The exact number of people who develop Achilles tendon injury is not known, because many people with mild tendonitis or partial tear do not seek medical help. It is believed to be more common in men but with the recent participation of women in athletics, the incidence of Achilles tendon injury is also increasing in this population. Overall, injury to the Achilles tendon is by far most common in the athlete/active individual.Causes
An Achilles tendon injury might be caused by several factors. Overuse. Stepping up your level of physical activity too quickly. Wearing high heels, which increases the stress on the tendon. Problems with the feet, an Achilles tendon injury can result from flat feet, also known as fallen arches or overpronation. In this condition, the impact of a step causes the arch of your foot to collapse, stretching the muscles and tendons. Muscles or tendons in the leg that are too tight. Achilles tendon injuries are common in people who participate in the following sports. Running. Gymnastics. Dance. Football. Baseball. Softball. Basketball. Tennis. Volleyball. You are more likely to tear an Achilles tendon when you start moving suddenly. For instance, a sprinter might get one at the start of a race. The abrupt tensing of the muscle can be too much for the tendon to handle. Men older than age 30 are particularly prone to Achilles tendon injuries.Symptoms
You may notice the symptoms come on suddenly during a sporting activity or injury. You might hear a snap or feel a sudden sharp pain when the tendon is torn. The sharp pain usually settles quickly, although there may be some aching at the back of the lower leg. After the injury, the usual symptoms are a flat-footed type of walk. You can walk and bear weight, but cannot push off the ground properly on the side where the tendon is ruptured. Inability to stand on tiptoe. If the tendon is completely torn, you may feel a gap just above the back of the heel. However, if there is bruising then the swelling may disguise the gap. If you suspect an Achilles tendon rupture, it is best to see a doctor urgently, because the tendon heals better if treated sooner rather than later. A person with a ruptured Achilles tendon may experience one or more of the following. Sudden pain (which feels like a kick or a stab) in the back of the ankle or calf, often subsiding into a dull ache. A popping or snapping sensation. Swelling on the back of the leg between the heel and the calf. Difficulty walking (especially upstairs or uphill) and difficulty rising up on the toes.Diagnosis
On physical examination the area will appear swollen and ecchymotic, which may inhibit the examiners ability to detect a palpable defect. The patient will be unable to perform a single heel raise. To detect the presence of a complete rupture the Thompson test can be performed. The test is done by placing the patient prone on the examination table with the knee flexed to 90?, which allows gravity and the resting tension of the triceps surae to increase the dorsiflexion at the ankle. The calf muscle is squeezed by the examiner and a lack of planar flexion is noted in positive cases. It is important to note that active plantar flexion may still be present in the face of a complete rupture due to the secondary flexor muscles of the foot. It has been reported that up to 25% of patients may initially be missed in the emergency department due to presence of active plantar flexion and swelling over the Achilles tendon, which makes palpation of a defect difficult.Non Surgical Treatment
Two treatment options are casting or surgery. If an Achilles tendon rupture What is distraction osteogenesis? untreated then it may not heal properly and could lead to loss of strength. Decisions about treatment options should be made on an individual basis. Non-surgical management traditionally is selected for minor ruptures, less active patients, and those with medical conditions that prevent them from undergoing surgery. The goal of casting is to allow the tendon to slowly heal over time. The foot and ankle are positioned to bring the torn ends of the tendon close together. Casting or bracing for up to 12 weeks or more may be necessary. This method can be effective and avoids some risks, such as infection, associated with surgery. However, the likelihood of re-rupture may be higher with a non-surgical approach and recovery can take longer.Surgical Treatment
Most published reports on surgical treatment fall into 3 different surgical approach categories that include the following: direct open, minimally invasive, and percutaneous. In multiple studies surgical treatment has demonstrated a lower rate of re-rupture compared to nonoperative treatment, but surgical treatment is associated with a higher rate of wound healing problems, infection, postoperative pain, adhesions, and nerve damage. Most commonly the direct open approach involves a 10- to 18-cm posteromedial incision. The minimally invasive approach has a 3- to 10-cm incision, and the percutaneous approach involves repairing the tendon through multiple small incisions. As with nonsurgical treatment there exists wide variation in the reported literature regarding postoperative treatment protocols. Multiple comparative studies have been published comparing different surgical approaches, repair methods, or postoperative treatment protocols.Prevention
You can help to reduce your risk of an injury to your Achilles tendon by doing the following. When you start a new exercise regime, gradually increase the intensity and the length of time you spend being active. Warm up your muscles before you exercise and cool them down after you have finished. The benefit of stretching before or after exercise is unproven. However, it may help to stretch your calf muscles, which will help to lengthen your Achilles tendon, before you exercise. Wear appropriate and well-fitting shoes when you exercise.
