Achilles Tendon Tear
The Achilles tendon is the largest tendon in the body. It is formed by the merging together of the upper calf muscles and inserts into the back of the heel bone. Its blood supply comes from the muscles above and the bony attachment below. The blood supply is limited at the ?watershed? zone approximately 1 to 4 inches above the insertion into the heel bone. Paratendonitis and tendinosis develop in the same area. Achilles tendinitis implies an inflammatory response, but this is very limited because there is little blood supply to the Achilles tendon. More appropriate descriptions are inflammation of the surrounding sheath (paratenonitis), degeneration within the substance of the tendon (tendinosis) or a combination of the two.
Achilles tendinitis is usually caused by straining the Achilles tendon through intense activity or a sudden increase in exercise. Individuals who play basketball often develop Achilles tendinitis as a result of pivoting, jumping, and running. These repetitive movements put pressure on the tendon and can gradually wear it down over time. Increasing the intensity of your workouts may also lead to the development of Achilles tendinitis. This is commonly seen in long distance runners who do quite a bit of uphill running. Similarly, if you start exercising more frequently you may also develop the condition due to overuse of the tendon. Not stretching properly before exercise can also make the tendon more prone to injury. Achilles tendinitis is also common in individuals whose feet have a flattened arch, as this places more stress on the tendon. The condition can also be triggered by arthritis, as joint pain can cause one to compensate by putting more pressure on the Achilles tendon.
People with Achilles tendinitis may experience pain during and after exercising. Running and jumping activities become painful and difficult. Symptoms include stiffness and pain in the back of the ankle when pushing off the ball of the foot. For patients with chronic tendinitis (longer than six weeks), x-rays may reveal calcification (hardening of the tissue) in the tendon. Chronic tendinitis can result in a breakdown of the tendon, or tendinosis, which weakens the tendon and may cause a rupture.
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.
Achilles tendonitis should never be self-treated because of the potential for permanent damage to the tendon. While you are waiting to see your doctor, however, some patients have found relief from symptoms with the use of Silipos Achilles Heel Guard during the day and a Night Splint at night. A topical pain reliever like BioFreeze Cold Therapy can provide temporary relief of pain. Achilles tendonitis only gets worse with time.
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.
You can take measures to reduce your risk of developing Achilles Tendinitis. This includes, Increasing your activity level gradually, choosing your shoes carefully, daily stretching and doing exercises to strengthen your calf muscles. As well, applying a small amount ZAX?s Original Heelspur Cream onto your Achilles tendon before and after exercise.
