全髋关节置换术（THA）是最常见和最成功的外科手术之一。最常用系统的 10 年存活率超过 95%。然而，在干预后的 0-1 年内，翻修的发生率通常要高得多。在此早期时期进行翻修的最常见原因是脱位和半脱位，这可以分别定义为轴承表面之间完全或永久、以及部分或暂时失去接触。这项研究包括开发骨骼几何模型和原位全髋关节置换术，以预测各种髋臼杯位置以及一系列经常进行的日常生活活动的骨骼和部件撞击的发生和位置。开发的模型预测前上部件撞击与导致后脱位的活动有关。增加罩杯前倾角和倾斜度可降低发生率。后下部组件撞击与前脱位活动相关。其发生率可通过降低罩杯前倾角和倾斜度来降低。确定了组件无碰撞范围，从杯子以 45° 倾斜和 25° 前倾定位到 70° 倾斜和 15°–20° 前倾定位。
Total Hip Arthroplasty (THA) is one of the most common and successful surgical interventions. The survivorship at 10 years for the most commonly used systems is over 95%. However, the incidence of revision is usually much higher in the 0–1 year time period following the intervention. The most common reason for revision in this early time period is dislocation and subluxation, which may be defined as complete or permanent, and partial or temporary loss of contact between the bearing surfaces respectively. This study comprises the development of a geometric model of bone and an in situ total hip replacement, to predict the occurrence and location of bone and component impingement for a wide range of acetabular cup positions and for a series of frequently practiced activities of daily living. The model developed predicts that anterior-superior component impingement is associated with activities that result in posterior dislocation. The incidence may be reduced by increased cup anteversion and inclination. Posterior-inferior component impingement is associated with anterior dislocation activities. Its incidence may be reduced by decreased cup anteversion and inclination. A component impingement-free range was identified, running from when the cup was positioned with 45° inclination and 25° anteversion to 70° inclination and 15°–20° anteversion.
