title: Thrombosis of the digital arteries as the cause of a class IIA ring avulsion.
abstract: I describe a patient who had a dusky finger after a ring avulsion injury. Although blood flow was initially good after removal of the ring, circulatory compromise later developed. Surgical exploration revealed thrombosis of both digital arteries, which was treated with thrombectomy. In such injuries, the circulatory status of the finger needs to be observed after ring removal in case delayed compromise occurs.
