Note: The document provided is a 510(k) summary for medical devices where the primary goal is to demonstrate substantial equivalence to legally marketed predicate devices. As such, the acceptance criteria are generally framed in terms of meeting relevant standards (e.g., ASTM) and showing performance comparable to the predicate devices, rather than specific numerical thresholds presented in this summary. The "reported device performance" is a general statement indicating compliance.

2. Sample Size Used for the Test Set and Data Provenance

The document does not specify the exact sample sizes used for each test. The studies mentioned appear to be mechanical/bench tests, not clinical studies involving human patients. Therefore, information regarding "country of origin of the data" and "retrospective or prospective" is not applicable in the context of clinical data. The tests are laboratory-based.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

Not applicable. The tests performed are mechanical/bench tests to assess the physical properties and performance of the devices. They do not involve expert interpretation or human ground truth establishment.

4. Adjudication Method for the Test Set

Not applicable, as the tests are mechanical/bench tests and do not require adjudication of human assessments.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

No, an MRMC comparative effectiveness study was not done. The document describes bench testing for device characteristics, not studies on human reader performance with or without AI assistance.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done

Not applicable. The devices are physical implants (screws, wires, staples), not algorithms or AI-driven systems.

7. The Type of Ground Truth Used

The "ground truth" for the performance claims is based on engineering standards and mechanical testing results. The devices were tested against established industry standards (such as ASTM F564-10 for Z-Staple, and implied similar standards for other components) and internal specifications designed to demonstrate equivalence to the predicate devices.

8. The Sample Size for the Training Set

Not applicable. The devices are physical implants, not AI/machine learning models that require a training set.

9. How the Ground Truth for the Training Set Was Established

Not applicable. There is no training set for these conventional medical devices.

Dear Mr. Henninger:

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.

Regulation Number and Section

§ 888.3040 Smooth or threaded metallic bone fixation fastener.

(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
