Overview<br>The Achilles tendon, which connects the calf muscles to the heel bone, can withstand significant pressure from physical activities. Achilles tendinitis is estimated to account for approximately 11 percent of all running injuries, as the Achilles tendon provides the momentum to push off to walk or run. Achilles tendinitis, also called Achilles tendinopathy, results from overuse, injury or disease of the Achilles tendon, which causes the area to become inflamed. There are two types of Achilles tendinitis: Non-insertional Achilles Tendinitis - Fibers that are located in the middle portion of the tendon began to develop small tears that cause swelling and thickening. This type of tendinitis is usually found in younger people who are very active. Insertional Achilles Tendinitis - Develops where the tendon attaches to the heel bone in the lower part of the heel. Extra bone growth also called bone spurs form because of this tendinitis and can affect patients at any time, even if they are not active.<br><br>Causes<br>Achilles tendonitis is an overuse injury. Too much too soon is the common cause of overuse injuries, however other factors can contribute to developing the condition. An increase in activity, either distance, speed or a sudden change to running up hills. As a rule of thumb distance runners should increase their mileage by no more than 10% per week. A change of footwear or training surface for example suddenly running on soft sand can cause the heel to drop lower than normal making the tendon stretch further than it is used to. Weak calf muscles can tighten or go into partial spasm which again increases the strain on the achilles tendon by shortening the muscle. Running up hills - the achilles tendon has to stretch more than normal on every stride. This is fine for a while but will mean the tendon will fatigue sooner than normal. Overpronation or feet which roll in when running can place an increased strain on the achilles tendon. As the foot rolls in (flattens) the lower leg also rotates inwards which places twisting stresses on the tendon. Wearing high heels constantly shortens the tendon and calf muscles. When exercising in flat running shoes, the tendon is stretched beyond its normal range which places an abnormal strain on the tendon.<br><br>Symptoms<br>People with Achilles tendinitis may experience pain during and after exercising. Running and jumping activities become painful and difficult. Symptoms include stiffness and pain in the back of the ankle when pushing off the ball of the foot. For patients with chronic tendinitis (longer than six weeks), x-rays may reveal calcification (hardening of the tissue) in the tendon. Chronic tendinitis can result in a breakdown of the tendon, or tendinosis, which weakens the tendon and may cause a rupture.<br><br>Diagnosis<br>A podiatrist can usually make the diagnosis by clinical history and physical examination alone. Pain with touching or stretching the tendon is typical. There may also be a visible swelling to the tendon. The patient frequently has difficulty plantarflexing (pushing down the ball of the foot and toes, like one would press on a gas pedal), particularly against resistance. In most cases X-rays don't show much, as they tend to show bone more than soft tissues. But X-rays may show associated degeneration of the heel bone that is common with Achilles Tendon problems. For example, [http://CathyLoone.bravesites.com/ heel spurs], calcification within the tendon, avulsion fractures, periostitis (a bruising of the outer covering of the bone) may all be seen on X-ray. In cases where we are uncertain as to the extent of the damage to the tendon, though, an MRI scan may be necessary, which images the soft tissues better than X-rays. When the tendon is simply inflamed and not severely damaged, the problem may or may not be visible on MRI. It depends upon the severity of the condition.<br><br>Nonsurgical Treatment<br>NSAIDs help decrease swelling and pain or fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions. Steroid injections. Steroids decrease pain and swelling. After you get this shot, you may feel like your Achilles tendon is healed. Do not return to your regular exercise until your caregiver says it is okay. You could make the tendinitis worse, or even tear the tendon. Surgery. If your tendinitis does not heal with other treatments, you may need surgery. Surgery may be done to repair a tear in the tendon, or to remove parts of the tendon. The most important way to manage Achilles tendinitis is to rest. Rest decreases swelling and keeps your tendinitis from getting worse. You may feel pain when you begin to run or exercise. The pain usually goes away as your muscles warm up, but it may come back. Your caregiver may tell you to stop your usual training or exercise activities. He may give you other exercises to do until your Achilles tendon heals. Ice decreases swelling and pain. Put ice in a plastic bag. Cover it with a towel. Put this on your Achilles tendon for 15 to 20 minutes, 3 to 4 times each day. Do this for 2 to 3 days or until the pain goes away. After 2 or 3 days, you may use heat to decrease pain and stiffness. Use a hot water bottle, heating pad, whirlpool, or warm compress. To make a compress, soak a clean washcloth in warm water. Wring out the extra water and put it on your Achilles tendon 15 to 20 minutes, 3 to 4 times each day. Stretching and making the muscles stronger may help decrease stress on your Achilles tendon. Physical therapists can teach you exercises and treatments to help your tendinitis heal faster. You may need to wear inserts in your shoes. You may need to wrap tape around your heel and back of the leg. You may need to wear a cast, brace, or support boot.<br><br><br><br>Surgical Treatment<br>Surgery is considered the last resort. It is only recommended if all other treatment options have failed after at least six months. In this situation, badly damaged portions of the tendon may be removed. If the tendon has ruptured, surgery is necessary to re-attach the tendon. Rehabilitation, including stretching and strength exercises, is started soon after the surgery. In most cases, normal activities can be resumed after about 10 weeks. Return to competitive sport for some people may be delayed for about three to six months.<br><br>Prevention<br>Warm up slowly by running at least one minute per mile slower than your usual pace for the first mile. Running backwards during your first mile is also a very effective way to warm up the Achilles, because doing so produces a gentle eccentric load that acts to strengthen the tendon. Runners should also avoid making sudden changes in mileage, and they should be particularly careful when wearing racing flats, as these shoes produce very rapid rates of pronation that increase the risk of Achilles tendon injury. If you have a tendency to be stiff, spend extra time stretching. If you?re overly flexible, perform eccentric load exercises preventively. Lastly, it is always important to control biomechanical alignment issues, either with proper running shoes and if necessary, stock or custom orthotics.
