The wrist extends anatomically and functionally from the distal forearm to the metacarpal bones and encompasses the entire carpal region. The large number of bones and joints involved are stabilized in a highly complex system of extrinsic and intrinsic ligaments, which enables a variety of different movements and stability in all positions for the best possible use of the hands. While injuries to individual ligaments or joints, most commonly the scapholunate (SL) ligament, can cause major problems the injuries associated with perilunate dislocations and dislocated fractures represent one of the greatest challenges in hand surgery.
