The tarsal tunnel is a passage found along the inner leg underneath the medial malleolus of the ankle.

Contents
The tibial nerve, posterior tibial artery, posterior tibial vein, and flexor tendons travel in a bundle along this pathway through the tarsal tunnel, in the following order from anteromedial to posterolateral:
- Tibialis posterior tendon.[2]
- Flexor digitorum longus tendon.[2]
- Posterior tibial artery.[2]
- Posterior tibial vein.[1]
- Tibial nerve.[2]
- Flexor hallucis longus tendon.[2]
In the tunnel, the tibial nerve splits into three different paths.[3] The medial calcaneal branches of the tibial nerve continues to the heel, while the medial plantar nerve and the lateral plantar nerve continue on to the bottom of the foot.[3]
Clinical significance

at the tunnel. There is no tenderness present on the plantar foot, though this is typically the primary site of complaint.
