Thrombosis of the distal ulnar artery secondary to a blunt injury to the hand may give characteristic neurological and vascular symptoms, yet is easily confused with other conditions. Recognition of this entity is important so that the proper mode of treatment may be applied. Resection of the thrombosed segment and ligation of the proximal and distal ends is the treatment of choice. Satisfactory results were obtained in our series of ten patients with resection of the thrombosed Segment.
