Overview
The Achilles tendon is the largest and strongest tendon in the human body. The Achilles tendon connects the heel bone (calcaneus) to the muscles at the back of the calf (using gastrocnemius and soleus muscles). The synchronous function of the tendon and calf muscles is critical for activities like jumping, running, standing on the toe, and climbing stairs. When climbing stairs or running, the forces within the tendon have been measured and indicate that the structure is able to withstand at least 10 times the body weight of the individual. The function of the Achilles tendon is to help raise your heel as you walk. The tendon also assists in pushing up the toes and lifting the rear of the heel. Without an intact Achilles tendon, almost any motion with the ankle (for example, walking or running) is difficult.
Causes
Causes of and contributors to Achilles tendon rupture include trauma (caused by injury, usually an acceleration injury such as pushing off or jumping up). Preceding tendon problems. Chronic Achilles tendonitis (can lead to small tears within the tendon, increasingly weakening it). Certain drug therapies/treatments. Drugs that have been linked to Achilles tendon rupture include. Fluoroquinolone antibiotics - after nearly 900 reports of tendon ruptures, tendonitis and other tendon disorders (most associated with the Achilles tendon) linked to Ciprofloxacin (Cipro) alone were collected in the U.S. Food and Drug Administration (FDA)?s database, at least one public-interest group petitioned the FDA to recommend that a "Black Box Warning" be added to Cipro's packaging. Some researchers speculate this class of antibiotics is toxic to tendon fibers, and that in some cases may reduce their blood supply. Patients should at least be more aware of the potential for ruptures so that they can be switched to other antibiotics at the onset of early warning signals such as tendon pain.
Symptoms
The pain from an Achilles tendon rupture is usually felt in the back of the lower leg, in the area 2 to 6 cm. above the Achilles tendon's attachment to the calcaneus. Individuals with an Achilles tendon rupture often describe a "pop" or similar feeling at the time of the injury. A "hole" or defect in the Achilles tendon can usually be felt under the skin in this area. A limp and inability to rise up on the toes of the affected foot are usually present. If the affected foot does not plantar flex when the calf muscles are squeezed an Achilles tendon rupture is very likely.
Diagnosis
In order to diagnose Achilles tendon rupture a doctor or physiotherapist will give a full examination of the area and sometimes an X ray is performed in order to confirm the diagnosis. A doctor may also recommend an MRI or CT scan is used to rule out any further injury or complications.
Non Surgical Treatment
Treatment of the initial injury is with use of ice, elevation, and immobilization. If suspected you should contact your podiatrist or physician. Further treatment with continued immobilization, pain medication, or anti-inflammatory medications may be advised. If casted the foot is usually placed in a plantarflexed position to decrease the stretch on the tendon. As healing progresses the cast is changed to a more dorsiflexed position at the ankle. The casting processes can be up to 8 weeks or more.
Surgical Treatment
Some surgeons feel an early surgical repair of the tendon is beneficial. The surgical option was long thought to offer a significantly smaller risk of re-rupture compared to traditional non-operative management (5% vs 15%). Of course, surgery imposes higher relative risks of perioperative mortality and morbidity e.g. infection including MRSA, bleeding, deep vein thrombosis, lingering anesthesia effects, etc.
Prevention
The following can significantly reduce the risk of Achilles tendon rupture. Adequate stretching and warming up prior to exercising. If playing a seasonal sport, undertake preparatory exercises to build strength and endurance before the sporting season commences. Maintain a healthy body weight. This will reduce the load on the tendon and muscles. Use footwear appropriate for the sport or exercise being undertaken. Exercise within fitness limits and follow a sensible exercise programme. Increase exercise gradually and avoid unfamiliar strenuous exercise. Gradual ?warm down? after exercising.
