Many people may not know how many crestal vertebrae a person has in total, but they are familiar with crestal disease because cervical pain, lumbar pain, and even the resulting headaches and leg pain, plague most people every day. According to statistics, globally, about 5.4 million people in the United States are afflicted by crepitus each year; the average number of days per 1,000 men in the United Kingdom who are unable to work because of the disease is 627 days per year, compared to 347 days for women. In China, about 80% of the population has a history of low back pain or leg pain to varying degrees. According to a survey conducted by the Professional Committee for the Prevention and Treatment of Orthopedic Diseases of the China Healthcare International Exchange Promotion Association, the incidence of crestal spondylosis among young and middle-aged people is rising rapidly: among people aged 30-40, 59.1% suffer from cervical and lumbar spondylosis; among people aged 50-60, the incidence reaches 71%; and among people aged 60 and above, the incidence up to 82%. What is wrong with our spine? Crestal spondylosis has a lot to do with people’s lifestyles, and people cannot always be passively troubled by crestal spondylosis; they should take the initiative. And the earlier you understand the crestal spine, the earlier you can prevent it, the lower the incidence will be. There are 26 crestal vertebrae in a person, of which, 1-7 are cervical vertebrae. Among all the crestal vertebrae, the cervical vertebrae have the greatest mobility and are the most prone to strain injury. Coupled with factors such as long hours of low work, incorrect lifestyle and pillow use, cervical spondylosis has increasingly plagued people, with the most prominent manifestations being shoulder and neck pain, upper and lower limb numbness, dizziness, tinnitus, nausea, palpitations, etc. Among the 7 cervical vertebrae, the 1st, 2nd and 7th vertebrae have the most special shape. The atlantoaxial vertebra, as the first cervical vertebra, and the occipital bone form the strongest and most stable joint of the human body with the help of ligaments, firmly fixing the big head loaded with wisdom. And the second section of the pivot and atlantoaxial vertebrae form the joint, is the best flexibility of the joints of the crestal spine, we have to twist the head, mainly by it. However, flexibility is good, but stability is poor, and the atlantoaxial joint is easily damaged in case of trauma. For example, many people will unknowingly fall asleep when riding in a car, once the emergency brake, the head in the absence of a pivot point, the most likely to be injured is the atlantoaxial joint. The 7th cervical vertebra, called the major vertebra, has a spine that is an important bony landmark on the body surface. Although these cervical vertebrae are prone to injury, common cervical spondylosis has nothing to do with them, but is mainly manifested between the 3-6 vertebrae, because lowering and lifting the head is the main task of these 4 cervical vertebrae. Many people can not imagine that the cervical spine daily joint activities up to hundreds of thousands of times, such a large “workload”, it is easy to form degenerative lesions. For example, prolonged head down will cause fatigue and spasm in the neck muscles, and repeated spasms will eventually lead to straightening or even lordosis of the cervical spine, forming the “office disease” that plagues many people today. For cervical spondylosis, people do not understand that there are many prevention misconceptions, for example, some people think that shaking their heads and twisting their necks can relieve cervical pain, in fact, these actions increase the “workload” of the cervical spine, increasing the wear and tear of the joints, so it is completely wrong. Exercising the neck muscles is the most operational and effective way to prevent cervical spondylosis, and the right way is to follow the “resistance” principle. When exercising, you should do it in the opposite direction of the usual forward-flexed posture, such as leaning back, or exercising “flying swallow and spreading wings”. In addition, will not pillow pillow is also a common cause of cervical spondylosis. The shape of the pillow, the placement of the position, the height, as well as not pillow and other habits may cause cervical spondylosis, so that the cervical spine is still in a forward bending state during sleep. The best way is to place the pillow at the back of the neck, not under the back of the head. The pillow should not be too high or too low to match the physiological curvature of the individual. Thoracic spine, maintaining balance is the safest The thoracic spine accounts for sections 8-19 of the crestal spine. The 