    Intended Use

    The ExactechGPS is intended for use during preoperative planning and during orthopedic surgeon in locating anatomical structures and aligning the endoprosthesis with the anatomical structures provided that the required anatomical landmarks can be identified on the patient's preoperative CT scan.

    The ExactechGPS Total Shoulder Planning Application is specifically indicated for pre-operative planning of Total Shoulder Arthroplasty using the Equinoxe system. The ExactechGPS Total Shoulder Planning Application permits to visualize, measure and reconstruct anatomical structures in order to select and place the glenoid and humeral components.

    The Exacted GPS Total Shoulder Navigation is specifically indicated for Total Shoulder Arthroplasty using the Equinoxe system to aid the surgeon in locating anatomical structures and aligning the glenoid component with the anatomical structures.

    Device Description

    The ExactechGPS Total Shoulder Application proposed in this submission is a modification of the ExactechGPS Total Shoulder Application cleared per 510(k) #K173372.

    The ExactechGPS Total Shoulder Application is an Image Guided Surgery, or Navigation, system designed to quide surgeons during the preparation of the glenoid as part of a total shoulder arthroplasty procedure. The ExactechGPS Total Shoulder Application also offers a preoperative planning feature that enables surgeons to plan a surgical intervention by evaluating implant size, type, and positioning using reconstructed patient bone models in a virtual environment. The ExactechGPS Total Shoulder Application requires patient CT-scan data to undergo segmentation prior to being imported into the software, as part of reconstructing the bone model, for both navigation and planning.

    In the predicate device, the planning step was only indicated for pre-operative planning of the dlenoid part of the Equinoxe system. This submission proposes the addition of the humeral component. Therefore, the proposed ExactechGPS Total Shoulder Planning Application permits to visualize, measure and reconstruct anatomical structures in order to select and place the glenoid and humeral components.

    The proposed ExactechGPS Total Shoulder Planning and Navigation Applications integrate some other modifications compared to the predicate device. These modifications are documented in Letter to Files.

    The proposed modifications do not change the ExactechGPS System general intended use, general design features, or basic fundamental scientific technology. No changes to the hardware platform or system accessories are proposed by this submission.

    AI/ML Overview

    The provided text is a 510(k) summary for the ExactechGPS Total Shoulder Application. It describes a medical device and its proposed modifications, claiming substantial equivalence to a predicate device. However, it does not include detailed performance data, acceptance criteria, or study methodologies that would allow for a comprehensive description as requested. It only broadly states that "testing information demonstrating safety and effectiveness... is supported by testing that was conducted in-house" and lists general types of software testing (verification and validation).

    Therefore, I cannot provide a complete answer to all parts of your request based solely on the provided document. I will focus on what can be inferred or directly stated from the text.

    Here's an attempt to answer your questions based on the provided document, highlighting where information is missing:

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

    The document states: "Software verification testing to ensure all design outputs meet all specified requirements" and "Software validation to ensure software specifications conform to user needs and intended uses."
    However, the specific acceptance criteria and the reported device performance metrics (e.g., accuracy, precision, sensitivity, specificity, etc.) are not provided in this 510(k) summary.

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

    This information is not provided in the document. The text only mentions "testing that was conducted in-house."

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

    This information is not provided in the document.

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

    This information is not provided in the document.

    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

    The document describes a "surgical navigation system" and "preoperative planning feature," but does not indicate that an MRMC comparative effectiveness study was performed or that human readers' improvement with AI assistance was measured. The focus is on the device's functionality in aiding surgical planning and navigation. Therefore, this information is not applicable or not provided in the context of this 510(k) summary.

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

    The document mentions "software verification testing" and "software validation" which would typically involve testing the algorithm's performance in a standalone manner (e.g., accuracy of bone model reconstruction, implant placement) before integration with the surgeon's input. However, the specific results or detailed methodology for these standalone tests are not provided.

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

    This information is not explicitly provided. Given the nature of a surgical planning and navigation system, ground truth would likely involve highly accurate imaging (e.g., high-resolution CT scans), anatomical measurements, and potentially expert anatomical review for validation of the reconstructed bone models and implant placements. However, the specific method for establishing this ground truth (e.g., expert consensus based on imaging, cadaveric studies with known anatomical landmarks) is not detailed in this summary.

