Federal Register Proposed rule: FDA is proposing to classify posterior cervical screw systems into Class 2 (special controls) and to continue to require premarket notification to provide a reasonable assurance of safety and effectiveness of the device. A posterior cervical screw system is a prescription device used to provide immobilization and stabilization in the cervical spine as an adjunct to spinal fusion surgery. The term “posterior cervical screw systems” is used to distinguish these devices from currently classified pedicle screw spinal systems cleared for use in other spinal regions.
