The device description and performance studies focus on the mechanical properties and intended use of a cervical plating system, with no mention of AI or ML.
Yes
The device is used for anterior cervical fixation to treat various medical conditions, indicating a therapeutic purpose to alleviate or cure a disease.
No
The device is described as an implantable cervical plating system used for fixation, not for diagnosing conditions. Its purpose is to physically stabilize the spine, not to detect or identify diseases.
No
The device description explicitly states that the Trifore™ Cervical Plating System consists of bone plates and screws made from titanium alloy, which are physical hardware components.
Based on the provided information, the Trifore™ Cervical Plating System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly describes a surgical implant for fixing the cervical spine. This is a therapeutic device used in vivo (within the body).
- Device Description: The description details bone plates, screws, and instruments for surgical implantation. These are physical devices used during surgery.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, tissue, etc.) to provide information for diagnosis, monitoring, or compatibility testing.
IVD devices are used in vitro (outside the body) to analyze samples and provide diagnostic information. The Trifore™ Cervical Plating System is a surgical implant used in vivo for structural support and fixation.

Device Description
The Trifore™ Cervical Plating System consists of a variety of bone plates and screws. Fixation is achieved by inserting bone screws through the openings in the vertebral bodies of the cervical spine. The Trifore™ Plates include locking pins that cover the heads of the bone screws to reduce the potential for screw back-out. The locking pins come preassembled to the plate. Associated instruments are available to facilitate the implantation of the device. The Trifore™ Cervical Plating System implant components are made from titanium alloy such as described by ASTM F136.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The Trifore™ Cervical Plating System has been tested in the following test modes:
- Static axial compression bending per ASTM F1717-14
- Static torsion per ASTM F1717-14
- Dynamic axial compression bending fatigue per ASTM F1717-14
The results of this non-clinical testing show that the strength of the Trifore™ Cervical Plating System is sufficient for its intended use and is substantially equivalent to legally marketed predicate devices.

§ 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)

Dear Mr. Maxwell:
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. 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
1
Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical devicerelated adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
