Volar fracture dislocations of the second and third carpometacarpal joints associated with acute carpal tunnel syndrome.

Volar fracture dislocation of the second and third metacarpal bases associated with acute carpal tunnel syndrome in a 17-year-old football player were treated with open reduction, via volar incision to decompress the carpal tunnel, and via a second dorsal incision for internal fixation of the fracture dislocations with Kirschner wire fixation and reinsertion of the avulsed extensor carpi radialis:longus tendon. Anatomic reduction by closed or open reduction is recommended to avoid leaving patients with a weak grip and pain over the site of the fracture.
