Ankle sprains are caused by an unnatural twisting or force on the ankle bones of the foot, often resulting in one or more ligaments on the outside of the ankle to be stretched or torn. If not properly treated, ankle sprains could develop into long-term problems.
Bunions are misaligned big toe joints that can become swollen and tender, causing the first joint of the big toe to slant outward, and the second joint to angle toward the other toes.
Flat feet are a common condition. In infants and toddlers, the longitudinal arch is not developed and flat feet are normal. The arch develops in childhood, and by adulthood, most people have developed normal arches.
Hammertoe is a deformity of the second, third or fourth toes. In this condition, the toe is bent at the middle joint, resembling a hammer. Left untreated, hammertoes can become inflexible and require surgery.
Diabetes and Your Feet
With a diabetic foot, a wound as small as a blister from wearing a shoe that's too tight can cause a lot of damage. Diabetes decreases blood flow, so injuries are slow to heal.
Plantar fasciitis (or heel pain) is commonly traced to an inflammation on the bottom of the foot. Our practice can evaluate arch pain, and may prescribe customized shoe inserts called orthoses to help alleviate the pain.
Corns and calluses are protective layers of compacted, dead skin cells. They are caused by repeated friction from skin rubbing against bony areas or against an irregularity in a shoe. Corns ordinarily form on the toes and calluses on the soles of the feet.
A chronic infection caused by various types of fungus, Athlete's foot is often spread in places where people go barefoot such as public showers or swimming pools.
What Is the Tarsal Tunnel?
The tarsal tunnel is a narrow space that lies on the inside of the ankle next to the ankle bones. The tunnel is covered with a thick ligament (the flexor retinaculum) that protects and maintains the structures contained within the tunnel—arteries, veins, tendons, and nerves. One of these structures is the posterior tibial nerve, which is the focus of tarsal tunnel syndrome.
What Is Tarsal Tunnel Syndrome?
Tarsal tunnel syndrome is a compression, or squeezing, on the posterior tibial nerve that produces symptoms anywhere along the path of the nerve running from the inside of the ankle into the foot.
Tarsal tunnel syndrome is similar to carpal tunnel syndrome, which occurs in the wrist. Both disorders arise from the compression of a nerve in a confined space.
Tarsal tunnel syndrome is caused by anything that produces compression on the posterior tibial nerve, such as:
- A person with flat feet is at risk for developing tarsal tunnel syndrome, because the outward tilting of the heel that occurs with “fallen” arches can produce strain and compression on the nerve.
- An enlarged or abnormal structure that occupies space within the tunnel can compress the nerve. Some examples include a varicose vein, ganglion cyst, swollen tendon, and arthritic bone spur.
- An injury, such as an ankle sprain, may produce inflammation and swelling in or near the tunnel, resulting in compression of the nerve.
- Systemic diseases such as diabetes or arthritis can cause swelling, thus compressing the nerve.
Patients with tarsal tunnel syndrome experience one or more of the following symptoms:
- Tingling, burning, or a sensation similar to an electrical shock
- Pain, including shooting pain
Symptoms are typically felt on the inside of the ankle and/or on the bottom of the foot. In some people, a symptom may be isolated and occur in just one spot. In others, it may extend to the heel, arch, toes, and even the calf.
Sometimes the symptoms of the syndrome appear suddenly. Often they are brought on or aggravated by overuse of the foot, such as in prolonged standing, walking, exercising, or beginning a new exercise program.
It is very important to seek early treatment if any of the symptoms of tarsal tunnel syndrome occur. If left untreated, the condition progresses and may result in permanent nerve damage. In addition, because the symptoms of tarsal tunnel syndrome can be confused with other conditions, proper evaluation is essential so that a correct diagnosis can be made and appropriate treatment initiated.
The foot and ankle surgeon will examine the foot to arrive at a diagnosis and determine if there is any loss of feeling. During this examination, the surgeon will position the foot and tap on the nerve to see if the symptoms can be reproduced. He or she will also press on the area to help determine if a small mass is present.
Advanced imaging studies may be ordered if a mass is suspected or if initial treatment does not reduce the symptoms. Studies used to evaluate nerve problems—electromyography and nerve conduction velocity (EMG/NCV)—may be ordered if the condition shows no improvement with non-surgical treatment.
A variety of treatment options, often used in combination, are available to treat tarsal tunnel syndrome. These include:
- Rest. Staying off the foot prevents further injury and encourages healing.
- Ice. Apply an ice pack to the affected area, placing a thin towel between the ice and the skin. Use ice for 20 minutes and then wait at least 40 minutes before icing again.
- Oral medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, help reduce the pain and inflammation.
- Immobilization. Restricting movement of the foot by wearing a cast is sometimes necessary to enable the nerve and surrounding tissue to heal.
- Physical therapy. Ultrasound therapy, exercises, and other physical therapy modalities may be prescribed to reduce symptoms.
- Injection therapy. Injections of a local anesthetic provide pain relief, and an injected corticosteroid may be useful in treating the inflammation.
- Orthotic devices. Custom shoe inserts may be prescribed to help maintain the arch and limit excessive motion that can cause compression of the nerve.
- Shoes. Supportive shoes may be recommended.
- Bracing. Patients with flatfoot or those with severe symptoms and nerve damage may be fitted with a brace to reduce the amount of pressure on the foot.
When is Surgery Needed?
Sometimes surgery is the best option for treating tarsal tunnel syndrome. The foot and ankle surgeon will determine if surgery is necessary and will select the appropriate procedure or procedures based on the cause of the condition.
