Volar metacarpophalangeal joint dislocation.

Volar dislocation of the metacarpophalangeal joint is a very rare clinical finding. A volar dislocation of the metacarpophalangeal joint of the left index finger in a 44 year old man is reported. Closed reduction proved unsuccessful requiring subsequent open reduction and internal fixation via a combined dorsal and volar approach. The presentation, mechanism of injury and treatment of this case and other previously reported cases are discussed.
