The Achilles tendon camera.gif connects the calf muscle to the heel bone. It lets you rise up on your toes and push off when you walk or run. The two main problems are, Achilles tendinopathy. This includes one of two conditions, Tendinitis. This actually means "inflammation of the tendon." But inflammation is rarely the cause of tendon pain. Tendinosis. This refers to tiny tears (microtears) in the tissue in and around the tendon. These tears are caused by overuse. In most cases, Achilles tendon pain is the result of tendinosis, not tendinitis. Some experts now use the term tendinopathy to include both inflammation and microtears. But many doctors may still use the term tendinitis to describe a tendon injury. Problems with the Achilles tendon may seem to happen suddenly. But usually they are the result of many tiny tears in the tendon that have happened over time. Achilles tendinopathy is likely to occur in men older than 30. Most Achilles tendon ruptures occur in people 30 to 50 years old who are recreational athletes ("weekend warriors"). Ruptures can also happen in older adults.
Tight or tired calf muscles, which transfer too much of the force associated with running onto the Achilles tendon. Not stretching the calves properly or a rapid increase in intensity and frequency of sport training can make calf muscles fatigued. Activities which place a lot of stress on the achilles tendon, such as hill running and sprint training, can also cause Achilles Tendinitis. Runners who overpronate (roll too far inward on their feet during impact) are most susceptible to Achilles Tendinitis. Runners with flat feet are susceptible to Achilles Tendinitis because flat feet cause a 'wringing out' effect on the achilles tendon during running. High arched feet usually absorb less shock from the impact of running so that shock is transferred to the Achilles tendon. Use of inappropriate footwear when playing sport or running e.g., sandals, can also put an extra load on the Achilles tendon. Shoes are now available that have been designed for individual sports and provide cushioning to absorb the shock of impact and support for the foot during forceful movements. Training on hard surfaces e.g., concrete, also increases the risk of Achilles Tendinitis. Landing heavily or continuously on a hard surface can send a shock through the body which is partly absorbed by the Achilles tendon. A soft surface like grass turf helps to lessen the shock of the impact by absorbing some of the force of the feet landing heavily on the ground after a jump or during a running motion.
Symptoms of Achilles tendinitis and tendinosis include recurring localized heel pain, sometimes severe, along the achilles tendon during or after exercise. Pain often begins after exercise and gradually worsens. Morning tenderness or stiffness about an inch and a half above the point where the Achilles tendon is attached to the heel bone. Sluggishness in your leg. Mild to severe swelling. Stiffness that generally diminishes as the tendon warms up with use.
On examination, an inflamed or partially torn Achilles tendon is tender when squeezed between the fingers. Complete tears are differentiated by sudden, severe pain and inability to walk on the extremity. A palpable defect along the course of the tendon. A positive Thompson test (while the patient lies prone on the examination table, the examiner squeezes the calf muscle; this maneuver by the examiner does not cause the normally expected plantar flexion of the foot).
