Injuries of the carpal bones

In fractures involving the carpal bones, 80 % are fractures of the scaphoid bone and 15 % involve the triquetrum bone. Fractures of the remaining carpal bones are exceedingly rare. A prompt computed tomography (CT) scan is required for detecting not only fractures of the scaphoid bone but also other carpal bone fractures and for determining an adequate therapy. Undisplaced fractures can be successfully treated conservatively. Displaced or unstable carpal bone fractures should be operatively treated with open reduction and internal fixation, whereby bone union and restoration of range of motion and hand function can be achieved.
