Description[edit | edit source]
The dorsal radioulnar ligament (DRUL) is comprised of parallel collagen bundles divides into deep and superficial limbs, which attach into the fovea and ulnar styloid respectively, spanning across the radius and ulna and forming ,among other structures, the triangular fibrocartilage complex (TFCC) located on the ulnar aspect of the wrist joint between the lunate, triquetrum, and ulnar head. [1][2]
Attachment[edit | edit source]
The DRUL is connecting the posterior margin of the ulnar notch at the distal radius to the posterior portion of the head of the ulna. The ligament innervated by the anterior and posterior interosseous nerve and the anterior interosseous artery supply her blood
function[edit | edit source]
DRUL is one of the structures enabling stabilization for the ulnar aspect of the wrist and the distal radioulnar joint (DRUJ)while also functioning as a shock absorber for the ulnar carpus. [3]
