What is cervical spondylosis? Cervical spondylosis is a clinical manifestation caused by the deformation and narrowing of the cervical spinal canal or intervertebral foramen due to degenerative changes of the cervical spine, which stimulates and compresses the cervical spinal cord, nerve roots, and sympathetic nerves, causing structural or functional damage to them. According to the pathological changes, cervical spondylosis can be divided into five types: 1, spinal cord type; 2, nerve root type; 3, vertebral artery type; 4, sympathetic nerve type; 5, mixed type. Who is prone to cervical spondylosis? 1, in terms of age, because along with the growth of age, excessive chronic strain on the cervical spine can cause degeneration and weakening of the intervertebral disc, formation of bone spurs at the vertebral body edge, small joint disorders, ligament thickening, calcification and a series of degenerative pathological changes, therefore, more middle-aged and elderly people suffer from cervical spondylosis. 2, occupationally speaking, long-term low desk workers or head and neck often turn in a certain direction is prone to cervical spondylosis. These occupations include office workers, typists, scribes, computer operators, accountants, embroiderers, operating room nurses, long-term microscope viewers, traffic police and teachers. Although the incidence of cervical spondylosis is higher among workers in these occupations. 3, from the sleep posture, because about 1/4 to 1/3 time in a person’s life is spent in bed, when the pillow is too high, too low or pillow parts are not appropriate, bad sleep posture for a long time, sleep time and can not be adjusted in time, easy to cause the vertebral muscles, ligaments, joints balance disorders, the side of the tension is easy to fatigue and produce varying degrees of strain injury. Therefore, people who like to lie on high pillows and have repeated “pillow” history are prone to cervical spondylosis. In addition, lying down to read, watch TV when the head long single posture and other people with too much bad posture in daily life, also prone to cervical spondylosis. 4, patients with a history of head trauma are also susceptible to cervical spondylosis. Cervical spine injuries due to traffic accidents and sports injuries often induce the occurrence of cervical spondylosis. Post-traumatic cervical spondylosis is more common in young people. Such as inappropriate exercise in sports activities, more than the amount tolerated by the neck; military training accidental trauma to the neck caused by a mishap, etc., often leads to the onset of injury after the disc, ligament can not be repaired. 5, Finally, those with congenital deformities of the cervical spine, such as congenital spinal stenosis, congenital vertebral fusion, cervical ribs and hypertrophy of the transverse process of the 7th cervical vertebra, are prone to cervical spondylosis. Inflammation of the throat can sometimes be the cause of cervical spondylosis symptoms.
