What Could We Do About Achilles Tendinitis
Overview
You can feel your Achilles tendon beneath the skin on the back of your ankle. It is a fibrous band of tissue that connects your calf muscles to your heel bone (calcaneus), which allows you to lift your heel off the ground. Most commonly an overuse injury, the term Achilles tendinitis commonly refers to, acute inflammation in the sheath surrounding your tendon, chronic damage to the tendon itself, called tendinosis, a combination of the two. Achilles tendinitis can range from mild inflammation to, in rare cases, a tendon rupture. One type of tendinitis, called insertional Achilles tendinitis, can affect the end of the tendon where it attaches to your heel bone. Achilles tendinitis also can be associated with other foot problems, such as painful flat feet.
Causes
Possible factors leading to the development of Achilles tendonitis include the following. Implementing a new exercise regiment such as running uphill or climbing stairs. Change in exercise routine, boosting intensity or increasing duration. Shoes worn during exercise lack support, either because the soles are worn out or poor shoe design. Omitting proper warm-up prior to strenuous exercise. Running on a hard or uneven surface. Deformation in foot such as a flat arch, or any anatomic variation that puts unnecessary strain on the Achilles tendon.
Symptoms
Achilles tendonitis is an injury that occurs when your Achilles tendon -- the large band of tissues connecting the muscles in the back of your lower leg to your heel bone -- becomes inflamed or irritated. The signs and symptoms of Achilles tendonitis often develop gradually. You'll feel pain and stiffness in your Achilles, especially when you first get out of bed. The pain lessens as you warm up, and may even disappear as you continue running. Once you stop, the pain returns and may feel even worse. You may also notice a crackling or creaking sound when you touch or move your Achilles tendon.
Diagnosis
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, 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.
Nonsurgical Treatment
The main treatments for Achilles tendinitis do not involve surgery. It is important to remember that it may take at least 2 to 3 months for the pain to go away. Try putting ice over the Achilles tendon for 15 to 20 minutes, two to three times per day. Remove the ice if the area gets numb. Changes in activity may help manage the symptoms. Decrease or stop any activity that causes you pain. Run or walk on smoother and softer surfaces. Switch to biking, swimming, or other activities that put less stress on the Achilles tendon. Your health care provider or physical therapist can show you stretching exercises for the Achilles tendon. They may also suggest the following changes in your footwear, a brace or boot or cast to keep the heel and tendon still and allow the swelling to go down, heel lifts placed in the shoe under the heel, shoes that are softer in the areas over and under the heel cushion. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen can help with pain or swelling. Talk with your health care provider. If these treatments do not improve symptoms, you may need surgery to remove inflamed tissue and abnormal areas of the tendon. Surgery also can be used to remove the bone spur that is irritating the tendon. Extracorporeal shock wave therapy (ESWT) may be an alternative to surgery for people who have not responded to other treatments. This treatment uses low-dose sound waves.
Surgical Treatment
If several months of more-conservative treatments don't work or if the tendon has torn, your doctor may suggest surgery to repair your Achilles tendon.
Prevention
Maintaining strength and flexibility in the muscles of the calf will help reduce the risk of tendinitis. Overusing a weak or tight Achilles tendon makes you more likely to develop tendinitis.
