Distal radioulnar joint; the articulation between the radius and ulna near the wrist.
Full Definition
The distal radioulnar joint (DRUJ) is a pivot joint formed by the articulation of the ulnar notch of the radius with the ulnar head, stabilized by the triangular fibrocartilage complex. This joint is crucial for forearm pronation and supination. DRUJ instability is a common complication of distal radius fractures and can result in chronic pain, weakness, and functional limitation. Treatment may involve ligament reconstruction or salvage procedures such as the Sauvé-Kapandji procedure.
Usage
Usage note: Always capitalize; spell out on first use in formal documents.
