    AI/ML Overview

    The provided text is a 510(k) premarket notification for the BLUEPRINT™ Patient Specific Instrumentation, which includes both hardware (Glenoid Guides) and software (Blueprint®). While it describes the device, its intended use, and comparison to predicate devices, it does not contain the detailed performance data or acceptance criteria typically found in a study report.

    Therefore, I cannot provide the requested information regarding specific acceptance criteria, reported device performance, sample sizes for test and training sets, expert qualifications, adjudication methods, or MRMC study details. The document states that "Technological differences between the subject and predicate software devices are supported by software verification and validation activities. These activities include functional tests, validation and compatibility for new implant integration, as well as the validation and reproducibility of anatomical measures, planning measures, planning features, and segmentation." However, it does not present the results or specific criteria of these activities.

    In the absence of a detailed study report within the provided text, I can only state that the document asserts that:

    • Differences in design specifications do not raise different questions of safety and effectiveness over the predicate device as demonstrated in validation testing.
    • The subject device, the BLUEPRINT™ Patient Specific Instrumentation, does not raise new questions of safety or effectiveness.
    • Differences in technological characteristics have been addressed by software verification and validation activities.

    To answer your request, a more detailed study report or validation protocol would be necessary.

    Intended Use

    The Delta Xtend Shoulder Prosthesis is indicated for use in treatment of a grossly deficient rotator cuff joint with: · severe arthropathy and/or; · a previously failed joint replacement and/or: · fracture-dislocations of the proximal humerus where the articular surface is severely comminuted, separated from its blood supply or where the surgeon's experience indicates that alternative methods of treatment are unsatisfactory The patient's joint must be anatomically suited to receive the selected implant(s), and a functional deltoid muscle is necessary to use the device. Delta Xtend hemi-shoulder replacement is also indicated for hemi-arthroplasty if the glenoid is fractured intraoperatively or for the revision of a previously failed Delta Xtend Reverse Shoulder. The metaglene component is HA coated and is intended for cementless use with the addition of screws for fixation. The modular humeral stem and humeral epiphysis components are HA coated and intended for cementless use. All other metallic components are intended for cemented use only.

    Device Description

    The Delta Xtend Reverse Shoulder System consists of humeral stem, modular epiphysis, humeral spacer, humeral cup, glenosphere, metaglene and metaglene screws. The glenosphere and metaglene are used for total reverse shoulder arthroplasty. The humeral spacer can be added between the epiphysis and the humeral cup if necessary. Humeral head can be used in hemi-shoulder arthroplasty in place of the humeral cup and glenoid components.

    AI/ML Overview

    The provided document pertains to the 510(k) premarket notification for the DePuy Delta Xtend™ Reverse Shoulder System, specifically for the addition of lateralized glenosphere components. This document is a regulatory submission for a medical device (a shoulder prosthesis), NOT an AI/ML medical device. Therefore, the information requested regarding acceptance criteria and study proving device performance for an AI/ML device (e.g., sample size for test/training sets, data provenance, expert adjudication, MRMC studies, standalone performance, ground truth sources) is not applicable here.

    The document discusses the substantial equivalence of the new components to predicate devices based on:

    1. Biocompatibility: Confirmed per ISO10993-1.
    2. Range of Motion: Theoretical simulated range of motion analyses showed an increase compared to the predicate non-lateralized glenosphere.
    3. Glenoid Loosening/Disassociation: A study demonstrated substantial equivalency of glenoid fixation performance to the predicate.

    The document explicitly states:

    • "Summary of animal study: Animal study was not necessary."
    • "Summary of clinical study: Clinical study was not necessary."

    This indicates that clinical trials or studies that would involve human patient data, ground truth establishment by experts, or detailed statistical analysis of performance (as would be typical for AI/ML device validation) were not required for this specific 510(k) submission, as it focused on demonstrating substantial equivalence through non-clinical performance and design comparisons.

    Therefore, I cannot extract the information required for an AI/ML device's acceptance criteria and study results from this document.

    Intended Use

    IN ANATOMIC:

    The Aequalis Fx2 humeral stem combined with the Flex Shoulder System humeral head may be used by themselves, as a hemiarthroplasty, if the natural glenoid provides a sufficient bearing surface, or in conjunction with the glenoid, as a total replacement.

    The Aequalis Fx2 is to be used only in patients with an intact or reconstructable rotator cuff, where it is intended to provide increased mobility and to relieve pain. The Aequalis Ex2 is indicated for use as a replacement of shoulder joints disabled by:

    • Rheumatoid arthritis with pain
    • Non-inflammatory degenerative joint disease (i.e. osteoarthritis and avascular necrosis)
    • Correction of functional deformity
    • Fractures of the proximal humerus except for size 50mm(1)
    • Traumatic arthritis
    • Revision of other devices if sufficient bone stock remains except for size 50mm(1)

    IN REVERSE:

    The Aequalis Fx2 is indicated for use as a replacement of shoulder joints for patients with a functional deltoid muscle and with massive and non-repairable rotator cuff-tear with pain disabled by:

    • Rheumatoid arthritis

    • Non-inflammatory degenerative joint disease (i.e. osteoarthritis and avascular necrosis)

    • Correction of functional deformity

    • Fractures of the proximal humerus except for size 50mm(1

    • Traumatic arthritis

    • Revision of the devices if sufficient bone stock remains except for size 50mm( ).. The reversed insert is permitted to be used in the transformation from anatomic to reverse Aequalis Fx2 without the humeral stem, and if it is well fixed, during a revision surgery, for patient with a functional deltoid muscle.

