Abstract
Untreated distal radioulnar joint (DRUJ) instability can lead to arthritis of the DRUJ. To date, however, the clinical determination of DRUJ instability still represents a challenge. We developed a new clinical test to determine its stability. This works by directly observing the ulnar head’s dynamic behavior during active pro-supination or testing the DRUJ’s static stability at different grades of rotation. With the test results, the examiner gains a better understanding of the ulna head’s behavior during rotational movements and how that compares to that of the uninjured side.
