我们对2004年4月至2011年11月期间29例强直性脊柱炎患者进行全髋关节置换术的术前评估，检查了髋臼假体与骨盆矢状解剖参数之间的相关性。4.18年未观察到假体脱位或下沉。矢状参数之间的关系符合方程：骨盆倾角(PI)=骨盆倾斜度(PT)+骶骨倾斜度(SS)。 SSNPT组取得了较好的疗效，术后功能与SS/PI呈正相关。功能性外展和前倾与PT呈正相关，但与SS呈负相关。由于AS患者骨盆和脊柱的代偿性变化，术前矢状参数的评估对于将髋臼假体放置在最佳位置以及防止术后撞击和脱位起着关键作用。 (C) 2015 Elsevier Inc. 保留所有权利。
We examined the correlation between acetabular prostheses and sagittal anatomical parameters of the pelvis for the preoperative evaluation of total hip arthroplasty in 29 patients with ankylosing spondylitis between April 2004 and November 2011. No implant dislocation or subsidence was observed at 4.18 years. The relationship between sagittal parameters conformed to the equation Pelvic incidence (PI)=Pelvic tilt (PT)+Sacral slope (SS). Better outcomes were achieved in the SSNPT group, postoperative function was positively correlated with SS/PI. Functional abduction and anteversion were positively correlated with PT but negatively correlated with SS. Due to the compensatory changes in the pelvis and spine of patients with AS, the preoperative assessment of sagittal parameters plays pivotal roles in placing acetabular prostheses in optimal positions and preventing postoperative impingement and dislocation.
