To what extent does cervical spondylosis generally develop so that our patients need to opt for surgery? Cervical spondylosis is a herniated disc, bone spur and vertebral bone loosening compression stimulates the nerves or blood vessels in the neck, so that the nerves are directly and indirectly damaged, if not treated exactly, these causes for a long time, the nerves will successively out of inflammatory edema, ischemic metabolic disorders, demyelination changes and cell necrosis, the patients themselves can notice is the limb pain, numbness, weakness, grasping walking difficulties, and even the emergence of an arm or quadriplegia. It is like a stone pressed against a seedling, some seedlings can adapt, others cannot, and will gradually turn yellow and eventually die. Removing the stone to free the seedling is the same as surgical decompression to liberate the nerve, which requires timing and decisiveness. The timing of surgery is not quite the same for different types of cervical spondylosis. For nerve root type cervical spondylosis, first of all, it is still recommended to brake the neck brace, take sufficient rest, take oral medication and do physical therapy, but there are some cases to consider surgery. The first is that the pain and numbness in the neck, shoulder or arm are very intense, some even to the fingers, and sleeplessness at night, which seriously affects life. The pain is not relieved by analgesics, so surgery is required at this time. Especially when the MRI of cervical spine shows that the nerve compression is very serious, if not operated in time, the nerve may be necrotic. In some cases, the pain is severe at the beginning, but suddenly the pain stops one day, but there is no strength in the hands and the muscles are paralyzed. Generally nerve damage from mild to severe, patients have different symptoms, first pain sensation hypersensitivity, then heavy is numbness and weakness, then severe is no pain, is muscle paralysis and muscle atrophy. According to this analysis, so we can not wait until the muscle paralysis until it becomes very numb before doing surgery. The second situation is that cervical spondylosis is very painful and affects life, and is not relieved by one month or even two or three months of treatment and observation, and this time also requires surgery. All patients who are suitable for surgical treatment generally have good surgical results. The effect of surgery also depends on the choice of the timing of treatment. Once there are clear indications for surgery and no contraindications to surgery, it is recommended to operate as early as possible because early surgery is effective. The traditional concept of Chinese people is that it is not easy to accept or receive surgical treatment immediately. In fact, this bear and carry may not only endure the pain for nothing, but also may delay the control of the disease, affect the effect of surgery, and even have serious consequences. Unlike neurogenic cervical spondylosis, most spinal cord cervical spondylosis requires surgery and conservative treatment is ineffective. This type of patient mainly suffers from weakness and numbness of the limbs, inflexibility and clumsiness of the hands, unstable walking with the feeling of stepping on cotton, etc. It is a serious type of cervical spondylosis, and if it is not treated, most patients (60-80%) will have their condition aggravated, and the final result is paralysis. Therefore, this type of cervical spondylosis should be treated with surgery once it is diagnosed, and the lighter the condition, the earlier the surgery, the better the result. If the nerve is already necrotic, even surgery cannot save it. Sympathetic cervical spondylosis (vertebral artery type cervical spondylosis is rare, and most of the diagnosed vertebral artery type is actually sympathetic) is mainly characterized by symptoms such as dizziness and headache, panic and chest tightness, nausea and vomiting, eye pain and eye swelling and blurred vision, and unstable high and low blood pressure. Although most people advocate conservative treatment, in clinical practice we find that conservative treatment of sympathetic cervical spondylosis is often ineffective and the condition is very easy to recur. These patients have a variety of subjective symptoms and are very easy to be misdiagnosed, and most of them wander to neurology, cardiovascular medicine, gastroenterology and otorhinolaryngology, and are not properly diagnosed and treated for a long time. These patients are also prone to recurrent symptoms and require great care and stamina to treat. Patients with severe symptoms of recurrent painful abnormal episodes can be treated with conventional surgery or, in lighter cases, with minimally invasive low-temperature plasma interventions, most of which can be effective. The main goal of surgical treatment is to eliminate the intervertebral discs or bone spurs that are causing nerve compression, to re-stabilize the loosened cervical spine, and to improve blood circulation to the nerves. Regardless of whether it is the nerve root or the spinal cord that is being compressed, the ultimate goal is to remove these diseased tissue structures so that the nerve is well relieved and liberated. There are many ways to do this, either by going in from the front and cutting out the disc, or by going to the back and opening up the spinal canal. Patients with cervical spondylosis who also have diabetes or hypertension can still have normal surgery if they are controlled by medication after admission to the hospital to meet the required index. However, there are some patients who are not suitable for surgery because they may suffer from some other serious diseases or have some other problems in themselves, which are called contraindications to surgery. For example, if a patient has a serious heart problem (such as acute heart attack), or a serious emphysema, or asthma, this patient is generally unable to tolerate general anesthesia and cannot tolerate surgery. This is a major surgery for him, although we may do a single segment anterior cervical surgery in 30 minutes and 40 minutes, which is not very big, and the bleeding will not be much, that is, 10 ml to 20 ml bleeding, but for these patients, he has a serious underlying disease, we should be especially careful.
