Dorsal Metacarpal Ligaments, Posterior View

Description

Across the dorsum of the male hand, the dorsal metacarpal ligaments form broad fibrous bands spanning between adjacent metacarpals, reinforcing the intermetacarpal spaces from the bases toward the distal shafts. Proximally, the ligamentous fibers relate closely to the carpometacarpal region and the dorsal intercarpal and carpometacarpal capsule, while distally they approach the metacarpophalangeal joints and blend with the dorsal joint capsules. Extensor tendons course superficially in the posterior plane, with the extensor digitorum tendons aligned over the metacarpals and the extensor pollicis tendons positioned more laterally along the thumb ray. Bony landmarks remain readable beneath the connective tissue, including the metacarpal bases, shafts, and the dorsal aspects of the carpal bones. A posterior (dorsal) view is the practical angle for understanding stability at the carpometacarpal and metacarpophalangeal levels during grasp and resisted finger extension, where dorsal capsuloligamentous constraints limit pathologic translation between metacarpals. This is the anatomy you reference when assessing dorsal hand trauma, including carpometacarpal fracture-dislocations, and when planning dorsal surgical approaches that must protect extensor compartments while restoring metacarpal alignment and intermetacarpal stability. It also clarifies why dorsal swelling can mask subtle ligament injury. Small structures, big consequences. Use this plate for gross anatomy and hand surgery teaching sessions covering the metacarpus, extensor mechanism relationships, and dorsal ligamentous support, and for textbook figures discussing carpometacarpal instability patterns or dorsal approach exposures. It also fits clinical hand therapy materials that explain post-injury stiffness and the need to balance immobilization with tendon glide.
