摘要(Abstract):
[目的]比较经皮椎体后凸成形术治疗骨质疏松压缩骨折术后骨水泥(poly methyl meth acrylate,PMMA)在椎体中的位置对疗效的影响。[方法]回顾性分析经皮椎体后凸成形术治疗骨质疏松椎体压缩骨折(单椎体)98例患者。根据术后骨水泥在椎体中的位置分为两组:侧方组(骨水泥偏于椎体一侧,未过中线)42例,中位组(骨水泥偏于椎体中央,越过中线)56例。测量并比较两组以下指标:手术前后VAS评分(10分制视觉模拟评分),ODI评分(Oswestry功能障碍指数,Oswestry disability index),SI(椎体矢状面指数,sagittal index,SI=椎体前缘高度/椎体后缘高度)及Cobb角。[结果]两组VAS、ODI评分、SI及Cobb角术前术后比较有统计学意义(P<0.05);术前及术后两组间相比,VAS、ODI评分、SI及Cobb角均无统计学意义(P>0.05);2组病例均未见患椎侧方再压缩。[结论]经皮椎体后凸成形术治疗骨质疏松椎体压缩骨折有较好的临床疗效,骨水泥在椎体中的分布位置对疗效没有显著影响,骨水泥偏一侧者不会增加椎体再次侧方压缩的风险。
