Anterior tibial artery
The anterior tibial artery is one of the important arteries of the lower leg. It runs slightly above the inter-osseous membrane and enters the front part of the leg, going down to the lateral foot surface. The anterior tibial vein runs parallel to this artery throughout its course. It crosses the front part of the ankle joint, where the dorsalis pedis artery makes its beginning. The key function of this artery is to supply blood to the muscles in the anterior part of the leg. As this artery goes across the inter-osseous membrane, it branches off into the dorsalis pedis. This further branches out into tarsal, lateral, and medial branches, where the artery culminates by intersecting the deep plantar and arcuate arteries. The deep planter artery branches out to the first and second toes, and goes from the middle of the inter-osseous muscle to the deep plantar surface. The typical surgical exposure of the anterior tibial artery is made with a long incision in the lateral part of the calf above the mid region of the anterior compartment.
