The VA 5.0 Positioning Pins are designed for use with Variable Angle LCP plate implants featuring variable angle locking holes that accept 5.0mm variable angle bone screws. Positioning or cerclage pins are intended for use with cerclage monofilament wire or multifilament cable to augment fracture stabilization with plates used in long bone fixation, when screw placement would be inhibited, as in the presence of intramedullary implant.

The Wire Mount is intended for use with cerclage wire to augment fracture stabilization with plates when use of screws is contraindicated, as in the presence of intramedullary implants. The design is a "T" post with a hole perpendicular to the post axis, and a small triangular ridge on the bottom. Placing the post through the dynamic compression screw hole, inserting from the bone side of the plate, creates a stable structure for cerclage wire fixation. The cerclage wire is passed around the bone, through the wire mount hole above the outer surface of the plate, and then twisted with the opposite wire end.

The design of the cerclage positioning pin is an oval body with a hole running perpendicular to the long axis (for use in compression holes), and has a stud protruding from the bottom. By placing the post through the top of the dynamic compression screw hole into a pre-drilled hole in cortical bone a stable structure is created for cerclage wire or cable fixation. The wire or cable is passed around the bone, through the Cerclage Positioning Pin hole above the outer plate surface, and then the wire is twisted or cable is crimped for final securement.

This document describes the premarket notification (510(k)) for DePuy Synthes' MR Conditional Positioning Pins. The primary purpose of this submission is to add MR Conditional information to the device labeling, indicating that the devices are safe for use in an MR environment under specified conditions. The intended use and technological characteristics of the devices remain unchanged from their previously cleared versions.

Here's a breakdown of the requested information:

1. A table of acceptance criteria and the reported device performance:

The acceptance criteria are established by adherence to specific ASTM (American Society for Testing and Materials) standards for evaluating medical devices in Magnetic Resonance (MR) environments. The reported device performance indicates that the devices meet these standards, demonstrating safety under specified MR conditions.

2. Sample size used for the test set and the data provenance:

The document does not explicitly state the numerical sample size for the test set. However, it indicates that testing was performed on "the subject devices" and "the construct" (referring to the device in combination with other materials/implants, where applicable). The data provenance is non-clinical, meaning the testing was conducted in a laboratory setting, not on human subjects. There is no information regarding the country of origin of the data. Given the context of a 510(k) submission to the FDA, it is highly likely these tests were conducted in the US or in a manner compliant with US regulatory requirements. The testing is prospective in the sense that the tests were designed and executed to evaluate the MR compatibility of the devices.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

This submission relies on non-clinical testing and established ASTM standards. Therefore, there are no "experts" in the sense of medical professionals establishing a clinical ground truth for a test set. The "ground truth" is defined by the parameters and acceptance limits set forth in the ASTM standards themselves, which are developed by consensus among experts in the field of MR safety and material science.

4. Adjudication method for the test set:

Not applicable. This is not a human-reader study requiring adjudication of expert interpretations. The tests are physical measurements and observations against pre-defined ASTM standards.

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 submission is for MR Conditional orthopedic implants, not an AI-assisted diagnostic tool. No MRMC study was performed as it is irrelevant to the device's function or regulatory pathway.

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

Not applicable. This is a medical device (orthopedic pin), not a software algorithm. The "standalone" performance refers to the inherent physical properties and behavior of the device in an MR environment, as detailed in the non-clinical testing.

7. The type of ground truth used:

The ground truth for this evaluation is defined by:

• Established ASTM Standards: These are industry-recognized protocols and acceptance criteria for evaluating MR safety. They represent a consensus on what constitutes acceptable performance for medical devices in an MR environment.
• Physical Measurements and Observations: The tests involved direct physical measurements (e.g., temperature, displacement, torque) and visual observations (e.g., image artifacts) of the devices under controlled MR conditions.

8. The sample size for the training set:

Not applicable. This is not a machine learning or AI device that requires a training set. The performance is evaluated through material properties and physical testing.

9. How the ground truth for the training set was established:

Not applicable, as there is no training set for this type of device.

Synthes Cerclage Positioning Pin is intended for use with cerclage monofilament wire and multifilament cable to augment fracture stabilization with plates used in long bone fixation when the use of screws is contraindicated, as in the presence of intramedullary implants.

The Cerclage Positioning Pin is designed for use in dynamic compression screw holes that accept a 4.5 mm bone screw. The Cerclage Positioning Pin (and cerclage wire or cable) can be used with a variety of Synthes plates.

The design of the cerclage positioning pin is an oval body with a hole running perpendicular to the long axis (for use in compression holes), and has a stud protruding from the bottom. By placing the post through the top of the dynamic compression screw hole into a pre-drilled hole in cortical bone a stable structure is created for cerclage wire or cable fixation. The wire or cable is passed around the bone, through the Cerclage Positioning Pin hole above the outer plate surface, and then the wire is twisted or cable is crimped for final securement.

I am sorry, but based on the provided document, there is no information about acceptance criteria or a study that proves the device meets specific performance metrics.

The document is a 510(k) summary for the "Synthes Cerclage Positioning Pin" and primarily focuses on:

• Device identification and classification: Name, common name, classification, and predicate device.
• Description and intended use: How the device works and for what purpose.
• FDA's substantial equivalence determination: The FDA's letter stating that the device is substantially equivalent to a legally marketed predicate device.
• Indications for Use statement.

This type of submission to the FDA (510(k)) aims to demonstrate that a new device is as safe and effective as a legally marketed predicate device. It typically relies on comparison to the predicate rather than on new, extensive performance studies with acceptance criteria as one might see for novel devices or PMAs.

Therefore, I cannot provide the requested table or details about a study, sample sizes, experts, adjudication methods, MRMC studies, standalone performance, or ground truth establishment based on the information given.
