Acetabular component orientation and position are important factors in the short- and long-term outcomes of total hip arthroplasty. Different definitions of inclination and anteversion are used in the orthopaedic literature and surgeons should be aware of these differences and understand their relationships. There is no universal safe zone. Preoperative planning should be used to determine the optimum position and orientation of the cup and assess spinopelvic characteristics to adjust cup orientation accordingly. A peripheral reaming technique leads to a more accurate restoration of the centre of rotation with less variability compared with a standard reaming technique. Several intraoperative landmarks can be used to control the version of the cup, the most commonly used and studied is the transverse acetabular ligament. The use of an inclinometer reduces the variability associated with the use of freehand or mechanical alignment guides.

初次全髋关节置换术中的杯子放置：如何在没有导航或机器人技术的情况下正确放置。

髋臼假体的方向和位置是影响全髋关节置换术短期和长期结果的重要因素。骨科文献中使用了不同的倾斜和前倾定义，外科医生应该意识到这些差异并理解它们之间的关系。没有通用的安全区。术前计划应用于确定杯子的最佳位置和方向，并评估脊柱骨盆特征以相应调整杯子方向。与标准铰孔技术相比，外围铰孔技术可以更准确地恢复旋转中心，且可变性更小。几个术中标志可用于控制杯的版本，最常用和研究的是横向髋臼韧带。
