摘要(Abstract)：

[目的]分析后路短节段椎弓根螺钉固定联合伤椎内植骨对胸腰段爆裂骨折椎体矢状面形态变化的影响。[方法]回顾性分析2014年1月~2017年1月因胸腰段爆裂骨折在本科行后路短节段椎弓根螺钉固定+伤椎内植骨术的41例患者的临床及影像学资料,根据CT矢状面重建图像,比较分析手术前后椎体前缘高度、椎体中央高度、Cobb角的变化,同时分析椎体骨折块向椎管内压迫程度的改善情况。[结果]41例患者均顺利完成手术,椎体前缘高度由术前(53.31±9.12)%恢复至术后的(98.23±8.68)%(P<0.001),椎体中央高度由术前(64.14±8.79)%恢复至术后的(92.52±6.01)%(P<0.001),Cobb角由术前(22.92±6.88)°恢复至术后的(8.17±6.06)°(P<0.001),骨折块压迫程度由术前(31.12±11.66)%恢复至术后的(9.30±4.68)%(P<0.001),椎体前缘高度恢复量为(44.92±3.90)%,优于椎体中央高度恢复量(28.38±3.67)%(P<0.001)。[结论]后路短节段椎弓根螺钉固定联合伤椎内植骨术能有效恢复椎体前缘高度,矫正后凸畸形,并通过间接复位的方式改善椎管内压迫,但并不能完全有效恢复椎体中央高度。
