What Is Tarsal Tunnel Syndrome?

Dr. Jeb Cormier

Tarsal tunnel syndrome is a compression, or squeezing, on the posterior tibial nerve that produces symptoms anywhere along the path of the nerve running from the inside of the ankle into the foot.

Tarsal tunnel syndrome is similar to carpal tunnel syndrome, which occurs in the wrist. Both disorders arise from the compression of a nerve in a confined space.

 Causes

Tarsal tunnel syndrome is caused by anything that produces compression on the posterior tibial nerve, such as:

  • A person with flat feet is at risk for developing tarsal tunnel syndrome, because the outward tilting of the heel that occurs with fallen arches can produce strain and compression on the nerve.
  • An enlarged or abnormal structure that occupies space within the tunnel can compress the nerve. Some examples include a varicose vein, ganglion cyst, swollen tendon or arthritic bone spur.
  • An injury, such as an ankle sprain, may produce inflammation and swelling in or near the tunnel, resulting in compression of the nerve.
  • Systemic diseases, such as diabetes or arthritis, can cause swelling, thus compressing the nerve.

Symptoms

Patients with tarsal tunnel syndrome experience one or more of the following symptoms:

  • Tingling, burning or a sensation similar to an electrical shock
  • Numbness
  • Pain, including shooting pain

Symptoms are typically felt on the inside of the ankle and/or on the bottom of the foot. In some people, a symptom may be isolated and occur in just one spot. In others, it may extend to the heel, arch, toes and even the calf.

Sometimes the symptoms of the syndrome appear suddenly.  They are often brought on or aggravated by overuse of the foot, such as in prolonged standing, walking, exercising or beginning a new exercise program.

It is important to seek early treatment if any of the symptoms of tarsal tunnel syndrome occur. If left untreated, the condition progresses and may result in permanent nerve damage. In addition, because the symptoms of tarsal tunnel syndrome can be confused with other conditions, proper evaluation is essential so that a correct diagnosis can be made and appropriate treatment initiated.

Nonsurgical Treatment

Many treatment options, often used in combination, are available to treat tarsal tunnel syndrome. These include:

  • Rest. Staying off the foot prevents further injury and encourages healing.
  • Ice. Apply an ice pack to the affected area, placing a thin towel between the ice and the skin. Use ice for 20 minutes and then wait at least 40 minutes before icing again.
  • Oral medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, help reduce the pain and inflammation.
  • Immobilization. Restricting movement of the foot by wearing a cast is sometimes necessary to enable the nerve and surrounding tissue to heal.
  • Physical therapy. Ultrasound therapy, exercises and other physical therapy modalities may be prescribed to reduce symptoms.
  • Injection therapy. Injections of a local anesthetic provide pain relief, and an injected corticosteroid may be useful in treating the inflammation.
  • Orthotic devices. Custom shoe inserts may be prescribed to help maintain the arch and limit excessive motion that can cause compression of the nerve.
  • Shoes. Supportive shoes may be recommended.
  • Bracing. Patients with flatfoot or those with severe symptoms and nerve damage may be fitted with a brace to reduce the amount of pressure on the foot.
