Open dislocation of the proximal interphalangeal joint of the little finger subsequent to chronic radial collateral ligament injury : a case report of primary ligament reconstruction with a half-slip of the flexor digitorum superficialis : Case Report

Open dislocation of the proximal interphalangeal (PIP) joint is relatively rare. We report a case of a 32-year-old man who had open dislocation of the PIP joint of the little finger while playing American football. He had a history of chronic radial collateral ligament injury. We reconstructed the radial collateral ligament with a half-slip of the flexor digitorum superficialis tendon.
