The basic factor of lumbar disc herniation is the degenerative changes of the intervertebral disc, and the factors inducing lumbar disc herniation are roughly divided into the following categories: 1, trauma Acute injuries, such as lumbar sprain, do not directly cause lumbar disc herniation. But in the case of losing the protection of lumbar back muscles, it is very easy to cause disc herniation. 2, excessive weight bearing Engaged in heavy manual labor and weight lifting sports often due to excessive load caused by early degeneration of the intervertebral disc. When the spine is loaded with 100kg, the normal intervertebral disc space narrows to 1.0mm, and expands to the side by 0.5mm. When the intervertebral disc degenerates, the same weight is loaded, and the intervertebral disc space narrows to 1.5-2mm, and expands to the side by 1mm. 3, long-term vibration of the automobile and tractor drivers in the work, and in the long term in the seated and upside down state, the lumbar discs are subjected to a greater pressure. It has been determined that when the driver stepped on the clutch, its intervertebral disc pressure doubled. So long-term repeated disc pressure increase, can accelerate the degeneration or herniation of the intervertebral disc. 4, the impact of poor posture people in the completion of a variety of work, the need to constantly change a variety of positions, including sitting, standing, lying and difficult to avoid a variety of non-physiological posture, bad posture often induced the occurrence of this disease. 5, spinal deformity congenital and secondary spinal deformity patients, the pressure on different parts of the annulus fibrosus is not the same, and there is often twisted, easy to accelerate the degeneration of the intervertebral disc.
