Cervical Artificial Discs

Secure CSeveral cervical artificial discs have been approved by the FDA for use in the United States: Medtronic (Prestige, Bryan), Depuy Synthes (ProDisc –C), Globus (Secure-C), and LDR-Spine (Mobi-C). Clinical outcomes are similar for all manufacturers. In clinical studies comparing cervical fusion to the artificial discs, using FDA criteria, the overall success rate at two years is approximately 80-85% with artificial discs compared to 70-75% for fusion demonstrating that artificial discs are statistically superior to fusion. The design of artificial discs is intended to allow the neck to move in flexion / extension (bending the neck forward and backward), lateral bending (bending the neck side to side) and axial rotation (turning the head side to side) as opposed to fusion surgery where, by definition, some motion is lost.

???????????????????????????Artificial discs are only an option if there are not severe arthritic changes at the level of planned surgery – i.e. large bone spurs, significant loss of disc height or severe deterioration of facet joints. If such changes are present, a fusion procedure is indicated. Some patients with multilevel disease may be candidates for hybrid procedures (a combination of fusion and artificial disc surgeries) or in selected cases off-label use of multilevel artificial disc placement.

Fusion surgery requires postoperative inflammation as part of the bony healing process whereas the inflammation can be abated using anti-inflammatory medications when placing artificial discs. In my experience it has not been unusual for patients with artificial disc surgery to return to light duty work within a couple weeks whereas for fusion surgery this is more typically 6 to 8 weeks though all patients will experience fatigue for a few weeks due to their surgery.
