1、提要目的:观察单侧和双侧椎弓根螺钉固定加椎间植骨融合治疗腰椎退行性疾病的临床疗效,分析腰椎单侧椎弓根螺钉固定加椎间植骨融合的生物力学稳定性。方法:对2009年3月到2011年10月病房收治的68例具有完整资料的腰椎退行性疾病患者进行回顾性分析,其中32例减压后采用单侧椎弓根钉内固定,36例减压后采用双侧椎弓根钉内固定,所有病例均同时行椎间植骨融合。比较两组手术时间、术中出血量,并根据VAS评分和JOA(日本骨科协会评估治疗分数)评分评估治疗前后腰椎功能改善情况,计算改善率,随访观察植骨融合情况。结果:比较两组的手术时间和出血量,单侧组少于双侧组,差别有统计学意义(P<0.05)。术
2、后68例获得3~9个月随访,平均6个月,随访期间均未发现Cage移位或下沉、椎弓根螺钉松动断裂。VAS评分和JOA评分同组术前术后比较有显著性差异(P<0.01)。结论:单侧与双侧椎弓根螺钉固定加椎间植骨融合都能使腰椎获得可靠的稳定性,与后者比较,前者手术方法简单,并且可缩短手术时间,减少出血量,减少并发症。关键词单侧固定腰椎融合腰椎退行性疾病生物力学Clinicalstudyofunilateralandbilateralpediclescrewfixationwithintervertebralbodyfusionintreatinglumbardegenerativedise
