Achilles Tendon Pain Causes And Treatments

Overview

Achilles TendonitisAchilles tendinitis is a common condition that causes pain along the back of the leg near the heel. The Achilles tendon is the largest tendon in the body. It connects your calf muscles to your heel bone and is used when you walk, run, and jump. Although the Achilles tendon can withstand great stresses from running and jumping, it is also prone to tendinitis, a condition associated with overuse and degeneration. Simply defined, tendinitis is inflammation of a tendon. Inflammation is the body’s natural response to injury or disease, and often causes swelling, pain, or irritation. There are two types of Achilles tendinitis, based upon which part of the tendon is inflamed. Noninsertional Achilles tendinitis, Noninsertional Achilles Tendinitis. In noninsertional In both noninsertional and insertional Achilles tendinitis, damaged tendon fibers may also calcify (harden). Tendinitis that affects the insertion of the tendon can occur at any time, even in patients who are not active.

Causes

The calf is under a lot of strain when running: it is not only put on stretch during landing of the foot, but it also has to produce the tension needed to support body weight and absorb the shock of landing. This is what is called an ?eccentric load?. Excessive eccentric loading – either by way of a dramatic increase in mileage, or excessive hill running, or faulty running posture – could very well be the cause of a runner?s achilles tendinitis. The calf strain translates downward into the achilles tendon where it attaches to the heel, and inflammation ensues. Inflammation then causes scarring and fibrosis of tissues, which in turn inflicts pain upon stretching or use. Risk factors for Achilles tendinitis also include spending prolonged amounts of time standing or walking.

Symptoms

Achilles tendinitis symptoms present as mild to severe pain or swelling near the ankle. The pain may lead to weakness and decreased mobility, symptoms that increase gradually while walking or running. Over time, the pain worsens, and stiffness in the tendon may be noted in the morning. Mild activity may provide relief. Physical exam may reveal an audible cracking sound when the Achilles tendon is palpated. The lower leg may exhibit weakness. A ruptured or torn Achilles tendon is severely painful and warrants immediate medical attention. The signs of a ruptured or torn Achilles tendon include. Acute, excruciating pain. Impaired mobility, unable to point the foot downward or walk on the toes. Weight bearing or walking on the affected side is not possible.

Diagnosis

Confirming Achilles tendonitis may involve imaging tests. X-rays provide images of the bones of the foot and leg. Magnetic resonance imaging (MRI) is useful for detecting ruptures and degeneration of tissue. Ultrasound shows tendon movement, related damage, and inflammation.

Nonsurgical Treatment

As with most soft tissue injuries the initial treatment is RICE – Rest, Ice, Compression and Elevation. In the early phase you?ll be unable to walk without a limp, so your Achilles tendon needs some active rest from weight-bearing loads. You may need to be non or partial-weight-bearing, utilise crutches, a wedged achilles walking boot or heel wedges to temporarily relieve some of the pressure on the Achilles tendon. Your physiotherapist will advise you on what they feel is best for you. Ice is a simple and effective modality to reduce your pain and swelling. Please apply for 20-30 minutes each 2 to 4 hours during the initial phase or when you notice that your injury is warm or hot. Anti-inflammatory medication (if tolerated) and natural substances eg arnica may help reduce your pain and swelling. However, it is best to avoid anti-inflammatory drugs during the initial 48 to 72 hours when they may encourage additional bleeding. Most people can tolerate paracetamol as a pain reducing medication. As you improve a kinesio style supportive taping will help to both support the injured soft tissue.

Surgical Treatment

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.

Prevention

Regardless of whether the Achilles injury is insertional or non-insertional, a great method for lessening stress on the Achilles tendon is flexor digitorum longus exercises. This muscle, which originates along the back of the leg and attaches to the tips of the toes, lies deep to the Achilles. It works synergistically with the soleus muscle to decelerate the forward motion of the leg before the heel leaves the ground during propulsion. This significantly lessens strain on the Achilles tendon as it decelerates elongation of the tendon. Many foot surgeons are aware of the connection between flexor digitorum longus and the Achilles tendon-surgical lengthening of the Achilles (which is done to treat certain congenital problems) almost always results in developing hammer toes as flexor digitorum longus attempts to do the job of the recently lengthened tendon. Finally, avoid having cortisone injected into either the bursa or tendon-doing so weakens the tendon as it shifts production of collagen from type one to type three. In a recent study published in the Journal of Bone Joint Surgery(9), cortisone was shown to lower the stress necessary to rupture the Achilles tendon, and was particularly dangerous when done on both sides, as it produced a systemic effect that further weakened the tendon.
