Overview
The Achilles' tendon is located in the leg just behind and above the heel. As the connection between the heel and calf muscle, its function is to allow the bending of the foot downwards. Generally if there is a tear to the Achilles' tendon it will be known as a rupture. This can be a partial tear or a complete tear, although partial tears are much rarer.
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
Many people say that a ruptured Achilles feels like being shot in the heel, if you can imagine how enjoyable that feels. You may hear a snap sound or feel a sudden sharp pain when the tendon tears. After a few moments, the pain settles and the back of the lower leg aches. You can walk and bear weight, but you may find it difficult to point the foot downward or push off the ground on the affected side. You will be unable to stand on tiptoe. Bruising and swelling are likely, and persistent pain will be present. Similar symptoms may be caused by an inflamed Achilles tendon (Achilles tendonitis), a torn calf muscle, arthritis of the ankle, or deep vein thrombosis in the calf, so an MRI or ultrasound scan will likely be used to diagnose your condition.
Diagnosis
Diagnosis of Achilles tendon rupture is not difficult. Usually, the diagnosis is obvious after examination of the ankle and performing some easy foot maneuvers (such as attempting to stand on the toes). When an Achilles tendon rupture occurs, there is often clinical confirmation of tenderness and bruising around the heel. A gap is felt when the finger is passed over the heel area, where the rupture has developed. All individuals with a full-blown rupture of the tendon are unable to stand on their toes. There is no blood work required in making a diagnosis of Achilles tendon rupture. The following are three common radiological tests to make a diagnosis of Achilles tendon rupture. Plain X-rays of the foot may reveal swelling of the soft tissues around the ankle, other bone injury, or tendon calcification. Ultrasound is the next most commonly ordered test to document the injury and size of the tear. For a partial tear of the Achilles tendon, the diagnosis is not always obvious on a physical exam and hence an ultrasound is ordered. This painless procedure can make a diagnosis of partial/full Achilles tendon rupture rapidly. Ultrasound is a relatively inexpensive, fast, and reliable test. MRI is often ordered when diagnosis of tendon rupture is not obvious on ultrasound or a complex injury is suspected. MRI is an excellent imaging test to assess for presence of any soft-tissue trauma or fluid collection. More importantly, MRI can help detect presence of tendon thickening, bursitis, and partial tendon rupture. However, MRI is expensive and is not useful if there is any bone damage.
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
Debate remains regarding the best form of treatment for a ruptured Achilles tendon. The 2 options are:immobilisation or operation. A recent meta-analysis of scientific studies showed that compared to immobilisation, an operation reduces the risk of re-rupture and allows a quicker return to work. An operation is not without risk and these must be balanced against the benefit of a lower re-rupture rate. Both treatments involve immobilisation for 8 weeks.
Prevention
The following can significantly reduce the risk of Achilles tendon rupture. Adequate stretching and warming up prior to exercising. If playing a seasonal sport, undertake preparatory exercises to build strength and endurance before the sporting season commences. Maintain a healthy body weight. This will reduce the load on the tendon and muscles. Use footwear appropriate for the sport or exercise being undertaken. Exercise within fitness limits and follow a sensible exercise programme. Increase exercise gradually and avoid unfamiliar strenuous exercise. Gradual warm down after exercising.
