Volar dislocation of the thumb metacarpophalangeal joint with acute repair of the ulnar collateral ligament

Abstract

Volar dislocations of the thumb metacarpophalangeal joint are uncommon and can be associated with rupture of the ulnar collateral ligament (UCL). We report a case where a volar thumb dislocation was successfully closed reduced, but instability required open repair of the UCL. Early motion protocol helped achieve favorable results.
