An Achilles tendon rupture is also known as a rupture of the gastrocnemius tendon, or the common calcanean tendon. The tendon is actually composed of 5 different tendons, the two most important being the superficial digital flexor and gastrocnemius tendons. The gastrocnemius tendon is the largest of these, and is the most powerful extensor of the hock (ankle) joint. Both the superficial digital flexor and gastrocnemius tendons attach to the heel bone, called the calcaneus bone. A rupture of the Achilles tendon may be a partial tear, which means just the gastrocnemius is torn, or a complete tear, in which all five tendons have been torn. (show diagrams, normal anatomy vs partial vs complete tears).
Causes of and contributors to Achilles tendon rupture include trauma (caused by injury, usually an acceleration injury such as pushing off or jumping up). Preceding tendon problems. Chronic Achilles tendonitis (can lead to small tears within the tendon, increasingly weakening it). Certain drug therapies/treatments. Drugs that have been linked to Achilles tendon rupture include. Fluoroquinolone antibiotics - after nearly 900 reports of tendon ruptures, tendonitis and other tendon disorders (most associated with the Achilles tendon) linked to Ciprofloxacin (Cipro) alone were collected in the U.S. Food and Drug Administration (FDA)?s database, at least one public-interest group petitioned the FDA to recommend that a "Black Box Warning" be added to Cipro's packaging. Some researchers speculate this class of antibiotics is toxic to tendon fibers, and that in some cases may reduce their blood supply. Patients should at least be more aware of the potential for ruptures so that they can be switched to other antibiotics at the onset of early warning signals such as tendon pain.
Patients present with acute posterior ankle/heel pain and may give a history of ?felt like someone kicked me from behind?. Patients may report a direct injury, or report the pain started with jumping or landing on a dorsiflexed foot. It is important to elicit in the history any recent steroid or flouroqunolone usage including local steroid injections, and also any history of endocrine disorders or systemic inflammatory conditions.
When Achilles tendon injury is suspected, the entire lower lag is examined for swelling, bruising, and tenderness. If there is a full rupture, a gap in the tendon may be noted. Patients will not be able to stand on the toes if there is a complete Achilles tendon rupture. Several tests can be performed to look for Achilles tendon rupture. One of the most widely used tests is called the Thompson test. The patient is asked to lie down on the stomach and the examiner squeezes the calf area. In normal people, this leads to flexion of the foot. With Achilles tendon injury, this movement is not seen.
Non Surgical Treatment
Initial treatment for sprains and strains should occur as soon as possible. Remember RICE! Rest the injured part. Pain is the body's signal to not move an injury. Ice the injury. This will limit the swelling and help with the spasm. Compress the injured area. This again, limits the swelling. Be careful not to apply a wrap so tightly that it might act as a tourniquet and cut off the blood supply. Elevate the injured part. This lets gravity help reduce the swelling by allowing fluid and blood to drain downhill to the heart. Over-the-counter pain medication is an option. Acetaminophen (Tylenol) is helpful for pain, but ibuprofen (Motrin, Advil, Nuprin) might be better, because these medications relieve both pain and inflammation. Remember to follow the guidelines on the bottle for appropriate amounts of medicine, especially for children and teens.
Surgery may be indicated directly following injury rather than conservative care. Repair of an achilles tendon rupture is greatly varied for each clinical situation. There may be a direct repair of the ends of the tendon with suture, or possibly a tendon graft used to augment the tendon. Post-operatively, the period of immobilization will depend on the size of the defect that was repaired and how it was completed. Usually the immobilization is between 6-10 weeks. This repair may allow for a complete return to normal function, but in many instances the healing is complicated with adhesions and a partial loss of range of motion. There may be a continued soft tissue defect noted and a permanent or prolonged swelling.
Good flexibility of the calf muscles plays an essential role in the prevention of Achilles tendon injuries. It is also important to include balance and stability work as part of the training programme. This should include work for the deep-seated abdominal muscles and for the muscles that control the hip. This might at first appear odd, given the fact that the Achilles are a good distance from these areas, but developing strength and control in this area (core stability) can boost control at the knee and ankle joints. Training errors should be avoided. The volume, intensity and frequency of training should be monitored carefully, and gradually progressed, particularly when introducing new modes of training to the programme. Abrupt changes in training load are the primary cause of Achilles tendinopathy.
