AI/ML Overview

The provided text describes a medical device, the Osteo 4.0mm Cannulated Screw System, and its 510(k) premarket notification. However, it does not contain information about acceptance criteria or a study proving the device meets acceptance criteria.

The document is a regulatory submission summary for a medical device (a screw system for bone fixation), not a clinical study report or a technical performance evaluation. Regulatory submissions like 510(k)s often demonstrate substantial equivalence to predicate devices, focusing on design, materials, and intended use, rather than presenting novel performance studies against predefined acceptance criteria for AI or software.

Therefore, I cannot fulfill your request for the specific information regarding acceptance criteria and a study proving device performance because that information is not present in the provided text.

The numbered points below reflect that the requested information is absent:

1. Table of Acceptance Criteria and Reported Device Performance: This information is not provided in the document. The document describes a medical device (cannulated screw system) and its intended uses, but it does not specify performance acceptance criteria or report on device performance metrics against such criteria.

2. Sample size used for the test set and the data provenance: Not applicable. This document is a regulatory submission for a physical medical device, not a study involving a "test set" in the context of an AI/ML algorithm.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth establishment for a "test set" is not relevant to this document.

4. Adjudication method for the test set: Not applicable.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This document pertains to a physical medical device (cannulated screw system), not an AI-based diagnostic or assistive tool.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not applicable. This document is not about an algorithm.

7. The type of ground truth used: Not applicable.

8. The sample size for the training set: Not applicable.

9. How the ground truth for the training set was established: Not applicable.

Re : K981259 Osteo 4.0mm Cannulated Screw System Regulatory Class: II Product Code: HWC Dated: April 2, 1998 Received: April 6, 1998

Dear Ms. Staub:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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. Note that labeling or otherwise promoting a device for pedicular screw fixation/attachment would cause the device to be adulterated under 501(f)(1) of This device, if intended for use in pedicular screw the Act. fixation/attachment, would be found not substantially equivalent and would be a class III device under Section ---513 (f) of the Act. Class III devices are required to have an approved premarket approval (PMA) application prior to marketing. Accordingly:

The package insert must prominently state that the device 1. is intended for the specific use(s) described in the enclosure only; and
1. You may not label or in any way promote this device for pedicular screw attachment to, or fixation of the cervical, thoracic or lumbar vertebral column. If this

device is a screw with outer diameters of 3 mm - 10 mm and overall lengths of 10 mm - 75 mm inclusively, the package insert must include the following statement, This device is not approved for screw "WARNING: attachment or fixation to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine." Any pedicular screw fixation/attachment to the cervical, thoracic or lumbar vertebral column of this device is considered investigational and may only be investigated as a significant risk device in accordance with the investigational device exemption (IDE) regulations under 21 CFR, Part 812. All users of the device for pedicular screw fixation/attachment must receive approval from their respective institutional review boards (IRBs) and the Food and Drug Administration (FDA) prior to conduct of the investigation.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major. regulations affecting your device can be found in the Code of Federal Requlations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical General requlation (21 CFR Part 820) and that, Devices: through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP requlation may result in regulatory In addition, FDA may publish further announcements action. concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal Laws or Regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification immediately. An FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4659. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note

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.