    8. The sample size for the training set

    The document describes modifications to an existing device and its functionalities (e.g., extending planning to the humeral component, extending segmentation capabilities). It does not explicitly mention a deep learning or machine learning system that would require a distinct "training set" in the common AI sense. If the "software" relies on rule-based programming or image processing algorithms, a traditional "training set" might not be applicable in the same way as for a neural network. If there was any machine learning involved, the training set size is not provided.

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

    As the existence or nature of a training set is unclear, the method for establishing its ground truth is also not provided.

    Intended Use

    The Remedy® Shoulder Spacer, which consists of a modular head and stem, is indicated for temporary use (maximum 180 days) as an adjunct to total or hemi-shoulder replacement in skeletally mature patients undergoing a two-stage procedure due to a septic process and where gentamicin is the most appropriate antibiotic based on the susceptibility pattern of the infecting micro-organisms.

    The head and stem components are inserted into the glenoidal cavity and humeral medullary canal, respectively, following removal of the existing prosthetic components and radical debridement. The device is intended for use in conjunction with systemic antimicrobial antibiotic therapy (standard treatment approach to an infection).

    The Remedy® Shoulder Spacer is not intended for use for more than 180 days, at which time it must be explanted and a permanent device implanted or another appropriate treatment performed (e.g. resection arthroplasty, fusion etc.).

    Device Description

    The Remedy® Shoulder Spacer is a sterile, single-use device intended for temporary use (maximum 180 days) as shoulder replacement.

    The Remedy® Shoulder Spacer is composed of two components (a head and a stem) that are intended to be used together to form a temporary shoulder spacer; the components are available in a range of sizes.

    The device is made of fully formed polymethylmethacrylate (PMMA), which is radioopaque and contains gentamicin. The stem component has also an inner stainless steel reinforcing structure.

    The Remedy® Shoulder Spacer provides a functional-mechanical mode of action; it provides patients a temporary implant allowing for a natural range of motion and partial weight-bearing during treatment. It is designed to preserve soft tissue to prevent further complications, such as muscular contraction, and to facilitate the subsequent joint replacement procedure.

    AI/ML Overview

    This document appears to be a 510(k) Summary for a medical device called the "Remedy® Shoulder Spacer." It focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study designed to meet specific acceptance criteria in the way one would for an AI/ML powered device.

    Therefore, many of the requested categories for AI/ML device studies (like sample size for test set, number of experts, adjudication method, MRMC study, standalone performance, training set details) are not applicable to this document as it describes a physical orthopedic implant, not a software algorithm.

    Below is an attempt to map the available information to the closest relevant categories, with explanations for why certain sections are not applicable.


    1. Table of Acceptance Criteria and Reported Device Performance

    As this is not an AI/ML device, the concept of "acceptance criteria" for diagnostic performance metrics (e.g., sensitivity, specificity, AUC) is not present. Instead, the document discusses performance testing designed to demonstrate safe and effective mechanical function and material properties, and equivalence to a predicate device. The "acceptance criteria" would be compliance with relevant standards and demonstration of properties comparable to the predicate.

