An Artificial Cervical Disc Replacement is a type of spine surgery in which a spine surgeon removes the damaged disc and replaces it with an artificial disc that closely mimics the natural human disc and allows for natural motion of the spine. These discs serve as a cushion and shock absorber between the vertebrae (bones) in the neck. Once the degenerated or damaged disc is removed it is replaced with an artificial disc. The artificial disc mimics and very closely resembles that of a natural human disc. The artificial disc is made up of a polycarbonate urethane middle surrounded by titanium.
An Artificial Disc Replacement is a suitable option for patients with a prominence of arm symptoms (radiating, burning, tingling and numbness) over isolated neck pain, where their hinges or facet joints in their neck are healthy.
The success rate for artificial cervical disc replacements is over 95 percent. This modern surgical procedure improves strength and resolves numbness and associated arm symptoms (ie; arm weakness, tingling, burning, numbness).
With a spinal fusion, approximately 10 degrees of motion is lost in the neck, per level fused. For example, if a person has three levels of their spine fused, that equates to a 30% loss of natural motion of the spine.
