Carpometacarpal (CMC) dislocations without associated fractures of the adjacent bones are extremely infrequent injuries. Dorsal or volar dislocations occur after high-energy injuries and may lead to early post-traumatic arthritis and carpal instability. The purpose of this study was to present a case of dorsal dislocation of both the fourth and fifth CMC joints that were treated with closed reduction and casting. A 31-year-old man developed severe acute pain, functional limitation, and deformity of the wrist after falling from a height. The clinical examination revealed intense localized tenderness, swelling, and palpable prominence over the fourth and fifth metacarpals. Standard anteroposterior and lateral views demonstrated dislocations of the examined CMC joints without any accompanied fracture. The injury was treated with anatomic closed reduction and cast immobilization for overall five weeks followed by early mobilization. Twelve weeks after injury, the patient had regained grip strength, and six months post-traumatically he satisfactorily returned to his previous hard labor-intensive activities without any functional deficits or chronic pain. Conclusively, CMC dislocations can be treated conservatively in case of early diagnosis and stable anatomic closed reduction.
