Recurrent interosseous artery

Looks like

A small branch of the posterior interosseous artery in the forearm running back up to the elbow.

What it does

Joins the arterial network around the elbow, a backup path around the joint.

Keeping it well

Rarely a problem; matters in elbow surgery and forearm flaps.
