Corpus: Dorsal radioulnar ligament

The dorsal radioulnar ligament extends from the dorsal aspect of the radius to the ulna and is part of the so-called TFCC (triangular fibrocartilage complex). The fibers of the dorsal radioulnar ligament, together with the fibers of the palmar radioulnar ligament, form a ring that is firmly fused with the head of the ulna and the ulnocarpal articular disc.

The dorsal radioulnar ligament tightens during pronation, contributing to its stabilization.
