Anterior Tibial Artery
Dorsalis Pedis Artery
The Anterior Tibial artery is a branch of the popliteal that passes anterolaterally through the gap between the neck of the fibula and the tibial shaft superior to the edge of the interosseous membrane. It is the vessel of the anterior compartment. It follows the lateral edge of the the tibialis anterior tendon onto the anterior surface of the tibial shaft just above the ankle joint (where its pulse can be felt), and then follows a course straight down across the ankle. At the level of the ankle joint the anterior tibial artery is crossed superficially by the tendon of extensor hallucis longus. Below the point of crossing, there is a territorial name change – from anterior tibial to Dorsalis Pedis artery. The dorsalis pedis artery lies lateral to the extensor hallucis longus tendon on the dorsal surface of the tarsal bones. Its pulse may be felt here (however, the vessel is small or absent in 10 to 15 percent of cases). Upon reaching the first intermetatarsal space the dorsalis pedis artery changes its name to the deep plantar artery and dives between the two heads of the first dorsal interosseous muscle.
