RECONSTRUCTION OF THE DORSAL LIGAMENT OF THE TRIANGULAR FIBROCARTILAGE COMPLEX

The distal radio-ulnar ligaments (DRUL) are key components of the tria ngular 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 sec ondary to dorsal DRUL rupture or attenuation. Their chief complaint wa s pain. The dorsal DRUL was reconstructed using a tendon graft, the en ds of which were anchored in the bone of the radius and ulna. This tec hnique has been shown to correct dynamic DRUJ instability in carefully selected patients, decreasing or eliminating pain and restoring norma l function.
