Tarsal Tunnel

Tarsal tunnel syndrome occurs when the tibial nerve, which runs through the ankle, becomes squeezed or is under abnormal pressure and it becomes inflamed.

Tarsal tunnel syndrome occurs when the tibial nerve, which runs through the ankle, becomes squeezed or is under abnormal pressure and becomes inflamed.


There are a few potential causes of tarsal tunnel syndrome, like soft tissue masses or inflamed vessels (spider veins around the ankle), flat feet, over-pronation, high arches, ankle joint instability, a sprained ankle, diabetes, and arthritis.


It can also be caused by nearby foot problems that can add pressure to the nerve, like a bone spur, ganglion cyst, tendonitis, or an inflamed tendon.

Diagnosing

To diagnose tarsal tunnel syndrome, our providers conduct a thorough exam of the foot and ankle, including various tests to assess the nerve’s function.


We may also order a Nerve Conduction Velocity (NCV) test which confirms tarsal tunnel, or will rule out any nerve entrapment. X-rays or MRIs may be ordered to evaluate the extent of the condition and rule out other issues.

Our patients with tarsal tunnel syndrome often report the following symptoms:

  • Pain, tingling, or burning sensations along the sole of the foot or toes.

  • Numbness in the foot or toes.

  • Increased pain when standing or walking.

  • A feeling of weakness in the foot.

Treatment for tarsal tunnel syndrome typically focuses on reducing pain and inflammation, as well as restoring function. Common approaches include:

  • Rest: Avoiding activities that exacerbate the pain.

  • Physical Therapy: Exercises to strengthen the foot and improve flexibility.

  • Orthotics: Custom foot supports to relieve strain on the tibial nerve.

  • Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and swelling.

  • Surgery: In severe cases, surgical intervention may be necessary to relieve pressure on the nerve.

Preventative measures include wearing appropriate footwear, maintaining a healthy weight, and performing exercises that strengthen the foot and ankle.
