The Achilles tendon is a delicate part of the body, and injuries to the Achilles tendon are especially prevalent for some athletes and sports enthusiasts. So how should we prevent and treat Achilles tendon injuries? Today we will talk about this aspect of the problem. First, the Achilles tendon is the most vulnerable part of the body’s largest tendon, the main function is to fix the ankle joint when standing, in walking, running, jumping when the heel. One end of the tendon is the belly of the gastrocnemius and hallux valgus muscles, and the other end is fixed to the heel tuberosity. The blood supply is extremely poor in the area 2-6cm above the Achilles tuberosity, and Achilles tendon injuries occur in this area. Second, the most prone to Achilles tendon rupture action When the foot is stepping down, there are calf triceps, posterior tibial muscle, peroneus longus and shortus, flexor toe muscle group in play. But in the whole process, each muscle group has different responsibilities, when the foot in the dorsal extension 20 ° -30 ° angle and then force down the pedal, the calf triceps muscle is the main force. At this time, the Achilles tendon is in a state of extreme tension, other muscle groups are relatively relaxed, if the sudden force, the Achilles tendon is most likely to rupture. Third, the factors leading to the rupture of the Achilles tendon often carry out a lot of strength jumping, stirrups and other movements, more than the ability to tolerate, so that the Achilles tendon strain, resulting in its nutritional disorders, degeneration, strength reduction. When the movement is not coordinated, or when the force is too strong, the Achilles tendon is prone to rupture. Fatigue causes an abnormal increase in muscle tone, a decrease in elasticity and a breakdown in coordination. Long time no exercise, not only physical quality decline, coordination, flexibility is not good, but also lead to the Achilles tendon tissue in the number of open blood vessels reduced, insufficient blood supply, tissue degeneration, the tensile strength of the Achilles tendon reduced, once the risk of doing strenuous exercise, easy to cause injury. As we age, the number of blood vessels in the Achilles tendon gradually decreases and the blood supply becomes thin, leading to damage to the Achilles tendon. When the Achilles tendon rupture, you can feel the pain of the Achilles tendon, and even hear the “pop” sound, like someone kicked you from behind, or the feeling of being hit by a stone. Fourth, the treatment method after the rupture of Achilles tendon is usually fixed in a plaster cast in plantar flexion of the ankle joint within 48 hours after the trauma. The length of cast immobilization time is determined according to the degree of Achilles tendon tear, usually about 8 weeks. Severe cases should be treated by surgery.
