Triquetrocapitate Ligament, Anterior View

Description

Positioned on the palmar aspect of the left wrist and proximal hand, the triquetrocapitate ligament spans from the anterior surface of the triquetrum on the ulnar side toward the capitate in the central distal carpal row. The capitate sits distal to the lunate and proximal to the base of the third metacarpal, while the triquetrum lies proximal and ulnar, adjacent to the hamate and near the pisiform. Surrounding osseous landmarks include the remaining carpal bones, metacarpals, and proximal phalanges, providing orientation for the midcarpal region. Short and taut. Palmar carpal ligaments often get overshadowed by the flexor retinaculum, yet this specific connection between the triquetrum and capitate matters when you need to explain ulnar-sided wrist pain that persists despite normal radiographs. It also helps clarify midcarpal stability concepts, where intercarpal ligament injury can contribute to subtle carpal instability patterns and altered load transfer across the ulnocarpal and midcarpal joints. For surgeons working around the proximal carpal row, this band is a practical landmark when discussing arthroscopic evaluation of intercarpal ligament integrity and the relationship of capsuloligamentous structures to the volar capsule. Use this artwork in gross anatomy and hand surgery teaching to anchor the spatial relationship of the triquetrum to the capitate, and in orthopedic or radiology publications when illustrating midcarpal ligament anatomy alongside common sources of ulnar-sided wrist symptoms. It also suits patient-facing education for explaining why a small intercarpal ligament can generate focal pain with grip and wrist deviation.
