Scapholunate Instability of the Wrist following Distal Radius Fracture

Fractures of the distal radius are no longer frequent only in elderly women, as has recently been common, but they are found more and more often in active young persons. Because their bones are healthier, soft tissues are affected more frequently. Injury to the SL joint results in the development of arthritic lesions which may rapidly progress in active patients. SLAC development can be prevented by early diagnosis of soft tissue lesions on X-ray images, because these are usually apparent after reduction or at follow-up. If doubts arise, arthroscopy or another examination should be done, even though these may not be sufficiently reliable.
