This document is a 510(k) Premarket Notification for a medical device (hip prosthesis). It does not contain information about an AI/ML-driven medical device or a study involving AI/ML performance. Therefore, it is impossible to extract the requested information regarding acceptance criteria and study details for an AI-driven device.

The document primarily focuses on demonstrating substantial equivalence of a new size of a Quadra-P hip prosthesis to previously cleared versions and other predicate devices. The "Performance Data" section details non-clinical mechanical studies (fatigue tests, range of motion, pull-off force, coating tests, pyrogenicity) conducted on the physical device, not on an algorithm's performance. It explicitly states: "No clinical studies were conducted."

To answer the user's request, I would need a document describing the validation of an AI/ML-driven medical device.

This is a 510(k) premarket notification for the "SMS Cementless Stem" (K201673), a hip prosthesis. The document details the device, its intended use, and a comparison to predicate devices, along with performance data.

Here's an analysis of the provided text in relation to your request:

1. Table of Acceptance Criteria and Reported Device Performance

The document outlines various non-clinical performance tests conducted for the SMS Cementless Stem. However, it does not provide specific acceptance criteria values or the quantitative results of these tests in a table format. It only states that the testing was conducted "according to written protocols with acceptance criteria that were based on standards."

Here's what can be inferred for a table, but actual criteria values and results are missing in the document:

2. Sample Size Used for the Test Set and Data Provenance

The document explicitly states: "No clinical studies were conducted." Therefore, there is no test set in the context of human clinical data or patient outcomes. The "performance data" refers to non-clinical mechanical and material tests. The sample sizes for these mechanical tests are not provided in this summary. Data provenance is not applicable here as no human data was used.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

Not applicable as no clinical studies were conducted and no ground truth in the clinical sense was established. The "ground truth" for the non-clinical tests would be the specifications and requirements of the referenced ISO and ASTM standards.

4. Adjudication Method for the Test Set

Not applicable as no clinical studies were conducted which would require adjudication of expert opinions or outcomes.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and its effect size

No MRMC study was mentioned or performed, as "No clinical studies were conducted." This device is a mechanical implant, not an AI or diagnostic tool that would typically undergo MRMC studies.

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

Not applicable. This device is a hip implant, not an algorithm or AI system.

7. The Type of Ground Truth Used

For the non-clinical performance and coating tests, the "ground truth" implicitly refers to the
requirements and specifications outlined in the referenced international standards (ISO and ASTM) and the European Pharmacopoeia/USP chapters. The device is expected to meet these pre-defined engineering and material standards. This is a form of engineering/material specification compliance as ground truth.

8. The Sample Size for the Training Set

Not applicable. This device is a mechanical implant, not an AI or machine learning model that requires a training set.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as there is no training set for this type of medical device's approval.

The hip prosthesis AMIStem-C is designed for cemented use in total or partial hip arthroplasty in primary or revision surgery. Hip replacement is indicated in the following cases:
• Severely painful and/or disabled joint as a result of arthritis, rheumatoid polyarthritis or congenital hip dysplasia
· Avascular necrosis of the femoral head
· Acute traumatic fracture of the femoral head or neck
· Failure of previous hip surgery: joint reconstruction, arthrodesis, partial hip arthroplasty, hip resurfacing replacement or total hip arthroplasty

AMIStem-C is a straight triple tapered cemented femoral stem of rectangular cross-section, for use in total or partial hip arthroplasty for primary or revision surgery. The material is High Nitrogen Stainless steel in accordance with ISO 5832-9. Its superficial feature is a mirror polishing on the neck and the body: the whole body is mirror polished in order to minimize the wear due to the occasional contact between neck and cup, particularly in case of double-mobility cups, and to optimize the load transfer from stem to cement avoiding the stress shielding. The AMIStem-C femoral stem size 00 is a line extension to the stems to the currently marketed Amistem-C product line.

This document is a 510(k) premarket notification for a medical device, specifically a femoral stem for hip replacement. It generally focuses on demonstrating substantial equivalence to a predicate device rather than presenting a standalone study with defined acceptance criteria and detailed performance metrics as one might find in an AI/ML device submission.

Therefore, many of the requested elements (e.g., sample sizes for training/test sets, ground truth establishment methods, expert qualifications, MRMC studies, effect sizes of AI assistance) are not applicable as this submission is for a physical orthopedic implant, not an AI/ML-based diagnostic or treatment device.

However, I can extract the relevant information regarding performance testing that was leveraged from the predicate device to support the substantial equivalence claim.

Here's a breakdown of the requested information based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state numerical "acceptance criteria" and "reported device performance" in the format typically used for AI/ML device evaluations (e.g., sensitivity, specificity, AUC). Instead, it states that the performance testing from the predicate device was leveraged because the new size does not create a new worst-case scenario. The acceptance is implicitly that the device performs equivalently to the predicate and passes the specified ISO standards.

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

These concepts (test set, data provenance, country of origin, retrospective/prospective) are mostly associated with clinical studies or AI/ML evaluations. For this submission, which relies on engineering performance testing of a physical implant and leveraging predicate data:

• Sample Size: Not explicitly stated for each test (e.g., how many stems were tested for fatigue). The "test set" here refers to the physical samples used for the engineering tests.
• Data Provenance: The data is from engineering performance testing based on predicate device data, conducted to international standards (ISO). The specific country of origin for the testing or whether it's retrospective/prospective in a clinical sense is not directly relevant or stated, as it's mechanical testing data leveraged from an already cleared device.

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

Not Applicable. This is an orthopedic implant being cleared based on mechanical performance and substantial equivalence to a predicate, not an AI/ML diagnostic requiring expert interpretation for ground truth.

4. Adjudication method for the test set

Not Applicable. Adjudication methods (e.g., 2+1, 3+1) are used for expert consensus on ground truth in clinical or image-based studies. This submission relies on objective engineering measurements against ISO 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 not an AI/ML 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 device.

7. The type of ground truth used

The "ground truth" for this device's performance is objective compliance with international engineering standards (ISO 7206-4:2010, ISO 7206-6:2013) and established biocompatibility/sterility standards (LAL test, USP ). The performance of the new design (size 00) is considered equivalent if it does not create a "new worst case" compared to the predicate device that has already demonstrated compliance with these standards.

8. The sample size for the training set

Not Applicable. This is not an AI/ML device.

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

Not Applicable. This is not an AI/ML device.

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:

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.
