Tarsal Tunnel Syndrome

Tarsal tunnel syndrome is an entrapment neuropathy (pressure on nerve) of the tibial nerve as it courses through the inside aspect of the foot and ankle.

Symptoms:
Pain, numbness, burning and electrical sensations may occur along the course of the nerve, which includes the inside of the ankle, heel, arch and bottom of foot. Symptoms are usually worsened with increased activity such as walking or exercise. Prolonged standing in one place may also be an aggravating factor.

Cause:
There are a variety of factors that may cause tarsal tunnel syndrome. These may include repetitive stress with activities, flat feet, and excess weight. Additionally, any lesion that occupies space within the tarsal tunnel region may cause pressure on the nerve and subsequent symptoms. Examples include tendonitis, hematoma, tumor, varicose veins and lower extremity edema.

Diagnosis:
The diagnosis of tarsal tunnel is made primarily by the clinic experience of Dr. Campbell. A Tinel's sign (radiating pain upon tapping the nerve) may be elicited. Temporary relief may be obtained with a diagnostic local anesthetic injection. Electrodiagnostic studies such as nerve conduction velocity (EMG/NCV) testing may also prove useful. Magnetic resonance imaging (MRI) may also help to evaluate for local pathology or space occupying lesions.
