With the continuous development of modern technology, brain workers and office workers continue to expand, more and more desk workers, resulting in the occurrence of cervical spondylosis increases year by year, gradually becoming an occupational disease tendency. In the past, the onset of the majority of the middle-aged and elderly, but now gradually younger, and become a common disease. 1, the concept of cervical spondylosis and clinical manifestations cervical spondylosis, also known as cervical spine syndrome, for long-term strain on the neck and other reasons caused by cervical intervertebral tissues and bone and joint degenerative pathology gradually occur and a variety of clinical symptoms. Initially, the intervertebral disc degenerates, decreases in elasticity, and narrows the intervertebral space by convexity in all directions, followed by a series of changes such as osteophytes at the anterior and posterior edges of the vertebral body, hyperplasia of the vertebral joints, changes in the relationship between small joints, vertebral subluxation, narrowing of the upper and lower diameter and anterior and posterior diameter of the intervertebral foramen, hypertrophy and degeneration of the ligamentum flavum, calcification and ossification. Clinically, osteophytes at the anterior edge of the vertebral body are rarely clinically significant, but those at the posterior edge can protrude into the intervertebral foramen, and osteophytes can encroach on the outlet of the foramen from the front. Both of these are causes of nerve root symptoms. The posterior longitudinal ligament and its surrounding tissues are edematous, fibrotic, calcified, and chondrogenic, and the mixed protrusions can laterally irritate or compress the vertebral artery traveling in the transverse foramen, resulting in a series of phenomena of inadequate blood supply to the vertebral artery. Sympathetic symptoms are produced when sympathetic nerve fibers inside and outside the vertebral canal are stimulated. Depending on the location of the lesion, the compressed tissue and the severity of the compression, the clinical manifestations are different and can be broadly divided into neurogenic, spinal cord, vertebral artery and sympathetic nerve types, and the symptoms are often mixed between each type. 2, the causes of cervical spondylosis and preventive measures 2.1, long-term ambulatory work of various types of personnel 2.1.1, the pathogenesis of academics, teachers, scientists, accountants, computer operators, prolonged head-down work, the neck is too flexed so that the muscles and joints in a state of rigid tension, sudden changes in position so that small joint dislocation, soft tissue injury, local tissue bleeding, swelling, adhesions involving the vertebral body, the occurrence of Degenerative disease, cervical spine injury and lack of vitality of the neck brake, resulting in the gradual development of the disease, head and neck, shoulder pain and discomfort, followed by numbness, muscle atrophy; in severe cases, pain is intolerable, activity is limited, and serious lesions occur. 2.1.2. Preventive measures Pay attention to the adjustment of neck posture and maintain the physiological curvature. Avoid prolonged head-down or head-up work at work or in life to reduce excessive stretching of neck tissues and reduce neck injury. The effective way is to strengthen the whole body and neck exercise, increase the interval exercise, recess exercise or self-exercise and activities for the neck. Moderate relaxation of muscles and improve the regulation of strain to increase the cervical balance stability. 2.2, sleep factors 2.2.1, pathogenesis Many people like to use high pillows, soft beds, often make the neck suspended, not only destroying the physiological curvature of the spine, but also will certainly increase the tension of the soft tissue muscle ligaments of the neck, this state, no less than the cervical spine parts of the daytime low curvature of the ambulatory state, over time in the unconscious state of continuous stretching cervical spine, resulting in chronic fatigue, can not protect the neck The muscles can be fully rested. 2.2.2, preventive measures Adequate mattress and pillow are the key conditions for the prevention and treatment of cervical spondylosis. Too hard or too soft mattresses and pillows are not beneficial to the maintenance of the neck, and it is generally considered better to use slow rebound polyester material, that is, zero pressure foam, or pillow cores with drug fillers, etc. It can fully release the body’s downward pressure and help the neck to fully relax. The neck should be placed on the pillow to sleep, do not let the neck dangling. The height of the pillow should vary from person to person, generally 8 to 375px, or according to the formula: (shoulder width – head width) ÷ 2. In addition, the sleep position is also important, it is best to use the side or supine position. The neck, chest, waist and spine are kept in natural flexion, so that the whole body muscles can relax, adjust the joints and recover from fatigue. 2.3, greedy for coolness 2.3.1, pathogenesis of summer air conditioning temperature is too low or wearing bare back and bare shoulders blowing cold wind, resulting in a long period of cold state of the neck, the back of the neck cold Qi gathered, poor circulation of Qi and blood, stagnation of meridians, blood flow slowed down, local meridians blocked, resulting in changes in the function of the neck muscles, joints and disease. 2.3.2. Preventive measures Pay attention to the warmth of the neck in winter, air-conditioning in summer should be adjusted to the appropriate temperature, the temperature should not be too low, do not want to be cool for a while too little clothing, bare neck and shoulder straight blowing air conditioning. Strengthen physical fitness and neck and shoulder exercise. Natural sweating in summer can not only excrete the toxins in the body, but also promote the blood circulation in the neck and shoulders. 3.Summary Acquire scientific knowledge, strengthen physical exercise, change bad habits, master the general knowledge of cervical spine maintenance, and understand the causes of cervical spine lesions. When the neck is stiff and uncomfortable, painful, even accompanied by finger numbness, dizziness, shoulder sinking and other symptoms, timely medical consultation, early diagnosis and comprehensive treatment. You can choose to use a variety of methods, such as physical therapy, tui na, massage, closure, traction, medication or surgical treatment. Pay attention to the comparison and choose the method that is effective for you.
