title: Trapeziometacarpal joint dislocation complicated by a trapezium fracture: A case report and literature review.
abstract: The authors report and discuss the management of a 25-year-old male patient with a trapeziometacarpal joint dislocation complicated by a trapezium fracture. This injury combination is rare with only reported 15 cases. After closed reduction resulted in dorsal instability, anatomical reduction of the trapezium fracture and internal screw fixation were performed using an open approach. This fixation stabilized the joint but was fragile due to the small fragment size. For this reason, ligament reconstruction using half of the flexor carpi radialis tendon was added. At the last follow-up, 16 months later, the trapeziometacarpal joint was stable with a normal range of motion, but the patient had slight pain during physical effort and decreased pinch strength.
