There is soft tissue between vertebral bodies. The main significance of this soft tissue is to relieve the pressure between vertebral bodies, and the structure in the middle of this soft tissue is fibrous ring with nucleus pulposus, which is a semi-colloidal substance as soft as rubber.
In the process of patients jumping up and down, this soft nucleus pulposus will protect the lumbar spine from the impact of external forces, while the fibrous ring of elderly patients is broken, and the nucleus pulposus protrudes out of the fibrous ring, which causes the disease by compressing the nerves.

Precautions:
People who bend over or work at their desks for a long time should maintain a correct posture to relieve the pressure on the lumbar intervertebral disc, and stretch their waist regularly to relieve waist fatigue. It is suggested that you exercise 10~ 15 minutes after 60 minutes of work to relieve muscle fatigue.
Workers who have been engaged in standing work for a long time can stand on tiptoe and step on their feet alternately at work, which can make the lumbar spine protrude forward and relieve the muscle tension in the back. If you feel back discomfort after standing for a long time, you'd better stop working immediately, have a proper rest and do some waist stretching exercises at the same time. It can also be fixed on the waist with a lumbar support to reduce the pressure on the lumbar intervertebral disc.