    Device Description

    The Aequalis Fx2 is a non-constrained prosthesis intended for the total or partial replacement of the gleno-humeral articulation.

    The Aequalis Fx2 consists of:

    • in an anatomic configuration, a humeral stem compatible with Flex Shoulder System humeral heads (K122698 ; K140082);

    or

    • in a reversed configuration, a humeral stem and a reversed insert, compatible with Aequalis Reversed/Aequalis Reversed II glenoid implants (K081059; K140478).

    The Aequalis Fx2 is intended for use as:

    • traumatic or pathologic conditions of the shoulder resulting in fracture of the glenohumeral joint,

    including humeral head fracture and displaced 3-or 4-part proximal humeral fractures,

    • in case of bone defect in the proximal part of the humerus,

    • a replacement of shoulder joints in primary anatomic or in primary reverse,

    • a replacement of other shoulder joints devices in case of revisions if sufficient bone stock remains.

    The Aequalis Fx2 also allows for conversions from anatomic to reverse shoulder prosthesis in case of revision.

    This submission corresponds to the design modification related to the Aequalis Fx2 assembly zone (humeral stems and reversed inserts) compatible only with each other. This design modification does not affect the intended use of the device or alter the fundamental scientific technology of the device. The pending humeral stems are compatible with the cleared Flex Shoulder humeral heads and the pending reversed inserts are compatible with the cleared Aequalis Reversed II glenoid implants. There is no change regarding the material of the pending Aequalis Fx2 humeral stems. The design change related to the pending Aequalis Fx2 reversed inserts does not include a titanium locking ring in contrast to the previously cleared Aequalis Fx2 reversed inserts.

    AI/ML Overview

    Here's a breakdown of the acceptance criteria and the study information for the Aequalis Fx2 device based on the provided document:

    This document is a 510(k) premarket notification for a medical device (Aequalis Fx2), which focuses on demonstrating substantial equivalence to a predicate device rather than presenting a clinical study on human-in-the-loop performance or diagnostic accuracy. Therefore, many of your requested points related to AI/algorithm performance (standalone performance, MRMC studies, ground truth establishment for training/test sets, expert qualifications) are not applicable to this type of submission.

    The "study" described here consists of various engineering and physical tests to demonstrate that the modified device's performance is acceptable and comparable to its predicate device.

    1. Table of Acceptance Criteria and Reported Device Performance

    Torque testingEquivalent to the predicate (K141345)Acceptable
    Pull out post fatigue testingEquivalent to the predicate (K030941) before fatigueAcceptable

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

    • Sample Size for Test Set: The document does not specify a numerical sample size in terms of units tested for each validation method. It refers to "the design modification" and "the pending Aequalis Fx2 humeral stem and reversed insert," implying that these tests were conducted on representative samples of the device components.
    • Data Provenance: The tests are described as physical/bench tests conducted by the manufacturer, Tornier S.A.S., which is based in Montbonnot Saint-Martin, France. This is not patient-derived data; it's engineering test data.

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

    This information is not applicable. The "ground truth" for these engineering tests is established by industry standards, engineering specifications, and predicate device performance, not by medical experts interpreting data like in a diagnostic study.

    4. Adjudication Method for the Test Set

    This information is not applicable. Adjudication methods like 2+1 or 3+1 are used in clinical studies for resolving discrepancies in expert interpretations, which is not relevant to the physical testing described here.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, Effect Size of Human Reader Improvement with AI vs. Without AI Assistance

    This information is not applicable. This document is for a shoulder prosthesis and does not involve AI or human reader performance.

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

    This information is not applicable. This document is for a physical medical device (shoulder prosthesis) and does not involve an algorithm.

    7. The Type of Ground Truth Used

    The "ground truth" for these performance tests is based on:

    • Engineering Specifications and Design Requirements: For dimensional comparisons, assembly methods, and convertibility.
    • Predicate Device Performance: For tests like Pull-out and Torque testing, where the modified device's performance is compared for equivalence to previously cleared devices (K030941 and K141345).
    • Failure Criteria: For fatigue testing ("No failure after the test").

    8. The Sample Size for the Training Set

    This information is not applicable. There is no "training set" in the context of an engineering evaluation for a mechanical implant.

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

    This information is not applicable for the same reasons as above.

    • Traumatic arthritis
    • Revision of the devices if sufficient bone stock remains
    Device Description

    The Aequalis Adjustable Reverse Shoulder is a modular version of the Aequalis Reverse shoulder system. The Aequalis Adjustable Reverse Shoulder system has the same indications as Tornier Aequalis AscendTM Modular Reverse Shoulder System K110599.

