Superior Ulnar Collateral Artery
Abstract
The superior ulnar collateral may arise together with the profunda brachii (22%) or from a trunk common to several other branches of the axillary and brachial arteries. When absent, the inferior ulnar collateral takes its place. This artery frequently supplies the nutrient artery to the humerus, and provides a branch to the triceps and to the elbow joint. A case was reported where the radial recurrent artery was absent, but was replaced by the anterior ulnar recurrent, which crossed over and ascended on the outer (lateral) side of the elbow joint.
