Intended Use

The cannulated screws may be used for fixation of long bone fractures and for bone reconstruction (i.e. fresh fractures, osteotomy, revision procedure where other treatments or devices have failed, arthrodesis, and in conjunction with other fixation hardware). These cannulated screws are not to be used for spinal application or Carpal Tunnel Sydrome.

Device Description

Various styles of stainless steel and titanium alloy cannulated screws. Screw diameters range from 3.5mm to 8.0mm and 6.5mm to 8.0mm, respectively.

AI/ML Overview

The provided text describes a 510(k) premarket notification for cannulated screws and is a regulatory document, not a study evaluating the performance of an AI-powered medical device. It does not contain information about acceptance criteria or a study proving that a device meets such criteria in the context of AI.

Therefore, I cannot answer the questions about:

  1. A table of acceptance criteria and the reported device performance.
  2. Sample size used for the test set and data provenance.
  3. Number of experts used to establish ground truth and their qualifications.
  4. Adjudication method for the test set.
  5. Whether a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was done.
  6. Whether standalone performance was evaluated.
  7. The type of ground truth used.
  8. The sample size for the training set.
  9. How the ground truth for the training set was established.

This document is about the regulatory clearance of a physical medical device (cannulated screws) based on substantial equivalence to existing devices, not about the performance evaluation of an AI algorithm.

Potential Risks: The risks associated with these devices are the same as with any metallic internal fixation device. These include but are not limited to the following:

-Delayed or nonunion which may lead to breakage of the implant

-Bending or fracture of the implant

-Loosening or migration of the implant

  • -Metal sensitivity, or allergic reaction to a foreign body
    -Limb shortening or decrease in bone density due to compression of the fracture or bone resorption

-Pain, discomfort, or abnormal sensations due to the presence of the device

Dear Ms. Binkley:

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 The general controls provisions of the Act 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 (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 Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements 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 requlations.

§ 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.
