Chronic post-traumatic dynamic distal radioulnar joint instability following rupture of the distal radioulnar ligaments may cause disabling and progressive ulnar-sided wrist symptoms. We use a free tendon graft to anatomically reconstruct both dorsal and palmar distal radioulnar ligaments simultaneously. Nine patients who underwent this procedure between 1990 and 1997 were assessed using a modified Mayo Wrist Score. Following surgery, average wrist scores improved from 66 (95% CI, ±3.0) to 92 (95% CI, 92±6.9) and were maintained in the long term (average score, 87 at 9 years). Joint stability was restored and maintained in seven of the nine patients, but two developed recurrent instability. Pain, grip strength and function were better following surgery in the short and long term. Range of supination and pronation decreased slightly from an average of 169° pre-operatively to 155° (90% of normal) in the long term. Long-term radiographs show no distal radioulnar or ulnocarpal joint osteoarthritis.

Key Words: distal radioulnar joint • ligament reconstruction
