The Effect of Forearm Bracing on Radioulnar Impingement

Abstract

The purpose of this clinical study was to compare patients’ symptoms and radioulnar convergence following distal radioulnar reconstruction with and without a functional brace on. Standardized radiographs were taken of the involved wrist at rest, while holding a weight, and during maximum power grip. All radiographs were then repeated while wearing a prefabricated functional brace (Maramed, Miami, FL). The functional brace did not decrease radioulnar convergence and, at rest, the brace actually increased radioulnar convergence. Despite this, all patients who experienced pain without the brace were pain free with the brace on. We conclude that forearm bracing may be a useful nonoperative treatment for residual pain following DRUJ salvage surgery, though its mechanism of action is unclear.
