Radioulnar laxity and clinical outcome do not correlate after a distal radius fracture.

Injury to the triangular fibrocartilage complex associated with distal radius fracture may cause symptoms of ulnar instability. Assessed by a radioulnar stress test, increased laxity of the distal radioulnar joint has in two previous studies been depicted to be associated with poorer outcome. This prospective study of 40 adults investigates the correlation of this test with functional outcome as measured by DASH. No clinically significant difference was found in relation to this test at two and five years after injury. Therefore using this test alone to decide whether or not to perform an acute repair of the TFCC cannot be recommended.
