ABSTRACT

Carpal dislocations develop following a fall on an outstretched hand. The initial injury is a perilunate dislocation which results in a normally positioned lunate with dorsal dislocation of the remainder of the carpus. As the injury continues, there is a mixed lunate:perilunate dislocation. With more severe injury, the perilunate dislocation reduces and the lunate dislocates. Pure lunate dislocation results in volar dislocation of the lunate relative to the radius and remainder of the carpus. The AP view may be confusing, showing disruption of the carpal arcs, joint incongruity and a triangular appearing lunate. The diagnosis is establised on the lateral view. Carpo-metacarpal dislocations produce overlap of bone of this joint on the AP view and are also best seen on the lateral projection.