    Acceptance Criteria (Implied)Reported Device Performance
    Sterilization: Compliance with international standards.Sterilization cycles validated following international standards.
    Shelf Life: Established through stability testing.Established through stability studies. Shelf life is 5 years, same as predicate.
    Biocompatibility: Safe, biocompatible materials for intended use, compliant with ISO 10993 and FDA Draft Guidance.Biocompatibility evaluation performed, showing device materials are safe, biocompatible, and suitable for intended use, taking into account ISO 10993 and FDA Draft Guidance.
    Mechanical Performance: Static and fatigue performance acceptable and comparable to predicate.Performance testing included evaluation of static and fatigue performances. (The document states "The performance data demonstrate that the new devices are substantially equivalent to the predicate device Tecres' Interspace Shoulder" implies these tests met the necessary benchmarks for equivalence).
    Surface Roughness: Acceptable and comparable to predicate.Performance testing included evaluation of surface roughness. (Implied acceptability and equivalence to predicate). Reference devices for surface roughness: Tecres InterSpace Knee (K062273 and K062274) and OsteoRemedies Knee Modular Spacer (K112470).
    Disassembling: Acceptable performance.Performance testing included evaluation of disassembling. (Implied acceptability and equivalence to predicate).
    Antibiotic Elution: Gentamicin elution effective and comparable to predicate.Performance testing included antibiotic (gentamicin) elution testing. (Implied acceptability and equivalence to predicate). The device is made of PMMA containing gentamicin, and the predicate also contains gentamicin. The indications for use specify "where gentamicin is the most appropriate antibiotic."
    Material Composition: Same as predicate.Main Components: Polymethylmethacrylate (PMMA), Methylmethacrylate (MMA), Barium Sulphate (Same as predicate).
    Other Components: Benzoyl peroxide, N,N-Dimethyl-p-toluidine, Hydroquinone (Same as predicate).
    Antibiotics: Gentamicin Sulphate (Same as predicate).
    Inner core: Stainless Steel (AISI 316 ESR) (Same as predicate).
    Design (Shape): Different but functionally equivalent.Design is Head + Stem (separated) for Remedy® vs. Head + Stem (monoblock) for predicate. This is a "Different" characteristic, but the overall performance data is presented to show substantial equivalence.
    Modularity: Different from predicate.Remedy® has 3 heads, 3 stems, offset adjustment vs. None for predicate. This is a "Different" characteristic, but the overall performance data is presented to show substantial equivalence, suggesting the modularity does not negatively impact safety or efficacy.
    Sizes: Different but comparable range.Head Size: Ø: 40 – 45 – 50 mm (Remedy®) vs. Ø: 41 – 46 mm (Predicate).
    Stem Size: L: 101 mm Ø: 7 mm, L: 116 mm Ø: 10.5 mm, L: 131 mm Ø: 14 mm (Remedy®) vs. L: 99 mm Ø: 7 mm, L: 125 mm Ø: 11 mm (Predicate). While "Different," the sizes are intended to cover most shoulder prosthesis configurations currently available, indicating a functional expansion rather than a deviation in core performance.
    Stem-neck angle: Same as predicate.130° (Same as predicate).
    X-ray visibility: Yes (Same as predicate).Yes (Same as predicate).
    Single-use device: Yes (Same as predicate).Yes (Same as predicate).
    Provided Sterile: Yes (Same as predicate).Yes (Same as predicate).
    Sterilization Method: Ethylene Oxide (Same as predicate).Ethylene Oxide (Same as predicate).
    Sterility Assurance Level (SAL): 10-6 (Same as predicate).10-6 (Same as predicate).

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

    This is not applicable for a physical device 510(k) submission in the context of diagnostic "test sets." The performance data is based on laboratory testing of the device itself and its components, according to established engineering and material science protocols. There is no biological "data" in the sense of patient images or clinical outcomes that would have "provenance."


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

    This is not applicable. "Ground truth" in this context refers to a standard of truth for diagnostic or clinical outcome data, which is not evaluated here. The "truth" for device performance is established through physical and chemical testing against engineering standards and comparison to a predicate device.


    4. Adjudication method for the test set

    This is not applicable. There is no clinical "test set" requiring adjudication by experts.


    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 is not applicable as this is not an AI/ML device or a diagnostic device involving "human readers."


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

    This is not applicable as this is not an AI/ML device.


    7. The type of ground truth used

    This is not applicable in the AI/ML sense. The "ground truth" for the device's acceptable performance is defined by:

    • Compliance with recognized standards: e.g., ISO for biocompatibility, sterilization standards.
    • Engineering and material science principles: for mechanical strength, fatigue, material composition.
    • Comparative data to a legally marketed predicate device: demonstrating that the new device is "substantially equivalent" in terms of safety and effectiveness.

    8. The sample size for the training set

    This is not applicable as this is not an AI/ML device. There is no concept of a "training set" for a physical orthopedic implant.


