Patient: description of the condition (onset time, main symptoms, hospitalization, etc.): conservative treatment massage do not understand the cause of the disease, O (∩_∩)O thank you! Xinjiang Autonomous Region Hospital of Traditional Chinese Medicine massage Zhang Yi: Hello, first of all, we need to understand the structure of the intervertebral disc. The intervertebral disc is a flat cystic tissue composed of the annulus fibrosus and the nucleus pulposus, and its structure is more like the kind of children play with a pinch on the flat and elastic water balloon. The annulus fibrosus is the gelatinous elastic material on the outside, while the nucleus pulposus is made up of more than 95% water, somewhat similar to jelly. The role of the disc is equivalent to that of a spring, which acts as a shock absorber and pressure insulator between the two vertebrae. Springs have a lifespan, and so do intervertebral discs. Xinjiang Uygur Autonomous Region Hospital of Traditional Chinese Medicine massage Zhang Yi in the pressure is too large, long time load, trauma and other circumstances, the disc peripheral fiber ring will lose elasticity, bulging around the formation of the disc bulge. This is similar to the image of a bicycle tire rupturing on the outside and bulging out on the inside. If the disc is pressed again, the annulus fibrosus of the bulging portion of the disc loses its elasticity completely and tears, and the nucleus pulposus (Nucleus pulposus), the content of the disc, spills out of the tear into the surroundings of the annulus fibrosus. This is the medical term for a herniated disc, and the nucleus pulposus is the main component of a herniated disc. As mentioned earlier, the nucleus pulposus is composed of more than 95% water, which is relatively easy to absorb and metabolize in the body. However, other substances in the herniated material besides water are difficult to be removed by the body. Over time, this material will gradually lose water in the body and harden and degenerate to form calcified material. This kind of event occurs in the cervical spine is what you call cervical disc herniation calcification.
