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.
Your Achilles tendon helps you point your foot downward, rise on your toes and push off your foot as you walk. You rely on it virtually every time you move your foot. Rupture usually occurs in the section of the tendon located within 2.5 inches (6 centimeters) of the point where it attaches to the heel bone. This section may be predisposed to rupture because it gets less blood flow, which may impair its ability to heal. Ruptures often are caused by a sudden increase in the amount of stress on your Achilles tendon. Common examples include increasing the intensity of sports participation, falling from a height, stepping into a hole.
Patients with an Achilles tendon rupture will often complain of a sudden snap in the back of the leg. The pain is often intense. With a complete rupture, the individual will only be ambulate with a limp. Most people will not be able to climb stairs, run, or stand on their toes. Swelling around the calf may occur. Patients may often have had a sudden increase in exercise or intensity of activity. Some patients may have had recent corticosteroid injections or use of fluoroquinolone antibiotics. Some athletes may have had a prior injury to the tendon.
Some patients mistakenly believe the tendon is working if they can push the foot down, however, patients will usually be able to move the foot up and down while sitting because the other surrounding muscles and tendons are still intact. Trying to push up while standing and applying body weight to the foot will reveal the true weakness. Sensation and circulation to the foot and ankle will be normal. In addition, x-rays will be normal unless the Achilles injury involves pulling off (avulsion) of the bone on the calcaneus (heel bone). This is quite rare, occurring in only a small fraction of patients with Achilles injuries. Patients suffering this type of Achilles avulsion injury tend to be older with weaker bone. Imaging Studies. Plain x-rays will be negative in patients who have suffered an Achilles tendon rupture. The rupture can be seen on ultrasound or MRI. However, these studies are not indicated for acute ruptures unless there is some uncertainty about the diagnosis. For chronic problems of the Achilles or ruptures that are old, an MRI may be very helpful.
Non Surgical Treatment
A medical professional will take MRI scans to confirm the diagnosis and indicate the extent of the injury. Sometimes the leg is put in a cast and allowed to heal without surgery. This is generally not the preferred method, particularly for young active people. Surgery is the most common treatment for an achilles tendon rupture.
Surgery could allow for a quicker healing time. The procedure generally involves making an incision in the back of your lower leg and stitching the torn tendon together. Depending on the condition of the tissue, the repair may be reinforced with other tendons. As with any surgery, the main complication is the risk for infection, however, this risk is reduced by using smaller incisions.
You can help to reduce your risk of an injury to your Achilles tendon by doing the following. When you start a new exercise regime, gradually increase the intensity and the length of time you spend being active. Warm up your muscles before you exercise and cool them down after you have finished. The benefit of stretching before or after exercise is unproven. However, it may help to stretch your calf muscles, which will help to lengthen your Achilles tendon, before you exercise. Wear appropriate and well-fitting shoes when you exercise.
