Overview An Achilles tendon rupture is also known as a rupture of the gastrocnemius tendon, or the common calcanean tendon. The tendon is actually composed of 5 different tendons, the two most important being the superficial digital flexor and gastrocnemius tendons. The gastrocnemius tendon is the largest of these, and is the most powerful extensor of the hock (ankle) joint. Both the superficial digital flexor and gastrocnemius tendons attach to the heel bone, called the calcaneus bone. A rupture of the Achilles tendon may be a partial tear, which means just the gastrocnemius is torn, or a complete tear, in which all five tendons have been torn. (show diagrams, normal anatomy vs partial vs complete tears). Causes Common causes of an Achilles tendon rupture include the progression of or the final result of longstanding Achilles tendonitis or an overuse injury. An injury to the ankle or a direct blow to the Achilles tendon. As a result of a fall where an individual lands awkwardly or directly on the ankle. Laceration of the tendon. Weakness of the gastrocnemius or soleus muscles in people with existing Achilles tendonitis places increased stress on the tendon. Steroid use has been linked to tendon weakness. Certain systemic diseases have been associated with tendon weakness. A sudden deceleration or stopping motions that cause an acute traumatic injury of the ankle. Injection of steroids to the involved tendon or the excessive use of steroids has been known to weaken tendons and make them susceptible to rupture. Contraction of the calf muscles while the foot is dorsiflexed (pointed toward the head) and the lower leg is moving forward. Symptoms A classic sign of an Achilles tendon rupture is the feeling of being hit in the Achilles are. There is often a "pop" sound. There may be little pain, but the person can not lift up onto his toes while weight bearing. Diagnosis In diagnosing an Achilles tendon rupture, the foot and ankle surgeon will ask questions about how and when the injury occurred and whether the patient has previously injured the tendon or experienced similar symptoms. The surgeon will examine the foot and ankle, feeling for a defect in the tendon that suggests a tear. Range of motion and muscle strength will be evaluated and compared to the uninjured foot and ankle. If the Achilles tendon is ruptured, the patient will have less strength in pushing down (as on a gas pedal) and will have difficulty rising on the toes. The diagnosis of an Achilles tendon rupture is typically straightforward and can be made through this type of examination. In some cases, however, the surgeon may order an MRI or other advanced imaging tests. Non Surgical Treatment Once the Achilles tendon is partially damaged, one should exercise great care. The risk of rupture is high and if pain is associated with walking, one should consult with an orthopedic surgeon or a sports physician. A complete rupture of the Achilles tendon is never treated at home. It is important to understand that there are no minerals, nutrients, or herbs to treat Achilles tendon injury and any delay just worsens the recovery. Surgical Treatment This injury is often treated surgically. Surgical care adds the risks of surgery, there are for you to view. After the surgery, the cast and aftercare is typically as follows. A below-knee cast (from just below the knee to the tips of the toes) is applied. The initial cast may be applied with your foot positioned in a downward direction to allow the ends of the tendon to lie closer together for initial healing. You may be brought back in 2-3 week intervals until the foot can be positioned at 90 degrees to the leg in the cast. The first 6 weeks in the cast are typically non-weight bearing with crutches or other suitable device to assist with the non-weight bearing requirement. After 6 weeks in the non-removable cast, a removable walking cast is started. The removable walking cast can be removed for therapy, sleeping and bathing. The period in the removable walking cast may need to last for an additional 2-6 weeks. Your doctor will review a home physical therapy program with you (more on this program later) that will typically start not long after your non-removable cast is removed. Your doctor may also refer you for formal physical therapy appointments. Typically, weight bearing exercise activities are kept restricted for at least 4 months or more. Swimming or stationary cycling activities may be allowed sooner. Complete healing may take 12 months or more. Prevention To reduce your chance of developing Achilles tendon problems, follow the following tips. Stretch and strengthen calf muscles. Stretch your calf to the point at which you feel a noticeable pull but not pain. Don't bounce during a stretch. Calf-strengthening exercises can also help the muscle and tendon absorb more force and prevent injury. Vary your exercises. Alternate high-impact sports, such as running, with low-impact sports, such as walking, biking or swimming. Avoid activities that place excessive stress on your Achilles tendons, such as hill running and jumping activities. Choose running surfaces carefully. Avoid or limit running on hard or slippery surfaces. Dress properly for cold-weather training and wear well-fitting athletic shoes with proper cushioning in the heels. Increase training intensity slowly. Achilles tendon injuries commonly occur after abruptly increasing training intensity. Increase the distance, duration and frequency of your training by no more than 10 percent each week.
