Lumbar disc herniation is mainly caused by lumbar degeneration, injury factors, and lumbosacral congenital abnormalities. 1. Lumbar degeneration: the intervertebral disc tissue is a connecting structure that contains an elastic gelatinous substance with high water content, which has the effect of cushioning spinal pressure and shock. With age, the discs may degenerate or even protrude, which can lead to low back pain. 2. Injuries: including chronic injuries and acute injuries, chronic injuries include sports injuries, prolonged sitting and squatting, physical labor, etc., all of which may lead to lumbar disc herniation. 3. Lumbosacral congenital abnormalities: lumbarization of the sacral vertebrae, small joint deformities, sacralization of the lumbar vertebrae, and asymmetry of the articular eminence, all of which may lead to changes in the stresses on the lumbar vertebrae, resulting in lumbar disc herniation. Lumbar disc herniation may be related to age factors, gender factors, occupational factors, once in the emergence of the need to consult a doctor in time to clarify the cause, active treatment.
