Comparison of percutaneous versus open pedicle screw fixation for thoracolumbar fractures:a Meta analysis / 重庆医学

ABSTRACT

Objective To compare the feasibility and efficacy of PPSF with OPSF for thoracolumbar fractures.Methods We searched the PUBMED,OVID and Cochrane CENTRAL databases through Jan 2014.All of the clinical trials included were extrac-ted and evaluated by two reviewers independently.Data were analyzed using RevMan 5.2.6 software by the Cochrane Collabora-tion.Results Seven studies including 353 patients met the inclusion criteria.The Meta analysis found there were significant differ-ences between the two procedures in intraoperation blood loss (RR = 1.89,95%CI1.55 - 2.29,P 0.05).Conclusion Both PPSF and OPSF are safe and efficacious internal fixation methods for treating thoracolumbar fractures,while,PPSF may cause less blood loss and cost less time.
