Anatomical terminology

It is accompanied by the anterior tibial vein, along its course.

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

CourseEdit

 
Back of left lower extremity, showing origin of anterior tibial artery before it continues on the anterior side.

The artery 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.

BranchesEdit

Clinical importanceEdit

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