    Intended Use

    The SMR Reverse Shoulder System is indicated for primary, fracture or revision total shoulder replacement in a grossly rotator cuff deficient joint with severe arthropathy (disabled shoulder). The patient's joint must be anatomically and structurally suited to receive the selected implants and a functional deltoid muscle is necessary to use the device.

    The SMR TT Hybrid Glenoid Reverse Baseplate must not be used in cases of excessive glenoid bone loss and/or when bone graft is needed.

    The Modular SMR Shoulder System allows the assembly of components in various humeral and glenoid constructs. The constructs are intended for cemented and uncemented use as specified in the following table.

    In the Reverse shoulder the humeral construct consists of the humeral stem, the reverse humeral body and the reverse liner. On the humeral side the fixation of the humeral stem determines if the construct is cemented or uncemented.

    The Reverse glenoid consists of a metal back/connector/glenosphere construct or of a peg/baseplate/glenosphere construct.

    Device Description

    The subject SMR Reverse HP Shoulder System is a line extension to the predicate SMR Shoulder System (K223876) consisting of Reverse HP crosslinked UHMWPE glenospheres and Co-Cr-Mo liners. The components are available in one diameter with various options to accommodate varying patient anatomy.

    AI/ML Overview

    Based on the provided FDA 510(k) clearance letter for the SMR Reverse HP Shoulder System, here's an analysis of the acceptance criteria and the study proving the device meets them:

    It's important to note that this document is a 510(k) clearance, which is primarily a declaration of substantial equivalence to a previously cleared predicate device, rather than a full, de novo approval that would detail extensive clinical performance studies with specific statistical acceptance criteria for novel claims. The focus here is on demonstrating that the new device (SMR Reverse HP Shoulder System) is as safe and effective as existing legally marketed devices, rather than proving a new level of clinical efficacy.

    Therefore, many of the specific details you've asked for, such as precise quantitative acceptance criteria for clinical performance (e.g., accuracy, sensitivity, specificity, or effect size for AI assistance), adjudication methods, or detailed expert qualifications for ground truth establishment, are typically not found in a 510(k) summary, as they are not generally required for demonstrating substantial equivalence for an orthopedic implant.

    The "acceptance criteria" for a 510(k) device primarily revolve around demonstrating that the new device performs as intended and is as safe and effective as its predicate. This is primarily done through non-clinical (mechanical) testing and reference to the predicate's established clinical history.


    Acceptance Criteria and Reported Device Performance

    The acceptance criteria for the SMR Reverse HP Shoulder System are implicit in the demonstration of substantial equivalence to its predicate devices. The performance testing aims to show that the new components function equivalently to, or better than, the predicate components within the intended use.

    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance Criteria CategorySpecific Test/AreaAcceptance Standard (Implicit from Substantial Equivalence and Standards)Reported Device Performance (Summary from Document)
    Mechanical PerformanceFatigue TestDevice must withstand anticipated physiological loads and cycles without failure or significant degradation over its intended lifespan, meeting relevant ISO/ASTM standards."Mechanical tests demonstrated that device performance fulfilled the intended use and that the devices are substantially equivalent to the predicate devices."
    Push-Out TestComponents must maintain adequate fixation strength against physiological forces."Mechanical tests demonstrated that device performance fulfilled the intended use and that the devices are substantially equivalent to the predicate devices."
    Wear TestWear rates of bearing surfaces (UHMWPE, CoCrMo) must be within acceptable limits as defined by relevant ISO/ASTM standards and comparable to predicate devices."Mechanical tests demonstrated that device performance fulfilled the intended use and that the devices are substantially equivalent to the predicate devices."
    Creep and Deformation TestMaterials must exhibit acceptable levels of creep and deformation under sustained loads."Mechanical tests demonstrated that device performance fulfilled the intended use and that the devices are substantially equivalent to the predicate devices."

