Origin

The medial and lateral plantar arteries are the terminal branches of the posterior tibial artery. The posterior tibial artery bifurcates into the medial and lateral plantar arteries in the region of the sustentaculum tali (Tubbs, Shoja and Loukas, 2016). The lateral plantar artery is the larger of these two vessels.

Course

The lateral plantar artery continues in a lateral direction on the plantar aspect of the quadratus plantae muscle, deep to the flexor digitorum brevis muscle. It then passes over the tendon of the fibularis longus muscle, continues distally along the cuboid, until it reaches the level of the base of the fifth metatarsal. It accompanies the lateral plantar nerve which sits medial to the artery.

At the base of the fifth metatarsal bone, the lateral plantar artery unites with the deep plantar artery from the dorsalis pedis artery to form the plantar arch.

Branches

The lateral plantar artery gives rise to a plantar metatarsal branch that extends along the lateral surface of the fifth metatarsal bone (Netter, 2011).

Supplied Structures

The lateral plantar artery supplies the lateral aspect of the sole of the foot, including muscular, cutaneous, and articular elements. It also contributes to the supply of the plantar aspect of the toes.

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.
