摘要(Abstract)：

[目的]研究经椎弓根螺钉内固定选择性融合术后Lenke 1C型AIS患者矢状面参数的变化及与冠状面参数或骨盆参数之间的相关关系。[方法]选择41例连续观察的Lenke 1C型特发性脊柱侧凸患者,均行后路椎弓根螺钉固定、选择性融合术。术后随访2年。术前、术后2个月、术后2年均行站立位全脊柱正侧位X线片检查,并行影像学测量与统计。[结果]平背畸形组(胸椎后凸角<20°)患者,术后2个月(19.59±9.59)°、2年(20.45±3.59)°与术前(11.82±3.32)°比较,胸椎后凸角明显增加(P=0.010),术后2个月与2年比较,胸椎后凸角能保持稳定(P=0.998)。胸椎后凸角术后2年变化量与腰椎前凸角2年变化量、术前腰椎前凸角、骨盆投射角呈显著性相关(r值分别为-0.652,0.635,0.805,P值分别为0.041,0.049,0.005)。[结论]椎弓根螺钉内固定系统能改善平背畸形Lenke1C型患者的胸椎后凸。选择性融合术中,胸椎后凸的纠正在维持脊柱矢状位平衡中发挥重要作用。
