联合骨折椎体置钉与短节段椎弓根螺钉内固定治疗胸腰椎单个椎体骨折的Meta分析

Injured vertebra pedicle screw fixation versus short-segment pedicle instrumentation for thoracolumbar fracture: a meta-analysis

背景:后路内固定术是治疗脊柱胸腰椎骨折的常用方式之一,对于联合骨折椎体椎弓根螺钉内固定与短节段椎弓根螺钉内固定的疗效仍缺乏系统评价。目的:系统评价联合骨折椎体椎弓根螺钉内固定与短节段椎弓根螺钉内固定治疗胸腰椎单个椎体骨折的疗效差异。方法:计算机检索1990至2016年Pubmed、Medline、Embase、Cochrane library、中国知网、维普、万方、中国生物医药电子数据库电子数据库,查找对比椎弓根螺钉内固定治疗胸腰椎骨折时骨折椎体置钉与否的临床随机对照试验研究或队列研究,制定严格的纳入和排除标准,采用Revman 5.3软件进行Meta分析。结果与结论:(1)纳入文献11篇,其中5篇英文,6篇中文,共纳入689例患者,其中联合骨折椎体椎弓根螺钉内固定术治疗328例,短节段椎弓根螺钉内固定术治疗361例;(2)Meta分析结果显示,2种手术方式在手术时间、出血量及平均住院时间上差异无显著性意义;对于改善后凸畸形及恢复骨折椎体前缘高度上,联合骨折椎体置钉组术后和1-5年随访效果均优于短节段椎弓根螺钉内固定组;而且骨折椎体置钉组术后内固定失败率明显少于短节段固定组;(3)结果表明,在术后及1-5年的随访中,联合骨折椎体椎弓根螺钉内固定在改善后凸角、恢复椎体前缘高度及减少术后内固定失败发生率方面均优于短节段椎弓根螺钉内固定。

BACKGROUND： Posterior internal fixation is one of the most common methods for thoracolumbar fractures. There is a lack of systematic evaluation about the efficacy of injured vertebra pedicle screw fixation（IVPSF）versus short-segment pedicle instrumentation （SSPI） for thoracolumbar fracture. OBJECTIVE： To compare the clinical outcomes of IVPSF and SSPI for single thoracolumbar fracture through a METHODS： A computer-based on-line research of PubMed, Medline, Embase, Cochrane Library, CNKI, and WanFang databases was performed for the studies regarding IVPSF versus SSPI for thoracolumbar fracture from 1990 to 2016. meta-analysis. The randomized controlled trials and cohort studies were collected based on the strict criteria of inclusion and exclusion. A meta-analysis was conducted on Revman5.3 sofeware. RESULTS AND CONCLUSION： （1） Eleven articles were enrolled, including 5 English and 6 Chinese ones, involving 689 patients （328 cases for IVPSF and 361 cases for SSPI）. （2） The meta-analysis indicated that the operation time, blood loss and mean hospital stay showed no significant differences between two groups. IVPSF showed more effective than SSPI in the kyphotic angle correction and anterior vertebral height recovery at postoperation and 1-5 years of follow-up. Moreover, the incidence of postoperative fixation failure in IVPSF was lower than that in SSPI. （3） These findings suggest that IVPSF that reduces the postoperative fixation failure rate for thoracolumbar fractures provides better kyphosis correction and restoration of anterior vertebral height at post-operation and 1-5 years of follow-up.
