Restore spinal motion without fusion—advanced artificial disc surgery from NYSI.
What Is Total Disc Replacement?
Total disc replacement (TDR), also known as artificial disc replacement, is a minimally invasive spine surgery that removes a worn or herniated disc and replaces it with a biomechanical implant. Unlike spinal fusion, which permanently locks vertebrae together, TDR preserves natural spinal mobility—a major advantage for patients who lead active lifestyles.
TDR is most commonly performed in the cervical (neck) or lumbar (lower back) spine and may be recommended when conservative treatments have failed.
