné评分标准，67%的髋关节结果为良好或优秀。40岁以下、单侧受累且病因是机械性（继发性）的患者取得了更好的结果。椭圆形股骨头、最小程度的半脱位以及术前足够的活动范围也较为有利。在最终复查时，39%的髋关节有影像学证据表明关节炎变化出现了消退。外翻伸展截骨术对部分选定的年轻患者的继发性髋关节骨关节炎有效，但对原发性髋关节疾病或活动范围较差的患者无效。
