骨盆倾斜(PT)影响全髋关节置换术(THA)中髋臼假体的功能前倾角和倾斜度。我们回顾了138名连续接受单侧原发全髋关节置换术的患者。大多数患者术前有不同程度的PT，其中17%的患者在术前站立X线片上PT>10°。术后PT无明显变化。建立了一个半球形髋臼假体的计算机模型，将其植入骨盆内不同的解剖位置，以确定PT对功能前倾角和倾斜度的影响。根据研究结果，在大多数接受全髋关节置换术的患者中，基于站立影像的髋臼假体位置的倾斜调整可能会改善功能假体的位置。
Pelvic tilt (PT) affects the functional anteversion and inclination of acetabular components in total hip arthroplasty (THA). One-hundred and thirty-eight consecutive patients who underwent unilateral primary THA were reviewed. Most cases had some degree of pre-operative PT, with 17% having greater than 10° of PT on standing pre-operative radiographs. There was no significant change in PT following THA. A computer model of a hemispheric acetabular component implanted in a range of anatomic positions in a pelvis with varying PT was created to determine the effects of PT on functional anteversion and inclination. Based on the study results, tilt-adjustment of the acetabular component position based on standing pre-operative imaging will likely improve functional component position in most patients undergoing THA.
