The Trivergent Spinal Fixation System is intended to provide immobilization of a single spinal segment in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of lumbar and sacral spine from L2-S1: degenerative disc disease (DDD) (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); spinal stenosis; and failed previous fusion.
The Trivergent Spinal Fixation System is a pedicle screw system intended to stabilize and immobilize the L2-S1 spinal segments as an adjunct to fusion. The system includes a variety of screws and plates along with guides, guidewires, drills, drivers, handles, and tans.
The Trivergent Spinal Fixation System plates and screws are available in a variety of geometries to accommodate various patient anatomies. The Trivergent screws come in lengths from 45mm to 60mm, and the Trivergent plates come in angles from 60° to 75°.
The Trivergent Spinal Fixation System implants and instruments are provided non-sterile and are to be sterilized by the end user.
The Trivergent Spinal Fixation System implants are machined from Ti-6A1-4V ELI per ASTM F136.
This document describes the Trivergent Spinal Fixation System, a medical device. Based on the provided text, it's a 510(k) Premarket Notification for a Class II medical device, specifically a pedicle screw system. These submissions primarily focus on demonstrating substantial equivalence to a legally marketed predicate device, rather than providing detailed clinical study results for novel AI-powered diagnostics.
Therefore, the information typically found in an AI/ML medical device submission (such as acceptance criteria for AI performance, clinical study design for AI efficacy, expert adjudication, etc.) is not present in this document. The "Performance Testing Summary" section focuses on bench testing of the physical device (e.g., static compression, fatigue testing) and a cadaver usability study, which are standard for orthopedic implants, not AI/ML algorithms.
Based on the provided text, I cannot answer the questions directly as they pertain to an AI/ML device's acceptance criteria and proving its performance.
Here's why and what information is available:
- Device Type: This is a physical orthopedic implant (spinal fixation system), not an AI/ML diagnostic or therapeutic device.
- Regulatory Pathway: 510(k) demonstrates substantial equivalence, primarily through non-clinical (bench) testing and comparison to predicates, not typically extensive human clinical trials to establish efficacy akin to AI-driven diagnostics.
- Lack of AI/ML Specifics: There is no mention of algorithms, machine learning, image analysis, or any other AI-related components.
Therefore, the questions regarding acceptance criteria for AI performance, sample sizes for AI test/training sets, expert ground truth, MRMC studies, or standalone algorithm performance simply do not apply to the content of this particular document.
If this document were for an AI/ML device, the required information would be detailed under sections like "Clinical Performance Data," "Software Validation," or "Algorithm Performance Benchmarks." This document is focused on the mechanical and material properties of a physical implant.

Dear Justin Eggleston:
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/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); 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 https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.
For comprehensive regulatory information about mediation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/medicaldevices/device-advice-comprehensive-regulatory-assistance) and CDRH Learn (https://www.fda.gov/training-and-continuing-education/cdrh-learn). 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 (https://www.fda.gov/medical-device-advice-comprehensive-regulatoryassistance/contact-us-division-industry-and-consumer-education-dice) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).
