BackgroundInjury to the distal radioulnar joint (DRUJ) causes swelling and ulnar-sided wrist pain. The Adams procedure stabilizes the DRUJ and shows promising short-term results.PurposeWe studied the long-term functional outcome in patients who underwent the Adams procedure. We also tested the null hypothesis that there would be no difference in range of motion (ROM) and grip strength between the operated wrist compared to the unaffected side.Patients and MethodsWe identified 74 consecutive patients that were operated from March 2005 to February 2014. Twenty-three patients responded to our invitation and underwent clinical follow-up. Three patients had a re-do of the Adams procedure after presenting with postoperative DRUJ instability, one was excluded due to additional wrist surgery not related to the initial procedure. Wrist functionality in the remaining 22 patients was examined by measuring ROM in all planes and grip strength of the operated and non-operated hand. Functional outcome was measured by asking patients to complete the Disabilities of the Arm, Shoulder, and Hand (DASH) outcome measure and the Patient-Rated Wrist and Hand Evaluation (PRWHE).ResultsAfter a mean follow-up time of 5.0 years (standard deviation [SD] 2.0), we found that supination, pronation, and grip strength were significantly decreased in the operated wrist. Postoperative DASH and PRWHE-scores averaged 13.1 (SD 18.6) and 20.3 (SD 15.1), respectively.ConclusionThe Adams procedure affects, but largely restores pronation and supination, and clinical examination, DASH, and PRWHE scores indicate that the Adams procedure leaves patients with upper extremity functionality comparable to a healthy population.Level of EvidenceLevel IV.
