Abstract
Introduction
Distal radius fractures are common and trends for fixation have changed with increased use of volar locking plates in recent time. A meta-analysis will summarise the best evidence for treatment.
Method
A systematic review was conducted using PRISMA methodology to identify studies that reported clinical and/or radiological outcomes in patients with AO type C distal radius fractures when treated with external fixation versus ORIF.
Results
10 randomised trials were included in this review, reporting on 967 patients. Clinical outcomes are in favour of volar plating at 3 months post-operation, but no difference between the two groups is seen at 6 or 12 months. Analysis of complication rates shows a minute increase in risk-ratio for volar plating versus external fixation. Subgroup analysis showed significantly higher re-operations after plate fixation and significantly higher infection after external fixation.
Conclusions
Internal fixation of complex distal radius fractures confers an improved clinical outcome at early follow up only and a minimally increased risk of complications. The improved grip strength with volar plating is only superior at early follow up and no long-term superiority is seen with either intervention. The type of surgery in this injury type therefore remains at the surgeon’s consideration on a case-by-case basis.
