title: The distal radioulnar joint.
abstract: The distal radioulnar joint (DRUJ) acts in concert with the proximal radioulnar joint to control forearm rotation. The DRUJ is stabilized by the triangular fibrocartilage complex (TFCC). This complex of fibrocartilage and ligaments support the joint through its arc of rotation, as well as provide a smooth surface for the ulnar side of the carpus. TFCC and DRUJ injuries are part of the common pattern of injuries we see with distal radius fractures. While much attention has been paid to the treatment of the distal radius fractures, many of the poor outcomes are due to untreated or unrecognized injuries to the DRUJ and its components.
