Trapezo-metacarpal and metacarpo-phalangeal dislocation of the thumb associated with a carpo-metacarpal dislocation of the four fingers.

The authors report a case of combined dorsal fracture-dislocations of all 4 fingers, palmar trapezo-metacarpal dislocation and metacarpophalangeal dislocation of the thumb following a motorbike accident. These exceptional lesions were treated as an emergency by reduction and pinning. With a follow-up of 13 years, the patient still worked as an electrician.
