背景;对矢状面平衡参数的早期研究大多未考虑脊肌对脊柱排列的影响。目的:分析老年患者椎旁肌(数量和质量)和矢状位形态的关系。方法:回顾性分析50例老年人脊柱侧位X线和腰椎磁共振图像。影像学参数是胸椎后凸畸形,腰椎前凸(LL),矢状面平衡,骨盆倾斜角,骶骨倾斜角及骨盆投射角(PI)。磁共振图像观察患者L3水平椎旁肌腰部肌肉发达(LM;数量)程度及脂肪变性率(FD;质量)。应用Pearson相关系数和多

背景;对矢状面平衡参数的早期研究大多未考虑脊肌对脊柱排列的影响。

目的:分析老年患者椎旁肌(数量和质量)和矢状位形态的关系。

方法:回顾性分析50例老年人脊柱侧位X线和腰椎磁共振图像。影像学参数是胸椎后凸畸形,腰椎前凸(LL),矢状面平衡,骨盆倾斜角,骶骨倾斜角及骨盆投射角(PI)。磁共振图像观察患者L3水平椎旁肌腰部肌肉发达(LM;数量)程度及脂肪变性率(FD;质量)。应用Pearson相关系数和多元线性回归分析相关参数与LM和FD之间的关系。

结果:Pearson分析表明,FD与年龄(r = 0.393)胸椎后凸(R =−0.559),骨盆倾斜角(R = 0.430),矢状面平衡(R = 0.488)和PI−LL(r = 0.479,P<0.05)存在显著相关性,且发现FD和LL存在负相关(r =−0.505,P<0.01)。LM 与LL(r = 0.342)和PI−LL(R =−0.283,P<0.05)有显著相关性。校正混杂因素如体重指数后,回归模型也证实上述参数与FD的相关性(P<0.05)。

结论:椎旁肌的质量可能是影响矢状面平衡的重要因素之一。
