Many patients with cervical spine discomfort come to the clinic and Dr. Luo has them take a cervical spine X-ray. Many patients, especially young people who love to play with cell phones and work with computers, often see this phrase on the report: “cervical spine physiological curvature straightening”. What does this mean exactly? The neck appears to be straight when viewed from the side while sitting or standing, but in fact the seven vertebrae of the cervical spine are arranged to form a physiological arc that projects forward. The maximum distance from the highest point of the arc to the straight line is the value of the physiological curvature of the cervical spine. The normal range is approximately within 12 (±5) mm. In medicine, this forward curved projection is referred to as the physiological curvature of the cervical spine. Through the cervical spine image on X-ray: traveling 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 prolonged strain, lack of cervical spine activities, spinal injury, spinal calcification, etc. will cause the cervical spine physiological curvature to straighten. The existence of cervical physiological curvature can increase the elasticity of the cervical spine, reduce and cushion the gravitational shock from the foot, and prevent damage to the spinal cord and brain. As a result of long-term sitting, poor sleeping posture and disc nucleus pulposus dehydration degeneration, the anterior convexity of the cervical spine can gradually disappear, or even become straight or bent backwards, i.e., 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 spine physiological curvature straightening is very closely related to the way of life, so in order to avoid this symptom, we should pay attention to avoid some bad habits and work posture. Under normal circumstances, the human cervical spine is showing a certain curvature, specifically the forward projection, but due to the role of some adverse external factors, it is easy to lead to the emergence of cervical physiological curvature straightening. These undesirable external factors mainly include acute neck sprain and myofibrillar tissue inflammation of the neck and shoulder. In modern society, with the popularity of internet and computers, as well as the use of smart phones, the number of patients with straightened cervical curvature is increasing. Dr. Luo often jokes with his patients that “the popularity of the Internet and smartphones has brought us unlimited business opportunities.” In addition, prolonged poor sitting posture and exposure to cold can cause myofibrillitis in the neck and shoulders, causing muscle spasms due to pain. Painful symptoms caused by inflammation of joint capsule, ligaments and small joints can also reflexively cause the relevant neck muscles to spasm to protect the affected joints, so the spasm of neck muscles can cause the physiological curvature of the cervical spine to straighten. In the acute stage of neurogenic cervical spondylosis, because the affected small joints are acutely inflamed, the joint periosteum and joint capsule are swollen, 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. This requires everyone to do their best to avoid in daily life. Avoid a long-term posture at work, and use the computer in moderation. Work for life, but life is not just for work. A good body is the top priority, to distinguish the main priority. Disease hazards: 1, reduces the shock absorption effect on the head. 2, causing head, neck, shoulder, back, arm pain, neck and neck stiffness, restricted movement. 3, causing dizziness, spinning, vomiting in severe cases these are common symptoms. 4.It may cause numbness of the hand (neurogenic cervical spondylosis) and neck pain and discomfort due to compression of the nerve root, and in more serious cases, dizziness, blurred vision, nausea, walking vertigo and other symptoms. 5, some patients will also be accompanied by hypertension or high and low blood pressure, abdominal contraction, decreased appetite and panic, poor sleep, neck and back pain, upper limb weakness, numbness of the fingers, dizziness, nausea and even blurred vision, swallowing blurred, etc. Preventive care: 1, choose the right pillow. The right pillow has important significance for prevention and treatment. General supine pillow height of a fist, side sleepers pillow height of a fist and a half, about 10 cm or so. The pillow core filling should be appropriate to maintain a certain amount of hardness and elasticity. The elasticity of the pillow is too large 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 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 sloping work board with the desktop is 10 to 30 degrees, more conducive to the adjustment of sitting posture. The second is that about 1 to 2 hours, purposefully let the head and neck to the left and right several times, the rotation should be gentle, slow, in order to achieve the maximum range of motion in this direction shall prevail; or line of shoulder exercise, two shoulders slowly tighten for 3 to 5 seconds, then both shoulders up to adhere to 3 to 5 seconds, repeat 6 to 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 to 5 times.
