We performed a retrospective clinical and radiographic review of the long-term results of 64 hips in 53 patients who underwent intertrochanteric varus osteotomy for arthrosis of the hip at the pre- or early stage with acetabular dysplasia. Their average age at operation was 26 years. The average duration of follow-up was 18 years and 10 months. The mean Harris hip score was 77 +/- 9 points pre-operatively, and improved significantly to 84 +/- 13 points at the final follow-up. The acetabular coverage influenced the final outcome, and the postoperative prognosis was predictable from the acetabular head index (AHI) on a pre-operatively done hip maximum abduction radiograph (abd XP). We conclude that varus osteotomy for a dysplastic hip should be considered when the acetabular coverage is sufficient, and that a good prognosis can be expected when AHI on abd XP is greater than 60%.
我们对53例患者的64髋进行了回顾性临床和影像学评估，这些患者因髋臼发育不良处于髋关节疾病的前期或早期而接受了转子间内翻截骨术。他们手术时的平均年龄为26岁。平均随访时间为18年10个月。术前Harris髋关节评分平均为77±9分，在最后一次随访时显著提高至84±13分。髋臼覆盖情况影响最终结果，并且可以根据术前髋关节最大外展X线片（abd XP）上的髋臼头指数（AHI）预测术后预后。我们得出结论，当髋臼覆盖足够时，应考虑对发育不良的髋关节进行内翻截骨术，并且当abd XP上的AHI大于60%时，可以预期有良好的预后。
