Overview

A rupture of the Achilles tendon means that there has been either a complete, or partial, tear of the tendon which connects the calf muscles to the heel bone. Usually this occurs just above insertion on the heel bone, although it can happen anywhere along the course of the tendon. Achilles tendon rupture occurs in people that engage in strenuous activity, who How do you grow? 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).

Causes
An Achilles tendon rupture is often caused by overstretching the tendon. This typically occurs during intense physical activity, such as running or playing basketball. Pushing off from the foot while the knee is straight, pivoting, jumping, and running are all movements that can overstretch the Achilles tendon and cause it to rupture. A rupture can also occur as the result of trauma that causes an over-stretching of the tendon, such as suddenly tripping or falling from a significant height. The Achilles tendon is particularly susceptible to injury if it is already weak. Therefore, individuals who have a history of tendinitis or tendinosis are more prone to a tendon rupture. Similarly, individuals who have arthritis and overcompensate for their joint pain by putting more stress on the Achilles tendon may also be more susceptible to an Achilles tendon rupture.

Symptoms
Patients present with acute posterior ankle/heel pain and may give a history of ?felt like someone kicked me from behind?. Patients may report a direct injury, or report the pain started with jumping or landing on a dorsiflexed foot. It is important to elicit in the history any recent steroid or flouroqunolone usage including local steroid injections, and also any history of endocrine disorders or systemic inflammatory conditions.

Diagnosis
Other less serious causes of pain in the back of the lower leg include Achilles tendonitis or bursitis. To distinguish between these possibilities, your physician will take a thorough history and examine your lower leg to look for signs of a rupture. The presence of a defect in the tendon that can be felt, evidence of weakness with plantarflexion, and a history consistent with Achilles tendon rupture are usually sufficient for diagnosis. Your physician may also perform a ?Thompson test,? which consists of squeezing the calf muscles of the affected leg. With an intact Achilles tendon, the foot will bend downward; however, with a complete rupture of the tendon, the foot will not move. In cases where the diagnosis is equivocal, your physician may order an MRI of the leg to diagnose a rupture of the Achilles tendon.

Non Surgical Treatment
Treatment of a ruptured Achilles tendon is usually conservative (non-operative) in a Controlled Motion Ankle (CAM) Boot or it may require surgery. The current consensus based on research is to treat them conservatively since the functional outcome and chance of re-rupture is similar (7% to 15%) using both approaches but surgical intervention has a higher risk of infection. Achilles tendon surgery is usually considered if your Achilles has re-ruptured or there is delay of two weeks between the rupture and the diagnosis and commencement of conservative bracing and treatment.


Surgical Treatment
There are a variety of ways to repair an Achilles tendon rupture. The most common method is an open repair. This starts with an incision made on the back of the lower leg starting just above the heel bone. After the surgeon finds the two ends of the ruptured tendon, these ends are sewn together with sutures. The incision is then closed. Another repair method makes a small incision on the back of the lower leg at the site of the rupture. A series of needles with sutures attached is passed through the skin and Achilles tendon and then brought out through the small incision. The sutures are then tied together. The best surgical technique for your Achilles rupture will be determined by your orthopaedic foot and ankle surgeon.
