Origin

The anterior lateral malleolar artery arises from the anterior tibial artery on the anterior surface of the distal tibia.

Course

The anterior lateral malleolar artery travels inferolaterally, deep to the tendons of the extensor digitorum longus and the fibularis tertius muscles to wrap around the lateral malleolus of the fibula.

Branches

There are no named branches, however, the anterior lateral malleolar artery anastomoses with the perforating and lateral malleolar branches of the fibular artery and the lateral tarsal artery to form the lateral malleolar network.

Supplied Structures

The anterior lateral malleolar artery supplies the lateral aspect of the ankle and the inferior tibiofibular joint.

Artery

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
