Scholars at home and abroad generally believe that surgery for spinal cord cervical spondylosis has the best efficacy within six months of onset, and the longer the disease duration, the worse the efficacy; surgery for spinal cord cervical spondylosis should be performed within two years of onset to achieve better surgical results. For other types of cervical spondylosis (nerve root type, sympathetic nerve type and cervical discogenic pain), if conservative treatment is ineffective and it is determined that surgery should be performed, early surgery should also be pursued in order to obtain better surgical results. The anatomy of the neck is complex, and surgery for cervical spondylosis operates on the surface of the most important nerves, which is relatively risky, and surgical complications cannot be completely avoided, so surgical treatment of cervical spondylosis has not yet become popular in primary care hospitals. However, for experienced surgeons, good surgical treatment results can be obtained for the majority of patients with few complications. Nowadays, the technology of surgical treatment for cervical spondylosis has been perfected, so the majority of patients who need surgical treatment do not need to worry too much about it, and can receive surgery in a large hospital with rich surgical experience in a safe and happy manner. According to the statistical analysis of long-term observation 8-20 years after anterior cervical spine surgery and 10-13 years after posterior cervical spine surgery, the excellent rate of surgical treatment for each type of cervical spondylosis is about 90% for the neurogenic type, 80% for the spinal type and 77% for the sympathetic type. For neurogenic cervical spondylosis, most of the surgical results are immediate, and a few patients who have been operated too late have poor recovery, and the recovery of muscle atrophy and hand numbness and weakness is not obvious. Sympathetic cervical spondylosis surgery has an excellent rate of 77~84%, the symptoms of this type of patients are more difficult to control, the recovery time is often long after surgery, there are often recurrent and fluctuating symptoms, and some are partial improvement of symptoms, but overall the surgery will still benefit most patients, significantly reducing pain and improving the quality of life. For patients with spinal cord cervical spondylosis, if spinal cord nerve degeneration, heavy cervical spinal stenosis, and heavy spinal cord compression and deformation are found on MRI, the effect of surgery is less effective; if cervical spondylosis is complicated by trauma resulting in sudden aggravation of spinal cord injury leading to tetraplegia, the postoperative effect is generally much worse. In addition, there is a recurrent process of recovery of symptoms after surgery for patients with spinal cord cervical spondylosis. Generally, during surgery or within a few days after surgery, patients feel relaxed and strong in their limbs, and their symptoms are obviously relieved. After 4 or 5 days of surgery, some patients’ neurological symptoms may be aggravated again, which is often a sign of secondary edema after spinal cord decompression and usually lasts for several weeks. After this, the symptoms can gradually improve again, and after 3-6 months, the speed of improvement of the symptoms will gradually slow down again, and about two years after the surgery, the symptoms usually no longer improve and become stable. Some patients feel relief of symptoms immediately after surgery; the majority of patients need a longer recovery time, usually 1~2 years, some longer. Therefore, those who are not satisfied with the functional recovery in the short term after surgery should not be anxious and should wait until one year to see the results. Some patients with spinal cord cervical spondylosis require decompression surgery for both the anterior and posterior cervical spine. Due to the presence of multiple pathological factors after degeneration, such as developmental cervical spinal stenosis, bone spurs at the posterior edge of the vertebral body, disc herniation and ossification of the posterior longitudinal ligament, which compress the spinal cord from the front, and factors such as hypertrophy of the ligamentum flavum, which compress the spinal cord from the back, some patients with complex conditions can be solved by posterior cervical spine surgery alone, but some patients need to undergo posterior cervical spine surgery and anterior cervical spine surgery successively. However, some patients need to undergo posterior cervical spine surgery and anterior cervical spine surgery, usually starting with decompression in the direction of heavier compression. For example, the anterior or posterior cervical spine surgery is performed first, and after a period of observation, if the symptoms do not resolve significantly or remain, the posterior or anterior cervical spine surgery can be performed again. Some patients with cervical spondylosis are discharged from the hospital after successful surgery, but many years after surgery, as the cervical spine continues its degenerative process, or as cervical spine degenerative strain is accelerated due to neck trauma and improper use of cervical spine maintenance, new hyperplastic bone spurs and cervical spine instability can appear in the cervical spine, which can cause new compression on the spinal cord and nerve roots again. As a result, some patients may experience a recurrence of symptoms years or 20 years after surgery, and some patients may have to undergo a new surgery. Of course, the results of this surgery are less effective than the first surgery. There are also very few patients whose symptoms are relieved for a period of time after surgery, but after six months or a year the symptoms come back and worsen, and the MRI is repeated to see that the spinal cord has been completely decompressed and there is no compression at all, so this situation is analyzed mainly because the spinal cord nerve blood flow disorder or spinal cord degeneration is aggravated, so we advocate – if cervical spondylosis requires surgery, the sooner it is done, the better.
