AI/ML Overview

The provided text describes the CHARLOTTE™ Snap-Off Screw and states that its substantial equivalence was confirmed by testing conforming to ASTM F543-02. However, the document does not explicitly state acceptance criteria or provide a detailed study report with device performance metrics against specific criteria.

Therefore, I cannot populate the table with acceptance criteria and reported device performance from the provided text. Additionally, the document does not contain information on sample size, data provenance, expert involvement, adjudication methods, MRMC studies, standalone performance, or training set details.

Based on the provided text, none of the specific details required for your request are available.

The document primarily focuses on:

  • The intended use and device description of the CHARLOTTE™ Snap-Off Screw.
  • Stating its substantial equivalence to a previously cleared device (K043583).
  • Mentioning conformance to ASTM F543-02 as the basis for confirming substantial equivalence, which is a standard for metallic medical bone screws.
  • The FDA's 510(k) clearance letter.

To fully answer your request, a detailed study report or the specific performance data against ASTM F543-02 would be needed.

Dear Mr. Reed:

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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA). it may be subject to such 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 801); 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.

§ 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.
