Overview Many of the muscles that move the foot are found in the lower leg. These muscles attach via tendons to various bones in the foot. The main muscles that move the foot downwards (plantar flex the foot) and propel the body forward are the calf muscles (gastrocnemius and soleus muscles). These muscles are connected to the heel bone (calcaneus) by the "rope like" Achilles tendon. Achilles tendon rupture is the term used to describe a complete tear of the Achilles tendon. The most common site for Achilles tendon rupture to occur is an area 2 - 6 cm. (1 - 2.5 in.) above where the tendon attaches to the calcaneus. Causes Factors that may increase your risk of Achilles tendon rupture include Age. The peak age for Achilles tendon rupture is 30 to 40. Your sex. Achilles tendon rupture is up to five times more likely to occur in men than in women. Playing recreational sports. Achilles tendon injuries occur more often in sports that involve running, jumping and sudden starts and stops - such as soccer, basketball and tennis. Steroid injections. Doctors sometimes inject steroids into an ankle joint to reduce pain and inflammation. However, this medication can weaken nearby tendons and has been associated with Achilles tendon ruptures. Certain antibiotics. Fluoroquinolone antibiotics, such as ciprofloxacin (Cipro) or levofloxacin (Levaquin), increase the risk of Achilles tendon rupture. Symptoms The most common symptom of Achilles tendonitis is a sudden surge of pain in the heel and back of the ankle at the point of injury which is often described as a snapping sensation in the heel. After the injury has occurred, patients then struggle or find it near impossible to bear any weight on the affected leg. Pain can often be most prominent first thing in the morning after the injury has been rested. Swelling and tenderness is also likely to appear in the area. Diagnosis During the physical exam, your doctor will inspect your lower leg for tenderness and swelling. In many cases, doctors can feel a gap in your tendon if a complete rupture has occurred. The doctor may also ask you to kneel on a chair or lie on your stomach with your feet hanging over the end of the exam table. He or she may then squeeze your calf muscle to see if your foot will automatically flex. If it doesn't, you probably have ruptured your Achilles tendon. If there's a question about the extent of your Achilles tendon injury, whether it's completely or only partially ruptured, your doctor may order a magnetic resonance imaging (MRI) scan. This painless procedure uses radio waves and a strong magnetic field to create a computerized image of the tissues of your body. Non Surgical Treatment Non-surgical management traditionally was selected for minor ruptures, less active patients, and those with medical conditions that prevent them from undergoing surgery. It traditionally consisted of restriction in a plaster cast for six to eight weeks with the foot pointed downwards (to oppose the ends of the ruptured tendon). But recent studies have produced superior results with much more rapid rehabilitation in fixed or hinged boots. Surgical Treatment Surgery could allow for a quicker healing time. The procedure generally involves making an incision in the back of your lower leg and stitching the torn tendon together. Depending on the condition of the tissue, the repair may be reinforced with other tendons. As with any surgery, the main complication is the risk for infection, however, this risk is reduced by using smaller incisions. Prevention The best treatment of Achilles tendonitis is prevention. Stretching the Achilles tendon before exercise, even at the start of the day, will help to maintain ankle flexibility. Problems with foot mechanics can also lead to Achilles tendonitis. This can often be treated with devices inserted into the shoes such as heel cups, arch supports, and custom orthotics.
