1.What is cervical spine physiological curvature straightening? Many patients with cervical spine discomfort come to the outpatient clinic, and after the doctor lets them take a cervical spine photograph, many patients, especially young people, often see such a phrase on the report: “straightening of the physiological curvature of the cervical spine”. What does this mean exactly? From the side, the neck appears to be straight when sitting or standing, but in fact the cervical spine is not straight, but has a physiological curvature that projects forward in its middle section. In medicine, this forward curved projection is called the physiological curvature of the cervical spine. Through the cervical spine image on X-ray: along this curvature, there is a continuous, smooth curved curve formed at the trailing edge of each cervical vertebra, which is medically called cervical curvature. When the incorrect sitting posture for a long time, or long time strain, cervical spine lack of activity, spinal injury, spinal calcification, etc. will lead to cervical spine physiological curvature straightening. 2, the role of the cervical physiological curvature of the cervical spine The existence of the cervical physiological curvature can increase the elasticity of the cervical spine, reduce and cushion the shock of gravity, to prevent damage to the spinal cord and brain. Due to long-term sitting, poor sleeping posture and intervertebral disc nucleus pulposus dehydration degeneration, the anterior convexity of the cervical vertebrae can gradually disappear, or even become straight or bent backwards, that is, backward convexity, which becomes one of the more important diagnostic bases on the X-ray of cervical spondylosis. From the pathological point of view, the appearance of cervical physiological curvature straightening is very closely related to our lifestyle, so in order to avoid this symptom, we should pay attention to avoid some bad habits and work posture. 3, the cervical spine physiological curvature straightening causes Under normal circumstances, the human cervical spine is showing a certain curvature, specifically the forward convexity, but due to the role of some adverse external factors, will easily lead to the emergence of cervical spine physiological curvature straightening. These adverse external factors include acute neck sprain and myofibrillar tissue inflammation of the neck and shoulder. We all want to understand the symptoms of cervical physiological curvature straightening, and understanding this problem will help us to detect it early in the process of early cervical physiological curvature straightening, take effective measures to deal with it in time, and resume normal life early. We need to have a preliminary understanding of the causes of this disease in order to fully analyze the symptoms of this disease. Trauma may induce this disease, but trauma is a factor that can be avoided, many people are due to muscle pain, spasm, pulling on the bones, resulting in the appearance of cervical curvature straightening, so we should pay attention to avoid trauma and other factors in daily life. In addition, due to long-term poor sitting posture, cold and other reasons can cause muscle fiber tissue inflammation in the neck and shoulder, so that the muscle spasms due to pain. Painful symptoms caused by inflammation of joint capsule, ligaments and small joints can also reflexively cause spasm of relevant neck muscles to protect the affected joints, so spasm of neck muscles can cause straightening of the physiological curvature of the cervical spine. In the acute stage of radicular cervical spondylosis, because the affected small joints are acutely inflamed, the joint periosteum and joint capsule are swollen, and the adjacent nerve roots are irritated, the patient mostly has neck and shoulder muscle tension, and the activity is obviously restricted, which can cause the physiological curvature of the cervical spine to straighten. Lesions of the cervical spine, such as tumors, tuberculosis and septic infections of the cervical spine, can cause neck pain, muscle spasm, restricted movement of the cervical spine and straightening of the physiological curvature. These are the reasons that can easily trigger the straightening of the physiological curvature of the cervical spine, which we need to do our best to avoid in daily life. 3.Disease hazards (1) Reduces the shock absorption effect on the head. (2) Stiffness of the neck and restriction of normal activities. (3) Causes chronic cervical spine lesions. (4) Leads to hypertrophy of the ligamentum flavum, injury to the collar ligament, and injury to the muscles associated with the paravertebral body. (5) Some patients may also have hypertension or high and low blood pressure, abdominal contraction, decreased appetite and panic, poor sleep, etc. 4, preventive care (1) choose the right pillow. The right pillow has important significance for prevention and treatment. General supine pillow height a fist, side sleeper pillow height a fist and a half, about 10 cm. The pillow core filling should be appropriate to maintain a certain amount of hardness and elasticity. Too much elasticity of the pillow is easy to cause fatigue and injury to the neck muscles. (2) to prevent trauma and fallen pillow. Usually should prevent neck trauma and pillow, so as not to cervical ligament injury, so that the stability of the cervical spine is damaged, and then induce or aggravate cervical spondylosis. (3) Strengthen the exercise of the neck. Strengthen the neck exercise can prevent and delay the occurrence and development of cervical spine disease. How do office workers work to prevent the cervical spine physiological curvature straightening? The first point is that the best way to cure cervical spondylosis, head posture is very important. In the sitting posture as far as possible to maintain a natural sitting position, head slightly forward to maintain the normal physiological curve of the head, neck and chest; can also raise or lower the height of the desktop and chair ratio to avoid excessive head and neck back or excessive forward flexion; in addition, customize a 10-30 degree sloping work board with the desktop, more conducive to the adjustment of sitting posture. The second is that in 1-2 hours or so, purposefully let the head and neck to the left and right several times, when turning should be gentle, slow, in order to achieve the maximum range of motion in this direction shall prevail; or line shoulder exercise, two shoulders slowly tighten 3-5 seconds, and then both shoulders up to adhere to 3-5 seconds, repeat 6-8 times. The general white-collar treatment of cervical spine physiological curvature straightening method is that we can also use two desks, two hands propped up on the desktop, two feet vacant, head backward, adhere to 5 seconds, repeat 3-5 times.
