Origin
The lateral tarsal artery arises from the dorsalis pedis artery. It may originate at the junction of the head and neck of the talus bone (in approximately 60% of individuals), at the ankle joint (in approximately 20% of individuals), or distal to the talonavicular joint (in approximately 20% of individuals) (Tubbs, Shoja and Loukas, 2016).
Course
From its origin, the lateral tarsal artery extends laterally, deep to the extensor digitorum brevis muscle, and contributes to the lateral malleolar network.
Branches
There are no named branches; however, the lateral tarsal artery aids in the formation of the lateral malleolar network via its anastomosis with the lateral malleolar branches of the fibular artery, anterior lateral malleolar artery, and the perforating branch of the fibular artery.
Supplied Structures
The lateral tarsal artery supplies the extensor digitorum brevis muscle and the articulations between the tarsal bones.
