In recent years, the incidence of lumbar disc herniation in adolescents has gradually increased. The parents of the children are so anxious to seek medical treatment. The reason for this is that it is related to the incorrect sitting, standing and sleeping postures of adolescents. Nuclear magnetic or CT shows that such patients are mainly lumbar disc bulging, nuclear magnetic shows that the dural sac is more heavily compressed, the image of the annulus fibrosus is intact, and there is no obvious free protrusion. Lumbar spine surgical openings revealed that the discs of adolescent lumbar disc herniation patients were more tense, and after incision of the annulus fibrosus, the resected nucleus pulposus tissue was relatively small and sticky. Therefore, the means of treatment is based on resolving the tension within the intervertebral disc, and minimally invasive means can be a good solution to this problem. In terms of prevention and health care, first of all, adolescents should develop a correct sitting posture and keep their upper body straight in their daily school life. Don’t lean your body weight too much on the back of the chair. Avoid crossing your legs for a long time when standing. Standing should also keep the upper body straight, avoid hunching back, slightly tighten the abdomen, lift the buttocks. Secondly, develop a regular routine. During the daytime most of the time due to the upper body in an upright state, lumbar intervertebral discs due to the weight of the body is in a state of compression. At night, when you sleep in a flat position, the lumbar intervertebral discs are fully relaxed, and the endplates of the intervertebral discs will automatically absorb nutrients to replenish the intervertebral discs. Favorable to the development of lumbar intervertebral disc and health care. In addition, should avoid prolonged sitting and standing study, should get up and move every 45 minutes. Avoid playing computer games for a long time, which is unfavorable to both cervical and lumbar vertebrae. In short, teenagers should develop a good living, sitting and standing posture, so as to better protect the intervertebral discs.
