This document is a 510(k) premarket notification from the FDA for a medical device called "Alteon® HA Femoral Stems." It's important to understand that a 510(k) is a submission made to the FDA to demonstrate that the device to be marketed is at least as safe and effective as a legally marketed predicate device, not a study proving device performance against specific acceptance criteria in the context of an AI/software device.

Therefore, the requested information pertaining to acceptance criteria and a study proving a device meets acceptance criteria in the context of an AI/software device is not applicable to this FDA submission. This submission is for a physical orthopedic implant (a femoral stem for hip replacement), not a "device" in the sense of an AI algorithm or diagnostic software.

The document focuses on demonstrating substantial equivalence to a previously cleared predicate device, not on proving performance against specific acceptance criteria for a new, innovative diagnostic or AI-driven capability.

Here's a breakdown based on the context of the provided document, addressing why many of the requested fields cannot be filled:

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

   • Acceptance Criteria: Not explicitly stated in the context of performance metrics for an AI/software device. The "acceptance" here is the FDA's determination of substantial equivalence.
   • Reported Device Performance: The document describes non-clinical testing performed to show the new HA coating does not negatively impact the device's essential characteristics, maintaining equivalence to the predicate. Performance is demonstrated through engineering analyses (Range of Motion, Stem Neck Fatigue, Distal Stem Fatigue) and characterization of the new HA coating, ensuring it meets standards like ISO 21535:2007, ASTM F2068-2015, ISO 7206-6:2013, ISO 7206-4:2010, ISO 13779-2, and USP , USP , ANSI/AAMI ST72. No quantitative performance metrics in the sense of sensitivity, specificity, etc., for a diagnostic task are provided or relevant.

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

   • This is not applicable. The "test set" in the context of this 510(k) refers to the physical devices undergoing mechanical and chemical testing. There's no data set of patient images or information from which "data provenance" would be relevant.

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. There is no ground truth, expert consensus, or image review involved for this type of medical device submission. The "ground truth" for a mechanical implant is its physical and chemical properties and mechanical integrity, which are assessed through engineering tests, not expert medical review.

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

   • Not applicable. This refers to adjudication of medical image interpretations, which is not part of this submission. Mechanical testing results are objective measurements against established 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 is for AI-powered diagnostic devices. The device in question is a physical orthopedic implant.

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

   • Not applicable. This is for AI algorithms.

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

   • Not applicable in the sense of a clinical ground truth for a diagnostic device. The "truth" for this device's performance is adherence to established engineering and material standards.

8. The sample size for the training set:

   • Not applicable. There is no AI model or "training set" for this physical implant.

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

   • Not applicable. There is no AI model or "training set" for this physical implant.

Summary of Relevant Information from the Document (Re-framed to align with the FDA 510(k) context):

The submission is for the Alteon® HA Femoral Stems, demonstrating substantial equivalence to the predicate device K162732 Exactech® Alteon® HA Femoral Stems. The key difference is the hydroxyapatite (HA) coating material/process.

The "study" conducted for this submission involves non-clinical testing and engineering analyses to demonstrate that the proposed device performs as intended and is substantially equivalent to the predicate.

Non-Clinical Tests and Analyses Done:

• Engineering analysis of Range of Motion (ROM): Per ISO 21535:2007.
• Engineering analysis of Stem Neck Fatigue Testing: Per ASTM F2068-2015 and ISO 7206-6:2013.
• Engineering analysis of Distal Stem Fatigue Testing: Per ASTM F2068-2015 and ISO 7206-4:2010.
• HA coating characterization: Per ISO 13779-2 and FDA Guidance document, "510(k) Information Needed for Hydroxyapatite Coated Orthopaedic Implants," dated February 1997.
• Bacterial endotoxins: Per USP , USP , and ANSI/AAMI ST72.

Conclusion from Testing:
The non-clinical testing and analysis found that the difference in the applied HA coating does not change the intended use, safety, or performance requirements of the proposed devices, nor does it adversely affect their safety or effectiveness. This supports the claim of substantial equivalence to the predicate device. No clinical testing was submitted.

To reiterate, the framework provided in the request is designed for evaluating AI/software-as-medical-device (SaMD) products, which is not what the Alteon® HA Femoral Stems are.
