Of seventy-three adults who were treated for osteoarthritis of the hip by medial-displacement intertrochanteric osteotomy done by one of us, sixty-one (with sixty-seven treated hips) could be evaluated twelve to fifteen years after osteotomy or at the time when they had an arthroplasty for recurrent symptoms. Specific criteria based on preoperative data were used prospectively to categorize the hips as to their suitability for medial-displacement osteotomy. In addition, at the conclusion of the study, an osteotomy suitability score (maximum score, 12 points) was assessed retrospectively as a determinant of suitability for medial-displacement osteotomy. Ten years after the osteotomy, thirty-four (51 per cent) of the sixty-seven hips had been treated with a cup arthroplasty or total hip arthroplasty. At the conclusion of the study (between twelve and fifteen years after osteotomy), forty-four (66 per cent) of the sixty-seven hips had had an arthroplasty. Among the sixteen hips that had been considered excellent candidates according to the prospective criteria, 85 per cent had not yet required hip arthroplasty five years after osteotomy and two-thirds had not had an arthroplasty ten years after surgery. Of the thirty hips with a suitability score of 7 points or more, 85 per cent had not required arthroplasty at five years and 67 per cent had not done so at ten years. The numerical scoring therefore appeared to be a more reliable determinant of suitability.
在我们中的一人采用转子间内侧移位截骨术治疗的73例成年髋关节骨关节炎患者中，61例（67髋）在截骨术后12至15年或出现复发性症状接受关节置换时可进行评估。根据术前数据制定的特定标准被前瞻性地用于将髋关节分类，以确定其是否适合内侧移位截骨术。此外，在研究结束时，回顾性评估截骨术适用性评分（满分12分），作为内侧移位截骨术适用性的决定因素。截骨术后10年，67髋中有34髋（51%）接受了杯形关节置换术或全髋关节置换术。在研究结束时（截骨术后12至15年），67髋中有44髋（66%）接受了关节置换术。根据前瞻性标准被认为是极佳候选者的16髋中，85%在截骨术后5年尚未需要髋关节置换术，三分之二在术后10年未接受关节置换术。在适用性评分7分或更高的30髋中，85%在5年时不需要关节置换术，67%在10年时未进行关节置换术。因此，数值评分似乎是适用性更可靠的决定因素。
