1.What is cervical spondylosis? Cervical spondylosis is a degenerative change of the intervertebral disc tissue and its secondary degenerative (i.e. aging) changes of the intervertebral joints involving the surrounding important tissue structures (nerve roots, spinal cord, vertebral artery, sympathetic nerve, etc.), and the corresponding clinical manifestations appear. 2.What types of cervical spondylosis are there? Which diseases should be differentiated? At present, cervical spondylosis is divided into cervical type, nerve root type, spinal cord type, vertebral artery type, sympathetic type and other types (at present, it mainly refers to esophageal compression type) in the domestic orthopedic field. The cervical type is dominated by symptoms of neck pain, but other disorders of the neck must be excluded (such as drop pillow, frozen shoulder, myofasciitis, etc.); the neurogenic type is dominated by symptoms of irritation of one or several nerve roots, but extra-cervical pathologies such as thoracic outlet syndrome, tennis elbow, carpal tunnel syndrome, elbow tunnel syndrome, frozen shoulder, peripheral neuritis, etc. must be excluded; the spinal type is dominated by symptoms of spinal cord damage, but the spinal cord type must be The symptoms of spinal cord damage are mainly the spinal cord type, but progressive amyotrophic lateral sclerosis and intravertebral tumor must be excluded; the symptoms of irritation or compression of vertebral artery are mainly the vertebral artery type, but ophthalmogenic or otogenic vertigo, insufficiency of blood supply to the first or third segment of the vertebral artery and intracranial tumor must be excluded; the symptoms of sympathetic nerve irritation are mainly the sympathetic type, but other systemic functionalities such as neurosis and organic tumor must be excluded. The symptoms of sympathetic nerve irritation are sympathetic type, but other system functionalities such as neurosis and organic diseases must be excluded. 3.Is cervical spine osteophytes cervical spondylosis? Cervical spine osteophytes are a manifestation of degenerative changes in the cervical spine, which are manifested on X-ray as an increase in the density of local bone and the appearance of new bone at the edge of the bone (i.e. bone superfluity, commonly known as bone spurs), and are often accompanied by instability of the cervical spine. Degenerative changes in the cervical spine are a manifestation of the human life cycle, an aspect of the human body moving from maturity to decline, and a physiological degenerative change in the cervical spine in order to adapt to long-term movement and load. This degeneration occurs gradually as a person develops, grows, matures, and ages at the same time. From the age of 30, the cervical spine will gradually undergo degenerative changes. The development of this degenerative change is gradually accelerated along with age. Cervical spine osteophytes cannot be diagnosed as cervical spondylosis if they do not cause irritation or compression of the nerve roots, spinal cord, sympathetic nerve or vertebral artery and do not produce any corresponding symptoms. However, once the cervical spine osteophytes narrow the spinal canal, intervertebral foramen, transverse foramen, etc., or cause instability due to degenerative changes in the cervical spine, so that the nerve roots, spinal cord, sympathetic nerve or vertebral artery are compressed or stimulated, and the corresponding symptoms appear, it is not a simple cervical spine osteophyte, but cervical spondylosis. 4.What are the ways of cervical spondylosis surgery? Is it dangerous? The main surgical methods for cervical spondylosis are anterior cervical disc removal and or vertebral body subtotal dissection and internal fixation, posterior laminoplasty, and combined anterior and posterior surgery. The unique anatomical structure of the cervical spine, the presence of important nerves, spinal cord and blood vessels around the cervical spine, and the presence of peripheral structures such as the thyroid gland, trachea and esophagus determine the complexity and danger of cervical spine surgery. In fact, there is a certain degree of danger in any surgery, ranging from large operations on the heart, cranium and cervical spine to small ones such as tooth extraction, corns and powder tumor removal. The success or failure of surgery depends on many factors. These factors include the preparation before surgery, the cooperation of doctors, nurses and patients during surgery, and the treatment and care after surgery. The chance of complications varies from hospital to hospital due to differences in proficiency, skill and experience in different surgeries. Therefore, it is reasonable for patients to say that “my surgery must be done in a trustworthy hospital”. With the continuous improvement and enhancement of surgical methods and techniques, the popularization of medical knowledge among the general public, and the increasing modernization of medical devices and equipment, the safety of cervical spine surgery will be further improved. Patients are recommended to go to “triple A” hospitals for cervical spine surgery. 5.How much does cervical spine surgery cost? Is the hospitalization period long? Generally speaking, anterior cervical spine surgery is about 25,000 yuan (with domestic instruments), while posterior spine surgery is about 12-15,000 yuan. The general hospital stay for anterior cervical spine surgery is about 7-10 days, while posterior surgery is about 12 weeks, with a rest period of 3 months after surgery, but it often takes about 1 year to recover in severe cases. 6.Surgical results and success rate? As long as the diagnosis is clear and the indications for surgery are strict, the surgical results are relatively good. The overall excellent rate of surgical patients is more than 85%, and the recurrence rate does not exceed 5%. There are several cases in which the treatment result may be poor: a. Significant atrophy of the intrinsic muscles of the hand b. Extensive degeneration of the spinal cord over a long period of time c. Combined neurological diseases d. Advanced age patients.
