Causes And Treatment Of Achilles Tendon Pain

Overview
Achilles-tendinitis is characterized by inflammation and pain at the Achilles tendon (back of the ankle). This tendon, sometimes called the heel cord, is the tendon attachment of the calf muscles from the leg and knee to the heel. This structure is important in standing on your toes or in the pushing-off phase of walking, running, or jumping.Achilles-tendinitis is usually a grade 1 or 2 strain of the tendon. A grade 1 strain is a mild strain. There is a slight pull of the tendon without obvious tendon tearing. (There is microscopic tendon tearing.) There is no loss of strength, and the tendon is the correct length. A grade 2 strain is a moderate strain. There is tearing of tendon fibers within the substance of the tendon or where the tendon attaches to muscle or bone. The length of the tendon or whole muscle-tendon-bone unit is increased, and there is usually decreased strength. A grade 3 strain is a complete 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
Common symptoms of Achilles tendinitis include, pain and stiffness along the Achilles tendon in the morning, pain along the tendon or back of the heel that worsens with activity, Severe pain the day after exercising, thickening of the tendon, bone spur (insertional tendinitis) swelling that is present all the time and gets worse throughout the day with activity, If you have experienced a sudden "pop" in the back of your calf or heel, you may have ruptured (torn) your Achilles tendon. See your doctor immediately if you think you may have torn your 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
Treatment approaches for Achilles tendonitis or tendonosis are selected on the basis of how long the injury has been present and the degree of damage to the tendon. In the early stage, when there is sudden (acute) inflammation, one or more of the following options may be recommended. Immobilization. Immobilization may involve the use of a cast or removable walking boot to reduce forces through the Achilles tendon and promote healing. Ice. To reduce swelling due to inflammation, apply a bag of ice over a thin towel to the affected area for 20 minutes of each waking hour. Do not put ice directly against the skin. Oral medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be helpful in reducing the pain and inflammation in the early stage of the condition. Orthotics. For those with over-pronation or gait abnormalities, custom orthotic devices may be prescribed. Night splints. Night splints help to maintain a stretch in the Achilles tendon during sleep. Physical therapy. Physical therapy may include strengthening exercises, soft-tissue massage/mobilization, gait and running re-education, stretching, and ultrasound therapy.



Surgical Treatment
Surgery should be considered to relieve Achilles tendinitis only if the pain does not improve after 6 months of nonsurgical treatment. The specific type of surgery depends on the location of the tendinitis and the amount of damage to the tendon. Gastrocnemius recession. This is a surgical lengthening of the calf (gastrocnemius) muscles. Because tight calf muscles place increased stress on the Achilles tendon, this procedure is useful for patients who still have difficulty flexing their feet, despite consistent stretching. In gastrocnemius recession, one of the two muscles that make up the calf is lengthened to increase the motion of the ankle. The procedure can be performed with a traditional, open incision or with a smaller incision and an endoscope-an instrument that contains a small camera. Your doctor will discuss the procedure that best meets your needs. Complication rates for gastrocnemius recession are low, but can include nerve damage. Gastrocnemius recession can be performed with or without d?bridement, which is removal of damaged tissue. D?bridement and repair (tendon has less than 50% damage). The goal of this operation is to remove the damaged part of the Achilles tendon. Once the unhealthy portion of the tendon has been removed, the remaining tendon is repaired with sutures, or stitches to complete the repair. In insertional tendinitis, the bone spur is also removed. Repair of the tendon in these instances may require the use of metal or plastic anchors to help hold the Achilles tendon to the heel bone, where it attaches. After d?bridement and repair, most patients are allowed to walk in a removable boot or cast within 2 weeks, although this period depends upon the amount of damage to the tendon. D?bridement with tendon transfer (tendon has greater than 50% damage). In cases where more than 50% of the Achilles tendon is not healthy and requires removal, the remaining portion of the tendon is not strong enough to function alone. To prevent the remaining tendon from rupturing with activity, an Achilles tendon transfer is performed. The tendon that helps the big toe point down is moved to the heel bone to add strength to the damaged tendon. Although this sounds severe, the big toe will still be able to move, and most patients will not notice a change in the way they walk or run. Depending on the extent of damage to the tendon, some patients may not be able to return to competitive sports or running. Recovery. Most patients have good results from surgery. The main factor in surgical recovery is the amount of damage to the tendon. The greater the amount of tendon involved, the longer the recovery period, and the less likely a patient will be able to return to sports activity. Physical therapy is an important part of recovery. Many patients require 12 months of rehabilitation before they are pain-free.

Prevention
Appropriately warm up and stretch before practice or competition. Allow time for adequate rest and recovery between practices and competition. Maintain appropriate conditioning, Ankle and leg flexibility, Muscle strength and endurance, Cardiovascular fitness. Use proper technique. To help prevent recurrence, taping, protective strapping, or an adhesive bandage may be recommended for several weeks after healing is complete.
