Overview The Achilles tendon is the largest tendon in the body; connecting the calf muscles to the heel. An Achilles tendon rupture prevents the tendon from performing its function of pulling the foot and ankle downward during walking, running and jumping. Most ruptures occur about four to six inches above the heel, but the tendon can also tear where it meets the heel bone. Causes The causes of an Achilles tendon rupture are very similar to Achilles tendinitis. Causes include. Running uphill. Running on a hard surface. Quickly changing speeds from walking to running. Playing sports that cause you to quickly start and stop. Symptoms If you rupture your Achilles tendon, you may hear a snapping or popping sound when it happens. You will feel a sudden and sharp pain in your heel or calf (lower leg). It might feel like you have been kicked or hit in the back of your leg. You may also have swelling in your calf. be unable to put your full weight on your ankle, be unable to stand on tiptoe, or climb stairs, have bruising around the area. If you have any of these symptoms and believe you have ruptured your Achilles tendon, go straight to accident and emergency at your local hospital. If you partially rupture your Achilles tendon, the tear may only be small. Symptoms of pain and stiffness may come on quite suddenly like a complete rupture, but may settle over a few days. Diagnosis To diagnose an Achilles tendon injury, your health care provider will give you a thorough physical exam. He or she may want to see you walk or run to look for problems that might have contributed to your Achilles tendon injury. Non Surgical Treatment Nonsurgical treatment involves extended casting, special braces, orthotics, and physical therapy. Avoids the normal complications and expenses of surgery. Some studies show the outcome is similar to surgery in regard to strength and function. There is risk of an over-lengthened tendon with inadequate tension. Extended immobilization can lead to more muscle weakness. Nonsurgical treatment has a higher incidence of re-rupture than surgical repair. Nonsurgical treatment is often used for nonathletes or for those with a general low level of physical activity who would not benefit from surgery. The elderly and those with complicating medical conditions should also consider conservative nonsurgical treatment. Surgical Treatment Unlike other diseases of the Achilles tendon such as tendonitis or bursitis, Achilles tendon rupture is usually treated with surgical repair. The surgery consists of making a small incision in the back part of the leg, and using sutures to re-attach the two ends of the ruptured tendon. Depending on the condition of the ends of the ruptured tendon and the amount of separation, the surgeon may use other tendons to reinforce the repair. After the surgery, the leg will be immobilized for 6-8 weeks in a walking boot, cast, brace, or splint. Following this time period, patients work with a physical therapist to gradually regain their range of motion and strength. Return to full activity can take quite a long time, usually between 6 months and 1 year. Prevention To prevent Achilles tendonitis or rupture, the following tips are recommended. Avoid activities that place an enormous stress on the heel (for example, uphill running or excessive jumping). Stop all activity if there is pain at the back of the heel. If pain resumes with one particular exercise, another exercise should be selected. Wear proper shoes. Gradually strengthen calf muscles with sit-ups if prior episodes of Achilles tendonitis have occurred. Always warm up with stretching exercises before any activity. Avoid high-impact sports if prior episodes of Achilles tendon injury.
