Lumbar disc herniation (LDH) is one of the most common degenerative spinal diseases in adults and less common in adolescents. The age of onset is less than 21 years old and is defined as adolescent lumbar disc herniation (ALDH). The incidence of ALDH is only 1%-5%. However, with the accelerated pace of life, the incidence of ALDH is increasing. In recent years, the rapid development of endoscopic technology has been widely used in spinal surgery. ALDH's percutaneous endoscopic technique has achieved good results. Compared with open surgery, percutaneous endoscopic treatment can preserve more normal lumbar structures, such as ligaments, muscles, lamina and facets, minimizing the impact on pubertal growth. This article reviews the characteristics of ALDH and endoscopic treatment as an entry point.
