*Federal Register* notice: FDA has made available a final guidance entitled “Classification of Posterior Cervical Screw Systems: Small Entity Compliance Guide.” The document is intended to help small entities comply with the final rule on the classification of posterior cervical screw systems. It says that while posterior cervical screw systems must comply with the special controls, it is not expected that manufacturers of devices already on the market as of 5/1/2019 would need to submit new 510(k)s, 510(k) amendments, or add-to-files to demonstrate conformance with the special controls.
