Abstract
Carpo-metacarpal dislocations are rare traumatic injuries resulting from violent trauma; they are mostly observed in young subjects. The spatular form is often accompanied by metacarpal fractures. We report a clinical case of complete dorsal carpo-metacarpal spatular dislocation. This was a 34-year-old patient, admitted for a closed trauma of the right hand, in whom the clinical examination noted edema of the hand. The radiological workup showed a complete dorsal spatular dislocation associated with a fracture of the base of the 2nd metacarpal. The reduction of these lesions in closed focus followed by stabilization by metacarpal broaching associated with an intermetacarpal transverse broach was done under scopic control in emergency. Functional rehabilitation was started in the 3rd week. The broaches were ablated at the 6th week. The functional result at 3 months was satisfying with good muscle strength. Resumption of work was effective at 8 weeks. Carpo-metacarpal dislocations are rare injuries, often unrecognized, especially in polytrauma patients, and have a good functional prognosis if they are managed correctly in an emergency.

Summary
Carpo-metacarpal dislocations are rare, especially in the four long fingers [1]. Complete spatular dislocations are more often dorsal than palmar or divergent; they are often accompanied by metacarpal. Their diagnosis is radio clinical: X-ray of the wrist, face and strict profile; as an X-ray of the face and 3/4 hand to look for associated lesions in the hand. We report the case of a 34-year-old patient who presented with a dorsal complete spatular fracture-dislocation following a traffic accident. He was managed in the trauma emergency room
