Structure

The palmar radiocarpal ligament is a strong, fibrous structure composed of multiple bundles of fibers, including the radioscaphocapitate, long and short radiolunate, and radioscapholunate ligaments. The oblique nature of the ligaments ensures that the hand follows the radius during supination of the forearm (Moore et al., 2013).

Function

The palmar radiocarpal ligament strengthens the articular capsule of the radiocarpal joint.
