If you have suffered a severe joint dislocation or fracture, please Schedule an appointment with one of our orthopedic specialists as soon as possible.

What Is Tarsal Tunnel Release?

Tarsal tunnel release is a surgical procedure performed to alleviate the symptoms associated with tarsal tunnel syndrome. The tarsal tunnel is a narrow passageway located on the inside of the ankle, formed by the bones and soft tissues of the foot. It contains important structures such as nerves, blood vessels, and tendons. When this tunnel becomes compressed or damaged, it can result in tarsal tunnel syndrome, causing pain, numbness, and tingling sensations in the foot and ankle.

Tarsal Tunnel Release Procedure:

During a tarsal tunnel release, the surgeon aims to decompress the tarsal tunnel by cutting the ligament that forms its roof. This relieves pressure on the structures within the tunnel and allows for improved nerve function and reduced symptoms. The procedure can be performed through open surgery or minimally invasive techniques, such as endoscopy.

Before undergoing tarsal tunnel release, a thorough evaluation is conducted, including a physical examination and diagnostic tests like nerve conduction studies and imaging. These help the surgeon determine the extent of nerve compression and plan the appropriate surgical approach.

The surgical procedure typically begins with the administration of anesthesia to ensure the patient’s comfort throughout the operation. In open surgery, an incision is made along the inside of the ankle, providing access to the tarsal tunnel. The surgeon carefully identifies and protects the surrounding nerves, blood vessels, and tendons while visualizing the ligament that forms the roof of the tunnel. The ligament is then divided, allowing the decompression of the tunnel and relieving pressure on the structures within.

Alternatively, in minimally invasive approaches like endoscopy, small incisions are made, and a tiny camera and specialized instruments are inserted to visualize and release the ligament under direct guidance. This technique offers the advantages of smaller incisions, reduced tissue trauma, and potentially faster recovery.

Postoperative Care:

After completing the tarsal tunnel release, the incisions are closed, and a sterile dressing is applied to the surgical site. The patient may be provided with a supportive splint or cast to protect the foot and ankle during the initial healing phase. Physical therapy and rehabilitation exercises may be recommended to restore strength, flexibility, and function to the foot. As with any surgical procedure, there are potential risks and complications associated with tarsal tunnel release. These may include infection, nerve injury, blood vessel damage, excessive scar tissue formation, or incomplete relief of symptoms. It is important for patients to follow the post-operative instructions provided by the surgeon and attend follow-up appointments to monitor their progress.


In conclusion, tarsal tunnel release is a surgical procedure designed to relieve the symptoms of tarsal tunnel syndrome by decompressing the tarsal tunnel. Whether performed through open surgery or minimally invasive techniques, the goal is to alleviate pressure on the structures within the tunnel and restore normal nerve function. With careful evaluation, appropriate surgical planning, and post-operative care, tarsal tunnel release can provide significant relief and improve the quality of life for individuals suffering from tarsal tunnel syndrome.
