Abstract
BackgroundDivergent carpometacarpal joint dislocations of the fingers are very rare. Due to severe swelling and overlapping of bones on a radiograph of the wrist and hand, dislocations are missed. The purpose of this clinical case report is to highlight this unusual injury to avoid missing diagnosis.Case presentationWe report a case of a 24-year-old Moroccan man, an athlete, who presented divergent carpometacarpal joint fracture-dislocations of the ulnar four fingers after a fall during a national cycling competition. Radiographs showed divergent dislocation and associated fractures. He underwent open reduction and fixation with percutaneous Kirschner wires followed by 6 weeks of immobilization. Active physiotherapy was started and the results were satisfactory after a 2-year follow-up.ConclusionsDivergent carpometacarpal joint dislocations of the fingers are exceptional; their diagnosis is sometimes difficult and may go unnoticed especially in a patient with polytrauma. The functional prognosis depends on the precocity of diagnosis and the quality of the reduction and rehabilitation.

The reason why dorsal dislocations are commoner is that stronger static and dynamic restraints may cause the failure of bone dorsally, with the subsequent rupture of the volar ligaments [4]
