First, what is lumbar disc herniation lumbar disc herniation mainly refers to the lower lumbar spine, especially lumbar 4 ~ 5, lumbar 5 sacral 1, and lumbar 3 ~ 4, the disc of the annulus fibrosus rupture and nucleus pulposus tissue protruding, compression and stimulation of the corresponding level of one or both sides of the sciatic nerve root caused by a series of symptoms and signs Second, what kind of reasons easy to lead to the herniation of the lumbar disc herniation of a lot of triggering factors. Among them, lumbar intervertebral disc degeneration is the root cause. Physiological degeneration of the intervertebral disc begins at the age of 20, and at the age of 30, degeneration is already obvious. Degeneration of the annulus fibrosus shows thickening of the collagen fibers and the appearance of small cracks, cracks gradually widen with the degeneration process, if under the repeated action of pressure, flexion and rotational stress, it can cause the annulus fibrosus to tear and nucleus pulposus protrusion occurs. Third, what is the high incidence of lumbar disc herniation crowd Long-term stooping workers, especially sitting. Such as ambulatory workers. The nucleus pulposus is squeezed to the back side for a long time. The posterior part of the annulus fibrosus is subjected to greater tension stress for a long time. In addition to the lumbar intervertebral discs behind the fibrous ring is weak, easy to herniate, observation shows. 52.1% of the lumbar intervertebral disc herniation patients are light manual laborers: such as leaders, teachers, clerical staff. Rehabilitation Center of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine Ge Yabo repeatedly lifting heavy objects, vertical vibration, torsion occupations. Such as: porters, drivers Smokers: the incidence of low back pain in smokers is significantly higher than in non-smokers. Because smokers increase respiratory diseases, coughing makes the abdominal muscles and abdominal and dorsal muscles strong contraction, intra-abdominal pressure increases thus increasing the internal pressure of the intervertebral discs, in addition, nicotine can make the vertebral blood supply decreased, resulting in a decrease in the solute through the diffusion to the intervertebral discs, affecting their normal metabolism. Smokers arterial blood oxygen partial pressure is reduced, the intervertebral disc lactic acid production increases, accelerating the disintegration of the intervertebral disc matrix. Psychological factors: long-term boredom, anxiety or nervousness about the career of the occupation. Fear of psychological people, the rate of lumbar disc herniation is high Fourth, what are the manifestations of lumbar disc herniation 1, lumbar: lumbar disc herniation patients more lumbar pain, affecting the lumbar back and the affected side of the buttocks, and in severe cases, accompanied by sciatica. Lumbar pain is the earliest symptom. 2.Sciatica: it is caused by the nerve irritation radiating to the lower limbs on the affected side. This kind of pain is mostly manifested in the back of the femur, the lateral side of the calf, the lateral side of the heel and dorsum of the foot and the bunion [toe]. 3.Numbness: the nerve root is continuously compressed. Numbness and muscle contraction can occur at the same time. 4.Cold lower limbs: a few patients with lumbar disc herniation feel that their lower limbs are cold, sweatless or have lower limb edema. 5, intermittent claudication 6, cauda equina symptoms: pubic numbness, tingling defecation and urination difficulties. Bilateral sciatica 7. Muscle paralysis, atrophy V. Tips for disc disease patients Correct body movement mechanics to avoid lumbar sprains Mo bend over! Stay close to your body when lifting objects, use your legs to lift objects not higher than your chest, use foot cushions if necessary, get help when lifting heavy objects, and pay attention to smooth steps to avoid imbalance of the center in the middle of the process. Do not bend or twist your body when lifting heavy objects with your legs upright, and avoid lifting objects over your shoulders; these positions may cause injuries. Stand for long periods of time with one foot elevated, and from time to time stand on your feet. Stand straight and maintain a normal curvature of the spine. Good walking posture is head up, palate down, toes pointing straight ahead, and wear comfortable shoes with a good heel. Don’t stand in the same position for too long, don’t bend over when your legs are upright or walk in a bad position, and don’t wear high heels or flat shoes to stand or walk for too long. The height of the chair is moderate, in order to keep the knees and hips at the same height, close to the back of the chair to sit steadily, and both feet can be flat on the ground as appropriate. Don’t sit in a chair that is too high or too far away from your work point to prevent your upper body from leaning forward or your back from arching and becoming paralyzed in the chair. Never sit too far back to drive, extend your feet on the pedals to straighten your arms to drive and reduce the curvature of the lower back and spine. Don’t lie on a soft, center-sunken, unsupportive mattress, especially prone to concave backs or back sprains when sleeping prone.
