摘要 [目的]探讨影响Lenke 1型青少年特发性脊柱侧凸(adolescent idiopathic scoliosis,AIS)患者术后顶椎区残留旋转的危险因素。[方法]选取2010年1月~2014年10月在本院行后路融合术的26例Lenke 1型AIS患者,其中男5例,女21例。按照术后顶椎区残留旋转的严重程度将AIS患者分为两组:A组(顶椎区椎体残留旋转比率〈70%)15例,B组(顶椎区椎体残留旋转比率〉70%)11例。分析两组患者的性别、年龄、Risser征、术前主胸弯Cobb角、主胸弯柔韧度、术前顶椎区椎体旋转角度、术前及术后的顶椎偏移距离和躯干偏移距离、胸椎矢状位Cobb角改善率、主胸弯矫正率以及顶椎区置钉密度。单因素分析对比两组患者在上述指标的差异性,并进行Logistic多因素回归分析。[结果]两组间患者的主胸弯柔韧度、术前顶椎偏移距离、主胸弯矫正率、顶椎区置钉密度差异具有统计学意义(P〈0.05);多因素回归分析显示导致术后顶椎区残留旋转的独立危险因素包括主胸弯矫正率、顶椎区置钉密度(P〈0.05)。[结论]Lenke 1型AIS患者主胸弯矫正率、顶椎区置钉密度是影响术后顶椎区残留旋转的危险因素。
