Tarsal Tunnel

Tarsal Tunnel

Overview

The tarsal tunnel is located on the inside of your ankle. This passageway is formed by three bones (the tibia, talus, and calcaneus), which are covered by a fibrous connective tissue band (flexor retinaculum). The nerves, blood vessels, and tendons that help the foot move run through the tarsal tunnel. One of those nerves is called the tibial nerve.  When the tibial nerve is compressed in the tunnel, numbness, tingling, weakness, and muscle damage in the foot can happen.
