The authors present their experience of the use of intertrochanteric osteotomy for the treatment of idiopathic necrosis of the head of the femur. The results obtained from 102 osteotomies performed on 81 patients with the disease are analysed. The mean follow-up is 4.2 years. The results show a statistically significant clinical improvement after operation. Patients presenting with Ficat and Arlet Stage II involvement fared much better than those with more severe changes. Better results were also seen in those with a necrosis angle of less than 200 degrees. No radiological improvement was seen although a high percentage showed no deterioration. The choice of treatment for the condition is discussed in the light of these results.
作者介绍了他们使用转子间截骨术治疗特发性股骨头坏死的经验。对81例患有该疾病的患者进行的102次截骨术所获得的结果进行了分析。平均随访时间为4.2年。结果显示术后临床改善具有统计学意义。处于菲卡特和阿莱特二期病变的患者比病变更严重的患者预后要好得多。坏死角度小于200度的患者也有更好的结果。尽管有很高比例的患者没有出现恶化，但未观察到放射学上的改善。根据这些结果对该疾病的治疗选择进行了讨论。
