Complications following dorsal versus volar plate fixation of distal radius fracture: a meta-analysis

Abstract

Objectives: A meta-analysis to compare complication rates following volar or dorsal surgical fixation of distal radius fracture.

Methods: A detailed search of PubMed®/MEDLINE® was undertaken to identify randomized and nonrandomized controlled trials published before 25 August 2012 that compared volar with dorsal fixation, in patients with distal radius fracture.

Results: A quantitative meta-analysis of 12 trials (952 patients) was performed. There was no between-group difference in the overall rate of complications. Volar fixation was associated with significant increases in neuropathy (relative risk [RR] 2.19; 95% confidence intervals [CI] 1.27, 3.76) and carpal tunnel syndrome (RR 4.56; 95% CI 1.02, 20.44), and a reduction in tendon irritation, compared with the dorsal approach (RR 0.38; 95% CI 0.17, 0.86).

Conclusions: Dorsal fixation offers a lower risk of neuropathy and carpal tunnel syndrome than the volar approach, but a higher risk of tendon irritation. Patients with a distal radius fracture can expect similar outcomes after volar or dorsal surgery.
