Course
The medial calcaneal nerve is a branch of the tibial nerve. It arises in the tarsal tunnel – an area posterior to the medial malleolus at the ankle.
After its origin, the nerve moves superficially to perforate the flexor retinaculum (the roof of the tarsal tunnel).
It terminates by dividing into several branches within innervate the skin of the medial heel.
