Rupture of the Achilles tendon is a common injury in healthy, young, active individuals. The rupture is typically spontaneous and most commonly observed in individuals in between 24-45 years of age. The majority have had no prior history of pain or previous injury to the heel. In the majority of cases, rupture of the Achilles tendon occurs just a few centimeters above the heel bone. Common causes of Achilles tendinitis or rupture include advanced age, poor conditioning, and overexertion during exercise. In most cases, the individual rapidly performs activity like running or standing on the toes, which generates intense force on the tendon, leading to rupture. Achilles tendon rupture is often described as an abrupt break with instantaneous pain that is felt in the foot or heel area. The pain may radiate along the back of the leg and is often intense. Generally, walking may be difficult and the foot may drag. Most individuals claim that they felt like they were kicked in that area or even shot at. These symptoms lead to a suspicion of rupture of the Achilles tendon. Sometimes the tendon does not fully rupture but only a partial tear develops. The partial tear can also present with pain, and if not recognized, can rapidly develop into a full-blown rupture. In the majority of cases, the Achilles tendon rupture occurs just above the heel, but it may occur anywhere along the length of the tendon.
The Achilles tendon is most commonly injured by sudden plantarflexion or dorsiflexion of the ankle, or by forced dorsiflexion of the ankle outside its normal range of motion. Other mechanisms by which the Achilles can be torn involve sudden direct trauma to the tendon, or sudden activation of the Achilles after atrophy from prolonged periods of inactivity. Some other common tears can occur from overuse while participating in intense sports. Twisting or jerking motions can also contribute to injury. Fluoroquinolone antibiotics, famously ciprofloxacin, are known to increase the risk of tendon rupture, particularly achilles.
A sudden and severe pain may be felt at the back of the ankle or calf, often described as "being hit by a rock or shot" or "like someone stepped onto the back of my ankle." The sound of a loud pop or snap may be reported. A gap or depression may be felt and seen in the tendon about 2 inches above the heel bone. Initial pain, swelling, and stiffness may be followed by bruising and weakness. The pain may decrease quickly, and smaller tendons may retain the ability to point the toes. Without the Achilles tendon, though, this would be very difficult. Standing on tiptoe and pushing off when walking will be impossible. A complete tear is more common than a partial tear.
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.
Surgery is the most common treatment for this condition. An incision is made in the lower leg and the tendon is sewn back together. A cast, splint, walking boot, or brace is worn for 6-8 weeks. One of the benefits of surgery is that it lowers the risk of re-rupturing the tendon. Surgery may also be a better option if you are athletic.
