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 nerve is the harder fibrous ring and the epiphysis at the posterior edge of the vertebral body, not the soft nucleus pulposus, thus it is difficult to be absorbed by dehydration, so the clinical symptoms are usually obvious and should not be observed by conservative treatment, and surgery should be performed if the diagnosis is clear. Children and adolescents with lumbar disc herniation should be bedridden for a long time after surgery, recommended as 2 to 3 months, to allow scar tissue repair at the rupture of the fibrous ring at the posterior edge of the vertebral body and to strengthen the firmness of the posterior aspect of the intervertebral disc.
