Lumbar disc herniation can also occur in children and adolescents, and their causes are not quite the same as those of adults, with the presence of traumatic triggers. For lumbar disc herniation in children and adolescents, because the material compressing the nerves is the hard fibrous annulus and the epiphysis of the posterior margin of the vertebral body, rather than the floppy nucleus pulposus, and thus it is difficult to be absorbed by dehydration, so the clinical symptoms are generally obvious, and it should not be observed by conservative treatment, and it should be treated by surgery when the diagnosis is clear. Children and adolescents with lumbar disc herniation should be bedridden for a long time after surgery, which is recommended to be 2 to 3 months, so that scar tissue can be repaired at the rupture of the annulus fibrosus at the posterior margin of the vertebral body to strengthen the firmness of the disc at the posterior side of the vertebral body.
