Aiming for a combined cup and stem anteversion within a target range is one way to assess appropriate prosthetic component orientation and restoration of functional range of motion. We describe a surgical technique that allows the surgeon to assess the combined anteversion using a handheld accelerometer-based navigation system for total hip arthroplasty through a posterior approach. The femur is prepared first, at which time the femoral version is estimated by the surgeon. The acetabular component is then positioned using the navigation system to estimate anteversion, with the goal of providing a combined version of 37° ± 7°. The described technique allows surgeons to achieve the desired intraoperative combined anteversion.

将髋臼杯和股骨柄的联合前倾角设定在目标范围内是评估假体组件正确定向以及恢复功能活动范围的一种方法。我们描述了一种手术技术，该技术允许外科医生通过后路全髋关节置换术，使用基于手持加速度计的导航系统来评估联合前倾角。首先准备股骨，此时由外科医生估计股骨前倾角。然后使用导航系统定位髋臼组件以估计前倾角，目标是提供37°±7°的联合前倾角。所描述的技术使外科医生能够在术中实现所需的联合前倾角。
