Anatomical Relations
The radioscapholunate ligament forms part of the palmar radiocarpal ligament. It arises from the palmar lip of the distal radius, between the long and short radiolunate ligaments. It extends distally to the scaphoid and lunate bones and blends with the scapholunate interosseous ligament (Berger et al., 1991).

Function
The palmar radiocarpal ligament strengthens the articular capsule of the radiocarpal joint. The oblique nature of the ligaments ensures that the hand follows the radius during supination of the forearm (Moore et al., 2013). Additionally, the radioscapholunate ligament may be clinically important for the vascular supply of the scapholunate interosseous ligament and nervous supply (sensory) from the scapholunate articulation (Berger et al., 1991).
