The Influence of Articular Morphology on Non-Traumatic Degenerative Changes of the Distal Radioulnar Joint. A Radiographic StudyFrom the Department of Orthopaedic Surgery, Ghent University Hospital, Belgium Correspondence: Dr Nadine Hollevoet, Department of Orthopaedic Surgery, Ghent University Hospital, De Pintelaan 185, B9000 Gent, Belgium., Tel.: +32 92403933; fax: +32 92404975. E-mail: nadine.hollevoet{at}ugent.be We examined 248 wrist X-rays of patients over 50 years of age to find out if ulnar variance, orientation of the sigmoid notch and ulnar head inclination play a role in the development of non-traumatic osteoarthritis of the distal radioulnar joint. Minor degenerative changes, viz. focal joint space narrowing and/or lipping, or small osteophytes at the inferior edge of the ulnar head, were present in 13% of the X-rays of these wrists. They were significantly more frequent in wrists with a more inclined ulnar head and significantly less present in wrists with an oblique, distally orientated sigmoid notch. There was no significant association with ulnar variance or age. This study suggests that articular morphology may play a role in the development of degenerative changes of the distal radioulnar joint.
