Significant degeneration of the cervical vertebral segments is due to longitudinal forward flexion and compression violence. In addition to the general symptoms of a cervical spine injury, the patient’s main manifestation is a forced cervical position, difficulty raising the head, and pressure pain at the small posterior joints. If the compression is severe, or if the spinal canal is narrowed, or if the cervical vertebral segments have been significantly degenerated, there can be severe symptoms of spinal cord or spinal nerve root involvement, which should be carefully examined to determine the extent of the condition. The main symptoms are neck and back pain, upper limb weakness, numbness of fingers, weakness of lower limbs, difficulty in walking, dizziness, nausea, vomiting, and even blurred vision, tachycardia and difficulty in swallowing. The clinical symptoms of cervical spondylosis are related to the location of lesions, the degree of tissue involvement and individual differences. Nerve root type cervical spondylosis 1. It has more typical radicular symptoms (numbness and pain), and the scope is consistent with the area innervated by the cervical spinal nerve. 2.Positive head press test or brachial plexus pull test. 3.The imaging findings are consistent with the clinical presentation. 4.No significant effect of painful point closure. 5.Except for extra-cervical spine lesions such as thoracic outlet syndrome, carpal tunnel syndrome, elbow tunnel syndrome, frozen shoulder syndrome and other disorders caused by pain in the upper extremity. Spinal cord type cervical spondylosis 1. Clinical manifestations of cervical spinal cord damage are seen. 2.X-ray film shows osteophytes on the posterior edge of the vertebral body and spinal stenosis. The presence of spinal cord compression is confirmed by imaging. 3.Except amyotrophic lateral sclerosis, spinal cord tumor, spinal cord injury, multiple peripheral neuritis, etc. Vertebral artery type cervical spondylosis 1. There have been episodes of sudden collapse. With cervical vertigo. 2. Positive rotation neck test. 3.X-ray shows segmental instability or osteophytes of the cardinal joints. 4.More often accompanied by sympathetic symptoms. 5.Except ophthalmogenic and otogenic vertigo. 6.Except for insufficiency of basilar artery supply caused by compression of vertebral artery segment I (the segment of vertebral artery before entering the transverse foramen of cervical 6) and vertebral artery segment III (the segment of vertebral artery before exiting the cervical spine into the skull). 7. Vertebral arteriogram or digital subtraction vertebral arteriogram (DSA) is required before surgery. Sympathetic cervical spondylosis Clinical manifestations include a series of sympathetic symptoms such as dizziness, blurred vision, tinnitus, hand numbness, tachycardia, precordial pain, etc. There is instability or degeneration of the cervical spine on X-ray. Vertebral arteriogram is negative. Esophageal compression type cervical spondylosis Cervical vertebrae with anterior bird’s beak-like hyperplasia compressing the esophagus causing dysphagia (confirmed by barium examination of the esophagus), etc. Cervical cervical spondylosis Cervical cervical spondylosis, also called localized cervical spondylosis, refers to pain and corresponding pressure points in the head, shoulders, neck and arms. There are no obvious degenerative changes such as narrowing of the intervertebral space on X-ray, but there can be changes such as changes in the physiological curve of the cervical spine, intervertebral instability and mild osteophytes.
