RESUMO
BACKGROUND: Carpometacarpal joint fracture dislocation of the second to fifth finger is a rare hand injury associated with high energy trauma. Due to severe swelling and overlapping of bones on the radiograph of wrist-hand, dislocations are missed. We reported a series of six patients with rare carpometacarpal joint fracture dislocation treated with open reduction. METHODS: We retrospectively studied six cases of carpometacarpal joint fracture dislocation. All patients were treated with open reduction and internal fixation with Kirschner wire. Functional assessment was done with Quick Disabilities of the Arm, Shoulder and Hand score (Quick DASH score) at regular intervals. RESULTS: Average Quick DASH score was improved from 75.76 to 1.9 from 6 weeks to 18 months of duration. Of the six patients, three patients had a Quick DASH score of 0 at the end of 18 months. CONCLUSIONS: Careful hand examination and radiographic assessment is necessary to avoid missed diagnosis of carpometacarpal joint fracture dislocation. Early open reduction and internal fixation lead to excellent recovery of hand function.

There are variable types in wrist joint injury. Most common case is simple distal radius fracture. And ulnar head dislocation associated with disruption of distal radioulnar ligament is unusual. Among thease injury types. volar dislocation of ulnar head in the distal radioulnar joint is not common and it is misdiagnosis frequently. So it needs to surgical operation frequently. The author reviews this injury with the relevant literature.
