Simultaneous dislocation of the five carpometacarpal joints with concomitant fractures of the tuberosity of the trapezium and the hook of the hamate: case report.

Multiple carpometacarpal dislocations, with fractures of the trapezium and hook of the hamate carpals are rare. We report an exceedingly rare constellation of these injuries. The routine use of a carpal tunnel view is advised to identify the associated avulsion fractures with multiple carpometacarpal dislocations. We found little on this subject in existing papers. It is important because painful nonunion of avulsion fractures and compressive ulnar or median neuropathy may be ignored and thus not receive suitable treatment.
