The combined anteversion technique for acetabular component placement of total hip arthroplasty is beneficial because of the surgeons' limited ability to control the anteversion of a cementless femoral stem. Our data show that the cementless stem anteversion can be 15 degrees different than anticipated. By determining femoral stem anteversion before positioning cup anteversion, the cup anteversion can be adjusted for the stem anteversion. The combined anteversion technique should provide a mean near 35 degrees with a safe zone of 25 degrees to 50 degrees.
全髋关节置换术中髋臼组件放置的联合前倾角技术是有益的，因为外科医生控制非骨水泥型股骨柄前倾角的能力有限。我们的数据表明，非骨水泥型股骨柄的前倾角可能比预期相差15度。通过在确定髋臼杯前倾角之前确定股骨柄前倾角，可以针对股骨柄前倾角调整髋臼杯前倾角。联合前倾角技术应提供接近35度的平均值，安全范围为25度至50度。
