tarsal tunnel

Tarsal Tunnel is a space in the foot formed between bones and overlying fibrous tissue. Within the tarsal tunnel lies a nerve called the posterior tibial nerve.

Tarsal tunnel syndrome results when the posterior tibial nerve is compressed within the tarsal tunnel. This is very similar to carpal tunnel syndrome that you can have in your wrist. Both of these conditions result when a nerve is pinched within a small space.

When the posterior tibial nerve is compressed in the tarsal tunnel, patients commonly complain of numbness over the bottom of the foot, as well as complaints of pain, burning and tingling over the base of the foot and heel. It can be confused with plantar fascitis.

The cause of tarsal tunnel is unknown in most cases, but can be the result of fractures, bone spurs, ganglion and other benign tumors or foot deformities.

Treatment can consist of anti-inflammatory medications and possibly injection of cortisone into the area around the nerve. Orthotics can help to relieve the symptoms.

Surgery may be indicated where an incision is made to open up the tarsal tunnel and decrease pressure on the posterior tibial nerve. This procedure is similar to a carpal tunnel release in the hand.

If you are experiencing burning or numbness in your feet, a podiatrist should be consulted to make sure of what is causing the problem. To contact the office Dr. T. F. Vail, DPM, call 419-423-1888
