After summarizing the information of patients with back and leg pain caused by lumbar disc herniation treated in the past 10 years, we found that some patients were younger, mostly around 20 years old, and the patients had serious symptoms of lumbar disc herniation, and most of them had lumbar disc prolapse, with a heavy degree and huge prolapsed blocks, analyzing the reasons. 1, fibrous ring dysplasia; 2, the patient paralysis, thinking that lumbar disc protrusion will not happen in young people, when the clinical symptoms did not promptly seek medical attention; 3, a large amount of activity, the fibrous ring and intervertebral disc vulnerable to injury; 4, years of reading, no scientific exercise, lumbar back muscle strength is weak, so that the intervertebral disc fibrous ring easily damaged. The young people are reminded that if they have back and leg pain, they should seek medical attention in time. The milder degree of disc herniation can be completely solved by regular conservative or minimally invasive therapy, but if treatment is delayed, the seriousness of the lesion may only be treated by surgery.
