Non-traumatic primary and secondary osteoarthritis of the distal radioulnar joint

Abstract

A retrospective radiographic study was conducted to determine the prevalence and severity of non-traumatic primary and secondary osteoarthritis of the distal radioulnar joint in a group of 718 patients. Non-traumatic primary and secondary osteoarthritis was found in 77 patients (11%) with a mean age of 63 years. In 34 cases it was bilateral. Mild signs of osteoarthritis were present in 53, moderate in 17 and severe in seven patients. The prevalence of primary osteoarthritis was 8.2% and 2.5% had secondary non-traumatic osteoarthritis. The prevalence and severity of the osteoarthritis were similar in women and men. Ulnar wrist pain was associated with osteoarthritis of the distal radioulnar joint in 13% of patients with mild, 35% with moderate and 43% with severe radiological degeneration. Level of evidence: IV