    Particle AnalysisAssessment of wear debris generated by the bearing surfaces to evaluate potential biological reactivity and long-term effects."Mechanical tests demonstrated that device performance fulfilled the intended use and that the devices are substantially equivalent to the predicate devices."
    Range of MotionThe system should allow satisfactory physiological range of motion."Mechanical tests demonstrated that device performance fulfilled the intended use and that the devices are substantially equivalent to the predicate devices."
    BiocompatibilityBiological Safety EvaluationBiocompatibility (cytotoxicity, sensitization, irritation, etc.) must be established according to ISO 10993-1."A biological safety evaluation was conducted per FDA Guidance and ISO 10993-1." (Implicitly met acceptance criteria)
    Material ComplianceMaterial Standards (e.g., Ti6Al4V, CoCrMo, UHMWPE)All materials must conform to specified international standards (ISO, ASTM) for medical implants."Ti6Al4V (ISO 5832-3 - ASTM F1472) – Ti6Al4V 3D printed (to meet the mechanical and chemical requirements of ISO 5832-3) - CoCrMo (ISO 5832-12 - ASTM F1537) – UHMWPE (ISO 5834-2 - ASTM F648) - LimaVit™ (Vitamin E highly crosslinked UHMWPE) (ISO 5834-2 - ASTM F648 - ASTM F2695 – ASTM F2565) - PoroTi Titanium Coating (ASTM F1580) - Ta (ISO13782 - ASTM F560)" (Confirmed compliance)
    Sterility, Packaging, Shelf Life, ReprocessingValidation against established standards.Must be adequately validated."Previously completed sterility, packaging, shelf life and reprocessing validations from the predicate system were leveraged for the subject devices." (Implicitly met acceptance criteria by leveraging predicate data)
    Clinical Performance (Substantial Equivalence)Equivalence in safety and effectiveness to predicate device, as demonstrated through post-market data.Clinical outcomes for the subject device (or its components) must be consistent with the known performance and safety profile of the predicate device."Post-market clinical data from outside the United States on the subject and predicate device were provided in this submission, including patient-level radiographs, outcome measures, and safety data. The data supported a determination of substantial equivalence." (Implicitly met acceptance criteria)

    Study Proving Device Meets Acceptance Criteria

    The study described is primarily a non-clinical performance study combined with a post-market clinical data review for demonstrating substantial equivalence.

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

    • Test Set (Non-clinical): The document states "Mechanical testing was performed on worst case components or constructs." This implies a limited sample size based on engineering principles (e.g., statistical power calculations for specific test types or industry standards for mechanical testing). Specific numbers are not provided, as is typical for 510(k) engineering tests.
    • Data Provenance (Clinical): "Post-market clinical data from outside the United States on the subject and predicate device were provided in this submission." This indicates a retrospective collection of data from clinical use, not a prospective, controlled clinical trial specifically designed for this submission. The exact country of origin within "outside the United States" is not specified, nor is the specific sample size, though it is described as "patient-level radiographs, outcome measures, and safety data."

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

    • Non-clinical: Ground truth is established by engineering standards and specifications (e.g., ISO, ASTM). The "experts" would be the engineers and technicians performing and assessing the mechanical tests against these predefined standards. Their qualifications are implicit in their ability to conduct and interpret these tests, but not explicitly stated in terms terms like "mechanical engineer with 10 years experience."
    • Clinical: For the post-market clinical data, the "ground truth" refers to patient outcomes and safety information. This data is observed in real-world clinical practice, typically by treating physicians. There is no mention of a separate panel of experts specifically adjudicating this post-market data for "ground truth" purposes in the context described.

    4. Adjudication Method for the Test Set:

    • Non-clinical: The "adjudication" is against the pre-defined engineering standards and performance specifications for each mechanical test. This is typically a pass/fail determination based on quantitative measurements. No human-expert consensus "adjudication method" (like 2+1, 3+1) is described or typically applicable to component mechanical testing.
    • Clinical: For the post-market clinical data, there's no mention of an adjudication method by external experts. The data would have been collected as part of routine clinical care or existing registries, and then compiled and analyzed by the manufacturer for the 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 study was done. This device is an orthopedic implant, not a diagnostic imaging AI algorithm. Therefore, MRMC studies and the concept of "human readers improving with AI assistance" are not applicable to the SMR Reverse HP Shoulder System.

