摘要(Abstract)：

[目的]探讨青少年特发性脊柱侧凸(adolescent idiopathic scoliosis,AIS)Lenke1B、C患者的胸椎矢状面形态(thoracic kyphsis,TK)对腰骶椎矢状面形态的影响及意义。[方法]86例Lenke1B、C患者(男37例、女49例;平均年龄14.2岁)被纳入本研究,所有患者均摄站立位全脊柱正侧位X线片。根据胸椎后凸(TK)分为两组:A型TK<10°和B型10°≤TK≤40°。统计、测量以下影像学参数:腰椎前凸(LL)、上腰椎前凸、下腰椎前凸、主胸弯Cobb角、矢状面平衡(SVA)、骨盆投射角(PI)、骶骨倾斜角(SS)和骨盆倾斜角(PT)。[结果]A型的LL和上腰椎前凸小于B型的LL和上腰椎前凸(P<0.01)。相关性结果显示TK与LL(r=0.68,P=0.02)、上腰椎前凸(r=0.89,P=0.003)存在线性相关。此外,PT、SS及PI之间也存在线性相关。[结论]AIS Lenke1B、C患者的胸椎矢状面形态对腰椎前凸有明显影响,并通过上腰椎对整个腰椎形态产生影响。因此,对此类型患者在进行选择性胸椎融合时必须考虑这种相互影响,避免术后发生远端失代偿。
