This case report describes specific features and difficulties about the rare carpometacarpal joint dislocation injury. The carpometacarpal joint IV seems to be the main problem in radiographic assessment because it is partially overlapped by the hook of the hamate bone. Therefore, computed tomography scans should be done in every instance especially after a closed reduction procedure. When joint transfixations become necessary, then the K-wires should not cross the midcarpal joint in order to obtain early wrist motion.
