There is no doubt that teenagers can also get a herniated lumbar disc. Often some elderly people will say to their children: where is the child’s waist, how can they have a lumbar disc herniation? In fact, this view is not correct. Nowadays, the prevalence of lumbar disc herniation among adolescents is still very high, and the youngest patient I ever operated on was only 12 years old! So what are the causes of lumbar disc herniation in teenagers? The following I summarized a few points: 1, sitting for too long, too little exercise. Due to the pressure of children’s studies, sedentary ambulation, which is easy to cause lumbar muscle strain, but also adverse to the absorption of calcium, affecting the development of bones. 2, strenuous exercise. External forces acting on the lower back, when more than a certain limit will occur when the disc protrusion. 3, poor development. With the improvement of living standards, children’s adolescence advance, girls at the age of 11-14, boys at the age of 12-15 years of age in the three years of rapid growth, rapid ossification of cartilage plate, incomplete development of the intervertebral disc, high water content of the nucleus pulposus, while the collagen content is less, the disc is not flexible enough, the strength of the lumbar muscles is also obviously insufficient, in the sudden external force is prone to disc protrusion. The lumbar intervertebral disc is one of the earliest organs in the human body to metamorphose and age, and it is like the lens of the eye, which has a high water content. The water in the lumbar intervertebral disc starts to dehydrate at the age of 15, so if you don’t pay attention to it, the lumbar intervertebral disc elasticity decreases coupled with strain, it will easily cause the disc to protrude, so teenagers should also pay attention to the health care of the lumbar spine.
