Major arteries and nerves of the anterior elbow region

The brachial artery runs along the anteromedial aspect of the humerus. As the artery extends into the forearm, it splits into the radial and ulnar artery. The median nerve crosses the elbow joint with the brachial artery. The anterior interosseous nerve is the branch of the median nerve most commonly injured after supracondylar fractures in children. The radial nerve runs lateral to the humerus before crossing the elbow. The ulnar nerve crosses the elbow posterior to the medial epicondyle in the cubital tunnel.
