Overview
The Achilles tendon, or calcaneal tendon, is a large ropelike band of fibrous tissue in the back of the ankle that connects the powerful calf muscles to the heel bone (calcaneus). Sometimes called the heel cord, it is the largest tendon in the human body. When the calf muscles contract, the Achilles tendon is tightened, pulling the heel. This allows you to point your foot and stand on tiptoe. It is vital to such activities as walking, running, and jumping. A complete tear through the tendon, which usually occurs about 2 inches above the heel bone, is called an Achilles tendon rupture.
Causes
Ruptured Achilles tendons may result from falling from a height or down a hole. Increasing training intensity abruptly, boosting distance, frequency or duration by more than 10% a week. Failing to stretch before and after exercise. Repetitive training, especially uphill running. Deyhydration, which causes cramping and tightness in the calves. Taking antibiotics. Improper footwear. Explosive movements in competitive sports like basketball, soccer or track & field.
Symptoms
Patients with an Achilles tendon rupture will often complain of a sudden snap in the back of the leg. The pain is often intense. With a complete rupture, the individual will only be ambulate with a limp. Most people will not be able to climb stairs, run, or stand on their toes. Swelling around the calf may occur. Patients may often have had a sudden increase in exercise or intensity of activity. Some patients may have had recent corticosteroid injections or use of fluoroquinolone antibiotics. Some athletes may have had a prior injury to the tendon.
Diagnosis
Your doctor will ask you about your symptoms and examine you. He or she may also ask you about your medical history. Your doctor may ask you to do a series of movements or exercises to see how well you can move your lower leg. He or she may also examine your leg, heel and ankle and may squeeze your calf muscle to check the movement of your foot. You may need to have further tests to confirm if your tendon is torn, which may include the following. An ultrasound scan. This uses sound waves to produce an image of the inside of your leg. An MRI scan. This uses magnets and radio waves to produce images of the inside of your leg.
Non Surgical Treatment
This condition should be diagnosed and treated as soon as possible, because prompt treatment probably improves recovery. You may need to be referred urgently to see a doctor in an orthopaedic department or accident and emergency department. Meanwhile, if a ruptured Achilles tendon is suspected, you should not put any weight on that foot, so do not walk on it at all.Treatment options for an Achilles tendon rupture include surgical and non-surgical approaches. The decision of whether to proceed with surgery or non-surgical treatment is based on the severity of the rupture and the patient?s health status and activity level. Non-surgical treatment, which is generally associated with a higher rate of re-rupture, is selected for minor ruptures, less active patients, and those with medical conditions that prevent them from undergoing surgery. Non-surgical treatment involves use of a cast, walking boot, or brace to restrict motion and allow the torn tendon to heal.
Surgical Treatment
The patient is positioned prone after administration of either general or regional anesthesia. A longitudinal incision is made on either the medial or lateral aspect of the tendon. If a lateral incision is chosen care must be taken to identify and protect the sural nerve. Length of the incision averages 3 to 10 cm. Once the paratenon is incised longitudinally, the tendon ends are easily identifies. These are then re-approximated with either a Bunnell or Kessler or Krackow type suture technique with nonabsorbable suture. Next, the epitenon is repaired with a cross stitch technique. The paratenon should be repaired if it will be useful to prevent adhesions. Finally, a meticulous skin closure will limit wound complications. An alternative method is to perform a percutaneous technique, with a small incision (ranging from 2-4 cm). A few salient points include: the incision should be extended as needed, no self-retaining retractors should be used, and meticulous paratenon and wound closure is essential. Postoperatively the patient is immobilized in an equinous splint (usually 10?-15?) for 2 weeks. Immobilization may be extended if there is any concern about wound healing. At the 2-week follow-up, full weight bearing is permitted using a solid removable boot. At 6 weeks, aggressive physical therapy is prescribed and the patient uses the boot only for outdoor activity. At 12 weeks postoperatively, no further orthosis is recommended.
Prevention
Here are some suggestions to help to prevent this injury. Corticosteroid medication such as prednisolone, should be used carefully and the dose should be reduced if possible. But note that there are many conditions where corticosteroid medication is important or lifesaving. Quinolone antibiotics should be used carefully in people aged over 60 or who are taking steroids.
