Overview

An Achilles tendon rupture is a complete or partial tear that occurs when the tendon is stretched beyond its capacity. Forceful jumping or pivoting, or sudden accelerations of running, can overstretch the tendon and cause a tear. An injury to the tendon can also result from falling or tripping. Achilles tendon ruptures are most often seen in ?weekend warriors? - typically, middle-aged people participating in sports in their spare time. Less commonly, illness or medications, such as steroids or certain antibiotics, may weaken the tendon and contribute to ruptures.

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
Symptoms of an Achilles tendon injury are as follows. Pain along the back of your foot and above your heel, especially when stretching your ankle or standing on your toes; with tendinitis, pain may be mild and worsen gradually. If you rupture the tendon, pain can be abrupt and severe. Tenderness. Swelling. Stiffness. Hearing a snapping or popping noise during the injury. Difficulty flexing your foot or pointing your toes (in complete tears of the tendon).

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 it has ruptured completely. 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 an ultrasound or MRI scan. These painless procedures create images of the tissues of your body.

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
Thanks to a new surgical technique, operative procedures are often more beneficial.The operative treatment of Achilles tendon ruptures has significantly changed in recent years. The objective today is to connect the torn tendons using modern suture and possibly adhesive materials. Through small surgical incisions the ends of the torn tendon are surgically exposed, and sutures are used to tie the ends permanently together. Thus, the operated repaired tendon is again resilient within a reasonable time. The cast treatment and walking on crutches required in the past, is with this procedure usually not necessary. Instead, functional treatment following the surgery involves wearing a special boot, meaning that the patient can put weight onto the operated leg again within a few days after surgery. Physical therapy training will start immediately following the operation. The philosophy behind such an early functional treatment is that tissue adequately adapts to stress and thus accelerates the healing process. For the patient, the modern surgical treatment of an Achilles tendon rupture has the distinct advantage that no prolonged hospital stay is necessary. Hospital stay usually lasts only a few days. Using crutches, patients can return to work soon after the surgery.

Prevention
To help reduce your chance of getting Achilles tendon rupture, take the following steps. Do warm-up exercises before an activity and cool down exercises after an activity. Wear proper footwear. Maintain a healthy weight. Rest if you feel pain during an activity. Change your routine. Switch between high-impact activities and low-impact activities. Strengthen your calf muscle with exercises.
