    AI/ML Overview

    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.

    AI/ML Overview

    The provided text is a 510(k) summary for the Medacta DM Converter - TiN coated, a component of a total hip joint prosthesis. It primarily focuses on demonstrating substantial equivalence to a predicate device through non-clinical testing.

    Here's an analysis of the acceptance criteria and study aspects based on the provided document:

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

    The document does not explicitly present a table of acceptance criteria with numerical targets. Instead, it lists the types of performance tests conducted and implies that the device satisfied the requirements of these standard tests. The "reported device performance" is not quantified in the document, but rather stated that "design validation and performance testing were conducted to written protocols" and the results support substantial equivalence.

    Implied Acceptance Criteria (based on tests performed):

    Acceptance Criteria CategoryReported Device Performance (Implied)
    Mechanical StabilityPassed ASTM F1820-13 for disassembly forces of modular acetabular devices.
    Corrosion ResistancePassed Fretting corrosion test.
    Range of MotionSatisfied Jumping distance and ROM evaluation rationale.
    Wear PerformancePassed ISO 14242-1 for wear of total hip-joint prostheses.
    Abrasion ResistancePassed ASTM 1978-18 for abrasion resistance of metallic thermal spray coatings.
    Coating AdhesionPassed ISO 20502 for adhesion of ceramic coatings by scratch testing.
    CompatibilitySatisfied Double Mobility Converter Implants Compatibility Extension Rationale.
    BiocompatibilityAssessment conducted (results not detailed, but implied acceptable).
    PyrogenicityPassed Bacterial endotoxin test (LAL) according to European Pharmacopoeia §2.6.14 (equivalent to USP ), and Pyrogen test according to USP . (Note: Not labeled as non-pyrogenic or pyrogen-free).
    Shelf-LifeEvaluation conducted (results not detailed, but implied acceptable).

    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 does not specify the sample sizes used for any of the performance tests.
    The data provenance (country of origin, retrospective/prospective) is not mentioned. All studies appear to be non-clinical (laboratory) studies rather than field data.

    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 information is not applicable as the studies are entirely non-clinical performance and design validation tests for a medical device component. There is no "ground truth" in the clinical sense established by human experts for these types of tests.

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

    This information is not applicable. Adjudication methods are relevant for studies involving human interpretation or clinical outcomes, which are not present in this non-clinical 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

    No MRMC comparative effectiveness study was done. This is a submission for a mechanical implant component, not an AI-assisted diagnostic or treatment device. The document explicitly states: "No clinical studies were conducted."

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

    This question is not applicable as the device is a physical medical implant (a component of a total hip joint prosthesis), not an algorithm or AI system.

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

    For the non-clinical performance tests, the "ground truth" is typically defined by the standards themselves (e.g., ASTM, ISO specifications for material strength, wear rates, and stability). The device either meets the specified performance parameters outlined in these standards or it does not. There is no expert consensus, pathology, or outcomes data involved in establishing "ground truth" for these engineering tests.

    8. The sample size for the training set

    This is not applicable. There is no "training set" as this is a physical medical device and not a machine learning model.

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

    This is not applicable for the reasons stated above.

    AI/ML Overview

    The provided text is a 510(k) summary for a medical device (Amis K Long hip prosthesis), which primarily focuses on demonstrating substantial equivalence to a predicate device rather than presenting a detailed study proving the device meets specific acceptance criteria in the context of AI/ML or diagnostic performance.

    Therefore, the document does not contain the information requested regarding acceptance criteria and a study proving a device meets these criteria in the context of AI/ML performance. Specifically:

    • No acceptance criteria for AI/ML performance are listed. The acceptance criteria mentioned refer to non-clinical performance tests for the physical hip prosthesis (e.g., pull-off strength, fatigue testing).
    • No study proving AI/ML device performance is described. The document explicitly states "No clinical studies were conducted." and describes non-clinical mechanical tests.
    • The requested elements (sample size, data provenance, expert qualifications, etc.) are not applicable in this context as the document is about a physical implant, not an AI/ML diagnostic or assistive device.

