Correct acetabular cup position is critical to successful total hip replacement. Unfortunately, malposition of acetabular cups is common and leads to increased rates of dislocation, wear, and ion toxicity. Despite the popularity of Lewinnek's safe zone, the exact target of acetabular abduction and version remains elusive. Differences in functional pelvic position, surgical approach, and femoral anteversion affect the optimal cup position for individual patients. Surgeons need to be aware of pelvic position changes from the supine to lateral decubitus position.
正确的髋臼杯位置对于全髋关节置换术的成功至关重要。不幸的是，髋臼杯位置不当很常见，并会导致脱位、磨损和离子毒性发生率增加。尽管Lewinnek安全区很受欢迎，但髋臼外展和前倾角的确切目标仍不明确。功能性骨盆位置、手术入路和股骨前倾角的差异会影响个体患者的最佳髋臼杯位置。外科医生需要了解从仰卧位到侧卧位时骨盆位置的变化。
