Preserving Motion in the Spine
Artificial disc replacement (ADR) is a surgical procedure in which a degenerated nerve-compressing spinal disc is replaced with an artificial device. This procedure is often used as an alternative to spinal fusion. While fusion eliminates motion at the painful segment, disc replacement is designed to maintain motion and flexibility, more closely mimicking the natural biomechanics of the spine.
Benefits of Disc Replacement
- Motion Preservation: Allows the spine to move more naturally (bending, twisting).
- Reduced Stress on Adjacent Levels: By maintaining motion, ADR may reduce the stress placed on the discs above and below the surgical site, potentially preventing future degeneration.
- Faster Recovery: In many cases, recovery times can be quicker than with fusion surgery because no bone healing is required.
Am I a Candidate?
ADR is most commonly performed in the cervical spine (neck) but can also be used in the lumbar spine (lower back). Ideal candidates typically have:
- Disc degeneration at only one or two levels.
- No significant joint disease or compression on the nerves.
- No spinal deformity (like scoliosis).
- Healthy bone quality (no osteoporosis).