Make sure that the tendon is not torn through and through. If it is severed, you must see a doctor immediately so that the tendon can be repaired. Severe injuries can sever a tendon, without a skin laceration being present. Testing involves moving the toes and foot to see if the tendon moves. If the tendon does not appear to move, it may be severed (comparing the injured tendon and its movement to the same tendon on the uninjured foot may help). Very sharp pain, a sudden pop, or an obvious gap in the structure of the tendon are all signs of a rupture, and should be seen by a doctor as soon as possible. If there is extreme swelling of the leg, and pain (out of proportion to the amount of trauma received), you may have sustained a vascular injury. A doctor must see this type of injury immediately. If you are not sure, see a doctor. If you have multiple injured areas see a doctor immediately, in order to prevent excessive swelling and pain. If the above exam is negative, then you may proceed with self-treatment. (However, if you are not sure of the extent of your injury, you should consult your doctor immediately). The sooner you begin to treat your injury by following "R.I.C.E.", the better you will feel. Rest is very important. Take off your shoe, get off your feet, and relax. Ice should be applied as soon as possible. Never apply ice directly on the injured area, as the cold may make the pain worse. Ice should be applied close to the injured site, between the heart and the injury, so that as the blood flows under the ice, it will be cooled. This cool blood flowing into the injured area will help to reduce the swelling and pain. Apply the ice, wrapped in a cloth or over an elastic bandage, to the foot for 15 minutes, every 1-2 hours, for up to 3 days after an injury. If the ice is uncomfortable, or causes increased pain, do not continue to use it, and see a doctor. If you have poor circulation do not use ice, as this may cause a serious problem. c. Compression is used to limit swelling, and to give support to the injured area. Compression should be applied to the entire foot, starting first at the toes and working back to the ankle. If it is applied just to the injured area, increased swelling will occur in front and behind the wrapping. Compression should be applied with a 3-inch elastic bandage, beginning around the base of all the toes, and then going around the foot and ankle. Continue over the calf muscle when possible. Compression reduces motion in the injured area and foot, and this decreases the pain, and allows for quicker healing. The bandage should not be so tight that it causes increased pain or throbbing in the toes or foot. It should be comfortable! Do not remove the elastic bandage for the first 12 hours, unless it becomes too tight, or the pain increases, or the toes become pale, blue, or cool. If any of these things happen, immediately remove all bandages, and leave them off for several hours. The normal color and temperature of the toes should return immediately. If not, see a doctor immediately! Continue until the swelling and pain subsides; it could take from several days to several weeks. d. Elevation of the leg will aid in reducing swelling and pain. Blood rushes to an injured area to bring increased blood cells, that aid in healing. Gravity will also force blood to the injured area. Too many cells and too much fluid will apply pressure to the injured nerves and tissues, and cause increased pain and delayed healing. Keep your foot elevated so that it is at least parallel to the ground, or higher if it is comfortable. Do this for at least 48 hours, or until the throbbing subsides, when you lower the leg.
Mini-Open Achilles Tendon Repair. During a mini-open Achilles tendon repair surgery, 2 to 8 small stab incisions are made to pull the edges of the tendon tear together and suture the torn edges to repair the damage. During this procedure the surgeon will make one 3 to 4 cm long incision on the back of your ankle and 2 to 4 smaller vertical incisions around the long incision. These smaller veritical incisions are made with a pair of surgical scissors and are commonly referred to as "stab incisions". Once the incisions are opened up, the surgeon will place precise sutures with non-absorbable stitches to strengthen the damaged Achilles tendon tissue. This suturing technique reduces the amount of scar tissue on the tendon after surgery and provides better surface healing of the skin. Unlike the traditional method of an open surgery, this procedure has less risks and complications involved. To learn about all risks you may face be sure to speak to your doctor.
Regardless of whether the Achilles injury is insertional or non-insertional, a great method for lessening stress on the Achilles tendon is flexor digitorum longus exercises. This muscle, which originates along the back of the leg and attaches to the tips of the toes, lies deep to the Achilles. It works synergistically with the soleus muscle to decelerate the forward motion of the leg before the heel leaves the ground during propulsion. This significantly lessens strain on the Achilles tendon as it decelerates elongation of the tendon. Many foot surgeons are aware of the connection between flexor digitorum longus and the Achilles tendon-surgical lengthening of the Achilles (which is done to treat certain congenital problems) almost always results in developing hammer toes as flexor digitorum longus attempts to do the job of the recently lengthened tendon. Finally, avoid having cortisone injected into either the bursa or tendon-doing so weakens the tendon as it shifts production of collagen from type one to type three. In a recent study published in the Journal of Bone Joint Surgery(9), cortisone was shown to lower the stress necessary to rupture the Achilles tendon, and was particularly dangerous when done on both sides, as it produced a systemic effect that further weakened the tendon.
