-How to understand the occurrence, development, recurrence and postoperative recurrence of lumbar disc herniation Lumbar disc herniation is a degenerative disease of the lumbar intervertebral disc due to various causes. In such a natural process of occurrence, development, maturation, aging, and death of human beings, degeneration is an all too natural process. The degenerative process itself can be asymptomatic, but if the degenerative disc is displaced or inflammatory, and the nerves are compressed or irritated, the body will experience the unpleasant sensation of pain. Out of human instinct, in order to eliminate the annoyance caused by pain, people seek medical help in different ways and use different treatments to achieve pain relief, relieve pain and enhance their quality of life in society or in the family. Degenerative changes in humans are a long life process. During this process, patients develop symptoms to different degrees, depending on their physical condition. The vast majority of patients can achieve clinical remission or long-term remission with rest and conservative treatment. Some patients may experience recurrence of symptoms and prolongation of symptoms, but there is no need to panic about this, as these are normal manifestations of degenerative diseases. There is an essential difference between lumbar disc herniation and tumor, it is not a fatal disease, it is a chronic disease, and the recurrence of symptoms is a normal process of degenerative disease. For those patients with lumbar disc herniation who do not see any effect through conservative treatment, they need to be treated through surgery, and people are like a car, there are always problems of one kind or another during the effective use period, which need to be repaired in time, otherwise, it will lead to bigger problems. However, the repaired car can not be compared with the original car in any case, it is more or less to have the traces of repair, it is not realistic to have it perfect. Doctors are similar to car mechanics in that they can maintain and repair damaged organs in the human body, but they cannot change the nature of the finite nature of the body’s life cycle. The same is true for the human organ, the intervertebral disc. A doctor can repair it and try to stop irritating and compressing the nerves, but he cannot make the disc a functioning disc. After a car is repaired, if it continues to be used, the car is unlikely to last forever, and any failure can occur. It is not uncommon for symptoms to reoccur and for the disc to require treatment as the person has to return to normal life and work immediately after treatment. The minimally invasive theory of treatment is based on the concept of ladder therapy and the concept of small and modest operations, which provides a good basis for re-treatment. With the emergence and application of new technologies, many severe disc herniations can be treated with minimally invasive endoscopy. Even with conventional internal fixation, many of the symptoms that reappear after treatment can be remedied by applying endoscopic methods. Malignant diseases such as tumors, such as lung cancer, stomach cancer, and liver cancer, once recurrence and metastasis occur, are equivalent to declaring an end-of-life period. The nature of post-operative recurrence of lumbar disc herniation is different from that of tumor recurrence. It does not metastasize and is not fatal, but at most it is just pain and functional limitation of different degrees. And this recurrence rate is very low, the recurrence rate of open surgery is 14-21%. The authoritative expert endoscopic surgery 2%. Simply put, the rate of endoscopic return after open surgery is twice as high as the rate of return after endoscopic surgery. This shows that any surgery has a return rate. This means that all have the possibility of recurrence, and we need to understand and view this problem correctly. In conclusion, in clinical work, after conservative treatment of lumbar disc herniation, recurrence is a normal process of degenerative changes in people. Recurrence of lumbar disc herniation after surgery is and is a common process of change. The endoscopic surgery for lumbar disc herniation does not destroy the bone structure and ligament structure of the spine, and the return rate of recurrence occurring after surgery is no higher than that of open surgery. The times are progressing, science is developing, and with more in-depth research and study of this discipline of medicine, doctors will provide treatment techniques that will be less risky, less traumatic, and faster in recovery than traditional techniques.
