The provided document is a 510(k) premarket notification from the FDA, clearing the Medacta International S.A. Versacem Acetabular Shell and Double Mobility HC Liners. This type of document does not contain the acceptance criteria or detailed study results for device performance as would be found in a clinical trial report or a comprehensive engineering report.
The 510(k) process primarily demonstrates "substantial equivalence" to a legally marketed predicate device, rather than proving de novo safety and efficacy against predefined clinical acceptance criteria. The "Performance Data" section in the document only lists the types of non-clinical (bench) tests performed.
Therefore, I cannot fulfill most of the requested information based on this document. Below is a breakdown of what can be inferred or what is explicitly stated, and what cannot be provided:
Inferences/Provided Information from the Document:
- Study That "Proves" Device Meets Acceptance Criteria: The document refers to "Performance Data" from "Nonclinical Studies" (bench testing) to support substantial equivalence. These studies include:
- Design Validation
- Wear Test
- Range of Motion Evaluation
- Fatigue Test
- Pull-off and Lever-out Tests (for liner)
- Evaluation of Jumping Distance
- Evaluation of Impingement Risk
- Pyrogenicity testing (LAL test, in-vivo evaluation in rabbit)
- Biocompatibility assessment
- Shelf-life evaluation
Information NOT available in this document:
- A table of acceptance criteria and the reported device performance: This document only lists the types of tests performed, not the specific acceptance criteria for each test nor the quantitative results. For example, it lists "Wear Test" but doesn't state the acceptable wear rate or the actual wear rate achieved.
- Sample sizes used for the test set and the data provenance: Bench testing results typically refer to the number of samples tested (e.g., how many shells, how many liners), but this is not provided. Data provenance is not applicable as these are bench tests, not clinical studies with human data.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: This is not applicable as these are non-clinical, mechanical/material performance tests, not studies requiring expert interpretation of clinical data or images.
- Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable for non-clinical bench testing.
- If a multi-reader multi-case (MRMC) comparative effectiveness study was done: Not applicable, as this is for a medical device (hip implant), not an AI/imaging device that would involve human readers.
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable for this type of device.
- The type of ground truth used (expert consensus, pathology, outcomes data, etc.): For non-clinical tests, the "ground truth" is typically engineering and material science standards (e.g., force applied, displacement, wear volume, fatigue cycles to failure). These are implied by the test names (e.g., "Fatigue Test" implies testing to a certain number of cycles or until failure, compared against a standard).
- The sample size for the training set: Not applicable. These are physical devices, not AI algorithms trained on data.
- How the ground truth for the training set was established: Not applicable.

Here's an analysis of the provided text in relation to acceptance criteria and supporting studies, though it's important to note that this is a medical device submission, not an AI/ML device submission, so the questions regarding human readers, training sets, etc., are not directly applicable here. The document focuses on mechanical performance and biocompatibility for a physical implant.
1. A table of acceptance criteria and the reported device performance
The document lists performance tests and the standards they adhere to, implying that meeting these standards constitutes the acceptance criteria. However, it does not explicitly state numerical acceptance criteria and does not present specific performance data values in a table format. It merely states that "Testing was conducted according to written protocols with acceptance criteria that were based on standards." and that the studies "demonstrated substantial equivalence."
Here's a generalized representation based on the provided information:
Acceptance Criterion (Implicit) | Reported Device Performance |
---|---|
Conformance to EN ISO 21535:2009 (Range of Motion) | Testing conducted, supporting substantial equivalence. |
Conformance to ISO 7206-4:2010 (Fatigue Testing - Stem) | Testing conducted, supporting substantial equivalence. |
Conformance to ISO 7206-6:2013 (Fatigue Testing - Head/Neck) | Testing conducted, supporting substantial equivalence. |
Conformance to ISO 7206-10:2003 (Static Fatigue - Modular Heads) | Testing conducted, supporting substantial equivalence. |
Conformance to ASTM F2009-00 (Axial Disassembly Force) | Testing conducted, supporting substantial equivalence. |
Conformance to ISO 13779-1:2008 (Coating - Hydroxyapatite) | Testing conducted, supporting substantial equivalence. |
Conformance to ASTM F1147-99 (Tension Testing - Coatings) | Testing conducted, supporting substantial equivalence. |
Conformance to European Pharmacopoeia §2.6.14/USP (BET) | Testing conducted (LAL test), supporting substantial equivalence. |
Conformance to USP (Pyrogen Test) | Testing conducted, supporting substantial equivalence. |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document lists various non-clinical mechanical and coating tests, which typically involve physical samples of the device components. It does not specify the sample sizes (number of stems tested for fatigue, etc.) for each test. The provenance of the data is implicit: it's generated from laboratory testing of the device components. There is no clinical data or patient-derived data mentioned.
