为了防止或减少股骨头变形，改善髋关节功能，应用骨盆截骨术治疗Ｌｅｇｇ－Ｐｅｒｔｈｅｓ病１６例。其中ＣａｔｔｅｒａｌｌⅢ型病变７例，Ⅳ型病变９例。患儿平均年龄８．２岁，随诊平均时间２８．５个月。－采取临床和Ｘ线片测定，评价术后髋关节功能和形态，结果显示１６个髋关节功能活动均无明显受限，股骨头虽有轻度增大，但仍保持其圆形结构，而且髋臼也因骨盆截骨而增大，使股骨头获得满意的覆盖。骨盆截骨术是治疗Ｌｅｇｇ－Ｐｅｒｔｈｅｓ病确实有效的方法。 In order to prevent or reduce the deformation of the femoral head and improve the function of the hip joint, 16 cases of Legg-Perthes disease were treated with pelvic osteotomy. Catterall Ⅲ type lesions in 7 cases, type Ⅳ lesions in 9 cases. Children with an average age of 8.2 years, the average follow-up time of 28.5 months. - Clinical and radiographic measurements were performed to evaluate postoperative hip function and morphology. The results showed no significant limitation on the functional activities of the 16 hip joints. Although the femoral head slightly increased, its circular structure was maintained, and Acetabular also increased due to pelvic osteotomy, the femoral head to obtain satisfactory coverage. Pelvic osteotomy is a truly effective treatment for Legg-Perthes disease.
