There are many types of lumbar disc diseases, including primary lumbar disc diseases and secondary lumbar disc diseases. The primary lumbar disc diseases mainly include lumbar disc bulge, lumbar disc prolapse, lumbar disc herniation, etc., as well as herniation of the disc upward and downward from the end plate, resulting in Hirschsprung’s nodular disease of the adjacent vertebrae. In addition, there are primary discogenic cysts and tumors. Secondary disc diseases include secondary lumbar spinal stenosis caused by posterior protrusion of the lumbar disc and nerve root canal stenosis caused by lateral protrusion of the lumbar disc.
