Accurate positioning of the acetabular component in total hip arthroplasty is essential to minimise the risk of dislocation and preserve the range of movement of the hip. It also affects polyethylene wear and the rate of osteolysis. Although there are many tools available to the surgeon to aid placement of the acetabular component, errors still occur, especially in version. We conducted a study of 14 cadaveric hips to investigate whether the transverse acetabular ligament can be used to align implanted cups with the correct degree of anteversion. Radiographic measurement revealed that all of the implanted cups were found to lie within the 'safe zone' for anteversion, when aligned with the ligament.
在全髋关节置换术中，髋臼组件的精确放置对于将脱位风险降至最低并保持髋关节的活动范围至关重要。它还会影响聚乙烯磨损和骨溶解率。尽管外科医生有许多工具可用于辅助髋臼组件的放置，但仍会出现误差，尤其是在角度方面。我们对14具尸体髋关节进行了一项研究，以调查髋臼横韧带是否可用于将植入的髋臼杯调整到正确的前倾角。影像学测量显示，当与韧带对齐时，所有植入的髋臼杯均位于前倾角的“安全区”内。
