Outcomes After Distal Radius Fracture Treatment With Percutaneous Wire Versus Plate Fixation: Meta-Analysis of Randomized Controlled Trials
Multiple methods for surgical fixation of distal radius fractures exist, including percutaneous pinning with Kirschner wires and open reduction volar plating. Despite increased costs, the hypothesis of this study was that open reduction and volar plating does not provide improved outcomes over wire fixation. Following Transparent Reporting of Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a meta-analysis of randomized controlled trials was conducted comparing these two methods with regard to clinical outcomes, radiographic parameters, and complications. Seven trials with a total of 858 patients were included. Plating was not favored over pinning with regard to clinical outcomes and radiographic parameters. Pinning was associated with a higher superficial infection risk compared with plating, though the risk of repeat surgery was not different. It was concluded that Kirschner wire fixation, which may be associated with lower costs, is associated with similar clinical and radiographic outcomes when compared with volar plate fixation, although wire fixation is associated with higher superficial infection risk.
