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).