    The study described in the document primarily focuses on non-clinical mechanical tests to validate the physical properties of the hip prosthesis, such as pull-off strength, range of motion, and fatigue. These tests adhere to established international standards (ASTM, EN ISO, ISO).

    In summary, the provided text does not contain the information necessary to answer the questions about acceptance criteria and a study proving device performance as they relate to AI/ML or diagnostic accuracy.

    AI/ML Overview

    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:

    Test (Standard)Acceptance Criteria (Not provided explicitly, generally "meet standard requirements")Reported Device Performance (Not provided explicitly, implied "met criteria")
    Range of Motion (EN ISO 21535:2009)Based on standard EN ISO 21535:2009Conducted

    Pyrogenicity - Pyrogen Test (USP chapter )Based on USP chapterConducted

    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.

    AI/ML Overview

    This document describes the premarket notification (510(k)) for the SMS Femoral Stem, a cementless bone-preserving short stem designed for proximal fixation in total or partial hip arthroplasty.

    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

    Intended Use

    The hip prosthesis QUADRA-P is designed for cementless use in total or partial hip arthroplasty; for 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, internal fixation, arthroplasty, hip resurfacing replacement or total hip arthroplasty.

    Device Description

    The Quadra-P implants are line extensions to Medacta's Total Hip Prosthesis – AMIStem-H, Quadra-S, and Quadra-H Femoral Stems (K093944); AMIStem and Quadra - Line Extension (K121011); AMIStem-P, AMIStem-P Collared, and AMIStem-H Proximal Coating Femoral Stems (K173794); Quadra-H and Quadra-R Femoral Stems (K082792); and AMIStem-H Proximal Coating (K161635).

    The Quadra-P implants subject of this submission are comprised of the following products:

    • . Quadra-P STD. Stem sizes 0 - 10;
    • Quadra-P LAT, Stem sizes 0 - 10.
      The Quadra-P implants are part of the Medacta Total Hip Prosthesis system. The Medacta Total Hip Prosthesis system consists of femoral stems, modular femoral heads, and acetabular components. The acetabular components consist of metal cups and liners made of ultra-high molecular weight polyethylene (UHMWPE) or Highcross highly crosslinked ultra-high molecular weight polyethylene (HXUHMWPE). Acetabular components include the Mpact DM (K143453), VersafitCup (K083116 and K092265), VersafitCup CC Trio (K103352), Mpact (K103721 and K132879), Mpact 3D Metal (K171966), and Medacta Bipolar Head (K091967).

    The Quadra-P implants can be combined with the CoCr Ball Heads (K072857 and K080885), Endo Head (K111145), MectaCer Biolox Option Heads (K131518), or with the MectaCer BIOLOX® Forte (K073337) or MectaCer BIOLOX® Delta Femoral Heads (K112115).

    AI/ML Overview

    This document is a 510(k) premarket notification for the "Quadra-P" hip prosthesis, specifically describing the physical and mechanical testing performed to demonstrate substantial equivalence to previously cleared predicate devices. It does not contain information about the performance or acceptance criteria of an AI/Software device, nor does it describe a study involving humans or the establishment of ground truth for such a device.

    Therefore, I cannot extract the information required to answer your questions about acceptance criteria and studies proving the device meets those criteria, as the provided document pertains to a physical medical device (hip prosthesis) and its mechanical engineering performance tests, not an AI or software-based medical device.

    The document discusses:

    • Device Name: Quadra-P (hip prosthesis)
    • Regulation Number: 21 CFR 888.3353 (Hip Joint Metal/Ceramic/Polymer Semi-Constrained Cemented Or Nonporous Uncemented Prosthesis)
    • Performance Data (Non-Clinical Studies):
      • Range of Motion (ROM) testing (EN ISO 21535:2009)
      • Fatigue testing (ISO 7206-4 and ISO 7206-6)
      • Pull off force testing (ASTM F2009-00)
      • Pyrogenicity testing (European Pharmacopoeia §2.6.14/USP and USP )
    • Clinical Studies: "No clinical studies were conducted."

    Since the request is specifically about a device proving it meets acceptance criteria through a study involving a test set, expert ground truth, adjudication methods, and potentially human readers (which implies an AI/Software device or diagnostic device), the provided text is entirely irrelevant to those questions.
