What is Tarsal Tunnel Syndrome?

Tarsal Tunnel Syndrome (TTS) is known as a compression neuropathy (nerve disorder due to squeezing of the nerve) in the ankle and foot. It is similar to Carpal Tunnel Syndrome, which occurs in your wrist, however far less common. In Latin, 'tarsal' means ankle, therefore Tarsal Tunnel Syndrome results from compression or damage to the posterior tibial nerve located in your tarsal canal, which runs through the small space along the inside of your ankle into the heel and sole of your foot. It causes a lot of pain in your foot, ankle and toes. This condition is slowly progressive and occurs more commonly after 30 - 40 years of age.

Often damage to your posterior tibial nerve in one location may affect the overall functioning of your nerve, so you are more at risk of suffering from compression in other areas along the nerve. The nerve sends signals along its length and also moves its own nutrients, which is necessary for optimal function. Nutrients move along the entire length of your nerve via axoplasms (jelly-like material that fills the cells of the axons). If the flow of these nutrients is blocked, your nerve tissue further from the area of compression does not receive the essential nutrients to fight off injuries, and your damage will get worse.

Other names and/or similar conditions:

• Tarsal Tunnel Neuropathy
• Entrapment Neuropathy Of The Tibial Nerve
• Posterior Tibial Neuropathy
• Compression Of The Tibial Nerve
• Posterior Tibial Neuralgia

Tarsal Tunnel Syndrome Anatomy

The tarsal tunnel is found between the thick, overlying fibrous tissue on one side of your foot and the underlying bones on your other side. The flexor retinaculum acts as the top of your tarsal tunnel. It forms a deep, band of fibrous connective tissue that surrounds the muscles and nerves in your lower leg and ankle. The top of the Calcaneus (largest tarsal bone that makes up the heel), the inner wall of the Talus (2nd largest tarsal bone that forms the ankle joint connecting the leg bones to the foot bones) and the inner/bottom part of the Tibia (shinbone) comprise the bottom of your tarsal tunnel. Your ankle and foot tendons, muscles, nerve, artery and vein pass through the Tarsal Tunnel to get to the bottom of your foot.

Your Posterior Tibial Nerve is found between the Posterior Tibial Muscle, the Flexor Digitorum Longus and the Flexor Hallucis Longus muscles in your lower leg/ankle. The Tibial Nerve moves behind the bump on the inside of your ankle (Medial Malleolus) and through the Tarsal Tunnel, where it then divides into nerve branches in the sole of your foot.

Symptoms of Tarsal Tunnel Syndrome

Although they vary from person to person, most of these symptoms are generally experienced on either the inside of the ankle and/or the bottom of the foot. The most common symptoms noted by those who suffer from Tarsal Tunnel Syndrome are:

• Tingling, burning, or prickling sensation (also known as paresthesias), in your foot (often in your arch, toe or heal).
• Vague or sharp pain, near the area where the nerve is squeezed (often in the sole of your foot, near your big toe, or along your nerve); this pain tends to be worse at night.
• Numbness, a loss of sensation in the area of skin that is supplied by the nerve.
• Atrophied (weakened) muscles in your inner foot (around the ball or arch of your foot) can affect your gait (the way you walk). You may have a tendency to overpronate (your foot rolls in too much), limp or feel uncoordinated as a result of too much pressure being placed on your foot.
• A lower foot deformity (like flat feet) can increase tension in the foot and may instigate the symptoms of TTS.

If left untreated, you are at risk of suffering from permanent nerve damage.

When treating Tarsal Tunnel Syndrome, rest the area as much as possible, apply ice for 10-20 minutes at a time for at least 3 times a day. Do this to the injured area for the first day to 3 days. If you have a cold / hot pack for the ankle and bottom of the foot, you will quickly find that frequent hot/cold treatments for these areas are much less troublesome, and you can do this while getting on with your day. Utilizing pack wrap is helpful in securing the packs to these areas. Note that the importance of the hot / cold treatment is very high, though when surveyed, most TTS sufferers never take advantage of this easy treatment step. Moist heat may be used after acute swelling of the ankle and foot has improved and rest prevents further progression of the injury. Ice will reduce initial inflammation and swelling and the moist heat circulates blood through the area to speed the healing process. This can be further helped by the use of ultrasound applications over the affected area, as it reduces swelling quickly and increases blood flow to the area.

The long term use of therapeutic ultrasound is common with this injury, as the application of ultrasound will:

Counteract atrophy in muscles and tendons.

Increase the elasticity of all tendons that pass through the tarsal tunnel.

Soften inelastic scar tissue from injured tendons / muscle fiber to the point where it is eventually re-absorbed by the body.

Decrease inflammation of tendons, and the flexor retinaculum (a fibrous sheath passing through the tarsal tunnel). All tendons in the tarsal tunnel are sheathed, and once tendons become inflamed, the sheath swells and can also become inflamed, and at the worst, infected. If you suspect you have any type of infection in the area, please consult a physician immediately as this can be very damaging if left untreated. (Never use ultrasound over anything suspected of being infected.)

Changes in footwear and orthotic arch supports, along with calf and foot stretching exercises have also been known to provide relief for individuals with chronic TTS.

A Final Word About Therapeutic Ultrasound

It is important to know that therapeutic ultrasound will alleviate TTS symptoms, but to truly treat TTS properly and prevent reoccurrence, an extended treatment term is required - 2 months is not unusual. Treatment length will vary depending on the severity, and there are some cases of TTS that are just too chronic, in which case there are very few treatment options other than invasive surgery. If this is the case for your TTS condition, please make sure you are fully informed about the risks and rewards of TTS corrective surgery.

BFST™ - Using Your Body's Natural Healing System

Your body can heal itself! In fact, your body starts healing itself the moment you are injured and it's the blood in your body that makes it all happen. Your blood is the transport mechanism for everything that is good inside you. It carries oxygen, nutrients, water and antibodies. Proper blood flow is essential to healing. Unfortunately, when you injure your body you stop moving and the swelling sets in. That means your vital blood flow can be reduced to a trickle! If you want to heal quickly, you need to keep your blood moving and that's where Blood Flow Stimulation Therapy™, or BFST™, comes in.

Blood Flow Stimulation Therapy™ promotes the flow of blood through the injured area without the need to exercise your already damaged tissue. You can really feel it work. Within moments of applying an Inferno Wrap™ you can feel the healing sensation and the increase in blood flow. During a treatment, and for quite some time after you finish, your injured area will experience increased blood flow even though your body is at rest. It's a soothing sensation and extremely effective. With BFST™ your injury is constantly being fed with healing, nutritious, oxygen and energy filled blood. This is exactly what your body needs to heal.

Inferno Wraps™ have been specifically designed for the treatment of deep, soft tissue injury. Inferno Wraps contain a patented Energy Web™ which is flexible and shaped to conform to your body. This Energy Web™ emits a uniform wave of perfectly safe electro-magnetic energy over its entire surface. This energy travels deep inside your body and stimulates the blood flow needed to heal your injury.

If you suffer from mild inflammation or pain after certain activities or movements use ultrasound therapy when you complete the activity and then rest and elevate your area of injury. Limit the application of ultrasound to a couple of treatments per day (the manual will recommend treatment frequency depending upon the injury). In between ultrasound treatments, maximize your pain relief and injury recovery by using the Inferno Wrap™ Personal Therapy System. When you're on the go, and not near an electrical outlet, take advantage of the "wear anywhere" concept of our hot/cold wraps - the highest rated wraps in the industry.
