目的:研究分析Chiari骨盆截骨术治疗儿童Legg-Perthes病的手术方法及其疗效。方法:采用Mckay髋关节功能 评定标准对接受该术式治疗的68例患儿进行临床随访、关节功能评定,并比较手术前后髋关节X线片变化。结果:术后临床随 访,髋关节功能优良率达97.06％。手术前后X线片比较,骺高比、髋臼覆盖率有显著性差异。髋臼指数无显著性差异。双侧对 比,负重力矩有显著性差异。结论:Chiari骨盆截骨术治疗儿童Legg-Perthes病,疗效满意,但要掌握其适应证及手术要点。
OBJECTIVE: To study the surgical methods and curative effects of Chiari pelvic osteotomy on children with Legg-Perthes disease. Methods: Sixty-eight children who underwent this surgical procedure were evaluated with Mckay criteria for hip function. The follow-up and joint function were evaluated. The changes of hip radiographs before and after operation were compared. Results: After clinical follow-up, the excellent and good rate of hip joint function reached 97.06%. X-ray films before and after surgery, epiphyseal height, acetabular coverage were significantly different. Acetabular index no significant difference. Bilateral contrast, load moment have significant difference. Conclusion: Chiari pelvic osteotomy for children with Legg-Perthes disease, satisfactory results, but to grasp the indications and surgical points.
