A Comparison Between Volar Locking Plates and Percutaneous Pinning in the Treatment of Distal Radius Fractures: A Systematic Review

Abstract

Purpose

Percutaneous fixation with Kirschner wires and open reduction and internal fixation with volar locking plates are the most common surgical techniques for managing distal radius fractures (DRFs). As the superiority of either technique is yet to be established, we aimed to conduct an updated systematic review to compare these techniques for the optimal management of unstable DRFs.

Methods

We conducted a comprehensive literature search to identify studies comparing fixation outcomes for DRFs between groups treated with Kirschner wires and those treated with volar locking plates. Only randomized controlled trials (RCTs) were included. The revised Cochrane risk-of-bias tool was used to assess the methodological quality of RCTs. Meta-analyses were performed only on outcome measures that were reported at the same time points using the same metrics across three or more RCTs. Evaluated outcomes included the Disabilities of the Arm, Shoulder, and Hand (DASH) score, grip strength, wrist range of motion, and radiological outcomes. We also assessed the Patient-Rated Wrist Evaluation (PRWE) score and incidence of complications.

Results

Fourteen RCTs with 2,226 patients were included in the meta-analysis. DASH scores were significantly lower in the plating group at all time points. PRWE outcomes favored the plating group at follow-ups greater than 1 year. There were no significant differences in radiological outcomes or incidence of complications between the two groups.

Conclusions

Although the plating group provided marginally better functional outcomes at 1 year after surgery, the K-wire group remained a viable alternative. The reported differences should be interpreted cautiously because of the inherent variability of the included RCTs. High-quality RCTs with strict inclusion criteria and standard postoperative protocols are essential to generalize our results across all age groups and fracture types to overcome our study’s limitations.
