Total disc replacement (TDR) is a surgical procedure designed to replace a damaged or degenerated intervertebral disc with an artificial disc. This surgery aims to relieve pain and restore function in the spine, addressing conditions such as severe disc degeneration or herniated discs. The procedure involves removing the damaged disc and inserting a prosthetic disc to maintain normal spinal motion and alignment. Performed by skilled orthopedic or neurosurgeons, TDR can significantly improve mobility and reduce pain for patients with chronic spinal issues.
