Function

Contents

The tibial nerve, the posterior tibial artery, the posterior tibial vein, and the flexor tendon travel in bundles along this path through the tarsal tunnel, in the following sequence from the antero-medial to the postero-lateral:

• Tibialis posterior tendon
• Flexor digitorum longus tendon
• Posterior tibial artery
• Posterior tibial vein
• Tibial Nerves
• Flexor hallucis longus tendon

Inside the tunnel, the nerve is divided into three different paths. One nerve (calcaneal) continues to the heel, the other two (medial plantary nerve and lateral plantary nerve) continue down the leg.

Clinical interests

Tarsal tunnel syndrome

Tarsal tunnel syndrome is the most frequently reported nerve trap of the ankle and is analogous to the wrist carpal tunnel. People with tarsal tunnel syndrome experience pain in the plantar aspect of the foot mostly at night. Load bearings increase the pain and weakness found in intrinsic leg muscles with positive Tinel signs in the tunnel. There is no tenderness in the plantar foot, although this is usually the main site of complaints.
