The dorsal carpal ligaments consist primarily of the dorsal radiocarpal, dorsal intercarpal, and dorsal ulnocarpal ligaments, forming a stabilizing network across the dorsal aspect of the wrist connecting the radius and ulna to the carpal bones. They function to maintain carpal alignment, guide coordinated wrist motion, and resist excessive flexion and translational instability. Injury or attenuation of these ligaments can contribute to carpal instability patterns, including dorsal intercalated
