Ring Avulsion Injury Treated by Interpositioning Vessel Graft with a Proper Palmar Digital Artery: A Case Report

ABSTRACT

Because of extensive vascular injury, reconstruction of ring avulsion injury is classically believed to be challenging for a hand surgeon. We report a case of ring avulsion injury treated by debridement of the damaged artery and interpositioning vessel graft with a healthy proper palmar digital artery, which lead to successful functional recovery.
