Currently. Adolescents suffering from “cervical spondylosis” is not uncommon in orthopedic clinics. As adolescents spend a long time studying, working and using electronic products with their heads down, or using pillows that are too high, the head and neck are fixed in a forward-flexed position for a long time, resulting in continuous contraction of the anterior cervical flexors and passive stretching of the posterior cervical extensors for a long time, without timely rest and adjustment, over time, the stretching and contraction function of the neck muscles will gradually weaken and the muscle strength will be reduced, and the ligaments will relax and degenerate due to the lack of regular activities. Chronic neck discomfort and even acute neck pain can occur. To effectively prevent “cervical spondylosis” in adolescents, please pay attention to the following aspects: 1, first of all, avoid the above-mentioned triggering factors. Attention should be paid to maintaining the correct posture of the head and neck and correcting bad habits and posture. Hold the head not too far forward, while avoiding a long time in a position. When studying about 30 minutes to do a self-exercise exercises of the neck, gently move the neck. 2, sleep posture has a great impact on causing cervical spondylosis, during sleep. The pillow height should be suitable for individual body type. Make sleep to keep the head is located in a slightly backward position, in order to make the cervical spine around the tension of the ligaments and muscles to get sufficient rest. So the pillow is too high or no pillow is not correct. 3, adolescents usually live and study and sports activities, should pay attention to self-protection. In summer, avoid prolonged stimulation by the cold wind of air conditioners or fans, and pay attention to keeping the neck warm in winter. 4, for adolescents who have developed cervical spondylosis, the first thing is to correct bad posture habits, acute pain patients can consider using the occipital jaw set traction or cervical brace fixed brake, local wet heat compress, it is not easy to do neck exercise at this time. Patients whose symptoms cannot be relieved for a long time need to seek further medical examination or hospitalization. The author believes that simple neck discomfort caused by poor posture cannot be labeled as cervical spondylosis at present, so the term “cervical spondylosis” is used.
