Dorsal Ulnocarpal Ligament, Anterior View

Description

Prominent in the proximal hand and wrist, the dorsal ulnocarpal ligament is rendered as a stout ligamentous band arising from the distal ulna and coursing distally toward the ulnar-sided carpal row, with its fibers spanning toward the triquetrum and adjacent ulnocarpal capsule. Deep to it lie the distal radioulnar joint region and ulnar head, while the carpal bones sit distal to the ulna and the metacarpals and phalanges extend further distally in anatomical position. Articular cartilage is indicated at the radiocarpal, intercarpal, metacarpophalangeal, and interphalangeal joints, framing how the ligament relates to the ulnar carpus rather than the digital rays. Bony landmarks matter here. Ulnar-sided wrist pain often comes down to the triangular fibrocartilage complex (TFCC), and the dorsal ulnocarpal ligament is one of the stabilizing components that helps resist abnormal translation between the distal ulna and the proximal carpal row during pronation-supination and ulnar deviation. This anteriorly presented, dorsal-structure emphasis clarifies why tears near the ulnar fovea or styloid attachments can destabilize the distal radioulnar joint and coexist with ulnocarpal impaction, even when plain radiographs look unrevealing. Surgeons and imagers both track these fibers when correlating arthroscopy with MRI. Ideal for anatomy teaching in hand and upper limb modules, this figure also supports orthopedic or sports medicine content on TFCC injury patterns, distal radioulnar joint instability, and wrist arthroscopy portals and landmarks. It fits cleanly into operative manuals, rehabilitation protocols discussing ulnar-sided wrist sprain, and patient-facing education where you need clear separation of ulna, carpus, and joint cartilage surfaces.
