What is Tarsal Tunnel Syndrome?

Tarsal tunnel syndrome is caused by compression of the posterior tibial nerve within the tarsal tunnel, a narrow space located inside the ankle near the ankle bones and covered by the flexor retinaculum ligament. This can be caused by various factors such as flat feet, enlarged structures within the tunnel like a ganglion cyst, injury-induced inflammation and swelling, or systemic diseases like diabetes or arthritis.

What are the syndromes of TTS?

• Pain or numbness in the ankle and foot, which may radiate down the leg or into the toes.
• Tingling or burning sensations in the foot.
• Weakness in the foot and ankle, making it difficult to stand on the affected foot.
• Difficulty moving the foot or toes.

How is TTS diagnosed?

Diagnosis of tarsal tunnel syndrome involves a physical examination, nerve conduction tests, and imaging tests like MRI or X-rays. Treatment options include:

• Non-surgical methods such as rest, ice, physical therapy, and medications to relieve pain and inflammation.
• Injection of corticosteroids to reduce inflammation.
• Orthotic devices to correct flat feet and reduce strain on the nerve.
• Surgical intervention in severe cases to relieve pressure on the nerve.

How can TTS be prevented?

Prevention of tarsal tunnel syndrome includes maintaining good posture, avoiding activities that put repetitive stress on the feet and ankles, and wearing shoes that provide adequate support.
