title: Radioulnar ratio in detection of distal radioulnar joint instability associated with acute distal radius fractures.
abstract: Lesions of the triangular fibrocartilage complex (TFCC) are commonly associated with distal radius fractures and may adversely affect the functional outcome. This prospective study evaluated computed tomography, using the radioulnar ratio (RUR), to detect laxity of the distal radioulnar joint in 48 consecutive patients with acute distal radius fractures and compared the results with a radioulnar stress test. We found the clinical stress test to be reliable in chronic cases, but the RUR method of questionable value in both acute and chronic cases.
