The Achilles tendon is the tough sinew that attaches the calf muscle to the back of the calcaneus, or heel bone. It is also known as the tendo calcaneus or the tendo Achilles and happens to be one of the longest tendons in the body. An Achilles tendon rupture occurs when the Achilles tendon is partially or completely broken or torn. The average age of patients who suffer Achilles tendon ruptures is 30 to 40 years. The male-to-female ratio is nearly 20 to 1.
As with any muscle or tendon in the body, the Achilles tendon can be torn if there is a high force or stress on it. This can happen with activities which involve a forceful push off with the foot, for example, in football, running, basketball, diving, and tennis. The push off movement uses a strong contraction of the calf muscles which can stress the Achilles tendon too much. The Achilles tendon can also be damaged by injuries such as falls, if the foot is suddenly forced into an upward-pointing position, this movement stretches the tendon. Another possible injury is a deep cut at the back of the ankle, which might go into the tendon. Sometimes the Achilles tendon is weak, making it more prone to rupture. Factors that weaken the Achilles tendon are as follows. Corticosteroid medication (such as prednisolone) - mainly if it is used as long-term treatment rather than a short course. Corticosteroid injection near the Achilles tendon. Certain rare medical conditions, such as Cushing's syndrome, where the body makes too much of its own corticosteroid hormones. Increasing age. Tendonitis (inflammation) of the Achilles tendon. Other medical conditions which can make the tendon more prone to rupture; for example, rheumatoid arthritis, gout and systemic lupus erythematosus (SLE), lupus. Certain antibiotic medicines may slightly increase the risk of having an Achilles tendon rupture. These are the quinolone antibiotics such as ciprofloxacin and ofloxacin. The risk of having an Achilles tendon rupture with these antibiotics is actually very low, and mainly applies if you are also taking corticosteroid medication or are over the age of about 60.
Tendon strain or tendon inflammation (tendonitis) can occur from tendon injury or overuse and can lead to a rupture. Call your doctor if you have signs of minor tendon problems. Minor tenderness and possible swelling increases with activity. There is usually no specific event causing sudden pain and no obvious gap in the tendon. You can still walk or stand on your toes. Acute calf pain and swelling can indicate a tear or partial tear of the Achilles tendon where it meets the calf muscle. You may still be able to use that foot to walk, but you will need to see a specialist such as an orthopedic surgeon. Surgery is not usually done for partial tears. Sometimes special heel pads or orthotics in your shoes may help. Follow up with your doctor to check for tendonitis or strain before resuming activity, because both can increase the risk of tendon rupture. Any acute injury causing pain, swelling, and difficulty with weight-bearing activities such as standing and walking may indicate you have a tear in your Achilles tendon. Seek prompt medical attention from your doctor or emergency department. Do not delay! Early treatment results in better outcome. If you have any question or uncertainty, get it checked.
Laboratory studies usually are not necessary in evaluating and diagnosing an Achilles tendon rupture or injury, although evaluation may help to rule out some of the other possibilities in the differential diagnosis. Plain radiography. Radiographs are more useful for ruling out other injuries than for ruling in Achilles tendon ruptures. Ultrasonography of the leg and thigh can help to evaluate the possibility of deep venous thrombosis and also can be used to rule out a Baker cyst, in experienced hands, ultrasonography can identify a ruptured Achilles tendon or the signs of tendinosis. Magnetic resonance imaging (MRI). MRI can facilitate definitive diagnosis of a disrupted tendon and can be used to distinguish between paratenonitis, tendinosis, and bursitis.
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.
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.
To help prevent an Achilles tendon injury, it is a good practice to perform stretching and warm-up exercises before any participating in any activities. Gradually increase the intensity and length of time of activity. Muscle conditioning may help to strengthen the muscles in the body.
