The etiology of lumbar disc herniation can have the following ten points: (1) degenerative changes of lumbar intervertebral discs: degeneration of the nucleus pulposus is mainly manifested as a decrease in water content, causing vertebral instability; degeneration of the annulus fibrosus is mainly manifested as a decrease in the degree of toughness. (2) Trauma: observation of clinical cases shows that: trauma is an important factor in disc herniation, especially the onset of adolescents, with which it is closely related. It can cause rupture of the annulus fibrosus and avulsion of the cartilaginous endplate during mild loading and rapid rotation of the spine. (3) Occupation: the relationship between occupation and lumbar disc herniation is very close, for example: automobile and tractor drivers are in the sitting position and bumpy condition for a long time, which is easy to cause lumbar disc herniation. Engaged in heavy manual labor and weight lifting sports due to overload is also easy to cause disc herniation. (4) Genetic factors: lumbar intervertebral disc herniation can be seen in clinical cases of family group. (5) Lumbosacral congenital anomalies: lumbosacral segment deformities can increase the morbidity rate, including lumbar spine sacralization, sacral spine lumbarization, small joint deformities and asymmetry of articular eminence. (6) Sudden increase in abdominal pressure: clinically, about 1/3 of the cases before the onset of a clear increase in abdominal pressure factors, such as violent coughing, sneezing, breathlessness, defecation, etc., which can make the abdominal pressure rise and lead to a sudden increase in intravertebral disc pressure. (7) Long-term lumbar posture: Whether during sleep or in daily life and work, when the lumbar region is in a flexed position for a long time, it is easy to induce nucleus pulposus herniation. (8) Sudden weight-bearing: sudden weight-bearing can increase the load on the lumbar region, which can cause lumbar sprain and herniated nucleus pulposus. (9) Pregnancy: during pregnancy, the whole ligament system is in a state of relaxation, and the laxity of the posterior longitudinal ligament is easy to herniate the intervertebral disc. (10) Cold and dampness. Cold or dampness can cause small blood vessel contraction, muscle spasm, so that the intervertebral disc and its surrounding tissues have impaired circulation, which in turn leads to lumbar disc herniation.
