Dorsal Radiocarpal Ligament as, Posterior View

Description

Dorsally, the dorsal radiocarpal ligament appears as a fibrous band spanning from the distal radius on the posterolateral wrist toward the dorsal surfaces of the proximal carpal row, crossing obliquely toward the scaphoid, lunate, and triquetrum. The distal ulna and ulnar styloid sit medial to the radiocarpal articulation, while the metacarpals and phalanges extend distally in line with the carpus. Extensor tendons course longitudinally over the dorsum of the wrist and hand, superficial to the carpal bones and adjacent retinacular structures, placing the ligament deep to the extensor compartments. A clean posterior relationship. This posterior perspective matters because the dorsal radiocarpal ligament is a primary restraint to palmar translation of the carpus and contributes to dorsal stability during wrist flexion and load bearing, the same mechanical context in which scapholunate and lunotriquetral patterns of carpal instability get evaluated. In dorsal wrist arthroscopy and open approaches for dorsal capsulodesis, you need a reliable sense of where the dorsal capsule thickens into the radiocarpal ligament relative to the distal radius and proximal carpal row. It also clarifies why dorsal wrist trauma can produce persistent pain even when plain radiographs look unremarkable, since dorsal capsuloligamentous injury often precedes gross malalignment. Use this artwork in gross anatomy and musculoskeletal medicine teaching to anchor dorsal wrist connective tissue anatomy, and in hand surgery or sports medicine materials discussing carpal instability, dorsal capsular injury, and operative planning around the extensor tendon compartments. It also fits radiology education when correlating dorsal ligament anatomy with MRI assessment of dorsal capsular thickening, edema, or partial tears after hyperflexion injuries.
