Malpositioned implants in total hip arthroplasty are associated with impingement, increased wear, and dislocations, thus precise cup positioning is crucial. However, significant deviations between targeted and actually achieved cup positions have been found even in patients operated by experienced surgeons. When aiming for higher accuracy, various methods based on freehand positioning lead by anatomic landmarks, C-arm fluoroscopy, imageless navigation, or robotic-assisted-surgery have been described. There is a constant development of new products aiming to simplify and improve intraoperative guidance. Both the literature and expert opinions on this topic are often quite controversial. This article aims to give an overview of the different methods and systems with their specific advantages and potential pitfalls while also taking a look into the future of cup positioning in anterior hip replacements.
髋关节置换术中假体位置不良与撞击、增加的磨损和脱位有关，因此精确的杯状位置至关重要。然而，即使在由经验丰富的外科医生进行手术的患者中，也发现目标杯状位置与实际达到的杯状位置之间存在显著偏差。当追求更高的准确性时，已经描述了各种基于徒手定位、解剖标志引导、C 臂透视、无图像导航或机器人辅助手术的方法。旨在简化和改进术中引导的新产品不断发展。关于这个主题的文献和专家意见往往存在很大争议。本文旨在概述不同的方法和系统及其特定的优点和潜在的陷阱，同时展望前路髋关节置换术中杯状位置的未来。