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

    This is not applicable as this is not an AI/ML device.

    Spiral and other fractures of the mid-humerus (in combination with glenohumeral degenerative diseases)
    Revision of failed previous reconstructions when distal anchorage is required
    To restore mobility from previous procedures (e.g. previous fusion)
    The Equinoxe Reverse Shoulder System is indicated for use in skeletally mature individuals with degenerative diseases of the glenohumeral joint and a grossly deficient, irreparable rotator cuff. The Equinoxe Reverse Shoulder is also indicated for a failed glenohumeral joint replacement with loss of rotator cuff function resulting in superior migration of the humeral head.
    The Equinoxe Platform Fracture Stem is indicated for use in skeletally mature individuals with acute fracture of the proximal humerus and displacement of the tuberosities, displaced 3- and 4-part fractures of the proximal humerus (hemi-arthroplasty), or acute fracture of the proximal humerus with failure of the glenohumeral joint (primary total shoulder arthroplasty). The Equinoxe Platform Fracture Stem is also indicated for acute fracture of the proximal humerus in combination with degenerative diseases of the glenohumeral joint and a grossly deficient, irreparable rotator cuff resulting in superior migration of the humeral head (reverse total shoulder arthroplasty). The Equinoxe Platform Fracture Stem is indicated for cemented use only.

    Device Description

    This submission proposes an increase in the angled surface from 12° to 16°, relative to the 12° posterior augment pegged glenoid devices previously cleared via 510(k) K111379. The proposed Exactech Equinoxe Posterior Augment Glenoids are intended to be used with Equinoxe shoulder system components described in #K042021, #K061454, #K093430, #K103419, and #K111379.

    AI/ML Overview

    The provided text describes a Special 510(k) for the Exactech® Equinoxe® UHMWPE 16° Posterior Augment Pegged Glenoids™, which is a modification of a previously cleared device (Exactech Equinoxe UHMWPE 12 Degree Posterior Augment Pegged Glenoid, K111379). The primary change is an increase in the angled surface from 12° to 16°.

    Here's an analysis of the acceptance criteria and study information based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance Criteria (What was measured)Reported Device Performance (Result)
    Mechanical Stability (Dynamic Evaluation of Glenoid Loosening or Disassociation) (via ASTM F2028)Demonstrated safety and effectiveness, supporting substantial equivalence to the predicate device. (Specific quantitative values not provided)
    Cyclic Shear StrengthDemonstrated safety and effectiveness, supporting substantial equivalence to the predicate device. (Specific quantitative values not provided)
    Shear Load to FailureDemonstrated safety and effectiveness, supporting substantial equivalence to the predicate device. (Specific quantitative values not provided)

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

    The document does not specify the sample size (number of devices or tests) used for the mechanical testing.
    The data provenance is from non-clinical performance data (laboratory testing) conducted by the manufacturer, Exactech Inc. It is not patient data (retrospective or prospective) and thus has no country of origin in the clinical sense.

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

    This information is not applicable as the study described is a non-clinical, mechanical testing study, not a clinical study involving expert interpretation of patient data.

    4. Adjudication Method for the Test Set

    This information is not applicable as there was no expert review or adjudication of clinical data. The study was mechanical testing.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    A multi-reader multi-case (MRMC) comparative effectiveness study was not performed. This was a non-clinical mechanical testing study to demonstrate substantial equivalence of a modified medical device.

    6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

    This information is not applicable as the device is a physical implant, not an AI algorithm. Therefore, "standalone" performance in the context of an algorithm is irrelevant.

    7. Type of Ground Truth Used

    The "ground truth" for this study was established through recognized industry standard test methods (ASTM F2028) for evaluating the mechanical properties of glenoid components. This standard defines the criteria for what constitutes acceptable mechanical behavior.

    8. Sample Size for the Training Set

    This information is not applicable as the device is not an AI algorithm and therefore does not have a "training set."

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

    This information is not applicable as the device is not an AI algorithm and therefore does not have a "training set" or ground truth established for one.