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)
This question is not applicable to this type of medical device submission. Ground truth and expert adjudication are relevant for AI/ML diagnostic devices, not for physical implants that undergo mechanical and material testing. The "ground truth" for these tests are the established scientific principles and measurement techniques outlined in the specified ISO and ASTM standards.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This question is not applicable for the same reasons as #3. Mechanical testing results are typically objectively measured and evaluated against a standard, not subject to expert adjudication in the same way as diagnostic interpretations.
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
This question is not applicable as this is not an AI/ML device. No MRMC study was conducted.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This question is not applicable as this is not an AI/ML device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
For the non-clinical tests, the "ground truth" is defined by the specifications and acceptable ranges outlined in the referenced international (ISO) and American (ASTM) standards. For instance, a fatigue test determines if the device can withstand a certain number of cycles at a specific load without failure, as per the standard's requirements. Pyrogenicity is determined by established biological testing methods (LAL test, USP pyrogen test).
8. The sample size for the training set
This question is not applicable as this is not an AI/ML device. There is no concept of a "training set" for a physical implant undergoing mechanical and material characterization.
9. How the ground truth for the training set was established
This question is not applicable as this is not an AI/ML device.

The document does not explicitly state quantitative acceptance criteria in a table format. Instead, it lists general performance tests conducted and then concludes that "Non-clinical testing results support the substantial equivalence claim. The RemedyTM, Pegasus™ and Evolve™ Hip Stems and BiPolar Head are expected to perform adequately during clinical use."
The performance tests conducted include:
Acceptance Criteria (Implied) | Reported Device Performance |
---|---|
Adequate Range of Motion | Verified |
Sufficient Component Connection Strength | Verified |
Low Fretting Corrosion | Verified |
Ceramic Head Burst Resistance | Verified |
Femoral Stem Fatigue Resistance | Verified |
Adequate Coating Characterization | Verified |
Adequate Abrasion Resistance of Coating | Verified |
Adequate Adhesion Strength of Coating | Verified |
Sufficient BiPolar Head Disclamping Resistance | Verified |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document refers to "non-clinical testing and engineering evaluations." This implies in-vitro or bench testing, not patient data. Therefore, concepts like sample size, country of origin, or retrospective/prospective for a patient-based test set are not applicable here. The "test set" would consist of the orthopedic implants subjected to the various physical and mechanical tests. The sample sizes for each specific test are not reported. The company is Australia-based (Signature Orthopaedics Pty Ltd, Lane Cove, NSW 2066, Australia).
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)
This question is not applicable. The device is a physical hip implant. "Ground truth" in this context would refer to the physical and mechanical properties of the device as measured by engineering standards, not expert interpretations of medical images or clinical outcomes.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This question is not applicable as the evaluation involves non-clinical engineering tests, not human interpretation or adjudication of medical data.
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
No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. This type of study is relevant for diagnostic devices that involve human interpretation of medical images, often with AI assistance. The document describes hip implants, which are surgical devices, and the testing performed is non-clinical engineering evaluation.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
No, a standalone algorithm performance study was not done. This question is also relevant for AI/software as a medical device (SaMD) and does not apply to physical hip implants.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For this type of device, the "ground truth" for the non-clinical testing refers to established engineering standards, material properties, and biomechanical principles. For example, fatigue testing would compare the device's performance against known limits for medical implants, and material characterization would be compared against ASTM or ISO standards.
8. The sample size for the training set
This question is not applicable. There is no "training set" as this is not an AI/machine learning device. The "training" in this context would imply the manufacturing and design process of the device itself and the various components.
9. How the ground truth for the training set was established
This question is not applicable for the same reason as point 8. The "ground truth" for the design and manufacturing of the implants would be established through engineering specifications, material selection criteria based on ISO/ASTM standards, and biomechanical research for hip implant design.
