The lumbar intervertebral disc should be more or less heard of, but it is a “good employee” in our body. It not only plays a role in connecting the vertebrae, bearing the role of gravity, but also plays an irreplaceable role in maintaining the posture, bending, weight bearing and activities of our body. But how did you “offend” such a lovely “employee”? From the common triggering factors of lumbar disc herniation, we usually divide these triggering factors into two categories: 1, chronic accumulation of some strain injury (the most common), age 30-45 years old, these people are often related to occupation, such as textile factory workers, drivers, IT workers, sculptors, students, etc., the reason for this, often and its long time low head, desk has a lot to do with, and like before due to labor Weight-bearing, long-term bending workers (machine processing plant, workshop) are also found in the middle-aged and elderly, often over 50 years old, heavy labor is the nature of their work when they were young. 2, external impact (car accidents, sprains, falls, etc.), relatively rare, often seen mostly in young people (20-30 years old). And it is a simple disc herniation with typical symptoms. As for other factors, such as pregnancy, obesity, smoking, abnormal spinal structure and heredity are also factors in the development of lumbar disc herniation, but they are relatively rare in daily life. I have been engaged in neck, shoulder, lumbar and leg pain for many years, and talk about several more special pathogenic factors of clinical lumbar disc herniation patients from my own work. 1, the end of the basin to wash the foot water, but the intervertebral disc disease sufferers. The old Zhang more than 60 years old, although the old problem of back pain, but never how severe pain, often by rest and rest, plaster, physical therapy a few can pass. However, last night, after washing his feet and carrying a basin of footwash water, he had severe back pain and left lower limb pain. I couldn’t stand it, so I was hospitalized: MRI of the lumbar spine showed “huge left posterior protrusion of the L4/5 disc”! 2, a cough does not matter, back pain and leg pain can not move. In the cold winter, cold is more common. Once the cold, cough, sore throat, general discomfort is very painful. Old Sun is more deeply felt. Last winter, he had a cough and sore throat after catching a cold. One morning, his throat was still uncomfortable, so he coughed hard, and to his surprise, he had back pain and leg pain symptoms. To our hospital a check, “lumbar disc herniation”. It seems that age has reached, cough also need to be careful! 3, long-distance freight drivers dry, inadvertent but put the intervertebral disc protrusion. Xiao Wang for a company long-distance freight driver, a drive is a few days and nights, although the middle can rest, but a long-distance freight task down, or very hard. This is not, another few days and nights of arduous road trip, just delivered the goods, just to get off when a get up, their waist but suddenly pain, and the emergence of the left lower limb radiating pain. I had no choice but to come to the hospital, combined with the signs and images diagnosed as “lumbar disc herniation”. 4, the grandson is really cute, for hugging you but the body harm. The grandson was raised in his own home. As their daughters and sons-in-law are busy, the grandson’s food, drink and care by themselves, they are busy and tired, it does not matter, as long as their children live well. Gradually his grandson has been 5 years old, see the grandson cute healthy and strong growth, they are also very happy. However, one afternoon, when I was picking up my grandson from kindergarten, I had a hard time holding him, and I couldn’t straighten my back, and it was very painful. The right lower extremity had pain from the waist and hip, the back of the thigh and the outside of the calf, and it was difficult to walk. In this way, he came to our hospital and was diagnosed with “lumbar disc herniation”. 5, the development of software is really busy, who knows but the lumbar disease committed. Xiao Zhang for a large software company work important software developers. People long spirit, work is young and promising, has been the envy of others “high, big, up”. But Zhang’s work is also really busy. As soon as the work began, a day sat on the past. As the company developed the software task is due, so overtime is not a problem. But it was after his intense work, leisure time to drink a glass of water, suddenly back pain, sitting and lying down can not, they came to our hospital, the image shows “L4/5 disc herniation”. 6, squatting to repair the motorcycle, take the pliers to the disease. Xiao Li is a pastry business in the village, and he rides a motorcycle to and fro when he has nothing to do. There is a period of time their own store business is busy, consecutive deliveries and pick-ups for a number of days, have to, the motorcycle was riding bad. He found tools to repair it on the ground. When he turned around to get the pliers behind him, he suddenly developed back pain and could not move. I had no choice but to come to the hospital, lumbar spine MRI: “L4/5 disc herniation”. 