摘　　要：目的：探讨全髋关节置换术（ THA ）中判断假体联合前倾角的一种新方法。方法：自2010年6月～2011年6月，对126例髋关节疾病行非骨水泥型THA治疗，并应用屈髋45°时股骨头试模边缘和髋臼内衬试模边缘的关系来判断假体的联合前倾角是否在安全区，并以此来调整髋臼杯假体的前倾角。结果：术中发现用屈髋45°定位法，假体的联合前倾角全部符合Dorr的安全区标准，髋关节活动度全部能达到D＇Lima标准。结论：THA术中先安装髋臼杯假体和股骨假体试模，利用屈髋45°时股骨头试模的边缘与髋臼杯内衬试模边缘平行的方法来调整髋臼杯试模的前倾角，测试髋关节活动度，最后再依次安装假体的方法，可以使患者的髋关节达到理想的活动范围和低脱位率。Objective：To explore a new simplified method to determine combined anteversion during to-tal hip arthroplasty.Methods：From June 2010 to June 2011, 126 patients suffered from hip disease were trea-ted with cementless total hip arthroplasty , and the method of flexion 45°was used to determine whether the com-bined anterversion was within the safe zone ,and adjusted the cup anterversion according to the relationship of the edge of the femoral head and acetabular liner .Results：Using the method of flexion 45°during the operation, we found all of the combined anterversion of components were within the scope of safety which Dorr advanced , and the range of motion of the hip achieved D＇Lima standand .Conclusions：During THA operation , implanting all of the trials first, adjusting the cup anterversion according to whether the edge of femoral head and the ace -tabular liner is parallel when the hip flex 45°, then testing the range of motion of the hip , implanting the com-ponents finally , can make the patients＇hip achieve satisfied range of motion and have lowest dislocation rate .
