Bridge Plating of Second and Third Carpometacarpal Fracture Dislocations: A Case Report of Rare Injury.

Introduction: Fracture dislocations of the second and third carpometacarpal (CMC) joints are a rare injury, often associated with high-energy trauma that can lead to significantly compromised hand function if missed. Case Report: A 23-year-old female presented with a subacute right second and third CMC fracture dislocations after a rollover ATV accident. Open reduction and fixation of the second and third CMC fracture dislocations with a bridge plating construct was performed. At 12 weeks postoperatively, there were no complaints of pain. Hardware was removed at 5 months postoperatively. One year postoperatively, the patient had no significant stiffness, pain, or functional deficits. Conclusion: Despite the subacute presentation and concern for devitalized bone, repair of the second and third CMC base fracture dislocations with bridge plating is a safe option for the CMC joints without fusion with good results.