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

    • Not applicable. As stated above, this is an orthopedic implant, not an AI algorithm.

    7. The Type of Ground Truth Used:

    • Non-clinical: The ground truth for mechanical testing is based on established engineering principles and international standards (ISO, ASTM) for orthopedic implants. These standards define the expected performance and limits for various mechanical properties.
    • Clinical: The "ground truth" for the clinical data is real-world patient outcomes, safety events, and radiographic assessments collected during post-market use of the predicate device and the subject device (where applicable) outside the US. These are actual clinical observations rather than expert consensus on a test set.

    8. The Sample Size for the Training Set:

    • Not applicable for a 510(k) orthopedic implant. Training sets are relevant for machine learning algorithms. The design and validation of this mechanical implant do not involve "training sets" in this context. The "training" for the device would be the iterative design and development process, informed by biomechanical principles and material science, leading up to the final testing.

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

    • Not applicable. See point 8.

    In summary, the FDA 510(k) clearance for the SMR Reverse HP Shoulder System relies heavily on demonstrating engineering equivalence and material compliance through non-clinical testing, supplemented by a review of existing post-market clinical data for the predicate and related devices. It is a process focused on showing that the new device is "substantially equivalent" to an already cleared device, rather than a de novo approval process that would require extensive novel clinical efficacy studies with sophisticated statistical methodologies often seen for new drug or AI algorithm approvals.

KG.

    AI/ML Overview

    The provided text describes a 510(k) premarket notification for the "MobileLink Acetabular Cup System". This notification is a submission to the FDA to demonstrate that the device is substantially equivalent to legally marketed predicate devices, and therefore does not require a study proving the device meets specific acceptance criteria in the same way a novel device might.

    Instead, the submission relies on non-clinical performance testing and analysis to demonstrate substantial equivalence to predicate devices. There is no mention of specific quantitative acceptance criteria or a dedicated study designed to prove the device meets such criteria with statistical significance.

    Here's an breakdown of the information based on your request, structured to reflect what is actually present in the document:

    1. Table of Acceptance Criteria and Reported Device Performance

    As this is a 510(k) submission for substantial equivalence based on non-clinical testing, there isn't a table of specific, quantitative "acceptance criteria" for clinical performance. The "performance" is demonstrated through various bench tests and characterizations, aiming to show similarity to predicate devices.

    Test TypeObjective / "Acceptance Criteria" (Implied)Reported Performance / Conclusion
    Disassembly Testing (Axial push-out, offset pullout, and torsional tests according to ASTM F1820 for liner/shell assembly)Demonstrate mechanical integrity and resistance to disassembly, comparable to predicate devices.Results indicate the device performs adequately and maintains mechanical integrity as expected for an acetabular cup system. The device is shown to be as safe and effective as the predicate device.

    AI/ML Overview

    This document is a 510(k) Premarket Notification from Medacta International SA for their Mpact® 3D Metal™ Implants and Augments 3D Metal™. It asserts substantial equivalence to predicate devices. It does not describe any studies involving AI or machine learning. Therefore, most of the requested information regarding acceptance criteria, device performance, sample sizes, ground truth, experts, adjudication methods, or MRMC studies for an AI/ML device is not applicable here.

    However, it does describe the non-clinical performance and safety testing conducted for the medical device itself (hip implants and augments), to demonstrate substantial equivalence to predicate devices based on design, materials, manufacturing process, and performance.

    Here's a breakdown of the available information based on your request, with an emphasis that this is for a physical medical device, not an AI/ML system:

    1. A table of acceptance criteria and the reported device performance
    The document states that "Testing was conducted according to written protocols with acceptance criteria that were based on standards." However, the specific acceptance criteria values and the reported device performance values are not provided in this summary document. It only lists the tests performed and the standards they reference.

