Lumbar disc herniation is a syndrome that occurs when the spinal cord or nerves are compressed by the rupture of a degenerated disc, and is a common and frequent disease of the spine, mostly seen in middle-aged and elderly people and long-term manual workers. However, recent studies have shown that a small number of adolescents also suffer from lumbar disc herniation, and the incidence is on the rise, which significantly affects adolescent growth and development and physical and mental health. Almost all adolescent patients and their parents who come to me ask, “Why do I have a herniated lumbar disc at such a young age?” Current research shows that the occurrence of lumbar disc herniation in adolescents may be related to the following reasons: 1. congenital developmental defects of the lumbar intervertebral disc, such as congenital uneven development of the cartilage end plate, or even concavity of the end plate. The cartilage end plate is an important structure in the process of nutrient metabolism of the intervertebral disc, and once defects occur, then the rate of lumbar disc degeneration will increase significantly, so that disc herniation will easily occur. 2, among the patients seen, some are overweight teenagers, which is also related to their occurrence of lumbar disc protrusion, because excessive weight obesity will increase the load on the disc, thus accelerating the degeneration of the disc, resulting in premature disc lesions. 3, trauma leads to intervertebral disc, cartilage end plate breakage. The adolescents are active and playful by nature, and they are not good at self-protection, often involved in strenuous sports, sometimes when a strong external force (high jump, strong twisting, etc.) on the lumbar area, may increase the tension in the intervertebral disc, when more than a certain limit may occur when the disc protrusion. Sometimes, the external force directly causes the cartilage endplates of the disc to rupture, thereby compromising the stability of the entire disc, which can eventually lead to a herniated disc. If a child is suspected of having a herniated disc, parents should take them to the doctor in a timely manner so that treatment is not delayed. So as a parent, how should you observe if your child has a herniated disc in adolescents? Adolescent disc herniation is usually characterized by the following clinical features: lumbar pain and radiating pain and numbness in both lower extremities, significant stiffness in the lumbar region, and a skewed spine. If your child has any of these symptoms, he or she should be brought to the hospital for examination and, if necessary, CT and MRI examinations to assess the condition of the lumbar spine. What is the proper treatment for an adolescent disc herniation when it is diagnosed? The treatment should be combined with the patient’s symptoms, signs and relevant imaging examinations. For those who have a clear history of recent lumbar trauma, lumbar symptoms such as low back pain, spinal stiffness and scoliosis, but no lower extremity symptoms, and no obvious disc protrusion on CT examination, or the protrusion is not significant, they can be given the treatment. Or the protrusion is not large, conservative treatment can be given. The main methods are: bed rest for 2-3 weeks, orthopedic manipulation, lumbar back muscle exercise, drugs, acupuncture, traction, physical therapy, lumbar girth protection for 2-3 months, etc. Most patients can be relieved. However, for patients with obvious symptoms, nerve compression symptoms, or even nerve damage, they should be actively treated with surgery. Depending on the stability of the lumbar spine, the development of the lumbar spinal canal and the nature of the nerve compression, two types of surgery are available: minimally invasive open decompression nucleus pulposus removal surgery, and expanded decompression and fusion fixation surgery.
