An orthopedic surgeon once said that the cervical spine is the defect of God’s creation, because the slender cervical vertebrae hold the most important head. However, people in this era have got cervical spondylosis because of the small cell phone. What is the cervical spine like? The cervical spine is the smallest of the spinal vertebrae, but has the greatest flexibility and the highest frequency of movement. Each section of the cervical spine consists of a vertebral body, a vertebral arch and seven protuberances (a pair of spinous processes, a pair of transverse processes, two pairs of articular processes), between the ligaments, intervertebral discs connected to form the cervical spine. Second, the cervical spine can not bear the weight When the head is perpendicular to the cervical spine, the muscle tension is 0, the cervical spine is subject to all the pressure from the weight of the head itself; and when the head down 15 degrees, the cervical spine is subjected to pressure for the cervical vertebrae vertically under the pressure of 2 times; in the angle of 45 degrees, the cervical vertebrae are subject to pressure also increased to the vertical when the 3.7 times; if the angle of the head down 60 degrees, the cervical vertebrae under The pressure of the cervical spine is 4.5 times the vertical load bearing. Third, the low head of the cervical spine seems to reduce the life expectancy of 20 years Normal 40 years of age or older men, 45 years of age or older women about 90% of the existence of cervical vertebrae bone spurs, generally 5, 6, 7 cervical vertebrae degradation. However, nowadays, the low head of the people every day to read the news, watch videos, brush the circle of friends, play games, read novels …… long time 4, 5, 6 section of the cervical vertebrae pressure accumulated deformation, the intervertebral interval narrowing, produce bone spurs, compression of nerves, it looks like the cervical spine old 20 years! Mild cervical spondylosis: shoulder and neck stiffness and soreness, head down to play the cell phone will make the cervical spine pressure suddenly increased, long time to maintain a posture will also affect the blood supply to the head, cervical spondylosis will be the initial neck pain, shoulder stiffness, numbness of the fingers, generally can be relieved after resting, and is not taken seriously. Moderate cervical spondylosis: headache, dizziness, tinnitus, nausea With osteophytes, the intervertebral discs become narrower, the cervical spine is gradually degenerating and destabilizing, and the low head people show a series of sympathetic symptoms such as dizziness, dizziness, tinnitus, numbness of the hands, tachycardia, and pre-cardiac region pain. Severe cervical spondylosis: walking difficulties, paralysis When the low head people feel lower limbs numbness, pain, limping, walking as if stepping on cotton, cervical spondylosis has been very serious. Allow the development to continue will be out of control of urination and defecation, paralysis. Fourth, save the low head 1, increase other interests, reduce the frequency of cell phone use, use time. 2, play the cell phone, every 30 minutes to rest. 3, the cell phone set mute, regular view. 4, do cervical spine exercises.
