Radial collateral artery

Last revised by Daniel J Bell on 2 Aug 2021

The radial collateral artery is one of the two terminal branches of the deep brachial artery. As it descends in the distal part of the posterior compartment of the arm, it pierces the lateral intermuscular septum and contributes to the arterial anastomosis of the elbow specifically the radial recurrent artery (from the radial artery) in the proximal aspect of the posterior compartment of the forearm.