    Device Description

    This submission proposes modifying Exactech Equinoxe Cage Glenoid devices cleared via 510(k) #K093430 to change peg geometry and add plasma coating. The proposed Equinoxe Cage Glenoids are intended to be used with the same Equinoxe shoulder system components described in 510(k) #K042021 and 510(k) #K061454 as cited predicates.

    AI/ML Overview

    The provided text describes a Special 510(k) submission for the Exactech Equinoxe® Cage Glenoids™, which proposes modifications to previously cleared devices. The submission focuses on demonstrating substantial equivalence to a predicate device (Exactech Equinoxe Cage Glenoid, K093430) through non-clinical performance data.

    Here's an analysis based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    The acceptance criteria are implied by the mechanical testing standards and the conclusion of substantial equivalence. The "reported device performance" is a statement that the device met these criteria, rather than specific numerical results.

    Acceptance Criterion (Implied by Test Standard)Reported Device Performance
    Mechanical glenoid loosening/disassociation (ASTM F2028)Test results demonstrate substantial equivalence.
    Axial disassembly of modular pegsTest results demonstrate substantial equivalence.
    Resistance of locking mechanism to shear and bendingTest results demonstrate substantial equivalence.
    Plasma coating shear fatigue strength (ASTM F1160)Test results demonstrate substantial equivalence.
    Plasma coating static shear strength (ASTM F1044)Test results demonstrate substantial equivalence.
    Plasma coating static tensile strength (ASTM F1147)Test results demonstrate substantial equivalence.
    Plasma coating abrasion (ASTM F1978)Test results demonstrate substantial equivalence.

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

    • Sample Size: Not explicitly stated. The document mentions "test results and analyses," which are typically derived from a specific number of samples for each mechanical test, but the exact number of units tested for each criterion is not provided.
    • Data Provenance: Not explicitly stated regarding country of origin. The study is a non-clinical performance study (mechanical testing), not a study involving patient data. Therefore, the concepts of "retrospective or prospective" and "country of origin of the data" are not directly applicable in the same way they would be for a clinical study. These are laboratory-based engineering tests.

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

    This information is not applicable to this submission. The "ground truth" for non-clinical mechanical testing is established by adherence to recognized industry standards (e.g., ASTM standards) and the physical properties and performance of the device under specific test conditions. Expert opinion is not used to establish the "ground truth" in the same way it would be for a clinical diagnostic device.

    4. Adjudication Method for the Test Set

    This information is not applicable to this submission. Adjudication methods (like 2+1, 3+1) are used for clinical studies involving human interpretation or subjective assessments, often in diagnostic imaging. Mechanical testing results are objective measurements against predefined 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

    This information is not applicable. This submission is for modifications to a glenoid component (a medical implant), not an AI-powered diagnostic or assistive technology. Therefore, an MRMC study with human readers and AI assistance is entirely irrelevant to this device.

    6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

    This information is not applicable. This is a physical medical device (implant), not an algorithm or AI system.

    7. The Type of Ground Truth Used

    The "ground truth" used for this submission is based on:

    • Adherence to recognized industry standards: Specifically, various ASTM standards for mechanical testing (e.g., F2028, F1160, F1044, F1147, F1978). These standards define the test methods and often acceptable performance ranges for similar devices.
    • Comparison to the predicate device: The fundamental "ground truth" for a 510(k) submission, especially a Special 510(k) for modifications, is demonstrating that the modified device performs equivalently to a legally marketed predicate device, as confirmed by comparing design features, materials, dimensions, and mechanical performance under the same test conditions.

    8. The Sample Size for the Training Set

    This information is not applicable. There is no "training set" in the context of mechanical testing for a medical implant. Training sets are relevant for machine learning algorithms.

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

    This information is not applicable for the same reason as point 8.

