Outcomes of Arthroscopic-Assisted Distal Radius Fracture Volar Plating: A Meta-Analysis

Abstract

Purpose: The use of wrist arthroscopy to assist fixation of distal radius fractures with volar locking plates (VLPs) has been gaining popularity in recent years; however, there is no consensus on its benefits. This meta-analysis compares outcomes of arthroscopic-assisted VLP to fluoroscopic-assisted VLP in distal radius fractures through a systematic review of the published literature. Methods: A systematic search of publications from databases (Medline, EMBASE, Scopus, and Cochrane) was obtained from inception to May 2020. A random-effects meta-analysis was used to calculate effect sizes. Outcomes included postoperative radiographic reduction (gap, stepoff, radial inclination, volar tilt, and ulnar variance), procedural outcomes (operative time, additional soft tissue injuries and complications), and functional outcomes (range of motion; visual analog scale score; Disabilities of the Arm, Shoulder, and Hand score; Patient-Rated Wrist Evaluation score; Mayo clinic score; and grip strength). Results: Six studies, involving 280 patients, met the final inclusion criteria. The meta-analysis for postoperative stepoff was statistically significant, favoring arthroscopic-assisted VLP. In addition, there was greater identification of associated soft tissue injuries, increased wrist extension, and a longer operative duration when performing arthroscopic-assisted VLP fixation. There were no differences in other postoperative radiographic outcomes, complications, or functional outcomes. Conclusions: The current literature suggests that arthroscopic-assisted VLP is a useful adjunct to intra-articular reduction and treatment of associated soft tissue injuries in distal radius fractures. Considerations should include operative time, costs, and the additional training required. Further studies are needed to assess functional outcomes.
