摘　　要：目的 :研究Salter截骨术术中定量地改变髋臼对髋臼角的影响。方法 :用多元分析方法分析髋臼前旋、ACM角 (Idelberger角 )减少及髋臼外旋与末梢骨片外移、髂骨张角和Y状软骨间距离增加的关系 ,及其对髋臼角的作用。结果 :Y状软骨间增加的距离与末梢骨片外移、髋臼前旋和外旋正相关。髂骨张角与髋臼前旋和ACM角减少正相关 ,与髋臼外旋负相关。髋臼前旋、ACM角减少和髋臼外旋对髋臼角减少作用显著 ,并且增加髋臼外旋可提高髋臼角一次改善率 ,增加髋臼前旋可提高二次矫正率。结论﨩bjective: [WT5'BZ]Our aim was to study the effect of quantitat iv ely changing the acetabulum on the acetabular angle in Salter osteotomy. [WT5'H Z]Methods: [WT5'BZ]Multiple regression analysis was used to analyse the correla tion between acetabular anterotation, decrease of ACM angle, acetabular extorsio n and external displacement of distal bone fragments, ilial opening angle,increa se of distance between Y form cartilages. [WT5'HZ]Results: [WT5'BZ]The increa sing distance between Y form cartilages had positive correlation with both exte rnal displacement of distal bone fragments and acetabular anterotation and extor sion. Ilial opening angle was positively correlative with acetabular anterotatio n but negative with acetabular extorsion. Acetabular anterotation,decrease of AC M angle, and acetabular extortion all had a significant effect on the decrease o f acetabular angle,furthermore, increase of acetabular extorsion improved primar y correction ratio, and increase of acetabular anterotation could improve the se condary correction ratio. [WT5'HZ]Conclusion: [WT5'BZ]Rotating and displacing the acetabulum quantitatively will obtain an expectant correction of acetabular angle. [WT5'HZ]
