Scaphocapitate Ligament, Anterior View

Description

Oriented to the palmar aspect of the left wrist and hand, the scaphocapitate ligament is shown as a short, thick band spanning from the distal pole of the scaphoid to the palmar surface of the capitate. The ligament sits centrally in the midcarpal region, with the lunate positioned proximally and slightly ulnar to the capitate, completing the proximal carpal row relationship. Distal to the carpus, the metacarpal bases align in a gentle arc, and the thumb lies laterally (radial side) with its metacarpal angled away from the palm in keeping with normal opposition mechanics. Palmar midcarpal ligaments are often discussed abstractly, but the scaphocapitate fibers become concrete when you think about load transfer from the radial column into the central column during grip and push-off. This view supports teaching and clinical correlation for midcarpal instability patterns, where scaphoid flexion and capitate translation can accompany a dorsal intercalated segment instability (DISI) posture after scapholunate ligament injury, even when attention initially focuses on the proximal row. It also fits operative planning and arthroscopic orientation, because the palmar capsuloligamentous structures form the volar boundary encountered when assessing the midcarpal joint through standard radiocarpal and midcarpal portals. A small structure. Big consequences. Use this artwork in hand and upper-limb anatomy curricula to clarify carpal bone relationships, or in orthopedic and plastic surgery teaching files discussing scapholunate dissociation, perilunate injury patterns, and midcarpal stabilization. It also suits textbook figures and patient-facing education where you need a clean anterior map of the scaphoid, capitate, lunate, and adjacent joint lines.
