The corresponding clinical symptoms and signs are caused by degenerative changes of the cervical intervertebral disc and its secondary degenerative changes of the intervertebral joints resulting in the involvement of the adjacent tissues (spinal cord, nerve roots, vertebral artery, sympathetic nerves). Significant degeneration of the cervical vertebral segments is a clinical manifestation of cervical vertebral wedge compression fractures. The differential diagnosis of significant degeneration of the cervical vertebral segment: bone spur formation at the posterior edge of the vertebral segment degenerative disc degeneration is one of the manifestations of cervical spinal stenosis, congenital developmental cervical spinal stenosis is caused by fetal spinal canal hypoplasia, resulting in narrowing of the sagittal diameter of the cervical spinal canal, resulting in irritation or compression of the spinal cord and spinal nerve roots, resulting in a series of clinical symptoms. Chance fracture can be clearly identified by lateral X-ray examination of the damaged area and the degree of vertebral segmentation. Neurogenic cervical spondylosis Cervical rib and anterior oblique muscle syndrome, extramedullary subdural tumors in the spinal canal, neurofibromas in and around the intervertebral foramen, and tumors near the pulmonary apex can cause upper extremity pain, neuropathic myasthenia, angina pectoris, and rheumatic polymyalgia. Spinal cord type cervical spondylosis Amyotrophic lateral sclerosis, multiple sclerosis, intravertebral canal tumors, and spinal cord cavity. Vertebral artery type cervical spondylosis needs to be differentiated from other causes of inadequate blood supply to the vertebral basilar artery, such as atherosclerosis and developmental anomalies of the vertebral artery. Vertebral arteriogram is the most reliable method of differentiation. Sympathetic cervical spondylosis Inadequate coronary artery supply, neurosis, menopausal syndrome, vertigo due to other causes. Esophageal compression cervical spondylosis should be differentiated from dysphagia caused by esophagitis and esophageal cancer. Cervical cervical spondylosis and chronic cervical soft tissue injury Because of long-term low head work, the head is often in a forward-flexed posture, so that the cervical intervertebral disc is compressed in front and the nucleus pulposus moves backward, stimulating the fibrous ring and the posterior longitudinal ligament, resulting in uncomfortable symptoms.
