Structure

Course

The anterior tibial artery is a branch of the popliteal artery.[1] It originates at the distal end of the popliteus muscle posterior to the tibia. The artery typically passes anterior to the popliteus muscle prior to passing between the tibia and fibula through an oval opening at the superior aspect of the interosseus membrane. The artery then descends between the tibialis anterior and extensor digitorum longus muscles.

It is accompanied by the anterior tibial vein, and the deep peroneal nerve, along its course.

It crosses the anterior aspect of the ankle joint, at which point it becomes the dorsalis pedis artery.

Branches

The branches of the anterior tibial artery are:

Clinical significance

As the artery passes medial to the fibular neck, it becomes vulnerable to damage during a tibial osteotomy.
