This retrospective study investigated the clinical outcomes of patients treated for chronic distal radioulnar joint instability with arthroscopic thermal annealing of the superficial radioulnar ligaments, ulnar palmar wrist ligaments, and dorsoulnar wrist capsule using a radiofrequency probe. Sixty patients (62 wrists) were treated over an 18-year period. At mean follow-up of 10 years (range 3 to 19), 30 of 33 patients were satisfied with their surgical outcomes. There were statistically significant improvements in ulnar-sided wrist pain on a visual analogue scale and in distal radioulnar joint stability on the dorsopalmar stress test after surgery compared with preoperative status. The modified Mayo Wrist Score and Quick Disabilities of the Arm, Shoulder, and Hand score of the patients were favourable. Early failure occurred in 11 of 62 wrists. Nine of these 11 wrists needed a secondary procedure. We conclude that arthroscopic thermal shrinkage is effective for the majority of the patients with mild to moderate chronic distal radioulnar joint instability in long-term follow-up. Secondary open ligament reconstruction is an option in the case of early failure. Level of evidence: IV. |
