Modified brachioradialis wrap for stabilizing the distal radioulnar joint: case report

Distal radioulnar joint (DRUJ) stability requires competent static and dynamic soft tissues. Multiple DRUJ techniques have been described in the literature. Our method is a novel modification of the Gupta method of DRUJ stabilization used in a revision reconstruction on a patient with a total wrist arthroplasty. A brachioradialis graft is harvested and tunneled through Parona’s space volar to the pronator quadratus and through the muscle body. The tendon is then brought dorsal between the radius and ulna to the dorsal side of the distal ulna and sutured to the floor of the 5th extensor compartment, as well as to the surrounding extensor reticulum ulnar to the 6th compartment with nonabsorbable sutures. Our modification of the method described by Gupta prevents ulnar subluxaton of the extensor carpal ulnaris (ECU), allows the tendon graft construct to more adequately resist volar translation of the radius, and thus acts like a leash to pull the radius dorsally to the stationary ulna. This modification gives the graft a better force vector to resist the volar translation of the distal radius. We are able to present successful 30-month follow-up of this procedure.
