The tarsal tunnel is a narrow space that is on the inside of the ankle next to the ankle bones. It is covered with a thick ligament that protects structures within the tunnel such as arteries, veins, tendons and nerves. Tarsal tunnel syndrome is a compression or squeezing on the posterior tibial nerve that produces symptoms from the inside of the foot into the ankle. Some symptoms of tarsal tunnel syndrome include numbness, a shooting pain, and tingling or burning sensations that are similar to an electric shock. Some causes are diabetes which can cause swelling on the nerve, an injury like an ankle sprain that can produce swelling in or near the tunnel, and flat feet due to the outward tilting of the heel. It is important to go see your local podiatrist if you feel you exhibit any of these symptoms. 

Tarsal tunnel syndrome can be very uncomfortable to live with. If you are experiencing tarsal tunnel syndrome, contact Dr. Robert Graser of Graser Podiatry and Bunion Surgery Institute. Our doctor can provide the care you need to keep you pain-free and on your feet.

Tarsal Tunnel Syndrome

Tarsal tunnel syndrome, which can also be called tibial nerve dysfunction, is an uncommon condition of misfiring peripheral nerves in the foot. The tibial nerve is the peripheral nerve in the leg responsible for sensation and movement of the foot and calf muscles. In tarsal tunnel syndrome, the tibial nerve is damaged, causing problems with movement and feeling in the foot of the affected leg.

Common Cause of Tarsal Tunnel Syndrome

• Involves pressure or an injury, direct pressure on the tibial nerve for an extended period of time, sometimes caused by other body structures close by or near the knee.
• Diseases that damage nerves, including diabetes, may cause tarsal tunnel syndrome.
• At times, tarsal tunnel syndrome can appear without an obvious cause in some cases.

The Effects of Tarsal Tunnel Syndrome

• Different sensations, an afflicted person may experience pain, tingling, burning or other unusual sensations in the foot of the affected leg.
• The foot muscles, toes and ankle become weaker, and curling your toes or flexing your foot can become difficult.
• If condition worsens, infections and ulcers may develop on the foot that is experiencing the syndrome.

A physical exam of the leg can help identify the presence of tarsal tunnel syndrome. Medical tests, such as a nerve biopsy, are also used to diagnose the condition. Patients may receive physical therapy and prescriptive medication. In extreme cases, some may require surgery.
