摘　　要：本文报告应用Ｃｈｉａｒｉ骨盆截骨术治疗髋臼发育不良、扁平髋等３６例４１个髋。３２个髋平均随防４年４个月。优良者２７个髋，占８４．３７％。术后Ｘ线片显示，截骨均获骨性愈合，髋臼对头覆盖完全，头臼相称。髋臼发育不良者，ＣＥ角平均增加２０°。作者分析此术式后认为：Ｃｈｉａｒｉ手术能增加髋臼面积，减少股骨头单位压强，截骨内移后能增加肌力臂，减少重力臂，从而减少髋关节的载荷，降低关节内压及髂骨髋内压，有利于缓解“休息痛”。为此提出成人先天性髋臼发育不良、扁平髋、股骨头无菌坏死以及髋的骨关节炎病人适合行此手术。Chiari pelvic osteotomies in 36 patients were performed.They were suffered frorn hip dysplasia,coxa plana,etc.The average following-up was four years and four months in the thirty two hips.Postoperative X-ray plates showed all the cases healed with good congruity and coverage between the acetabulum and the femoral head.The mean center-edge angle increased 20 degrees after operation.The operation could increase the contact area and thus decrease the contact pressure,intra-osseous pressure and then relieve the pain of hip.The favourable biomechanics changes after the operation were discussed in detail.Adult hip dysplasia,coxa plana,femoral head necrosis,osteoarthrosis of the hip were recommoned for this operation.
