I have treated a large number of patients with lumbar disc herniation in my outpatient clinic, and I have also performed many operations for lumbar disc herniation. Many of them are young patients, including students in their teens, and some of them are young but “old” patients who have been suffering from lumbar herniation for many years. These young people visit the doctor after experiencing back pain or leg pain, and after MRI or CT examination of the lumbar spine, they are finally diagnosed with lumbar disc herniation, and some of them need surgery. At this time, patients and family members are often confused and lamented that they are young and uninvolved in the world, how come they have “lumbar herniation” all of a sudden? Many young patients are not engaged in heavy physical labor, are not professional athletes, and have not suffered any trauma, but are just ordinary workers who have been sitting for a long time, such as writers, IT workers, bank and finance workers, and many students studying on campus. How can these young patients suffer from “lumbar protrusion”? The root cause of “lumbar protrusion” is the degeneration of the fibrous ring of the lumbar intervertebral disc under the effect of various acute or chronic injuries, which weakens and decreases the strength, and the nucleus pulposus of the lumbar intervertebral disc breaks through the weak fibrous ring and protrudes into the spinal canal, compressing the spinal cord and nerves and producing various clinical symptoms such as limb pain, numbness and weakness, which is what we This is often referred to as lumbar disc herniation. If the lumbar disc nucleus pulposus is found to be protruding from the MRI or CT film of the lumbar spine, and it does not cause nerve compression and does not produce the above-mentioned neurological compression symptoms, then do not worry too much, it is only a “lumbar disc protrusion” and not a “lumbar disc herniation”. “However, it is important to pay attention to it. Since the root cause of “lumbar protrusion” is the degeneration of the lumbar intervertebral disc’s fibrous ring, many friends will question why young people’s lumbar intervertebral discs are so prone to degeneration. Why is it that many people don’t get “lumbar protrusion” from physical exercise every day, while I get “lumbar protrusion” from sitting still every day? This situation is also objective, many physical workers or athletes, so much exercise every day may not be lumbar disc protrusion, and long-term sedentary office workers, basically do not do physical exercise but often appear lumbar disc protrusion. This may have a close relationship with the work life habits of different people. Some young patients with the onset of herniated discs are engaged in long-term ambulatory work, sitting for most of their work and study time. In their spare time, this group, being younger and more fashionable, spend more time applying high-tech electronic products and networks for entertainment and study, and even often stay up late, mostly also sitting continuously without activity, basically without time for sports and exercise. The habit of sitting and not exercising for a long time in work and life may be one of the important reasons for the onset of lumbar protrusion. When a person is standing upright, the pressure on the lumbar disc is equivalent to about 1-2 times his or her body weight, and in a seated, forward leaning position such as when working at a desk, the pressure on the lumbar disc can reach about 4 times the body weight. The more you sit in office, the longer the time, the greater the local pressure load on the lumbar disc, the disc’s fibrous ring is more likely to damage degeneration. In addition, physical workers more developed back muscles, muscle flexibility and elasticity or, can share a lot of disc pressure, equivalent to the disc “decompression”, the more developed muscle, the less pressure on the disc. And long-term sedentary friends due to the lack of exercise, weight control is often poor, muscles are not developed, muscle strength is weak, elasticity is not good, the pressure should be borne by the muscles all fall on top of the intervertebral disc, equivalent to the disc “pressure”, which for a long time has to bear the overload of the intervertebral disc is like adding insult to injury. The size of the pressure on the intervertebral disc and the degeneration of the intervertebral disc fibrous ring are closely related, and it is easy to understand why many young friends who sit for a long time and do not do physical work are more prone to degeneration of the lumbar intervertebral disc fibrous ring causing “lumbar protrusion”. Through the above elaboration, I believe you have some understanding of the possible reasons why many young people are prone to “lumbar protrusion”. In fact, whether young people or middle-aged or elderly, suffering from “lumbar protrusion” is not accidental, nor is it an overnight onset, it is a slow process of chronic injury to the lumbar intervertebral disc gradually accumulating, quantitative changes to qualitative changes, careful analysis can find some reasons. After correctly understanding and clarifying the root cause of lumbar disc protrusion, we should take appropriate measures to prevent lumbar disc protrusion in our daily work life, change bad habits and develop good habits to prevent the onset of “lumbar protrusion” to the maximum. Here are some suggestions for friends, I hope it will help. First of all, it is recommended to reduce the time and frequency of sedentary and standing, preferably more bed and less late night. Because the pressure on the lumbar disc in the sitting and standing state is greater, the pressure on the lumbar disc in the bed state is minimal, and the smaller pressure can reduce the degeneration of the lumbar intervertebral disc fiber ring. It is recommended to increase lumbar back muscle strength exercises, such as five-point support, Xiaoyanfei, straight leg raise training and chest expansion exercises, etc. Outdoor activities can be increased, but it is not recommended to do strenuous sports, because strenuous exercises may damage the muscles. With stronger muscles, the pressure on the lumbar discs is less, the stability of the spine is better, and the fibrous rings are less likely to degenerate. Increased exercise also helps to control weight and reduce pressure on the discs. It is recommended to choose a soft and firm bed for sleep, avoid sofa beds and too soft mattresses, and choose a suitable mattress that will enable the patient to rest in a stable and comfortable state, so that muscle fatigue and chronic injury can be quickly recovered. I hope the above suggestions can help you to prevent “lumbar protrusion”, and also for the rehabilitation and treatment of patients who have developed lumbar disc herniation is also very helpful.
