Abstract

Pure dislocation of 1st carpometacarpal (CMC) joint is uncommon and may be missed initially. The neglected dislocation of 1st CMC joint can be reduced by open method and required capsular repair or ligament reconstruction for stability of 1st CMC joint. We experienced the patient with an old dislocation of 1st CMC joint which was recognized 9 months after the injury. Open reduction was impossible, therefore we treated by the trapezial excision and ligament reconstruction tendon interposition arthroplasty, resulting in painless functional joint.
