偏心性髋臼旋转截骨与Chiari截骨治疗髋臼发育不良的短期疗效比较

Short-term effect comparison between eccentric rotational acetabular osteotomy and Chiari osteotomy in the treatment of acetabular dysplasia

目的:比较偏心性髋臼旋转截骨与Chiari截骨治疗髋臼发育不良的短期疗效。方法:将34例成人髋臼发育不良患者随机分为对照组18例和观察组16例。对照组给予Chiari截骨治疗,观察组给予偏心性髋臼旋转截骨治疗。比较2组患者手术时间、术中出血量和切口长度、手术前后日本骨科学会(JOA)评分、中心边缘(CE)角和髋臼(Sharp)角变化及术后并发症发生率。结果:2组患者手术时间、术中出血量和切口长度等指标差异无统计学意义(P>0.05)。2组患者术前JOA评分、CE角和Sharp角差异均无统计学意义(P>0.05),观察组患者术后JOA评分和CE角均显著高于对照组(P<0.01),且Sharp角明显低于对照组(P<0.01)。观察组患者术后并发症发生率与对照组差异无统计学意义(P=1.000)。结论:偏心性髋臼旋转截骨治疗髋臼发育不良短期疗效更优,具有临床应用价值。

Objective： To compare the short-term effects between eccentric rotational acetabular osteotomy and Chiari osteotomy in the treatment of acetabular dysplasia. Methods： Thirty-four adults with acetabular dysplasia were randomly divided into the control group（ 18 cases） and observation group（ 16 cases）. The control group and observation group were treated with Chiari osteotomy and eccentric rotational acetabular osteotomy,respectively. The operative time,blood loss,incision length,JOA score,CE angle,Sharp angle and postoperative complications between two groups were compared. Results： The differences of the operative time,blood loss and incision length between two groups were not statistically significant（ P〉0. 05）. The differences of the preoperative JOA score,CE and Sharp angle between two groups were not statistically significant（ P〉0. 05）. The postoperative JOA score and CE angle in observation group were significantly higher than those in control group（ P〈0. 01）,but for the Sharp angle,it was significantly lower than that in control group（ P〈0. 01）. The difference of the complications between two groups was not statistically significant（ P = 1. 000）. Conclusions：The short-term effect of eccentric rotational acetabular osteotomy in the treatment of acetabular dysplasia is better,which has certain clinical application value.
