The devices covered by this submission are Stryker and Serf femoral stems, femoral heads, acetabular shells and liner, and Serf acetabular bone screw, to form traditional hip or dual mobility (DM) hip systems. All devices are commercially available and have been cleared in prior 510(k) submissions.

This FDA 510(k) clearance letter details the clearance of Stryker and Serf hip devices. It's important to note that this document is for traditional medical devices (implants) and NOT for a medical device (AI/ML) software. Therefore, many of the requested categories related to AI/ML software performance (like accuracy, F1 score, sample sizes for test/training sets, expert ground truth, MRMC studies) are not applicable to this submission.

The "device" in this context refers to the physical hip implant components. The submission (K250989) is primarily for updating labeling to inform users of compatibility between components from Stryker and Serf, and for adding MR safety information to Serf products.

Here's an analysis of the provided text based on the requested information categories, indicating when a category is not applicable:

1. Table of acceptance criteria and the reported device performance

Since this is for physical hip implant components and primarily a labeling update for compatibility, the "acceptance criteria" and "reported device performance" are based on engineering analyses verifying the physical and functional compatibility and MR safety of the combined components, rather than typical performance metrics for AI/ML software.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• Sample Size for Test Set: Not applicable in the context of clinical images or AI/ML data. The "test set" here refers to the physical samples of the hip implant components and their combinations. The document does not specify the exact number of physical samples tested for each engineering analysis (wear, impingement, etc.).
• Data Provenance: Not applicable in the context of clinical images. The data provenance would be internal laboratory testing results performed by the manufacturer. No country of origin for clinical data is relevant here. The studies were non-clinical (engineering analyses).

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

Not applicable. For physical device compatibility and MR safety, ground truth is established through engineering principles, mechanical testing, and standardized MR safety protocols, not by expert consensus on clinical data.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. No clinical adjudication of results from image analysis is relevant for this type of device submission.

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 is not an AI/ML software device.

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

Not applicable. This is not an AI/ML software device.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

Given the nature of the device (physical hip implants), the "ground truth" for the engineering analyses would be:

• Established engineering standards and specifications: For wear, impingement, range of motion, and femoral head disassembly.
• International standards for MR safety: Such as ASTM standards for MR compatibility testing (e.g., heating, displacement, induced torque, image artifact).

8. The sample size for the training set

Not applicable. This is not an AI/ML software device.

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

Not applicable. This is not an AI/ML software device.

Summary of the Study that Proves the Device Meets Acceptance Criteria:

The study that proves the device meets the (implied) acceptance criteria is a series of non-clinical engineering analyses. The submission states:

• Non-Clinical Testing: "Performance of the subject combinations of Stryker and Serf hip devices were evaluated in a series of engineering analyses. These included wear and articular surface tolerances, impingement, range of motion, femoral head disassembly, and MR safety (including heating, displacement, induced torque, and image artifact)."
• Clinical Testing: "Clinical testing was not required as a basis for substantial equivalence."
• Conclusion on Equivalence: "Based upon a comparison of the intended use, indications for use, design, material, sterilization method, technical and performance characteristics, and operational principles, the Stryker and Serf subject hip devices, when used in the proposed compatible combinations with each other, are substantially equivalent to the predicate devices identified in this premarket notification."

The FDA's clearance is based on the determination that these engineering analyses confirm the safety and effectiveness of the proposed compatible combinations and MR safety, demonstrating substantial equivalence to previously cleared predicate devices. The acceptance criteria are implicit in the successful completion of these standard engineering tests for orthopedic implants.

I am sorry, but the provided text does not contain the detailed information necessary to answer your request about acceptance criteria and the study proving the device meets them.

The document is a 510(k) premarket notification letter from the FDA regarding a medical device called "CI../..X liner for NOVAE® Dual Mobility Acetabular Cup." While it mentions that "Acceptance criteria were met for each test," it does not explicitly state what those acceptance criteria are nor does it provide a detailed description of the study that proves the device meets those criteria.

Specifically, the following information you requested is missing from the provided text:

• A table of acceptance criteria and the reported device performance: The text only generally states that "Acceptance criteria were met."
• Sample size used for the test set and the data provenance: Not mentioned.
• Number of experts used to establish the ground truth and their qualifications: Not applicable for this type of mechanical testing.
• Adjudication method: Not applicable for this type of mechanical testing.
• Multi reader multi case (MRMC) comparative effectiveness study: The document explicitly states "No clinical studies were performed."
• Standalone (algorithm only without human-in-the-loop performance) study: Not applicable as this is a physical medical device, not an AI algorithm.
• Type of ground truth used: For mechanical tests, the ground truth would be the physical measurements themselves against established standards, but details are not provided.
• Sample size for the training set: Not applicable as this is a physical medical device, not an AI algorithm.
• How the ground truth for the training set was established: Not applicable.

The document only lists the types of non-clinical tests performed:

• Dimensional analysis
• Head insertion force
• Head lever out force
• Wear analysis

And states that these tests were conducted to demonstrate substantial equivalence to predicate devices, focusing on design, materials, and mechanical performance according to ASTM standards. It concludes that the device is substantially equivalent based on these non-clinical tests.
