Cervical spondylosis is mainly caused by degenerative changes of the cervical spine. Clinically, cervical spondylosis is mainly divided into the following types: cervical cervical spondylosis: mainly manifests as pain and swelling in the head, neck and shoulders, and can be characterized by changes in the physiological curvature of the cervical spine when taking cervical spine X-ray films. Nerve root type cervical spondylosis: mainly due to degenerative changes and osteophytes of the cervical spine causing nerve compression and corresponding symptoms, the most common is numbness and pain of the upper limbs, etc. The pressure neck test or brachial plexus pull test is mostly positive. Spinal cord type cervical spondylosis: It is caused by compression of the spinal cord in the cervical spine due to osteophytes or disc herniation in the cervical spine, which can cause a feeling of tethering in the upper chest and may even cause abnormal walking and abnormal urinary and fecal functions. Vertebral artery type cervical spondylosis: It is likely that the symptoms of insufficient blood supply to the brain are caused by the stimulation of the vertebral artery passing through the cervical spine by factors such as changes in the physiological curvature of the cervical spine or osteophytes, such as sudden collapse attacks and vertigo. Sympathetic cervical spondylosis: This is a kind of cervical spondylosis with complex clinical symptoms, mainly caused by stimulation of the vegetative nerves, and mostly manifests as a series of sympathetic symptoms such as dizziness, blurred vision, tinnitus, hand numbness, increased blood pressure, tachycardia and pain in the precordial area. There is also a special type of cervical spondylosis, which is mainly due to the osteophytes at the front edge of the cervical spine plus the straightening of the physiological curvature of the cervical spine or even the occurrence of retroflexion, etc., which can stimulate the back wall of the esophagus and cause symptoms such as dysphagia and dry vomiting. The clinical features of different types of cervical spondylosis are different and require a professional doctor to differentiate them from many other diseases.
