Intervertebral disc calcification is a condition in which the intervertebral disc between two vertebral bodies is altered by trauma, strain, infection, and other factors, resulting in local bone metabolism, causing degeneration of the disc and deposition of calcium salts. In turn, the nucleus pulposus within the disc shrinks, resulting in calcification of the tissue. It occurs in childhood and may be due to the following factors: 1) trauma, injury to the spine due to external forces, localized hemorrhage and hematoma, and later hematoma mechanization to gradually form calcification. 2) infection, due to bacterial or tuberculosis bacillus infection, resulting in calcium salt deposition in the intervertebral disc to form calcification. 3) congenital factors, most of the calcification of the intervertebral disc has congenital spondylolisthesis and foot deformity. 4, local repetitive strain, due to excessive activity and cold and other factors, resulting in local sterile inflammatory reaction, will also cause changes in the intervertebral disc.
