Abstract
The purpose of this study was to evaluate forearm rotation after volar plating of the distal radius fractures with and without pronator quadratus repair. This was an institutional review board-approved retrospective review of prospectively collected data. The study was conducted at an Academic Medical Center. Over a 5-year period, 606 patients with distal radius fractures (OTA classifications 23-A through 23-C) were enrolled in an institutional review board-approved, prospectively collected, distal radius database. One hundred and seventy-five patients underwent open reduction and internal fixation with volar plating. Of these, 112 patients had complete 1-year follow-up (6 weeks, 3, 6, and 12 months) and were included in this study. Volar plating of the distal radius was performed with pronator quadratus repair (group A), versus volar plating without pronator quadratus repair (group B). Surgeries in group A were performed by a fellowship trained hand surgeon utilizing volar plates from Depuy Orthopedics (Warsaw, IN), whereas the surgeries in group B were performed by a fellowship trained orthopedic trauma surgeon utilizing volar plates from Stryker (Mahwah, NJ). Primary outcomes include forearm range of motion. Secondary outcomes include grip strength, pain levels, functional outcomes (DASH scores), radiographs, and complications. Baseline and demographic characteristics of the patients were similar between the 2 groups. There was no difference in mean pronation (P = 0.08) at 1 year. Among secondary analyses, radial deviation was significantly different (P = 0.03); however, pain (P = 0.13) and DASH scores (P = 0.14) were not. The only patient that requested plate removal had the pronator repaired (group A). We conclude that there is no advantage in repairing the pronator quadratus during volar plating of distal radius fractures. Therapeutic Level III.
