Reconstruction of the Dorsal Ligament of the Triangular Fibrocartilage Complex

Abstract

The distal radio-ulnar ligaments (DRUL) are key components of the triangular fibrocartilage complex (TFCC). The dorsal DRUL tightens during pronation of the forearm and helps to stabilize this motion. 12 women and three men at our clinic have been treated for DRUJ instability secondary to dorsal DRUL rupture or attenuation. Their chief complaint was pain. The dorsal DRUL was reconstructed using a tendon graft, the ends of which were anchored in the bone of the radius and ulna. This technique has been shown to correct dynamic DRUJ instability in carefully selected patients, decreasing or eliminating pain and restoring normal function.
