I have heard about disc replacements. What are some of the problems associated with them?
Total disc replacements may have several advantages over fusion. There are not long term studies to compare to the other surgeries available for the spine however. The device used is called a prosthesis. Some of the complications include shifting or movement of the disc replacement device from where it was placed, fracture of the vertebral bone, and malplacement of the prosthetic joint. Malplacement of the device can cause device wear, loosening, and wear and tear on adjacent facet joints and discs in the spine. Nerve root compression, and curvature of the spine may also be complications of disc replacement.
