Paralysis does not usually occur with lumbar calcification. Calcification of lumbar spine is a common degenerative change of lumbar spine, which is commonly seen in long-term physical labor, calcium salt deposition in lumbar spine of middle-aged and old people. Paralysis is mostly caused by nerve damage due to trauma-induced lumbar spine fracture and rupture. Calcification of lumbar vertebrae indicates that the morphology of lumbar vertebrae has changed, and some patients do not have symptoms and will not cause adverse reactions; some patients may have lumbar vertebrae hyperplasia due to lumbar vertebrae calcification, which presses on the spinal cord or nerves, thus causing lumbar pain, leg pain, leg numbness, and other symptoms, but generally does not cause paralysis. If lumbar discomfort occurs, it is recommended to go to the hospital in time for early and regular treatment.
