Achilles tendonitis is a condition wherein the Achilles tendon, at or near its insertion to back of the heel, becomes inflamed and causes pain. The Achilles tendon is one of the longest and strongest tendons in the body. It is avascular (not supplied with blood vessels) so it can be slow to heal. The Achilles tendon is formed in the lower third of the leg. Two muscles join to form the Achilles tendon, the Gastrocnemius and the Soleus which are commonly referred to as the calf muscle. The Achilles tendon works as an anti-pronator which means it helps to prevent the foot from rolling inward.
Achilles tendinitis usually results from overuse and not a specific injury or trauma. When the body is subject to repetitive stress, the Achilles tendon is more prone to become inflamed. Other factors may cause Achilles tendinitis, such as, Sudden increase in physical activity, which can be related to distance, speed or hills, without giving yourself adequate time to adjust to the heightened activity. With running up hills, the Achilles tendon has to stretch more for each stride, which creates rapid fatigue. Inadequate footwear or training surface. High heels may cause a problem, because the Achilles tendon and calf muscles are shortened. While exercising in flat, athletic shoes, the tendon is then stretched beyond its normal range, putting abnormal strain on the tendon. Tight calf muscles which gives the foot a decreased range of motion. The strained calf muscles may also put extra strain on the Achilles tendon. Bone spur where the Achilles tendon attaches to the heel bone, aggravating the tendon and causing pain.
Dull or sharp pain anywhere along the back of the tendon, but usually close to the heel. limited ankle flexibility redness or heat over the painful area a nodule (a lumpy build-up of scar tissue) that can be felt on the tendon a cracking sound (scar tissue rubbing against tendon) with ankle movement.
If you think you might have Achilles tendonitis, check in with your doctor before it gets any worse. Your doc will ask about the activities you’ve been doing and will examine your leg, foot, ankle, and knee for range of motion. If your pain is more severe, the doctor may also make sure you haven’t ruptured (torn) your Achilles tendon. To check this, the doc might have you lie face down and bend your knee while he or she presses on your calf muscles to see if your foot flexes. Any flexing of the foot means the tendon is at least partly intact. It’s possible that the doctor might also order an X-ray or MRI scan of your foot and leg to check for fractures, partial tears of the tendon, or signs of a condition that might get worse. Foot and ankle pain also might be a sign of other overuse injuries that can cause foot and heel pain, like plantar fasciitis and Sever’s disease. If you also have any problems like these, they also need to be treated.
With proper care for the area, the pain in the tendon should lessen over three weeks, but it should be noted that the healing of the area continues and doesn’t even peak until at least six weeks following the initial injury. This is due to scar tissue formation, which initially acts like the glue to bond the tissue back together. Scar tissue will continue to form past six weeks in some cases and as long as a year in severe cases. After 6 months this condition is considered chronic and much more difficult to treat. The initial approach to treating Achilles tendonitis is to support and protect the tendons by bracing any areas of the tendon that are being pulled on during use. It is important to loosen up the tendon, lessen the pain, and minimize any inflammation.
There are two types of Achilles repair surgery for tendonitis (inflammation of the Achilles Tendon), if nonsurgical treatments aren’t effective. Gastrocnemius recession – The orthopaedic surgeon lengthens the calf muscles to reduce stress on your Achilles tendon. D?bridement and repair – During this procedure, the surgeon removes the damaged part of the Achilles tendon and repairs the remaining tendon with sutures or stitches. Debridement is done when the tendon has less than 50% damage.
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.
