Artificial Disc Replacement in Miami
What Is Artificial Disc Replacement?
Artificial disc replacement removes a damaged spinal disc and replaces it with a mechanical implant designed to preserve motion at the treated level. The procedure is most commonly performed in the cervical spine through an incision at the front of the neck. Lumbar disc replacement is offered less frequently and has different selection criteria.
Unlike spinal fusion, disc replacement does not intentionally eliminate motion at the treated segment. However, it is not appropriate for every patient with disc degeneration, neck pain, back pain, or nerve compression.
How Is ACDF Performed?
For cervical disc replacement, the surgeon approaches the spine through an incision at the front of the neck. The damaged disc and tissue compressing the spinal cord or nerve roots are removed. The disc space is prepared, and an appropriately sized artificial disc is positioned between the vertebrae.
Imaging is used to confirm implant position and alignment. The goal is to decompress the neurological structures while maintaining controlled movement at the treated segment.
Who May Be a Candidate?
Disc replacement may be considered for selected patients with symptomatic cervical disc herniation, radiculopathy, or spinal-cord compression involving an approved number of levels. Symptoms and examination findings should correspond with the abnormality seen on imaging.
Candidacy depends on spinal alignment, stability, facet-joint health, bone quality, the number of affected levels, and absence of important contraindications. Significant instability, advanced facet arthritis, severe deformity, osteoporosis, infection, or certain prior operations may make fusion more appropriate.
Potential Benefits
Disc replacement may relieve nerve or spinal-cord compression while preserving motion at the treated level. Motion preservation may reduce stress transferred to neighboring segments, although it cannot prevent all future degeneration. The procedure avoids the need for fusion at the treated level, but it still requires careful patient selection and carries implant-specific risks. Results vary according to the condition, anatomy, implant, and overall health.
Recovery
Walking is encouraged early, and many patients gradually resume routine activities over several weeks. Temporary swallowing discomfort can occur after cervical disc replacement. Activity restrictions and physical therapy recommendations are individualized.
FAQs
Q: Does an artificial disc restore completely normal movement?
A: The implant is designed to preserve controlled motion, but it does not recreate a completely normal or undamaged disc.
Q: Can anyone with a herniated cervical disc receive a replacement?
A: No. Facet arthritis, instability, deformity, poor bone quality, the number of involved levels, and other anatomical or medical factors may limit candidacy.
Q: Can the artificial disc wear out?
A: Artificial discs are mechanical implants and may develop wear, movement, loosening, bone formation, or other problems. Long-term monitoring may be recommended.
Q: Can artificial disc replacement be revised?
A: Revision is possible but may be complex. Depending on the problem, the implant may be repositioned, removed, replaced, or converted to a fusion.
