Parents of children often ask me this question: Doctor, our child is so small, how could he get lumbar disc herniation? In fact, we encountered in the clinical situation of small children with lumbar disc herniation is not an isolated case, but a relatively common phenomenon, I summarized my previous 100 cases of minimally invasive intervertebral foramenoscopy treatment of lumbar disc herniation, and found that there were 3 cases of patients aged 10-20 years old, which accounted for 3% of the total, and there were 24 cases of patients aged 20-30 years old, which accounted for 24% of the total. The two age groups together have accounted for 1/4, which is enough to see that the proportion of teenagers getting lumbar disc herniation is not low. There is a Korean study investigated 39,673 19-year-old male youth, found that the incidence of lumbar disc herniation is 0.6%, while the incidence of severe lumbar disc herniation is 0.28%. In fact, this category of disease is called adolescent lumbar disc herniation, which has its own characteristics relative to adult lumbar disc herniation. First of all, many children with lumbar disc herniation have certain abnormalities in the structure of the lumbar spine, which has a certain influence on the occurrence of lumbar disc herniation, for example, some scholars believe that congenital lumbar 5 vertebral sacralization is an influential factor in lumbar 4-5 intervertebral disc herniation. Secondly, traumatic factors also have an important influence in adolescent lumbar disc herniation, small children like strenuous exercise, and inappropriate strenuous exercise or trauma caused by exercise often brings hidden danger. The third is sedentary and other bad habits, nowadays children have a heavy burden of study, often sedentary listening to lectures, doing homework, which brings a lot of pressure on the lumbar spine. The fourth is genetic factors, many scholars have studied the genes of children with lumbar disc herniation and found that some genetic abnormalities are related to adolescent lumbar disc herniation. Therefore, parents are reminded that if children often reflect back pain leg pain leg numbness, coughing, sneezing, bowel pressure or exercise after back pain or leg pain obvious, may have lumbar disc herniation, need to go to the hospital earlier for treatment.
