Carpometacarpal Joint Dislocation of the Thumb Associated with Fracture of the Trapezium: A Case Report

ABSTRACT

We report a dislocation of the thumb carpometacarpal joint associated with an oblique fracture of the trapezium. This case was treated with open reduction and internal fixation using two Kirschner wires for the trapezial fracture and repair of the ruptured dorsal capsular ligament and additional Kirschner wire fixation for the carpometacarpal joint stability. At the 12 months follow-up examination, there was no pain or chronic instability. There was no evidence of post-traumatic arthritic changes.
