Seventy-eight hips with Perthes' disease (LCPD) were treated with an intertrochanteric varus osteotomy. The hips were preoperatively graded according to Catterall's classification. There were 7 Group II, 32 Group III, and 39 Group IV hips. Good results occurred in 5 of the Group II hips, 19 of the Group III hips, and 12 of the Group IV hips. The average age of the patients at the onset of symptoms was 6 years and 6 months, and the average age at the time of the osteotomy was 7 years and 8 months. This means that the average age of patients was high and that the operations were performed in a late state of the disease. A control group consisting of 52 hips was treated conservatively with a Thomas splint. In 11 hips classified as Catterall's Group IV, there were 8 poor results. The results indicate that with osteotomy the results improve in Group IV of Catterall's classification. There are, however, still about 30% poor results in the Group IV. A prolonged prevention of weight-bearing after osteotomy may be indicated in patients with unfavorable results.
78例患有佩特兹病（儿童股骨头缺血性坏死，LCPD）的髋关节接受了转子间内翻截骨术治疗。术前根据卡特拉尔分类法对髋关节进行分级。其中II组7例，III组32例，IV组39例。II组髋关节中有5例、III组中有19例、IV组中有12例取得了良好效果。患者出现症状时的平均年龄为6岁6个月，截骨时的平均年龄为7岁8个月。这意味着患者的平均年龄较大，手术是在疾病的晚期进行的。由52个髋关节组成的对照组采用托马斯夹板进行保守治疗。在11例被分类为卡特拉尔IV组的髋关节中，有8例效果不佳。结果表明，通过截骨术，卡特拉尔分类法IV组的治疗效果有所改善。然而，IV组中仍有约30%的效果不佳。对于效果不佳的患者，可能需要在截骨术后延长预防负重的时间。
