We report a patient with a unique complex carpal dissociation involving complete and divergent dislocation of the hamate, capitate, and trapezium with total ligamentous disruption of the distal carpal row and midcarpal joint, associated with a transverse shaft fracture of the fifth metacarpal. The mechanism of injury was a sustained torsional force resulting in a simultaneous distraction and bidirectional dorsopalmar (ulnar)-palmodorsal (radial) crushing force at the carpus.
