A herniated cervical disc is a relatively common cervical and lumbar spine condition in life. Most cervical disc herniation is a chronic attack that can start without any symptoms, with slow degenerative changes in the cervical spine that occur with increasing age, and later some patients will have symptoms of nerve or spinal cord damage that require surgery. The occurrence of this disease has brought a lot of trouble to everyone’s normal life, so we should pay attention to cervical disc herniation, so today we will explain in detail what are the causes of cervical disc herniation? 1, in the development of cervical disc herniation, chronic strain is the primary culprit, long-term local muscle, ligament, joint capsule injury, can cause local hemorrhage edema, inflammatory changes, gradually appear in the lesion site inflammatory mechanization, and the formation of osteophytes, affecting the local nerves and blood vessels. 2, trauma is a direct factor in the occurrence of cervical disc herniation. Often, people already have varying degrees of lesions before trauma, which puts the cervical spine in a highly dangerous state, and trauma directly induces the occurrence of symptoms. 3, bad posture is another major cause of cervical disc lesions. Long hours of low work, lying in bed watching TV, reading books, like high pillow, long hours of computer operation, violent rotation of the neck or head, sleeping in a moving car, these bad posture will make the neck muscles in a long-term fatigue state, prone to injury. 4, cervical spine dysplasia or defects is also one of the causes of cervical disc herniation can not be ignored, Asian species compared to Europeans and Americans, the volume of the spinal canal is smaller, more prone to spinal cord compression, resulting in symptoms. In patients with unilateral vertebral artery deficiency, the incidence of vertebral artery type cervical spondylosis is almost 100%, and the difference is only a matter of time. 5, age factor: as we grow older, the wear and tear of the human body parts is increasing, the cervical spine will also produce a variety of degenerative changes, and degenerative changes in the intervertebral disc is the most critical cause of cervical disc herniation. 6, in addition, skull base depression, congenital fused spine, root canal stenosis, small spinal canal and so on are congenital developmental abnormalities, is also an important reason for the occurrence of this disease.
