An Achilles tendon rupture is a tear in the strong fibrous cord that connects the muscles in the back of your calf to your heel bone. The tendon can rupture partially or completely. Your Achilles tendon is the largest tendon in the body and plays a critical role. In fact, you rely on it every time you move your foot. The tendon helps you point your foot down, rise on your toes and push off as you walk. An Achilles tendon rupture is a serious injury. If you suspect you have torn your Achilles - especially if you hear a pop or snap in your heel and cannot walk properly - seek medical attention immediately.
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 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.
Ankle pain and swelling or feeling like the ankle has ?given out? after falling or stumbling. A loud audible pop when the ankle is injured. Patients may have a history of prior ankle pain or Achilles tendonitis, and may be active in sports. Swelling, tenderness and possible discoloration or ecchymosis in the Achilles tendon region. Indentation above the injured tendon where the torn tendon may be present. Difficulty moving around or walking. Individual has difficulty or is unable to move their ankle with full range of motion. MRI can confirm disruption or tear in the tendon. Inability to lift the toes.
The diagnosis of an Achilles tendon rupture can be made easily by an orthopedic surgeon. The defect in the tendon is easy to see and to palpate. No x-ray, MRI or other tests are necessary.
Non Surgical Treatment
Your doctor will advise you exactly when to start your home physical therapy program, what exercises to do, how much, and for how long to continue them. Alphabet Range of Motion exercises. Typically, the first exercise to be started (once out of a non-removable cast). While holding your knee and leg still (or cross your leg), you simply write the letters of the alphabet in an imaginary fashion while moving your foot and ankle (pretend that the tip of your toe is the tip of a pencil). Motion the capital letter A, then B, then C, all the way through Z. Do this exercise three times per day (or as your doctor advises). Freeze a paper cup with water, and then use the ice to massage the tendon area as deeply as tolerated. The massage helps to reduce the residual inflammation and helps to reduce the scarring and bulkiness of the tendon at the injury site. Do the ice massage for 15-20 minutes, three times per day (or as your doctor advises). Calf Strength exercises. This exercise is typically delayed and not used in the initial stages of rehabilitation, begin only when your doctor advises. This exercise is typically done while standing on just the foot of the injured side. Sometimes, the doctor will advise you to start with standing on both feet. Stand on a step with your forefoot on the step and your heel off the step. The heel and forefoot should be level (neither on your tip toes nor with your heel down). Lower your heel very slowly as low as it will go, then rise back up to the level starting position, again very slowly. This is not a fast exercise. Repeat the exercise as tolerated. The number of repetitions may be very limited at first. Progress the number of repetitions as tolerated. Do this exercise one to two times per day (or as your doctor advises).
Operative treatment involves a 6cm incision along the inner side of the tendon. The torn ends are then strongly stitched together with the correct tension. After the operation a below knee half cast is applied for 2 weeks. At 2 weeks a brace will be applied that will allow you to move the foot and fully weight-bear for a further 6 weeks. After this you will need physiotherapy. Surgery carries the general risks of any operation but the risk of re-rupture is greatly reduced to 2%. The best form of treatment is controversial with good results being obtained by both methods but surgery is generally recommended for patients under 60 years of age who are fit and active with an intra-substance tear.
