The Achilles tendon attaches the calf
muscle to the heel bone. Jumping, climbing and strenuous exercise can strain the tendon and calf muscle, which can cause the type of inflammation known as tendinitis. This injury can be mild enough
that it can be treated by over-the-counter medications or so severe that it must be repaired surgically. Chronic tendinitis can cause microscopic tears in the muscle which can weaken the tendon and
increase the risk for tear or rupture. Symptoms usually include pain and swelling near the ankle. Pain may lead to weakness in the area that increases with walking and running. Stiffness in the
tendon may be worse in the morning.
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.
Paratenonitis presents in younger people. Symptoms start gradually and spontaneously. Aching and burning pain is noted especially with morning activity. It may improve slightly with initial activity,
but becomes worse with further activity. It is aggravated by exercise. Over time less exercise is required to cause the pain. The Achilles tendon is often enlarged, warm and tender approximately 1 to
4 inches above its heel insertion. Sometimes friction is noted with gentle palpation of the tendon during ankle motion. Tendinosis presents similarly but typically in middle-aged people. If severe
pain and limited walking ability are present, it may indicate a partial tear of the tendon.
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.
The initial aim of the treatment in acute cases is to reduce strain on the tendon and reduce inflammation until rehabilitation can begin. This may involve, avoiding or severely limiting activities
that may aggravate the condition, such as running or uphill climbs. Using shoe inserts (orthoses) to take pressure off the tendon. Wear supportive shoes. Reducing Inflammation by icing. Taking
non-steroidal anti-inflammatory drugs. Heel cups and heel lifts can be used temporarily to take pressure off the tendon, but must not be used long term as it can lead to a shortening of the calf.
Calf Compression Sleeves. Placing the foot in a cast or restrictive ankle-boot to minimize movement and give the tendon time to heal. This may be recommended in severe cases and used for about eight
Surgery for an acute Achilles tendon tear is seemingly straightforward. The ends of the torn tendon are surgically exposed and sutures are used to tie the ends together. The sutures used to tie
together the torn tendon ends are thick and strong, and are woven into the Achilles both above and below the tear. While the concepts of surgery are straightforward, the execution is more complex.
Care must be taken to ensure the tendon is repaired with the proper tension -- not too tight or too loose. The skin must be taken care of, as excessive handling of the soft tissues can cause severe
problems including infection and skin necrosis. Nerves are located just adjacent to the tendon, and must be protected to prevent nerve injury. If surgery is decided upon, it is usually performed
within days or weeks of the injury. The idea is to perform the repair before scar tissue has formed, which would make the repair more difficult. Some surgeons may recommend delaying surgery a few
days from the initial injury to allow swelling to subside before proceeding with the repair.
To lower your risk of Achilles tendonitis, stretch your calf muscles. Stretching at the beginning of each day will improve your agility and make you less prone to injury. You should also try to
stretch both before and after workouts. To stretch your Achilles, stand with a straight leg, and lean forward as you keep your heel on the ground. If this is painful, be sure to check with a doctor.
It is always a good idea to talk to your doctor before starting a new exercise routine. Whenever you begin a new fitness regimen, it is a good idea to set incremental goals. Gradually intensifying
your physical activity is less likely to cause injury. Limiting sudden movements that jolt the heels and calves also helps to reduce the risk of Achilles tendonitis. Try combining both high- and
low-impact exercises in your workouts to reduce stress on the tendon. For example, playing basketball can be combined with swimming. It doesn?t matter if you?re walking, running, or just hanging out.
To decrease pressure on your calves and Achilles tendon, it?s important to always wear the right shoes. That means choosing shoes with proper cushioning and arch support. If you?ve worn a pair of
shoes for a long time, consider replacing them or using arch supports. Some women feel pain in the Achilles tendon when switching from high heels to flats. Daily wearing of high heels can both
tighten and shorten the Achilles tendon. Wearing flats causes additional bending in the foot. This can be painful for the high-heel wearer who is not accustomed to the resulting flexion. One
effective strategy is to reduce the heel size of shoes gradually. This allows the tendon to slowly stretch and increase its range of motion.
