Volar dislocation of the metacarpophalangeal joint of the thumb: A case report

Abstract

We present an 18 year-old patient with a volar dislocation of the metacarpophalangeal joint of the thumb. Open reduction was performed through a dorsal incision. Because of the soft tissue interposition such as dorsal capsule, volar plate, dislocated extensor pollicis longus and brevis tendons, ruptured ulnar collateral ligament; open reduction, soft tissue and ligament repair are recommended for this type of thumb dislocations.
