摘　　要：为了防止全髋关节置换(total hip arthroplasty,THA)术后的脱位和降低假体磨损率,THA术中进行髋臼假体的定位非常重要。但由于受到多种潜在因素的影响,在手术中髋臼假体的准确植入目前仍具有一定的挑战性。Lewinnek安全区定位臼杯前倾(15±10)°,外展(40±10)°,一直被当作髋臼假体安装的标准范围,以图降低不稳定的风险。基于Lewinnek安全区,Ha提出的利用髋臼解剖标志。依据患者特异性的形态定位髋臼假体位置的方法利用患者特异性的形态确定其特异性的目标区域,从而减少髋关节置换术后的撞击,保持较低的内衬磨损率。计算机辅助导航系统可以提高髋臼杯的定位,但受到费用高,操作困难等诸多因素的影响。In order to prevent the dislocation of total hip arthroplasty（THA） and reduce the wear rate,the position of the acetabular component in THA is very important. However,due to the influence of many potential factors,the accurate implantation of the acetabular component in the operation is still a challenge. Lewinnek safety zone positioning the cup anteversion angle（15±10）°,abduction（40±10）°,has been regarded as acetabular prosthesis installation standards,in an attempt to reduce the risk of instability,but there are still reported a dislocation. Based on the Lewinnek safety zone,Ha proposed the use of acetabular anatomical landmarks. According to patient specific shape positioning the position of the acetabular component methods are used to determine the specificity of the target area,thereby reducing the impact of hip replacement,and to maintain a lower liner wear rate. Image navigation system can improve the positioning of acetabular cup,but it is affected by many factors,such as high cost,difficult operation and so on.
