In this retrospective observational study, I aimed to report long-term follow-up results of femoral varus osteotomy in the treatment of Perthes disease patients who were between 6 and 8 years old at the onset of the disease with Herring B and C hip involvement. I also aimed to compare 2 different osteotomy techniques: open-wedge and closed-wedge femoral varus osteotomies.Patients with Perthes disease treated with femoral varus osteotomies were invited for final examination. Twenty two hips of 19 patients were evaluated. Mean follow-up period was 15.2 years. Patients were divided into 2 homogenous groups according to femoral osteotomy technique. In Group A (12 hips) open-wedge osteotomy, and in Group B (10 hips) closed-wedge osteotomy was performed.There were 15 male (78.9%) and 4 female (21.1%) patients. The median age at the onset of the disease was 7 years in Group A and B. The mean follow-up period was 16.2 years in Group A, and 11.4 years in Group B. According to Stulberg classification 5 hips (22.7%) were healed as Class I, 4 hips (18.2%) were healed as Class II, 12 hips (55.5%) were healed as Class III, and 1 hip (4.6%) was healed as Class IV. Also in Group A 4 hips (33.3%) were healed as Class I or II, 7 hips (58.3%) were healed as Class III, and 1 hip (8.3%) was healed as Class IV; in Group B 5 hips (50.0%) were healed as Class I or II, and 5 hips were healed as Class III (50.0%). There was no significant difference between the groups. According to Iowa scale, mean values were 92.6 in Group A and 92.4 in Group B. There was no significant difference between the groups. At the final follow-up mean center-edge angles of Group A and B were 16 and 22, the difference was significant.Long-term follow-up results showed that femoral varus osteotomy was an effective treatment method in Perthes disease patients who were between 6 and 8 years old with Herring B and C hip involvement at the onset of the disease. Hip joint congruency was obtained with femoral varus osteotomies, and closed-wedge osteotomy served more favorable center-edge angle results.

：在这项回顾性观察性研究中，我旨在报告股骨内翻截骨术治疗Perrings病患者（发病于6到8岁，患有鲱鱼B和C髋关节）的长期随访结果。我还打算比较两种不同的截骨术：开放式和封闭式股骨内翻截骨术。邀请接受Perthes病的股骨内翻截骨术患者进行最终检查。对19名患者的22髋进行了评估。平均随访期为15。2年。根据股骨截骨术将患者分为2组。 A组（12髋）行楔形截骨，B组（10髋）行楔形截骨，男15例（78.9％），女4例（21.1％）。该疾病发作的中位年龄在A组和B组为7岁。A组的平均随访期为16.2年，B组的平均随访期为11.4年。根据Stulberg的分类，5愈了5髋（22.7％）。 I类为4髋（18.2％），II类为12髋（55.5％），III类为1髋（4.6％）。同样在A组中，有4髋（33.3％）被治愈为I级或II级，有7髋（58.3％）被治愈为III级，有1髋（8.3％）被治愈为IV级。在B组中，有5髋（50.0％）被治愈为I或II级，有5髋被治愈为III类（50.0％）。两组之间无显着差异。根据爱荷华州量表，A组平均值为92.6，B组平均值为92.4。两组之间无显着差异。在A组和B组的最终随访平均中心边缘角度分别为16和22时，差异显着。长期随访结果表明，股骨内翻截骨术是治疗以下两种之间的Perthes病患者的有效方法： 6和8岁，发病时出现鲱鱼B和C髋关节。股骨内翻截骨术可实现髋关节全合，而楔形截骨术可提供更有利的中心边缘角度结果。
