Anatomical Relations
The ulnolunate ligament forms part of the palmar ulnocarpal ligament. It arises from the ulna indirectly via the palmar radiolunate ligament (part of the triangular fibrocartilaginous complex). The ulnolunate ligament extends distally in series with the short radiolunate ligament to insert on the palmar aspect of the lunate (Moritomo, 2013).
Related parts of the anatomy
Function
The palmar ulnocarpal ligaments strengthen the articular capsule of the radiocarpal joint and prevent displacement of the head of ulna.
