The Achilles tendon connects the calf muscle to the back of the heel. Injuries to the Achilles tendon are common, as it is in constant use during walking and running. These injuries, known as Achilles tendinitis, are usually the result of overuse damage and minor tears that have accumulated over years. Your risk of developing Achilles tendinitis increases with age and activity level. Many athletes develop Achilles tendinitis. The tendon may be injured several inches away from where it attaches to the foot or at the point of attachment. An injury at the point of attachment is called Achilles enthesopathy. We recommend a combination of treatments over a period of months that may include wearing supportive shoes or orthotic devices, performing stretching exercises, and icing the affected area. If these treatments are not effective, or if the tendon is completely torn, we may recommend surgery.
Achilles tendonitis is an overuse injury that is common especially to joggers and jumpers, due to the repetitive action and so may occur in other activities that requires the same repetitive action. Most tendon injuries are the result of gradual wear and tear to the tendon from overuse or ageing. Anyone can have a tendon injury, but people who make the same motions over and over in their jobs, sports, or daily activities are more likely to damage a tendon. A tendon injury can happen suddenly or little by little. You are more likely to have a sudden injury if the tendon has been weakened over time. Common causes of Achilles tendonitis include, over-training or unaccustomed use,?too much too soon?. Sudden change in training surface e.g. grass to bitumen. Flat (over-pronated) feet, High foot arch with tight Achilles tendon. tight hamstring (back of thigh) and calf muscles, toe walking (or constantly wearing high heels). Poorly supportive footwear, hill running. Poor eccentric strength.
The pain associated with Achilles tendinitis typically begins as a mild ache in the back of the leg or above the heel after running or other sports activity. Episodes of more severe pain may occur after prolonged running, stair climbing or sprinting. You might also experience tenderness or stiffness, especially in the morning, which usually improves with mild activity. If you experience persistent pain around the Achilles tendon, call your doctor. Seek immediate medical attention if the pain or disability is severe. You may have a torn (ruptured) Achilles tendon.
When diagnosing Achilles tendinitis, a doctor will ask the patient a few questions about their symptoms and then perform a physical examination. To perform a physical exam on the Achilles tendon, the doctor will lightly touch around the back of the ankle and tendon to locate the source of the pain or inflammation. They will also test the foot and ankle to see if their range of motion and flexibility has been impaired. The doctor might also order an imaging test to be done on the tendon. This will aid in the elimination of other possible causes of pain and swelling, and may help the doctor assess the level of damage (if any) that has been done to the tendon. Types of imaging tests that could be used for diagnosing Achilles tendinitis are MRI (Magnetic resonance imaging), X-ray, Ultrasound.
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.
Surgery for an Achilles tendon rupture can be done with a single large incision, which is called open surgery. Or it can be done with several small incisions. This is called percutaneous surgery. The differences in age and activity levels of people who get surgery can make it hard to know if Achilles tendon surgery is effective. The success of your surgery can depend on, your surgeon’s experience. The type of surgery you have. How damaged the tendon is. How soon after rupture the surgery is done. How soon you start your rehab program after surgery. How well you follow your rehab program. Talk to your surgeon about his or her surgical experience. Ask about his or her success rate with the technique that would best treat your condition.
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.
