Overview

An Achilles tendon injury can affect both professional and amateur athletes. The Achilles tendon is one of the longer tendons in your body, stretching from the bones of your heel to your calf muscles. You can feel it, a springy band of tissue at the back of your ankle and above your heel. It allows you to extend your foot and point your toes to the floor. Unfortunately, it's a commonly injured tendon. Many Achilles tendon injuries are caused by tendinitis, in which the tendon becomes swollen and painful. In a severe Achilles tendon injury, too much force on the tendon can cause it to tear partially or rupture completely.

Causes
Repeated stress from a variety of causes is often the cause of Achilles tendon injury. The stress may occur from any of the following. Excessive activity or overuse. Flat feet. Poorly fitting or inadequate shoes. Inadequate warm-up or proper conditioning. Jogging or running on hard surfaces. Older recreational athlete. Previous Achilles tendon injury (tendonitis/rupture). Repeated steroid injections. Sudden changes in intensity of exercise. Use of fluoroquinolone antibiotics (especially in children). Trauma to the ankle. Tense calf muscles prior to exercise. Weak calf muscles.

Symptoms
A person with a ruptured Achilles tendon may experience one or more of the following. Sudden pain (which feels like a kick or a stab) in the back of the ankle or calf, often subsiding into a dull ache. A popping or snapping sensation. Swelling on the back of the leg between the heel and the calf. Difficulty walking (especially upstairs or uphill) and difficulty rising up on the toes. These symptoms require prompt medical attention to prevent further damage. Until the patient is able to see a doctor, the "R.I.C.E." method should be used. This involves, rest. Stay off the injured foot and ankle, since walking can cause pain or further damage. Ice. Apply a bag of ice covered with a thin towel to reduce swelling and pain. Do not put ice directly against the skin. Compression. Wrap the foot and ankle in an elastic bandage to prevent further swelling. Elevation. Keep the leg elevated to reduce the swelling. It should be even with or slightly above heart level.

Diagnosis
The diagnosis of an Achilles tendon rupture is made entirely on physical examination. Often, there is a substantial defect in the Achilles from 2-5 cm before it inserts into the heel bone. However, the main test is to determine whether the Achilles has been ruptured is the Thompson test. This essentially involves placing the patient on their stomach and squeezing the calf muscle. If the Achilles is intact, the foot will rise [plantar flex]. If it is ruptured, the foot will not move and will tend to be in a lower lying position.

Non Surgical Treatment
Nonsurgical treatment involves extended casting, special braces, orthotics, and physical therapy. Avoids the normal complications and expenses of surgery. Some studies show the outcome is similar to surgery in regard to strength and function. There is risk of an over-lengthened tendon with inadequate tension. Extended immobilization can lead to more muscle weakness. Nonsurgical treatment has a higher incidence of re-rupture than surgical repair. Nonsurgical treatment is often used for nonathletes or for those with a general low level of physical activity who would not benefit from surgery. The elderly and those with complicating medical conditions should also consider conservative nonsurgical treatment.


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.
