Rupture of Achilles tendon is the most common among those taking place in the lower extremities, being twice as common in men than in women between 30-50 years old and usually caused while doing sport. There are some risk factors such as age or chronic treatments based on corticosteroids or antibiotics when belonging to Quinolones group. Spontaneous bilateral rupture of the Achilles tendon is much more infrequent, being almost exceptional in young and healthy patients without known pathological conditions.
There are a number of factors that can increase the risk of an Achilles tendon rupture, which include the following. You?re most likely to rupture your Achilles tendon during sports that involve bursts of jumping, pivoting and running, such as football or tennis. Your Achilles tendon becomes less flexible and less able to absorb repeated stresses, for example of running, as you get older. Small tears can develop in the fibres of the tendon and it may eventually completely tear. There is a very small risk of an Achilles tendon rupture if you have Achilles tendinopathy (also called Achilles tendinitis). This is where your tendon breaks down, which causes pain and stiffness in your Achilles tendon, both when you exercise and afterwards. If you take quinolone antibiotics and corticosteroid medicines, it can increase your risk of an Achilles tendon injury, particularly if you take them together. The exact reasons for this aren't fully understood at present.
Whereas calf strains and tendonitis may cause tightness or pain in the leg, Achilles tendon ruptures are typically accompanied by a popping sensation and noise at the time of the injury. In fact, some patients joke that the popping sound was loud enough to make them think they?d been shot. Seeing a board-certified orthopedic surgeon is the best way to determine whether you have suffered an Achilles tendon tear.
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
Achilles tendon ruptures can be treated non-operatively or operatively. Both of these treatment approaches have advantages and disadvantages. In general, younger patients with no medical problems may tend to do better with operative treatment, whereas patients with significant medical problems or older age may be best served with non-operative treatment. However, the decision of how the Achilles tendon rupture is treated should be based on each individual patient after the advantages and disadvantages of both treatment options are reviewed. It is important to realize that while Achilles tendon ruptures can be treated either non-operatively or operatively, they must be treated. A neglected Achilles tendon rupture (i.e. one where the tendon ends are not kept opposed) will lead to marked problems of the leg in walking, which may eventually lead to other limb and joint problems. Furthermore, late reconstruction of non-treated Achilles tendon rupture is significantly more complex than timely 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.