12 thoracic vertebrae and 12 ribs form a “cage” that protects the heart, lungs and other important organs. This stable structure makes the thoracic spine less at risk of injury in daily life. The most vulnerable injuries to the thoracic spine are those caused by misalignment of the thoracic joints due to heavy physical work. In addition, there is also thoracic crestal scoliosis, which is prone to occur in adolescents. Prevention of thoracic spine injury, the most critical is to maintain body “balance”. Whether it is work or sports, the body to the side of the most prone to thoracic spine injuries. For example, playing tennis or badminton, are mainly one-armed sports, with the right arm of the thoracic spine right skew, with the left arm of the thoracic spine left skew, especially prone to upper thoracic spine strain injury. For manual laborers and the elderly, the thoracic spine is prone to injury, should usually play less ball, more swimming, running and other sports. Young people who love to play ball, it is best to do more after playing a few balance posture, the thoracic spine health care has a very good role. Second, is the sleeping posture. Old rushing side lying, easy to make the thoracic vertebrae due to strain and lead to dislocation; old half supine or half prone, it is easy to happen thoracic vertebrae left and right rotation type dislocation. The best sleeping position is to sleep on your back and left and right side, so that the thoracic spine to maintain balance. For people with scoliosis, pay more attention to protecting the thoracic spine, avoid carrying heavy shoulder bags, girls try to wear high heels, sitting and walking posture should be upright and upright. Lumbar vertebrae, the most “tired” vertebrae Lumbar vertebrae in the 20th-24th section of the crestal vertebrae, they can be considered the most “tired” vertebrae in the entire crestal column. It does not have the stability of the thoracic vertebrae, no cervical vertebrae flexible, but bear the weight of the entire upper body, no matter which direction the body twists, the force is the waist, which makes it a much higher chance of injury. Looking at the crest from the side, it is wavy and has four physiological arcs: the neck is convex forward, the chest is convex backward, the waist is convex forward, and the sacrum is convex backward. In these physiological curves runs a gravitational line. Therefore, the lower the position of the 5 lumbar vertebrae, the heavier the load, the higher the risk of disease. Damage to the intervertebral disc, known as the “shock absorber,” is the most common. Most of the lumbar spine disease is “sitting” out. The survey shows that often sitting in front of the computer “white-collar” and drivers, is the highest incidence of lumbar disc herniation. The person is sitting at 20 degrees forward, the disc is under the most pressure. When you feel a vague pain in your back, you have often formed an accumulative injury. In the clinic, long-term chronic back pain, about 35% will eventually develop into lumbar disc herniation. 1, to protect your waist, the first thing to avoid sedentary, feel the waist pain, get up and walk, stretch, relieve and then continue to work. Seat is best with a backrest, or put a small cushion pillow in the back, so that it can slightly top the waist, which can keep the waist straight, so that the waist muscle fully relaxed. Choose a table is also very learned, it is best to choose the front of the high and low, the desktop tilt, can reduce the degree of work when the waist bent forward. In addition, lying in bed to read a book is not good for the eyes, but the waist rest is beneficial. People with back problems, you can choose appropriately. 2, when standing directly bent over to take heavy objects, is a mistake that many people are prone to make. The correct approach is to squat first and then pick up the items, the weight on the leg muscles, can reduce the pressure on the lumbar spine. 3, bed and sleeping position are important. Many people know that the waist is not good, to choose a harder bed, but in the sleeping position on the freedom to let go. In fact, the best sleeping position for lumbar protection is to sleep on your side, with your lower limbs slightly bent. If you like to sleep on your back, can be a pillow under the knee, which is what the ancients called “sleep like a bow”. This sleeping position is most conducive to lumbar muscle relaxation, reduce the pressure within the intervertebral discs, so that the lumbar spine to obtain adequate rest. In addition, there is the sacrum and tailbone, the former mainly to enhance the pelvic strength, the two are prone to traumatic bone fractures or fractures, usually also need to pay attention to protection.
