Arteriovenous fistula secondary to recurrent metacarpophalangeal joint dislocation: a case report.

Acquired traumatic arteriovenous fistula in the hand is rare, and only a few cases have been reported in the literature. It should be considered as a possible complication when there is a persistent palpable lesion after the traumatic swelling in the hand has resolved. We report a case of a rare arteriovenous fistula secondary to recurrent metacarpophalangeal joint dislocation.
