Posttraumatic carpal and carpometacarpal dislocations represent a heterogeneous group of disorders resulting from high-energy wrist trauma. Perilunate injury is the most common and best-known manifestation of carpal dislocation, typically occurring after hyperextension trauma. Other forms are very rare and have different causative mechanisms. Carpometacarpal (CMC) dislocations are also uncommon and may affect isolated or multiple CMC joints. These lesions are prone to wrist instability if not treated promptly. The aim of this article is to provide a systematic radiologic approach to the evaluation of wrist injury and to present two acute cases of rare CMC dislocations.
