ABSTRACT:
The intervertebral disc is avascular. With aging, calcified layers occlude the capillaries at the cartilaginous endplates, reducing diffusion of nutrients and oxygen from capillaries into the avascular disc. Under anaerobic condition, excessive production of lactic acid decreases intradiscal pH and irritates surrounding nerves, causing persistent back pain. Antacid is injected into the painful disc to increase pH and alleviate back pain.
