Which are the Main Treatments And Causes Of Achilles Tendinitis
Overview
Achilles tendonitis is an inflammation of the Achilles tendon, which attaches the calf muscles (gastrocnemius and soleus) to the heel bone (calcaneus). Pain can be felt on the back of the heel at the attachment of the tendon, along the length of the tendon, or at the base of the calf where the tendon attaches to the muscle. Swelling is not always present with this injury, but it may occur in severe cases.
Causes
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.
Symptoms
The most common site of Achilles Tendonitis is at the heel to 4 inches above the heel. The diagnosis of this problem is made when the following signs are present. Pain in the Achilles tendon with up and down movement of the foot at the ankle. Pain in the Achilles tendon when you squeeze the tendon from side to side. If you are unable to move the foot either up or down, or you have intense pain when trying to walk, you may have a tear of the Achilles tendon, and you should see a doctor immediately. Also if you have severe pain in the calf, with or without discolorations of the skin, you may have a blood clot, and this is a medical emergency; see a doctor immediately. If you do not fall into either of these categories then try the following suggestions.
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
When the tendon tears or ruptures the variety of surgical techniques are available to repair the damage and restore the tendons function. Recent research that is done at Emory University Department of orthopedics have perfected the repair of the Achilles tendon. The procedure is generally involves making an incision in the back of your leg and stitching the torn tendon together using a technique developed and tested by Dr. Labib. Depending on the condition of the torn tissue the repair may be reinforced with other tendons.
Prevention
Your podiatrist will work with you to decrease your chances of re-developing tendinitis. He or she may create custom orthotics to help control the motion of your feet. He or she may also recommend certain stretches or exercises to increase the tendon's elasticity and strengthen the muscles attached to the tendon. Gradually increasing your activity level with an appropriate training schedule-building up to a 5K run, for instance, instead of simply tackling the whole course the first day-can also help prevent tendinitis.
