研究背景全髋关节置换术前预测骨盆位移对准确放置髋臼假体具有重要意义.本研究旨在评估对侧关节条件对骨盆位移后THA.MethodsA的影响，共355例，进行了计算机断层扫描THA之前和之后的骨关节炎，由于发育不良进行了评估。骨盆平面基于术前和术后第1天的计算机断层扫描图像。前倾角方向的位移表示为+。对侧髋关节最小关节间隙<2 mm的受试者属于N组; ≥2 mm的受试者属于W组; THA受试者属于P组;双侧同时接受THA的受试者属于B组。在组间进行等方差检验时，使用Bartlett检验。F检验用于成对比较。结果N、W、P和B组分别有49、227、55和24例病例，位移分别为−0.2° ± 2.7°、0.8° ± 3.9°、0.5° ± 2.6°和1.1° ± 4.0°;组间差异显著（P= 0.0001）。W组与N组之间（P= .0020）、W组与P组之间（P= .0003）、P组与B组之间（P= .0086）的差异均有统计学意义。对侧关节影响骨盆移位。
BackgroundPrediction of pelvic displacement before total hip arthroplasty (THA) is important for accurate acetabular implant placement. This study aimed to evaluate the effect of contralateral joint conditions on pelvic displacement after THA.MethodsA total of 355 cases that underwent computed tomography before and after THA for osteoarthritis due to developmental dysplasia were assessed. The pelvic plane was based on preoperative and postoperative day 1 computed tomography images. The displacement in the anteversion direction was expressed as +. Subjects with a minimal joint space <2 mm in the contralateral hip joint were in group N; subjects with ≥2 mm were in group W; subjects with THA were in group P; and subjects who underwent THA simultaneously on both sides were in group B. The Bartlett test was used when conducting the equal variance test among the groups. The F test was used for pairwise comparison. APvalue <.01 was considered statistically significant.ResultsGroups N, W, P, and B had 49, 227, 55, and 24 cases, respectively, and their displacements were −0.2° ± 2.7°, 0.8° ± 3.9°, 0.5° ± 2.6°, and 1.1° ± 4.0°, respectively; the variance between the groups was significantly different (P= .0001). The differences between groups W and N (P= .0020), between groups W and P (P= .0003), and between groups P and B (P= .0086) were statistically significant.ConclusionWhen the contralateral joint space is wide, the variance of the displacement is high. The contralateral joint affects pelvic displacement.
