You have probably heard of carpal tunnel syndrome – which is an entrapment of a nerve in your wrist that causes numbness, tingling and pain in the hand. Tarsal tunnel syndrome is a similar condition but affects the foot. It is caused by irritation of the tarsal nerve that travels on the inside of the ankle, behind the ankle bone. Most often the irritation is caused by excessive stretch on the nerve and is often associated with flat feet.

Tarsal tunnel syndrome can cause many types of foot pain including burning pain, shooting pain, sharp pain, tingling numbness and aching. It can cause heel pain, ankle pain, bottom of the foot pain and even toe pain. .

Treatment – Non-Surgical

We feel strongly that the initial treatment of tarsal tunnel syndrome should be conservative. Surgery should only be a last resort. Custom orthotics are often our first line of treatment but to be effective in relieving symptoms of tarsal tunnel syndrome a very specific orthotic prescription should be used. Several research studies over the past 8 years have indicated exactly how an orthotic should be prescribed to best alleviate tension and compression on the tarsal nerve.

How Should Orthotics Be Made to Treat Tarsal Tunnel Syndrome?

There are several studies (listed below) that indicate exactly how orthotics should be made to treat tarsal tunnel syndrome. The studies show that to decrease tension on the tibial nerve the orthotics should act to do three things:

  • Raise the heel. In order to do this we incorporate lifts under the heel of the orthotic. The thickness of the lift depends on the findings from our examination
  • Stop the heel from rolling in.To stop the heel from rolling in we will make the orthotic deeper around the heel and incorporate some wedging built-in to the orthotic in order to provide force that decreases the eversion (rolling-in) of the heel.
  • Stop the arch of the foot from collapsing. To do this we prescribe a total contact orthotic. This is the only type that will stop arch collapse sufficiently to limit tension on the tibial nerve.

Other treatments for tarsal tunnel syndrome include anti-inflammatory measures, injection, shoe changes and, if all conservative treatment fails, surgical decompression of the tarsal nerve.

Treatment – Surgical

If all conservative treatment fails, then surgery may be beneficial. The goal of surgery is to reduce tension and pressure on the tarsal nerve. The video above provides good information on diagnosis and surgery of tarsal tunnel syndrome.

Home Treatments for Tarsal Tunnel Syndrome

This is a problem that should be treated professionally rather than at home. If left untreated it only tends to get worse. If, however, you want to try some home treatments the goal is to try to reduce tension on the tarsal nerve by supporting the arch as much as possible and stopping the heel from rolling in. So, if you want to try self treating tarsal tunnel syndromshoe for tarsal tunnel syndromee, try the following three treatments for three weeks. If you are not better by then, see a podiatrist.

1.  Wear a stable shoe that prevents the heel from rolling in. A good example are the Vionic walking shoes.  You can see the men’s Vionic Walking Shoe here and the women’s Vionic walking shoe herearch supports for tarsal tunnel syndrome.

2.  Wear a very stable arch support in your shoes. The ProLab P3 arch support is our recommended arch support for tarsal tunnel because it has a firm high arch and a wedge in the heel that helps stop the heel from rolling in.

3.  When you are not wearing shoes wear a flip-flop or sandal with extremely good arch support. The best on the market by far are the Vionic sandals found here.

Then wear these all the time for about three weeks.  Don’t go barefoot at all. If you are not 100% better at the end of three weeks, see a podiatrist right away.

Diagnosis

Diagnosis of tarsal tunnel syndrome is usually made via physical and biomechanical examination.  A common test for tarsal tunnel syndrome is called the “Kinoshita” or “Dorsiflexion-Eversion” test.

Advanced diagnostic testing including x-ray, MRI, and nerve conduction studies can help us determine the cause for specific cases of tarsal tunnel syndrome.

If you think you might have tarsal tunnel syndrome, make an appointment to see us as soon as possible in our Seattle office. This problem will usually get worse over time, so get treated early.
