The system is indicated for use in the temporary stabilization of the anterior spine from C2 to T1 during the development of cervical spinal fusions in patients with: Degenerative Disc Disease, Trauma, Spinal Stenosis, Cervical myelopathy, Deformities or Curvatures, Tumor, Pseudoarthrosis, and failed previous fusion.

Device Description

The Met One Czar Anterior Cervical Plate System is intended for anterior interbody screw fixation of the cervical spine. The Met One Czar Anterior Cervical Plate System includes screws, plates, and a set of instruments to insert the implants. Plates are available in a variety of lengths to accommodate fusion procedures from one to four levels of the cervical spine. Fixation is achieved by inserting the screws through the openings in the plate into vertebral bodies of the cervical spine. Met One Czar plates are manufactured from Titanium 6A1-4V ELI per ASTM F136 and Invibio PEEK-OPTIMA™ LT1 per ASTM F2026.

AI/ML Overview

This document describes a spinal intervertebral body fixation orthosis, specifically the Met One Czar Anterior Cervical Plate System. It is a 510(k) premarket notification for a Class II medical device. As such, the information provided focuses on demonstrating substantial equivalence to legally marketed predicate devices through design, material, and functional comparisons, along with mechanical testing. It does not contain the kind of clinical study details, acceptance criteria tables, expert ground truth adjudication, or human-AI reader studies typically found for AI/ML-driven diagnostic devices.

Therefore, I cannot extract the information required by your request about acceptance criteria and a study proving the device meets those criteria, specifically concerning AI/ML performance.

Here's why:

Device Type: The Met One Czar Anterior Cervical Plate System is a physical implant (spinal plate and screws), not a diagnostic software or AI/ML algorithm.
Regulatory Pathway (510(k)): For this type of device and regulatory pathway, the primary demonstration of safety and effectiveness relies on showing "substantial equivalence" to existing, legally marketed predicate devices, often supported by bench testing (mechanical, material properties) and design comparisons. It does not typically involve clinical trials with human readers, AI assistance, or complex ground truth establishment in the way an AI diagnostic device would.
Information Provided: The document details the device description, intended use, technological characteristics, and notes that substantial equivalence is supported by mechanical testing (static and dynamic compression, static torsion per ASTM F1717). There is no mention of an algorithm, image analysis, diagnostic performance, or human-in-the-loop studies.

In summary, the provided document does not contain the information necessary to answer your questions regarding acceptance criteria, AI/ML device performance studies, sample sizes for test/training sets, expert ground truth establishment, or MRMC studies because the device described is a physical implant, not an AI/ML diagnostic tool.

Dear Mr. Johnson:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part

{1}------------------------------------------------

801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.htm); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4. Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.

For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/) and CDRH Learn (http://www.fda.gov/Training/CDRHLearn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic. See the DICE website (http://www.fda.gov/DICE) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).

Regulation Number and Section

§ 888.3060 Spinal intervertebral body fixation orthosis.

(a)
Identification. A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.(b)
Classification. Class II.
