Concomitant Bennett's fracture-dislocation with a trapezium fracture: A case report and review of the literature.

Fractures of the trapezium occur infrequently, accounting for only 3.5 % of all carpal fractures. Trapezium fractures with concomitant Bennett's fracture-dislocations are exceedingly rare without a consensus on treatment recommendations. Here, we present a case of a simultaneous Bennett's fracture with a trapezium fracture in a pediatric patient. Our patient was treated with open reduction and internal fixation. Clinically, the patient was pain free with range of motion comparable to his uninjured side and without joint instability. A review of the literature reveals only twelve other cases reported in adult patients all of which were male with an average age of twenty-eight at the time of injury. Open reduction is the most popular treatment approach, but closed reduction can also be utilized with success in these injuries. While there is a large degree of heterogeneity of outcome reporting methodology, most patients have satisfactory outcomes and return to function comparable to their contralateral side.
