Abstract:
Simultaneous volar dislocations of the second through fifth carpometacarpal joints are rare injuries, usually a result of high-energy trauma to the hand. The literature regarding this topic is sparse and consists primarily of case reports. We present a case associated with median nerve contusion that was treated with open reduction and pin fixation. The median nerve injury resolved without incident, and the pins were removed at 10 weeks without loss of reduction. Three years postoperatively, the patient was without pain and had excellent use of his hand without strength or motion deficit.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
