Origin
The calcaneal branches of the posterior tibial artery originate from the posterior tibial artery just before its terminal bifurcation in the distal leg.
Course
The calcaneal branches of the posterior tibial artery extend through the flexor retinaculum of the foot and runs along the medial and posterior aspects of the calcaneus.
Branches
There are no named branches, however, the calcaneal branches of the posterior tibial artery anastomose with the corresponding calcaneal branches of the fibular artery.
Supplied Structures
The calcaneal branches contribute to the supply of the calcaneus tendon, cutaneous tissue in the heel, and the calcaneal bursa that lies between the tendon and the calcaneus. It also supplies the muscles on the medial aspect of the plantar surface of the foot.

Posterior Tibial Artery
The posterior tibial artery then enters the calcaneal canal underneath the flexor retinaculum and bifurcates into the medial and lateral plantar arteries at the level of the transverse septum, between the abductor hallucis longus and the flexor digitorum brevis muscles.