    The Aequalis Adjustable Reverse Shoulder system contains a set of anatomically sized metaphyseal, spacers, and tapered stems that will be used in conjunction with the existing Aequalis Reverse glenosphere and polyethylene inserts for reversed total shoulder arthroplasty.

    The device will have a series of modular stems and spacers to accommodate a varied patient population. The system will include 10 stems: Five 90mm length (9, 11, 13, 15, 17mm diameter) and five 110mm length stems with 3 options:

    • Uncoated,
    • Hydroxylapatite (HAP) coated,
    • HAP over titanium plasma spray (HAP/Ti PS) coated.

    The Aequalis Adjustable Reverse Shoulder assembly must be used in association with the Aequalis Reversed or Aequalis Reversed II glenoid implants, screws and fracture inserts (K030941, K061439, K081059, K050316, and K082120):

    The purpose of this 510(k) is to add an additional stem configuration that does not have HAP Coating and that has plasma titanium spray coating on a portion of the stem (20mm proximal portion of stem), and has a fluted surface on a portion of the stem instead of the full length of the stem (i.e., the HAP coating and fluted surface on 20mm proximal portion of stem. In addition, an alternate plasma titanium spray coating supplier has been validated to perform this manufacturing operation.

The Aequalis Ascend Reverse Metaphysis is a metal component aimed to articulate as a reverse prosthesis with a specific polyethylene insert. The metal metaphysis is impacted onto the taper of the Diaphyseal Stem and then secured with the Ascend Modular Reverse Assembly Screw. The screw is tightened until it is firmly seated on the Reverse Metaphysis. A Reverse Spacer can be used when the maximum insert thickness does not achieve sufficient tension. During these situations, after impaction of the Reverse Metaphysis on the Diaphyseal stem, the metal spacer is impacted on the taper of the Reverse Metaphysis and then secured with the Ascend Modular Reverse Spacer Assembly Screw. The screw is tightened until it is firmly seated on the Reverse Spacer.

    AI/ML Overview

    This document is a 510(k) summary for the Aequalis® Ascend™ Modular Reverse Shoulder System. It does not describe an AI/ML powered device, but rather a medical implant. Therefore, the requested information about acceptance criteria and study details for an AI/ML device is not applicable or available in this document.

    However, I can extract information related to the device's testing and safety from the provided text, which serves a similar purpose to demonstrating that the device meets certain criteria for market approval.

    Here's an interpretation of the document in the context of device approval, where "acceptance criteria" can be broadly understood as the standards it needed to meet for FDA clearance:

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

    The document does not specify quantitative acceptance criteria with numerical targets. Instead, the device's "performance" is assessed through non-clinical tests to demonstrate substantial equivalence to predicate devices, implying it meets the same safety and effectiveness standards.

    Acceptance Criteria (Implied)Reported Device Performance
    Mechanical integrity under fatigue loadingSuccessfully underwent Fatigue Testing. The results allowed the conclusion that the device is substantially equivalent to predicate devices in terms of safety and effectiveness.
    Resistance to fretting corrosionSuccessfully underwent Fretting Corrosion testing. The results allowed the conclusion that the device is substantially equivalent to predicate devices in terms of safety and effectiveness.
    Stability of assembled componentsSuccessfully underwent Static Disassembly Testing of Reverse Insert. The results allowed the conclusion that the device is substantially equivalent to predicate devices in terms of safety and effectiveness.
    Biocompatibility of materialsMaterials conform to established ASTM and ISO standards (ASTM F 136, ASTM F-1537, ASTM F648, ISO-5834-2).

    2. Sample sized 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 document refers to "non-clinical testing" (Fatigue Testing, Fretting Corrosion, Static Disassembly Testing) but does not specify sample sizes for these tests or their provenance.

    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 to this type of device (a physical implant) and is not provided. "Ground truth" in this context would generally refer to expert-labeled data for AI models, which is not relevant here. The "experts" involved would be engineers and materials scientists performing and evaluating the non-clinical tests.

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

    This information is not applicable to this type of device and is not provided. Adjudication methods are typically used for expert consensus on clinical or imaging data in AI/ML studies.

    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 as this is a physical medical implant, not an AI-powered diagnostic or assistive tool.

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

    This information is not applicable as this is a physical medical implant, not an algorithm.

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

    This information is not applicable in the AI/ML sense. For this device, the "ground truth" for the non-clinical testing is based on established engineering principles, material science standards (ASTM, ISO), and comparisons to previously cleared predicate devices. The safety and effectiveness are inferred from these tests and the device's substantial equivalence to predicates.

    8. The sample size for the training set

    This information is not applicable as this is a physical medical implant, not an AI model requiring a training set.

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

    This information is not applicable as this is a physical medical implant, not an AI model.

    In summary, the provided document describes the FDA 510(k) clearance for a physical medical device (shoulder prosthesis). The core of its approval lies in demonstrating "substantial equivalence" to predicate devices through non-clinical (mechanical and material) testing, rather than through AI/ML performance metrics and studies.
