Complications Following Volar Locking Plate Fixation of Distal Radius Fractures in Adults: A Systematic Review of Randomized Control Trials

Abstract

The purpose of this study was to assess the incidence of postoperative complications following volar locking plate (VLP) fixation of distal radius fractures (DRFs). A search using keywords and subject headings to represent the concepts of volar plating and radius fractures was generated. Databases such as MEDLINE (Ovid), Embase (Elsevier), Scopus (Elsevier), and SPORTDiscus (EBSCO) were searched from inception to November 24, 2021, for randomized controlled trials that reported complications following DRF treated with VLP. Inclusion criteria were studies with adult patients (aged ≥18 years) randomized to VLP fixation without other concomitant surgical interventions, with a minimum follow-up of 3 months. Study sample characteristics and post-surgical complications were extracted. The Cochrane Risk of Bias tool was used to evaluate quality of evidence. Of the 4,059 articles identified using the search strategy, 1,778 titles/abstracts and 856 full-text articles were screened for inclusion, of which 35 articles were included for data extraction. Overall, 1,419 patients with a DRF were randomized to VLP fixation. The mean age was 60.3 years. The overall complication rate was 30.8% following VLP fixation, with 12.4% being major complications. The most common complications were median nerve-related (7.1%) and hardware removal (6.8%), secondary to other complications. Tenosynovitis was the most common tendon-related complication (3.4%). Other complications included complex regional pain syndrome (2.4%), malunion (1.3%), superficial wound infections (1.9%), and tendon rupture (1.3%). A meta-analysis of high-quality studies that discuss the complications after VLP fixation for DRF showed an overall complication rate of 30.8%. VLP may be related to more hardware-related complications than those previously reported. Therapeutic II.
