The ATEC Posterior Navigated Disc Prep Instruments are indicated to facilitate discectomy, bony resection, implant selection, and access during spinal surgery. Navigated instruments are specifically designed for use with the Medtronic® StealthStation™ System, which is indicated for any medical condition in which the use of stereotactic surgery may be appropriate and where reference to a rigid anatomical structure, such as vertebra, can be identified relative to a CT or MR based model, fluoroscopy images, or digitized landmarks of the anatomy.
The ATEC Posterior Navigated Disc Prep Instruments are surgical instruments that are designed to be compatible with the Medtronic® StealthStation™ Surgical Navigation System. The navigated disc preparation instruments are intended to facilitate discectomy, and bony resection. The navigated trials are intended to facilitate implant size selection of Alphatec intervertebral body fusion devices during spinal surgery. All instruments are reusable and are offered non-sterile to be cleaned and steam sterilized by the end user.
This document describes the acceptance criteria and study proving the device meets those criteria, based on the provided FDA 510(k) summary for the "ATEC Posterior Navigated Disc Prep Instruments."
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria (General) | Reported Device Performance (Summary of results) |
|---|---|
| Dimensional Analysis: Instruments should meet specified dimensional requirements to ensure compatibility and proper function. | Dimensional analysis of the instruments compared to Medtronic instruments was conducted. |
| Performance with Medtronic StealthStation System: The instruments should perform safely and effectively when used with the Medtronic StealthStation System, ensuring accurate navigation and intended surgical function. | Testing was conducted to confirm performance and safety of the subject instruments when used with the Medtronic StealthStation System. |
| Substantial Equivalence: The device must demonstrate substantial equivalence to legally marketed predicate devices in terms of intended use, indications for use, design, technology, and performance. | Testing results demonstrated the subject ATEC Posterior Navigated Disc Prep Instruments are substantially equivalent when compared to other legally marketed devices cleared by FDA. |
2. Sample Size Used for the Test Set and Data Provenance
The provided document does not specify the exact sample size used for the test set in the performance testing. It generally states that "Dimensional analysis of the instruments compared to Medtronic instruments" and "Testing to confirm performance and safety of the subject instruments when used with Medtronic StealthStation System" were conducted.
The data provenance is not explicitly stated in terms of country of origin or whether it was retrospective or prospective. Given the nature of performance testing for medical devices, it would generally be prospective testing conducted in a controlled environment to verify design specifications and system compatibility.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This information is not provided in the document. For device performance testing, "ground truth" might refer to engineering specifications, established performance benchmarks for predicate devices, or validated measurement techniques. The document does not detail how these "truths" were established or if specific experts were involved in defining them.
4. Adjudication Method for the Test Set
This information is not applicable and therefore not provided. "Adjudication method" typically refers to how discrepancies in human reader interpretations are resolved, which is relevant for studies involving human assessment (e.g., diagnostic image interpretation). This document describes performance testing of surgical instruments and their compatibility with a navigation system, not human interpretation of medical data.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size of How Much Human Readers Improve with AI vs without AI Assistance
No, an MRMC comparative effectiveness study was not done. The device is a set of navigated surgical instruments intended to facilitate discectomy, bony resection, and implant selection, not an AI-assisted diagnostic tool that aids human readers. Therefore, the concept of "how much human readers improve with AI vs without AI assistance" is not relevant to this device.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
This is not applicable in the typical sense of an algorithm. The device is a set of physical surgical instruments designed to be used with a navigation system. The "performance" being evaluated is the physical and functional interaction of the instruments with the navigation system, not an algorithm's standalone diagnostic capability. The closest analogy might be the performance of the navigation system itself (which the instruments are compatible with), but the document focuses on the instruments' performance and safety when used with that system.
7. The Type of Ground Truth Used
For dimensional analysis, the ground truth would be engineering specifications and drawings for the instruments. For performance and safety with the navigation system, the ground truth would involve defined functional and safety criteria based on the intended use and established performance of the Medtronic StealthStation System. This might include measurements of accuracy, precision, and successful navigation outcomes in a simulated or controlled environment. It is not expert consensus, pathology, or outcomes data in the usual clinical trial sense.
8. The Sample Size for the Training Set
This information is not applicable and therefore not provided. The development and testing of these surgical instruments do not involve a "training set" in the context of machine learning or AI models. Performance testing of physical medical devices relies on engineering principles and validation against specifications, not data-driven training.
9. How the Ground Truth for the Training Set Was Established
This information is not applicable, as there is no "training set." The performance of the instruments is validated against established specifications and functional requirements as described in point 7.

Dear Sandy Gill:
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 (the 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 available 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.
