Abstract: Disclosed is a brace for treating an injury of the distal radio-ulna joint of an individual. The brace may include a semi-rigid support member having a concave surface configured to extend longitudinally over a distal radius of the individual adjacent the individual's distal radio-ulna joint, and at least one retaining arm configured to be wound about the individual's arm to engage with an outer surface of the support member. The at least one retaining arm is formed from a resilient material such that tightening of the retaining arm about the individual's arm applies pressure to the distal radio-ulnar joint to alleviate pain and discomfort experienced therein.
