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
Achilles tendon rupture occurs in people that engage in strenuous activity, who are usually sedentary and have weakened tendons, or in people who have had previous chronic injury to their Achilles tendons. Previous injury to the tendon can be caused by overuse, improper stretching habits, worn-out or improperly fitting shoes, or poor biomechanics (flat-feet). The risk of tendon rupture is also increased with the use of quinolone antibiotics (e.g. ciprofloxacin, Levaquin).
Symptoms
Whereas calf strains and tendonitis may cause tightness or pain in the leg, Achilles tendon ruptures are typically accompanied by a popping sensation and noise at the time of the injury. In fact, some patients joke that the popping sound was loud enough to make them think theyd been shot. Seeing a board-certified orthopedic surgeon is the best way to determine whether you have suffered an Achilles tendon tear.
Diagnosis
The actual area of an Achilles tendon rupture cannot be seen on x-ray. Therefore, although x-rays are often done to rule out bony injuries in individuals with an Achilles tendon rupture these x-rays are usually normal. Diagnostic ultrasound of the tendon can be performed to assess the integrity of the tendon. Other diagnostic tests, such as MRI's, may also be required in difficult cases.
Non Surgical Treatment
Non-surgical treatment of Achilles tendon rupture is usually reserved for patients who are relatively sedentary or may be at higher risk for complications with surgical intervention (due to other associated medical problems). This involves a period of immobilization, followed by range of motion and strengthening exercises; unfortunately, it is associated with a higher risk of re-rupture of the tendon, and possibly a less optimal functional outcome.
Surgical Treatment
An Achilles tendon rupture is a complete tear of the fibrous tissue that connects the heel to the calf muscle. This is often caused by a sudden movement that overextends the tendon and usually occurs while running or playing sports such as basketball or racquetball. Achilles tendon rupture can affect anyone, but occurs most often in middle-aged men.
Prevention
Prevention centers on appropriate daily Achilles stretching and pre-activity warm-up. Maintain a continuous level of activity in your sport or work up gradually to full participation if you have been out of the sport for a period of time. Good overall muscle conditioning helps maintain a healthy tendon.