7, toilet force to pull the stool, which know two stool are difficult. The old Huo’s lumbar disc herniation is an old problem, which is committed every year, and it gets better with conservative treatment every year. Usually do not take the disease seriously. However, this year, the back pain is more powerful than ever, so these days they plan to go to the hospital for proper treatment. In the evening when I was planning to go to the hospital tomorrow, I went to the toilet and when I strained to defecate, I had unbearable back pain, numbness around the anus and both lower limbs, and difficulty in defecating. After arriving at the hospital, an enema and urinary catheterization were performed. After rechecking the MRI of the lumbar spine, I realized that the previously herniated disc had prolapsed and had fallen into the spinal canal, causing compression of the cauda equina nerve and resulting in dysfunction of the second stool. 8. Summary and analysis: Low back pain (LBP) is a relatively common phenomenon in daily life, and in an American epidemiological study, it was shown that LBP is the second most common clinical condition after upper respiratory tract disorders. People constantly flex their lumbar spine and rarely extend it in their daily activities, and spend a lot of time in flexion every day. Statistics show that the frequency of lumbar flexion can be as high as 3,000 to 5,000 times/d. Week after week, the progression of low back pain is inevitable. Due to its repeated attacks, 1/3 of them are transformed into lumbar disc herniation disease. So we have to pay attention to it in our daily life. Why does the above action lead to the offending disease? What should we pay attention to in our daily life? Among the various structures that make up the spine, the one that is subject to great stress and moment is the intervertebral disc, which forms a triple joint complex with the two small joints behind it. The arms and trunk form a long anterior lever when lifting heavy objects, and a shorter posterior lever from the spinous process to the nucleus pulposus (pivot point). The ratio of the front to rear lever is 15:1. If lifting 50kg, the muscle contraction of the rear lever requires 750kg, while the pressure on the nucleus pulposus is 800kg. When the human body stands, the axial pressure on the intervertebral disc is 80%-90%, and the pressure on the rear two small joints is 10%-20%. Moreover, the pressure on the disc is three times the weight of the body above its plane. During various activities, the pressure exerted is even greater, twice as much as it is at rest. The nucleus pulposus is a relatively water-rich “jelly-like” substance. While it is subjected to the pressure of the vertebral body, it can transform the force into the tension of the surrounding annulus fibrosus, which is 3-5 times the pressure of the nucleus pulposus. Especially the human body in bending and rotating this posture, our intervertebral disc to withstand the torsional force and shear force is greater, so also more dangerous. As the human body is subjected to short periods of high energy forces (such as weight lifting) or long periods of low energy forces (forces beyond normal physiological activities, such as exertion), forcing the nucleus pulposus to reduce the collagen collagen component of the annulus fibrosus, if a certain force repeatedly acts on the disc beyond a certain point that the disc is subjected to, the disc will tear, eventually leading to disc herniation, compression and stimulation of the spinal and cauda equina nerves, resulting in low back pain. This results in low back pain. The common causes are just the “last straw” that broke the camel’s back. For the preventive measures of lumbar disc herniation, we should do the following: 1, have a correct understanding of the disease, eliminate worries, cooperate with doctors to do prevention and treatment work to prevent the disease from progressing; 2, moderate work and rest, avoid a body position (such as sedentary) under the persistent work; 3, try to maintain the correct posture in working life; 4, enhance physical fitness, improve muscle endurance, strengthen the core muscle group of labor intensity; 5, eliminate 5.eliminate all kinds of unfavorable stimuli to the lumbar region: cold, humidity, cold, constipation, obesity, alcoholism, poor lying position, etc.; 6.strengthen labor protection, avoid frequent bending and weight-bearing and sedentary factors that are easy to suffer in the work, pay attention to interval exercises and rest between work, and adjust the working condition; 7.treat acute lumbago in time to avoid turning into chronic. Chronic low back pain regularly seek specialist consultation and plan treatment to achieve the purpose of prevention and treatment.
