Luxations carpo-métacarpiennes dorsales du quatrième et cinquième métacarpiens sans fracture

The frequency of the interesting carpometacarpal dislocation spacing is 1.93% of all injuries of the wrist and carpus. The first observations would return to Cooper and Roux in the nineteenth century. Traumatic carpometacarpal dislocations without fractures are rare. If left untreated, these lesions can lead to joint instability and early joint degeneration. We report a case of a dorsal carpometacarpal dislocation of and fourth and fifth metacarpals in a young man of 46 years, right-handed, security officer, who after a sudden nervousness lends a hand against the wall resulting in a total pain and functional impairment of his right hand. The clinical examination and radiological assessment (standard radiography and CT scan) confirm the diagnosis. We reduce its emergency dislocation by simply pulling on the axis with direct manual pressure on the bases of the metacarpals. His hand was immobilized for 6 weeks followed by rehabilitation. At 1 year follow-up, he showed no pain and returned all its activities without any discomfort.
