[Bipolar luxation of the 5th metacarpal bone].

A case of post-traumatic double dislocation of the fifth metacarpal is reported. No reference has been found in the literature. Both were dorsal dislocations, mechanism appears as an axial compression on the metacarpal distal extremity, as first phalanx is hyperextended. Only the carpo-metacarpal-joint was reduced by close technic with percutaneous fixation; the metacarpo-phalangeal dislocation required surgery using a palmar approach. Normal function of the joint was recovered three months later.
