脊柱骨盆定向：对脊椎关节炎诊断的潜在影响

目标评估脊柱骨盆定向与显示新近发作炎性背痛患者可能患有axSpA的临床或影像学研究结果之间的联系。方法通过使用腰椎侧位片对骶骨水平角（40°vs≥40°），腰骶角（15°vs.≥15°）和腰椎前凸角（LL，50°vs≥50°）对最近发作的炎性背痛和疑似axSpA的DESIR队列患者的脊柱骨盆方向进行评估。使用χ2检验（或Fisher精确检验）和Mann-Whitney检验评估这些角度组与在基线期及2年后收集的变量之间的关联。使用Bonferroni校正后，P0.表明存在显着差异。结果在名患者中，名患者有有效骨水平角数值，名患者有腰骶角值，名患者有腰椎前凸角值可用；平均角度分别为39.3°，14.6°和53.0°。骶髂关节炎在腰椎前凸角50°组的X线片和MRI中显示更高患病率，但差异无统计学意义。不同角度组的临床表现和对axSpA诊断置信度没有差异。没有发现骶骨水平角，腰骶角和腰椎前凸角的退行性变化有明显差异。结论脊柱骨盆平衡与显示新近发作炎性背痛患者可能患有axSpA的临床或影像学研究结果，没有统计学关联。原文
