The Main Causes And Treatment Methods For Achilles Tendonitis
Overview
Achilles tendonitis is an inflammation of the Achilles tendon. This inflammation is typically short-lived. Over time, if not resolved, the condition may progress to a degeneration of the tendon (Achilles tendonosis), in which the tendon loses its organized structure and is likely to develop microscopic tears. Sometimes the degeneration involves the site where the Achilles tendon attaches to the heel bone. In rare cases, chronic degeneration with or without pain may result in rupture of the tendon.
Causes
Short of a trauma, the primary cause of Achilles tendonitis is when the calf muscle is so tight that the heel is unable to come down to the ground placing extreme stress on the Achilles tendon at the insertion. Keep in mind that the calf muscle is designed to contract up, lifting the heel bone off the ground, propelling you forwards to the front of the foot for push off. When the calf is so tight that the heel is prevented from coming down on the ground there will be stress on the tendon and the foot will over pronate causing the Achilles tendon to twist, adding to the stress on the insertion. Improper treatment may lead to a more severe injury, such as a rupture or chronic weakening, which may require surgery.
Symptoms
The onset of the symptoms of Achilles tendonitis tend to be gradual, with symptoms usually developing over a period of several days, or even weeks. Symptoms may include, Pain, this may be mild at first and may only be noticeable after exercise. Over time the pain may become constant and severe. Stiffness, this is usually relieved by activity. Sluggishness in the leg. Tenderness, particularly in the morning and most commonly felt just above where the tendon attaches to the heel bone. Swelling.
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
There is insufficient evidence from randomised controlled trials to determine which method of treatment is the most appropriate for the treatment of acute or chronic Achilles tendonitis. The patient should abstain from aggravating activities, but with a minimum of rest in order to preserve overall fitness. Possible treatments are non-steroidal anti-inflammatory drugs (NSAIDs), ice, rest, increased warm-up/stretching exercises, physiotherapy and heel lifts (orthotic devices - used on both sides to prevent a gait imbalance). Other treatments evaluated in a Cochrane review were heparin, steroid injections, glycosaminoglycan sulfate, Actovegin?, and topical laser treatment. There was no clear evidence of benefit from these. Casting is an option for resistant Achilles tendonitis. Drugs - analgesics and NSAIDs. Surgery is sometimes used for resistant Achilles tendonitis, but usually as a last resort. Other recently reported treatments include continuing sporting activity in conjunction with rehabilitation, low-energy shock wave therapy[4] and topical glyceryl trinitrate .
Surgical Treatment
Occasionally, conservative management of Achilles tendon conditions fails. This failure is more common in older male patients and those with longstanding symptoms, those who persist in full training despite symptoms or those who have uncorrected predisposing factors. In these cases, surgery may be indicated. It should be remembered, however, that the rehabilitation program, particularly for severe Achilles tendon injuries, is a slow, lengthy program. Surgery is only indicated when there is failure to progress in the rehabilitation program. Surgery should not be considered unless at least six months of appropriate conservative management has failed to lead to improvement.
Prevention
Although Achilles tendinitis cannot be completely prevented, the risk of developing it can be lowered. Being aware of the possible causes does help, but the risk can be greatly reduced by taking the following precautions. Getting a variety of exercise - alternating between high-impact exercises (e.g. running) and low-impact exercise (e.g. swimming) can help, as it means there are days when the Achilles tendon is under less tension. Limit certain exercises - doing too much hill running, for example, can put excessive strain on the Achilles tendon. Wearing the correct shoes and replacing them when worn - making sure they support the arch and protect the heel will create less tension in the tendon. Using arch supports inside the shoe, if the shoe is in good condition but doesn't provide the required arch support this is a cheaper (and possibly more effective) alternative to replacing the shoe completely. Stretching, doing this before and after exercising helps to keep the Achilles tendon flexible, which means less chance of tendinitis developing. There is no harm in stretching every day (even on days of rest), as this will only further improve flexibility. Gradually increasing the intensity of a workout - Achilles tendinitis can occur when the tendon is suddenly put under too much strain, warming up and increasing the level of activity gradually gives your muscles time to loosen up and puts less pressure on the tendon.
