Artificial Disk Replacement

Artificial disk replacement is an alternative to spinal fusion for people whose back or neck pain hasn’t responded to conservative treatments. The goal of lumbar or cervical disk replacement is to relieve chronic back or neck pain and restore normal function by replacing an injured disk with a new, artificial disk.

The artificial disk is made of polyethylene core – the same material used in artificial hips and knees. It slides between two end plates that are anchored to the vertebrae. The advantages of artificial disk replacement over fusion surgery include better preservation of motion and prevention of arthritis above and below the disk.
