Detailed Study Protocol Parameters |
Study Objectives |
Objective: To evaluate the 5 year long-term safety and effectiveness of the two-level Simplify Cervical Artificial Disc in subjects with cervical radiculopathy with or without neck pain or myelopathy due to abnormalities localized to the levels of the two contiguous disc spaces that are unresponsive to conservative management. Design: A continuation of the prospective, multi-center, historically controlled IDE study population to evaluate the long-term safety and effectiveness of the Simplify Cervical Artificial Disc.
