Tarsal Tunnel Syndrome

What is Tarsal Tunnel Syndrome?

Tarsal tunnel syndrome is a condition that occurs when the posterior tibial nerve, which runs through the tarsal tunnel on the inside of the ankle, becomes compressed or squeezed. This can cause a variety of symptoms in the foot, including pain, tingling, numbness, or a burning sensation – often compared to the carpal tunnel syndrome in the wrist.

The Anatomy of the Issue

The tarsal tunnel is a narrow space that lies on the inside of the ankle next to the ankle bones. It is covered with a thick ligament that protects and maintains the structures contained within the tunnel—arteries, veins, tendons, and nerves. One of these structures, the posterior tibial nerve, is the focus when it comes to tarsal tunnel syndrome.
