Salter骨盆截骨术对发育性髋关节脱位的效果研究

The effects of Salter innominate osteotomy for developmental dysplasia of the hip

目的分析Salter骨盆截骨术对发育性髋关节脱位(DDH)的效果。方法选取因DDH就诊并接受Salter骨盆截骨术的患儿作为研究对象,分别测量患儿术前、术后6周、术后1年、术后2年和末次随访的髋白指数(AI)以及患儿术后6周、术后1年、术后2年和末次随访的中心边缘角(CEA),分别用Mckay和Severin分级标准进行优良率分析。根据Severin分级结果,运用SPSS 22.0进行两独立样本t检验和二分类Logistic回归分析,比较不同组别的指标差异,并探索其影响因素。结果AI术后6周改善幅度均最大,AI术后1年改善了20.53°,CEA术后6周至术后1年改善了3.86°。根据Mckay评价标准,术后优良率为97.10%。根据Severin分级标准,优良率为94.20%。优良组术后6周、术后1年和末次随访的AI、CEA均优于中差组。性别、手术年龄、左右髋均非治疗效果的影响因素。结论Salter骨盆截骨术对发育性髋关节脱位的疗效显著。

Objective To analyze the effects of salter innomninate osteotomy on developmental dysplasia of the hip.(DDH).Methods Children who received salter innominate osteotomy with DDH were chosen as research objects.Acetabular index(AI)was measured at preoperation,6 weeks,1 year,and 2 years after operation and the last fol-low-up.Center-edge angle(CEA)was measured at 6 weeks,1 year and 2 years after operation and the last fllow-up.Classification was carried out in line with Severin and Mckay classification standard.According to the results of Severin's classification,SPSS 22.0 was used for two independent samples t-test and binary logistic regression anal-ysis to compare indicator differences among different groups and explore the influencing factors.Results The inm-provement of AI was the greatest at 6 weeks after operation.AI improved by 20.53°at 1 year after operation,and CEA improved by 3.86°from 6 weeks to 1 year after operation.Excellent and good rate was 97.10%according to Mckay classification standard.Excellent and good rate was 94.20%according to Severin clasification standard.The AI and CEA of the excellent and good group were better than those of the medium and poor group at 6 weeks,1 year and the last follow-up.Gender,age of operation and the side of hip were not the influencing factors of thera-peutic effect.Conclusion Salter inmnominate osteotomy is a very effective way for curing DDH.
