Multiple carpometacarpal dislocations. A case report and review of treatment.

Carpometacarpal dislocations of the ulnar four joints are rare injuries that are usually associated with high-energy trauma. Given the small number of cases reported, there exists some controversy regarding their optimal management. The case of a 27-year-old man who sustained a dorsal dislocation (without associated fractures) of the ulnar four carpometacarpal joints as a result of a fall from a height is presented. The literature regarding these hand injuries is reviewed, and the need for anatomic reduction and stabilization is discussed.
