PURPOSE: To describe the intraosseous arterial anatomy of the proximal ulna. METHODS: We used 9 fresh-frozen, above-elbow amputations to map the intraosseous arterial supply using the Spalteholtz technique. We treated 3 additional above-elbow amputations similarly, and then dissected them to map the extraosseous arterial supply. We recorded the extraosseous arterial patterns and compared them with the intraosseous arterial findings. RESULTS: The intraosseous arterial supply to the proximal ulna is derived primarily from a large nutrient vessel, a branch of the ulna artery, entering the anterior cortex of the ulna distal to the coronoid base, and from 2 medium-sized branches of the posterior and medial arcade entering near the olecranon tip. A watershed area is seen between these 2 vessel groups, halfway between the tips of the olecranon and coronoid. CONCLUSIONS: The arterial supply of the proximal ulna is relatively consistent and flows in opposite directions from the 2 separate areas.
