Adolescent-type lumbar disc herniation is less common. The incidence rate is 0.8-3.8% in Western countries, and is significantly higher in Japanese than in Caucasians, ranging from 7.8-22.9%. There is a history of significant trauma and symptoms of low back pain begin immediately after the trauma. Repeated trauma is considered to be an important cause of lumbar disc herniation in this age group. The incidence is more common in men and is related to activity and exercise level. The clinical presentation and response to treatment differs from that of adults. Adolescent lumbar disc herniation is characterized by the following features: patients tend to be taller than their peers; there is a history of significant trauma, with low back and leg pain occurring immediately after the injury; and patients have few symptoms but many objective signs. Therefore, in terms of diagnosis, physical signs and imaging changes are more reliable than symptoms. Some had both obvious symptoms and obvious physical signs. Therefore all patients had obvious physical signs during physical examination. The main manifestations are lumbar scoliosis, physiological anterior convexity reduced, disappeared or even posterior convexity, movement limitation, sacrospinal muscle spasm, and positive straight leg raising test, which is mostly limited to the range of 30o or less. Due to the greater spinal mobility in adolescents, the nerve roots can avoid severe compression, and the patient’s sensory and tendon reflex changes in both lower limbs are often not obvious. Neurological examination, such as sensory distribution area disorder, lumbar reflex changes are less. CT scan and MRI examination can confirm the location, size and degree of compression of the protrusion of the nerve root and dura mater; more than half of the patients are accompanied by other spinal disorders conservative treatment is often ineffective, and early surgery is effective. Children and adolescents type lumbar disc herniation, mostly due to the disc cartilage end plate backward stick position. The herniated disc can be removed by hemilaminectomy or total laminectomy or percutaneous nucleotomy. The postoperative symptomatic relief rate is 85%, and the excellent rate is 82%.
