Anatomical Relations

The long radiolunate ligament forms part of the palmar radiocarpal ligament. Just adjacent to the radioscaphocapitate ligament, the long radiolunate ligament arises from the palmar lip of the distal radius. It passes over the proximal part of the scaphoid to insert into the palmar surface of the lunate.

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 long radiolunate ligament supports the proximal pole of the scaphoid bone as it passes over its proximal pole to insert into the lunate (Standring, 2016).
