Simultaneous Rupture of Ulnar and Radial Collateral Ligaments of the First Metacarpophalangeal Joint: A Case Report

Simultaneous injury to the ulnar and radial collateral ligaments of the first metacarpophalangeal joint is rare. We report an unusual case of rupture of the radial and ulnar collateral ligaments of the first metacarpophalangeal joint. We performed reconstruction with an autogenous palmaris longus graft and suture anchors. At the 18-month follow-up point after surgery, no residual instability was observed.