    Clinical indications for the PRIMARY (P), LONG/REVISION (L), and FRACTURE (F) humeral components are as follows:
    Rheumatoid arthritis, osteoarthritis, osteonecrosis or post-traumatic degenerative problems
    Congenital abnormalities in the skeletally mature
    Primary and secondary necrosis of the humeral head.
    Humeral head fracture with displacement of the tuberosities
    Pathologies where arthrodesis or resectional arthroplasty of the humeral head are not acceptable
    Revisions of humeral prostheses when other treatments or devices have failed (where adequate fixation can be achieved)
    Displaced three-part and four-part upper humeral fractures
    Spiral and other fractures of the mid-humerus (in combination with glenohumeral degenerative diseases)
    Revision of failed previous reconstructions when distal anchorage is required
    To restore mobility from previous procedures (e.g. previous fusion)
    The Equinoxe Reverse Shoulder System is indicated for use in skeletally mature individuals with degenerative diseases of the glenohumeral joint and a grossly deficient, irreparable rotator cuff. The Equinoxe Reverse Shoulder is also indicated for a failed glenohumeral joint replacement with loss of rotator cuff function resulting in superior migration of the humeral head.
    The Equinoxe Platform Fracture Stem is indicated for use in skeletally mature individuals with acute fracture of the proximal humerus and displacement of the tuberosities, displaced 3- and 4-part fractures of the proximal humerus (hemi-arthroplasty), or acute fracture of the proximal humerus with failure of the glenohumeral joint (primary total shoulder arthroplasty). The Equinoxe Platform Fracture Stem is also indicated for acute fracture of the proximal humerus in combination with degenerative diseases of the glenohumeral joint and a grossly deficient, irreparable rotator cuff resulting in superior migration of the humeral head (reverse total shoulder arthroplasty). The Equinoxe Platform Fracture Stem is indicated for cemented use only.

    AI/ML Overview

    The provided text describes a Special 510(k) submission for the Exactech® Equinoxe® UHMWPE Posterior Augment Pegged Glenoids™. This submission is for a medical device (glenoid component in shoulder arthroplasty) and therefore, the acceptance criteria and study detailed are for mechanical testing to demonstrate substantial equivalence, not for AI/ML device performance.

    Here's the breakdown based on the provided document:

    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance CriteriaReported Device Performance
    Meets requirements specified in ASTM F2028, "Standard Test Methods for Dynamic Evaluation of Glenoid Loosening or Disassociation"Proposed devices meet requirements specified in ASTM F2028.

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

    • Sample Size: The document does not specify the exact sample size for the mechanical testing conducted under ASTM F2028.
    • Data Provenance: The data provenance is "mechanical testing referenced in this submission," implying that the testing was conducted by Exactech, Inc. or a contracted laboratory for the purpose of this submission. It's a prospective test specifically for this device modification. There is no information regarding the country of origin of the data beyond the manufacturer being based in Gainesville, Florida, USA.

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

    This question is not applicable to this type of device and study. The "ground truth" for mechanical testing is established by the specifications and methodologies of the ASTM F2028 standard itself, which is a recognized industry standard for evaluating glenoid loosening or disassociation. It does not involve human expert consensus for interpreting test results in the way an AI/ML diagnostic device would.

    4. Adjudication Method for the Test Set

    This question is not applicable. Adjudication methods like 2+1 or 3+1 refer to how discrepancies in human expert interpretations (e.g., in medical image analysis) are resolved to establish a ground truth. Mechanical testing relies on quantifiable measurements and adherence to a standard protocol, not human adjudication of subjective assessments.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

    No. An MRMC comparative effectiveness study is used to compare the diagnostic performance of human readers, often with and without AI assistance, on a set of medical cases. This submission concerns the mechanical performance of an orthopedic implant, not diagnostic interpretation.

    6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

    No. This concept is relevant for AI/ML algorithms. The device in question is a physical orthopedic implant. The "performance" here refers to its mechanical integrity, not an algorithm's output.

    7. The Type of Ground Truth Used

    The ground truth used is adherence to a recognized industry standard for mechanical performance, specifically ASTM F2028. This standard defines the acceptable parameters and methodologies for dynamic evaluation of glenoid loosening or disassociation.

    8. The Sample Size for the Training Set

    This question is not applicable. There is no "training set" in the context of mechanical testing for a physical medical device. Training sets are used in AI/ML development to train an algorithm.

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

    This question is not applicable, as there is no training set for this type of device submission.
