摘要
目的比较发育性髋脱位闭合复位与切开复位的疗效及股骨头坏死发生率。方法分析346例发育性髋关节脱位患儿449髋的资料,依据治疗方式分为闭合复位组(闭合组,209例,293髋)和切开复位组(切开组,137例,156髋)。比较两组患儿手术后6、12个月后的髋臼指数(AI)、髋臼深度与宽度比值(AI D/W)以及股骨头坏死发生率。结果两组术后6、12个月的AI均显著低于术前(P<0.05),两组比较差异无统计学意义(P>0.05)。两组术后6、12个月的AI D/W均显著高于术前(P<0.05),两组比较差异无统计学意义(P>0.05)。股骨头坏死发生率:切开组为34.6%(54髋),闭合组为12.9%(38髋),两组比较差异有统计学意义(P<0.05)。结论发育性髋脱位闭合复位与切开复位临床疗效均较理想,但闭合复位术后股骨头坏死发生率更低。
Objective To compare the clinical effects and femoral head necrosis incidence rate of closed reduction and open reduction on developmental dislocation of hip（ DDH）. Methods A retrospective analysis of 346 children（ 449 hips） with DDH were divided into closed reduction group（ closed group,209 cases,293 hips） and open reduction group（ open group,137 cases,156 hips）. The acetabular index（ AI）,the depth and width of the acetabulum（ AI D/W） before and at 6,12 months after treatment between two groups were compared. And the incidence rate of femoral head necrosis was also compared. Results At 6,12 months after treatment,the AI were significantly lower than that before treatment in both groups（ P〈0. 05）,and AI D/W were significantly higher than that of the preoperation in both groups,for above data,there were no significant difference between two groups（ P〉0. 05）. As osteonecrosis of the femeral head（ ONFH）,there were 34. 6%（ 54 hips） in the closed group,which was significantly higher than 12. 9%（ 38 hips） in the open group,there was significant difference between two groups（ P〈0. 05）. Conclusions Both of closed reduction and open reduction are ideal for DDH treatment,but the incidence rate of ONFH after closed reduction is lower.
