The distal radioulnar joint (DRUJ) maintains the integrity of the articulation between the distal radial and ulnar regions (see Image. Wrist Ligaments). This pivot joint is critical to forearm supination, pronation, and anteroposterior translational stability. The DRUJ helps maintain the forearm ring—the region the DRUJ forms with the radius, ulna, and proximal radioulnar joint (PRUJ) essential to forearm movements and is stabilized by the interosseous membrane (IOM), annular ligament, and triangular fibrocartilage complex (TFCC). Pathologies affecting the DRUJ can impact hand, wrist, and elbow function.[1] The DRUJ is susceptible to acute injuries and chronic posttraumatic degeneration. Conditions affecting this joint can cause significant wrist pain, dysfunction, degeneration, and instability. Understanding this structure's anatomy, function, and clinical importance is crucial to managing upper limb disorders.
