Ruptured Achilles Tendon Fiction
The Achilles tendon is an important part of the leg. It is located just behind and above the heel. It joins the heel bone to the calf muscles. Its function is to help in bending the foot downwards at the ankle (this movement is called plantar flexion by doctors). If the Achilles tendon is torn, this is called an Achilles tendon rupture. The tear may be either partial or complete. In a partial tear, the tendon is partly torn but still joined to the calf muscle. With complete tears, the tendon is completely torn so that the connection between the calf muscles and the ankle bone is lost.
People who commonly fall victim to Achilles rupture or tear include recreational athletes, people of old age, individuals with previous Achilles tendon tears or ruptures, previous tendon injections or quinolone use, extreme changes in training intensity or activity level, and participation in a new activity. Most cases of Achilles tendon rupture are traumatic sports injuries. The average age of patients is 29-40 years with a male-to-female ratio of nearly 20:1. Fluoroquinolone antibiotics, such as ciprofloxacin, and glucocorticoids have been linked with an increased risk of Achilles tendon rupture. Direct steroid injections into the tendon have also been linked to rupture. Quinolone has been associated with Achilles tendinitis and Achilles tendon ruptures for some time. Quinolones are antibacterial agents that act at the level of DNA by inhibiting DNA Gyrase. DNA Gyrase is an enzyme used to unwind double stranded DNA which is essential to DNA Replication. Quinolone is specialized in the fact that it can attack bacterial DNA and prevent them from replicating by this process, and are frequently prescribed to the elderly. Approximately 2% to 6% of all elderly people over the age of 60 who have had Achilles ruptures can be attributed to the use of quinolones.
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.
The doctor may look at your walking and observe whether you can stand on tiptoe. She/he may test the tendon using a method called Thompson?s test (also known as the calf squeeze test). In this test, you will be asked to lie face down on the examination bench and to bend your knee. The doctor will gently squeeze the calf muscles at the back of your leg, and observe how the ankle moves. If the Achilles tendon is OK, the calf squeeze will make the foot point briefly away from the leg (a movement called plantar flexion). This is quite an accurate test for Achilles tendon rupture. If the diagnosis is uncertain, an ultrasound or MRI scan may help. An Achilles tendon rupture is sometimes difficult to diagnose and can be missed on first assessment. It is important for both doctors and patients to be aware of this and to look carefully for an Achilles tendon rupture if it is suspected.
Non Surgical Treatment
Non-operative treatment consists of placing the foot in a downward position [equinus] and providing relative immobilization of the foot in this position until the Achilles has healed. This typically involves some type of stable bracing or relative immobilization for 6 weeks, often with limited or no weight bearing. The patient can then be transitioned to a boot with a heel lift and then gradually increase their activity level within the boot. It is very important that the status of the Achilles is monitored throughout non-operative treatment. This can be done by examination or via ultrasound. If there is evidence of gapping or non-healing, surgery may need to be considered. Formal protocols have been developed to help optimize non-operative treatments and excellent results have been reported with these protocols. The focus of these treatments is to ensure that the Achilles rupture is in continuity and is healing in a satisfactory manner. The primary advantage of non-operative treatment is that without an incision in this area, there are no problems with wound healing or infection. Wound infection following Achilles tendon surgery can be a devastating complication and therefore, for many patients, non-operative treatment should be contemplated. The main disadvantage of non-operative treatment is that the recovery is probably slower. On average, the main checkpoints of recovery occur 3-4 weeks quicker with operative treatment than with non-operative treatment. In addition, the re-rupture rate appears to be higher with some non-operative treatments. Re-rupture typically occurs 8-18 months after the original injury.
There are a variety of ways to repair an Achilles tendon rupture. The most common method is an open repair. This starts with an incision made on the back of the lower leg starting just above the heel bone. After the surgeon finds the two ends of the ruptured tendon, these ends are sewn together with sutures. The incision is then closed. Another repair method makes a small incision on the back of the lower leg at the site of the rupture. A series of needles with sutures attached is passed through the skin and Achilles tendon and then brought out through the small incision. The sutures are then tied together. The best surgical technique for your Achilles rupture will be determined by your orthopaedic foot and ankle surgeon.
There are things you can do to help prevent an Achilles tendon injury. You should try the following. Cut down on uphill running. Wear shoes with good support that fit well. Always increase the intensity of your physical activity slowly. Stop exercising if you feel pain or tightness in the back of your calf or heel.
