BERLIN — Ulnar head arthroplasty was associated with pain relief and greater function in patients with various pathologies for which the procedure is indicated, including distal radioulnar joint disorders, according to data presented, here.

“Ulnar head replacement is a successful procedure in relieving pain in distal radial arm joint disorders regardless of etiology and successful functional outcomes can be achieved in patients treated with distal radial ulnar joint osteoarthritis and previous traumatic injuries,” Benjamin D. Chatterton, an undergraduate at the Department of Trauma & Orthopaedics, Brighton & Sussex University Hospitals in the United Kingdom, said in his presentation at the 13th EFORT Congress 2012.

Mean scores with a modified version of the DASH score, called the QuickDASH score, were 40.05 ± 18.72 points, the investigators reported. However, the best results were in patients who had osteoarthritis that stemmed from a distal radioulnar joint (DRUJ) disorder, where the mean scores were 29.83 ± 18.77 points, according to the abstract.

There was a significant decrease in pain based on the mean preoperative Visual Analog Scale score of 8.29 ± 1.52, which changed to a mean postoperative score of 3.19 ± 2.20.

Of patients who underwent the procedure, 8 patients had osteoarthritis. Six patients were diagnosed with inflammatory arthritides and 3 patients had post-traumatic DRUJ dysfunction, according to the abstract. Three procedures were revision procedures, and the indication for surgery was unknown in one patient.
