If not for the cartoon pattern on the school bag, it is difficult to distinguish what the difference between these student bags and luggage. Even the student bags are available with trolley. This “small body, big bag” learning style of elementary school students is worrying. In orthopedic clinics, there is a high trend of cervical spondylosis in adolescents. Cervical spondylosis is a syndrome in which degenerative lesions of the cervical spine compress the spinal cord, nerves, blood vessels, etc., causing a series of symptoms in the head, neck, limbs and internal organs. Young students and many young people engaged in accounting, drivers, computers and other occupations, mahjong obsessed people spend a long time studying or working in front of the computer, reducing activity, causing fatigue and strain on the neck muscles, resulting in poor local blood circulation, dizziness, headaches and other symptoms of cervical spondylosis. Meanwhile, staying in an air-conditioned room for a long time in summer and sleeping in an incorrect posture can cause neurovascular spasm and muscle discomfort in the neck. After the film is taken, the physiological curvature of the cervical spine becomes straight or reverse arch, and the cervical spine degenerates prematurely, so it is not uncommon to see “people in their teens and cervical spine in their forties” clinically. Of course, some people do not have obvious changes in the film, belonging to the soft tissue injury of the neck, although not strictly speaking, cervical spondylosis. However, if you do not pay attention to physical exercise, do not pay attention to correct the poor lifestyle, over time, can be transformed and enter the ranks of cervical spondylosis patients in advance. We strongly urge young people to establish the concept of “care for the spine, happiness for life”.
