摘要(Abstract)：

[目的]通过影像学测量脊柱高度和胸廓容积变化,评估生长棒技术治疗先天性脊柱侧凸对胸廓发育的影响。[方法]分析2010年7月~2016年7月本院23例应用生长棒技术治疗的先天性脊柱侧凸患儿的完整资料,测量术前、初次及各次撑开术后和末次随访时脊柱全长正侧位X线片脊柱和胸廓发育相关参数指标,包括主胸弯Cobb角、T_1~T_(12)高度、胸椎后凸角度、胸廓前后径和矢状纵径、胸廓最大宽度、坎贝尔空间供肺比值,并进行统计学分析。[结果]初次及各次撑开术后和末次随访时,主胸弯Cobb角、TK、T_1~T_(12)高度、胸廓最大宽度、胸廓前后径和矢状纵径以及SAL均较术前差异有统计学意义(P<0.05);术前到末次随访主胸弯Cobb角变化值与T_1~T_(12)高度(r=0.584,P<0.05)、胸廓矢状高度(r=.0594,P<0.05)及SAL的变化值间(r=0.693,P<0.05)呈正相关;随撑开次数增加,各项胸廓发育参数变化曲线先显著增加后逐渐趋于平缓。[结论]利用生长棒技术治疗先天性脊柱侧凸,不仅能够矫正脊柱畸形、保留脊柱生长潜能,还可以调整左右胸廓的高度差和不对称性,增加胸廓容积容量,但随着撑开次数增加,这种效应逐渐趋于减弱。
