2、回顾2005年1月~2012年1月在我院诊断为DLs并行后路长节段脊柱融合手术治疗的63例患者。男性16例,女性47例,年龄50~72岁,平均61.4岁。根据术中DIV的选择不同分成两组,L5固定组(A组):选择L5作为DIV,共44例;骶椎固定组(B组):选择S1作为DIV,共19例。分别对两组的手术时间、出血量、固定节段数进行比较,测量并记录每例患者术前、术后末次随访的冠状面侧凸Cobb角、顶椎位移、冠状面平衡(骶骨中垂线与C7铅垂线的距离)和矢状面腰椎前凸角(T12上终板和S1上终板垂线间的夹角)、胸腰椎后凸角(T10上终板和L2下终板垂线间的
3、夹角)、矢状面平衡(C7铅垂线与S1椎体后上缘的距离)、骨盆入射角、骨盆倾斜角和骶骨倾斜角。分析两组间的并发症发生率。结果:两组间手术时间和术中出血量无显著性差异(P>0.05),但A组固定节段数平均少于B组1.36个(P=0.022);A组手术后各脊柱测量参数与术前比较均有显著性改善;B组Cobb角、顶椎位移、腰椎前凸角和胸腰椎后凸角手术前后比较有显著差异(P<0.05).但冠状面平衡和矢状面平衡则无显著差异(P>0.05);A、B两组手术前后骨盆入射角无改变(P>0.05);A组手术后骨盆倾斜角较术前显著减小(P<0.05),骶骨倾斜角则显著有增
