摘要
目的 分析Lenke1型青少年特发性脊柱侧凸融合术中顶椎确定下固定椎的可行性.方法 82例Lenke1型患者,分为两组,按Cobb角度、Risser征、中立椎和下终椎配对.实验组以顶椎所处的节段作为依据选择下固定椎,对照组以中立椎为依据选择下固定椎.均行后路内固定和脊柱融合术,在站立位片上测量手术前后侧凸畸形矫正率和脊柱平衡;平均随访时间为3年.结果 冠状面Cobb角度和颈7距骶中线距离、矢状面胸5～胸12椎体后凸角度矫正参数差异无统计学意义.但是,对照组失平衡数较实验组多3个.结论 Lenke1型侧凸患者顶椎可以作为选择下固定椎的依据.
Objective To determine the lowest instrumented vertebra（ LIV） by apical vertebra in the spinal fusion of Lenke type 1 adolescent idiopathic scoliosis. Method Eighty-two Lenke type 1 pa- tients were divided into two groups, matched for Cobb angles, Risser sign, neutral vertebra and lower-end vertebra. In the study group, the apical vertebra was used to determine the LIV and the neutral vertebra was used in the control group. All patients received posterior internal fixation and spinal fusion. Standing radiographs were used to assess the deformity correction and spinal balance. The average follow-up was three years. Result There were no significantly differences in coronal Cobb angle, distance from the C7 line to the central sacral vertical line,and sagittal TS-T12 and plumb line deviation. But three more cases of imbalance occurred in the control group（ n = 5 ）than the study group A （n = 2）. Conclusion The apical vertebra can be used to determine the LIV in patients with Lenke type 1 adolescent idiopathic scoliosis.
