Are you sure you are talking about the discs? In osteoporosis compression fractures are treated by injecting a plastic material that tries to restore the original size of the vertebra. There is the "cage" which is a way to fuse the disc space, and there are artificial discs in trial. They are certainly not "substances". Usually the procedure is to cut away the disc material or osteophyte that is pressing on a nerve root and causing pain.
