Core tip: lumbar disc herniation, originally an “adult disease”, but Nanping, a 15-year-old boy, but by its torment: walking staggering, sometimes even unable to walk. The cause of the disease is the boy 9 years old addicted to the Internet, sitting in front of the computer every day is three or four hours. Chen Chunmei, chief physician of neurosurgery at Fujian Medical University Union Hospital, warned that many people play with cell phones and computers, attention is highly concentrated, rarely get up and walk around, or change positions. Once sedentary, long time head down, it is easy to appear neck and waist pain, prolonged delay, cervical and lumbar spine will be lesions, serious paraplegia may result. Internet three or four hours a day, suffering from lumbar disc herniation The spine is the human body’s “pillar”, nowadays, cervical and lumbar spondylosis has become a common disease, the incidence of which is second only to the flu, adult cervical and lumbar spondylosis incidence rate of 30%, respectively, 80%. Last Friday was the World Spine Day, the Department of Neurosurgery of Union Hospital of Fujian Medical University and Fujian Institute of Neurosurgery, jointly established the Fujian Cervical and Lumbar Spine Health Club. Xiaowei, a boy from Nanping who had suffered from a herniated lumbar disc, came to the scene to talk about his painful experience. Last year, Xiaowei was carried into Concordia Hospital by his mother when he became ill. “When he arrived at the hospital, he walked shakily and sometimes couldn’t even walk.” Chen Chunmei, director of neurosurgery at Concordia Hospital, said that upon examination, Xiaowei had a herniated lumbar disc that had pressed on the nerves and had to be operated on. Xiaowei’s mother, Ms. Chen, said Xiaowei was addicted to the Internet at the age of 9, when he was in third grade, three or four hours a day sitting in front of the computer, after junior high school Xiaowei often shouted back pain. “At first we thought it was a small thing, did not care.” Until once Xiaowei fell down on a bike, waist can not stand upright, even can not walk normally, his family sent him to the hospital for a checkup, only to know that he was a young age suffered from lumbar spondylosis. Dr. Chen Chunmei, the chief doctor, said that Xiaowei’s waist has been in a bent position for a long time, resulting in the lumbar spine bending forward and the intervertebral discs being pressurized for a long time. We recommended that he undergo minimally invasive surgery to remove the lumbar vertebrae that were compressing the nerves. Two weeks after the successful surgery, Xiaowei will be able to resume his daily life and can also participate in normal physical education courses and exercise. Head down 60 degrees, equivalent to the cervical spine hanging two large watermelon people who just look down at the phone, known as “low head”. According to the survey, low head in the crowd accounted for more than 60% of the proportion, when these low head of the people addicted to the phone but ignored a point, their spine. “Looking down at the cell phone, the weight borne by the cervical spine is three times that of when it is vertical.” Dr. Chen Chunmei, chief physician, said that when playing with a cell phone, if the posture is not proper, it may make your cervical spine bear as much as 27 kilograms of weight, which is heavier than a 7-year-old child. Dr. Chen Chunmei, chief physician, explains that the force on the cervical spine consists of two parts: one is the weight of the head itself, and the other is the force generated by the stretching of the muscles. Therefore, the force on the cervical spine varies with the angle of the head. Since the weight of the head is constant, the force on the cervical spine comes from the tension generated by the muscles. When the head is vertical, the muscle tension is zero. The greater the angle of the head droop, the greater the muscle tension, and when the head is lowered more than 45 degrees, the force on the cervical vertebrae is 3.7 times the force when it is vertical. However, in real life, people bow their heads at an angle much greater than 45 degrees, even higher than the maximum value of cervical spine bending 60 degrees, then in this case, the cervical spine is subjected to pressure equivalent to the cervical spine hanging two large watermelons. The longer the low head time, the greater the cervical spine disc pressure, the greater the damage, the older the age, the greater the damage to the human body’s nerves, blood vessels, spinal cord. Morbidity is second only to the flu, and prolonged delay may lead to paraplegia Chen Chunmei, chief physician, said that the health of the spine is directly related to the cervical spine, lumbar spine and other bones and nerves, blood vessels and other health. Cervical and lumbar spondylosis is mainly a disease of middle-aged and old age, but today there is a clear trend of rejuvenation. “The onset of this disease is related to occupation and lifestyle habits.” Chen Chunmei, chief physician, said that employees of organizations and units that need to be sedentary, drivers, teachers and so on are the high incidence of this disease. Young people who often stay in one position to look at computers and play with cell phones are also prone to this disease. According to statistics, the incidence of adult cervical and lumbar spondylosis is 30%, 80%, the incidence rate is second only to the flu. Prolonged untreated, will eventually develop to spinal cord compression, may cause paraplegia. In addition to low head to play the phone, work, what other habits will lead to cervical and lumbar spondylosis? Chen Chunmei, chief physician, told reporters that, as the saying goes, a high pillow, but a high pillow will make the physiological curvature of the cervical spine straighten or even reverse arch. In addition, sleeping in a soft bed, lying on the sofa or bed reading will lead to cervical and lumbar spine damage. Expert reminder: prevention of cervical lumbar spondylosis less play cell phones, computers “The best way to prevent, is to adjust the alarm clock.” Chen Chunmei, chief physician, said that everyone in the process of work and study, can adjust the alarm clock, forcing themselves to regular activities, which can effectively relieve the pressure of the cervical and lumbar vertebrae. In addition, some other habits of life, can also prevent cervical and lumbar spondylosis. For example, less look at the computer, less play cell phone. Low head time should not exceed 45 minutes, to reach the time to get up and move around. When sitting in a chair, try to let the buttocks to the back of the chair, so that the waist does not hang. Driving as much as possible will be adjusted to the seat relatively straight some, is also to give the waist a support. When you are tired at work, sit at the front of the chair, lean your upper body against the back of the chair, stretch your arms over your head and reach back as hard as you can to make your upper body at a 45-degree angle to the horizontal. This action helps to release pressure on the spine and relieve back pain. Try not to stilt legs, this posture will make people habitually hunch over, which is one of the major causes of back pain. It is best to have both feet slightly open and flat on the ground. When choosing a chair, choose a chair that conforms to the principles of ergonomics, and the curvature of the back of the chair should be consistent with the curvature of the spine. If the chair back is vertical or hard, you can add a cushion to fill the gap between the waist and the chair back. Swimming, more than 200 meters each time, preferably 3 to 4 times a week. Walk backwards, pay attention to the safety of the situation, walking backwards and downwards alternately, the step is to kick the buttocks with the heel. Walk about 500 steps a day.
