Posterior Perspective of the Dorsal Intercarpal Ligaments

Description

Positioned on the dorsum of the wrist, the dorsal intercarpal ligaments span between adjacent carpal bones across the midcarpal and intercarpal joints. Bands can be inferred bridging the scaphoid, lunate, triquetrum, trapezium, trapezoid, capitate, and hamate, running generally transverse and oblique, with fibers lying posterior (dorsal) to the joint capsules and deep to the extensor tendons. Proximally, the distal radius and ulna frame the carpus, while distally the bases of the metacarpals form the transition into the palm, keeping the ligamentous lattice centered over the carpal rows. Small joints, tight restraints. Dorsal intercarpal ligament anatomy matters because dorsal wrist pain and midcarpal instability often localize to this side of the carpus, and the dorsal capsuloligamentous complex becomes a key landmark in arthroscopic portals and dorsal approaches. Scapholunate instability and dorsal intercalated segment instability (DISI) can be understood only when you picture how dorsal restraints limit separation and abnormal rotation between scaphoid and lunate during load bearing and extension. Dorsal ganglion cysts also frequently arise near the scapholunate interval, where capsular and intercarpal fibers are stressed and may allow synovial outpouching. Educators can place this posterior perspective directly into hand and upper limb anatomy labs, orthopaedic teaching files, and radiology-pathology correlation chapters when explaining why dorsal wrist extension stresses the midcarpal joint more than most learners expect. It also suits surgical consent diagrams and technique illustrations for dorsal wrist arthroscopy, dorsal capsulotomy, and reconstruction discussions in sports medicine and hand surgery clinics.
