Write in front: A pair of normal, healthy feet is the cornerstone of human walking. With the modernization of life and work, more and more people are concerned about the health of their feet and ankles, and it has become an integral part of modern women’s pursuit of beauty. Humans are the only animals in the world with the structure of the foot arch, the foot is a very fine part of the human body, although it does not account for a large proportion, but has a quarter of the human body’s bone number; in addition, the foot above there are 66 joints and 40 muscles and more than 200 ligaments, a 70Kg weight in the flat walk each foot needs to bear and send 3 times the weight of the thrust to jogging needs 5 times the weight of the thrust, and jumping needs 6-8 times the weight of the thrust! To jog requires 5 times the thrust of body weight, while jumping requires 6-8 times the thrust. And the five organs in the human body and the acupuncture points on the feet have inseparable relative projection relationship, unsuitable shoes will not only cause foot disease, but also may trigger including the brain, spinal cord, heart, digestive circulatory system, joints and other parts of the whole body disease. However, at present, most people are limited to diseases with obvious signs, often ignoring the attention to foot health, and there are many misconceptions about foot disease and its prevention and treatment. Whenever I see a lot of patients come to the clinic, a foot and ankle disease is not serious because of the loss of treatment and cause the patient’s own pain as well as a huge economic loss, the author is heartbroken, sigh of regret. In order to let you have a basic understanding of the common diseases of the foot and ankle, may cause foot and ankle diseases of bad habits of correction, now will be the basics of foot and ankle disease is presented for your reference. (a) “Ankle sprain” should not be taken seriously: the medical term “ankle ligament injury” is a common injury in life or sports, which can lead to ankle fracture in serious cases. For people without fracture, generally pay insufficient attention, not to be correctly fixed, functional exercise, acute swelling, pain subsides, most people carry on normal life and work, and some even start strenuous activities, which leads to “sprained foot” recurrence, repeated swelling and pain. “Because I can move around, therefore, it is impossible to have a fracture”; “I can still walk, there is no need for immediate treatment” “If there is a foot and ankle trauma, you should immediately give hot compresses” and so on are not correct. incorrect. Because the structure of the foot and ankle joint is very strict, not only to meet the walking, working range of motion, but also to maintain stability in the activities, the surrounding ligaments play an important role. If the ligaments do not recover well from the injury, it can lead to ankle pain syndrome, talus osteochondral injury, chronic synovitis of the ankle joint, tarsal sinus syndrome and even functional instability of the ankle joint. Therefore, when the “broken foot”, should be immediately braked, the application of ice packs to prevent swelling, will be wrapped in a towel bag of ice, around the injured area. Generally, each cold compress 20 minutes, 40 minutes after the cycle once. The injury is simply fixed with an elastic bandage, however, the bandage should not be too tight, so as not to affect the blood flow to the distal end of the limb, resulting in necrosis of the tissue or limb. Elevate the affected limb by placing the injured ankle above the heart, which will reduce swelling and relieve pain. Consult a medical professional for treatment options. In general, even in the absence of bony damage, immobilization in a mobility brace with functional exercises is still recommended.
