Lateral plantar artery

  • The lateral plantar artery (also called external plantar artery, latin: arteria plantaris lateralis) is one of the terminal branches of the posterior tibial artery.

    This artery runs distally to the base of the fifth metatarsal bone, turns medially, reaching the interval between the first and second metatarsal bases. Then the lateral plantar artery unites with the deep plantar branch of the dorsalis pedis artery, completing the plantar branch.

    The lateral plantar artery gives off muscular branches, superficial branches, anastomotic branches and a calcaneal branch.  

    The lateral plantar artery and its branches supply the adjoining muscles, and the skin and subcutaneous tissues on the lateral side of the sole.
