Arterial anastomosis of the elbow

Radiopaedia • CC-by-nc-sa 3.0 • de

The periarticular arterial anastomosis of the elbow consists of several arteries that supply the elbow joint and its supporting structures. It functions to allow blood to flow around the elbow joint no matter which position the joint is in. The arteries that contribute include:

from the brachial artery
- superior ulnar collateral artery
- inferior ulnar collateral artery
from the deep brachial artery
- middle collateral artery
- radial collateral artery
from the radial artery
- radial recurrent artery
from the ulnar artery

Accompanying veins also form a rich venous plexus.
