目的 :探讨小儿发育性髋关节脱位 (DDH)的手术治疗方法和效果。方法 :采用 Salter髋骨截骨法 ,髋臼加盖成形术和联合式手术方法共治疗患儿 4 3例 4 7髋。结果 :经 3.5～ 13年 (平均 7.5年 )随访 ,优良率 86 .0 %。结论 :正确选择术式是治疗DDH获得良好疗效的关键 ,而术式的选择要根据主要病理变化并结合年龄进行 ,牵引后股骨头下降的水平可作为股骨短缩截骨参考 Objective: To investigate the surgical treatment of pediatric developmental dislocation of the hip (DDH) and its effect. Methods: Salter hip osteotomy, acetabular capping and combined surgery were used to treat 43 pediatric patients with 47 hips. Results: After 3.5 to 13 years (mean 7.5 years) follow-up, the excellent and good rate was 86.0%. Conclusion: The correct choice of surgical treatment of DDH is the key to good effect, and the choice of surgical procedures should be based on major pathological changes and combined with age, the level of femoral head after traction can be used as a reference for shortening of the femoral osteotomy
