【摘要】 目的 :研究先天性髋脱位Salter截骨术 ,Y形软骨在髋臼角矫正中的作用。方法 :分析改良Salter截骨术 5 6例、6 5髋 ,并与Pemberton截骨术 17例、18髋比较。结果 :Salter截骨术髋臼角平均矫正 16 .7° ,ACM角手术前后度数为 6 0 .0 0± 2 .18和 5 6 .40± 3.12 ,经 t检验 ,差异有高度显著性 ,P <0 .0 1。Pemberton截骨术髋臼角和ACM角平均矫正 15 .8°和 7.6°。Salter截骨术矫正的髋臼角中有 7.48°和Y形软骨成角有关。结论 :Salter截骨术中髋臼顶的髂骨部分 ,可以以Y形软骨为中心发生外倾 ,从而进一步降低髋臼角更多还原

【Abstract】 Objective: Our purpose was to study the role of Y shaped cartilage in the correction of acetabular angle of congenital dislocation of hip joint operated by using the Salter osteotomy. Methods: We analyzed 56 cases(65 hip joints) of modified Salter osteotomy of congenital dislocation of hip joint,and compared with 17 cases(18 hip joints) with Pemberton osteotomy. Results: The average correction of acetabular angle in Salter osteotomy was 16.7°.The original degrees of ACM angle before operation were 60. 00±2.18 and those of postoperation were 56.40±3.12. The P value,which was less than 0.01 in t test ,showed significant difference. In Pemberton osteotomy,the average correction of acetabular angle and ACM angle were 15.8° and 7.6°.Among the corrected acetabular angles in Salter osteotomy,there were 7.48°related with the angulation of the Y shaped cartilage.Conclusion: In Salter osteotomy, we might make the hip part of acetabular roof rotation by using the Y shaped cartilage as a center to decrease the acetabular angle.更多还原