    2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
    This question is typically for AI/ML performance evaluation. For a physical device like hip implants, "test set" usually refers to the number of physical samples subjected to mechanical testing. This information (specific sample sizes for each test) is not provided in the summary. Data provenance is not applicable here as it refers to physical testing, not patient 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 is not applicable as the "ground truth" for a physical implant's mechanical performance is defined by the established engineering standards (e.g., ASTM, ISO guidelines) against which its physical properties are tested. No human experts are used to "establish ground truth" in this context.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
    Not applicable for physical device mechanical testing.

    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 for AI/ML systems and human reader performance.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
    Not applicable. This is for AI/ML systems.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
    For the mechanical performance of the device, the "ground truth" is defined by adherence to established international and national standards for medical devices and materials, specifically:

    • ASTM F1854-15 (Stereological Evaluation of Porous Coatings)
    • ASTM F1160-14 (Fatigue Shear Testing)
    • ASTM F1044-05 (Static Shear Testing)
    • ASTM F1147-05 (Tensile Strength Testing)
    • ISO 7206-2:1996 (Deformation Testing)
    • ASTM F1820-13 (Locking Mechanism Strength)
    • EN ISO 21535:2009 (Range of Motion Testing)
    • European Pharmacopoeia §2.6.14 and USP chapter (Bacterial Endotoxin Test)
    • USP chapter (Pyrogen Test)

    8. The sample size for the training set
    Not applicable. This is for AI/ML systems.

    9. How the ground truth for the training set was established
    Not applicable. This is for AI/ML systems.


    Summary of what is provided for the physical device:

    The study proving the device meets acceptance criteria consists of non-clinical performance tests conducted according to written protocols and established standards.

    Performed Non-Clinical Tests:

    • Coating Characterization and Testing:
      • Stereological evaluation of porous coatings (ASTM F1854-15)
      • Fatigue shear testing (ASTM F1160-14)
      • Static shear testing (ASTM F1044-05)
      • Tensile strength testing (ASTM F1147-05)
    • Deformation Testing: (ISO 7206-2:1996)
    • Locking Mechanism Strength: (push-out, lever-out, and torque-out tests, ASTM F1820-13)
    • Range of Motion Testing: (EN ISO 21535:2009)
    • Dynamic Compression Testing of acetabular shell and augment assembly
    • Fatigue Testing of the acetabular shell
    • Pyrogenicity:
      • Bacterial Endotoxin Test (LAL test) according to European Pharmacopoeia §2.6.14 (equivalent to USP chapter )
      • Pyrogen test according to USP chapter

    The document concludes that "Substantial equivalence has been demonstrated through a comparison of intended use, design and technological characteristics, as well as performance evaluations." This implies that the device met the acceptance criteria defined by these standards, but the specific results and numeric criteria are not detailed in this summary.

No information about expert qualifications or numbers is provided for this.

    4. Adjudication Method for the Test Set:

    • No adjudication method is mentioned. The "Acceptable" results for the non-clinical tests suggest that the measurements taken during the studies met predetermined specifications without requiring an adjudication process by multiple reviewers.

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

    • No information about a multi-reader multi-case (MRMC) comparative effectiveness study is provided. This device is primarily a surgical planning software and patient-specific instrumentation, not a diagnostic AI intended to assist human readers in image interpretation for improved diagnostic accuracy.

    6. Standalone Performance Study:

    • Yes, a standalone performance was done. The document outlines "Non-clinical testing" for BLUEPRINT™ Patient Specific Instrumentation to "assess that no new safety or effectiveness questions were raised." This testing includes a "Patient Specific Guiding Wire test" and a "Dimensional test of The titanium guide," both of which evaluate the device's performance based on predefined acceptance criteria without human-in-the-loop performance described. The software's ability to measure in preoperative planning and generate a guide matching patient anatomy was validated using cadaver specimens.

    7. Type of Ground Truth Used:

    • The ground truth for the "Patient Specific Guiding Wire test" and "Dimensional test of The titanium guide" appears to be based on device specifications and direct physical measurements taken during cadaver specimen studies. For example, for the guiding wire test, the ground truth would be the ideal or intended version angle, inclination angle, and entry point, against which the device's actual performance is measured. Similarly, for the dimensional test, the ground truth is the specified dimensions of the titanium guide.

    8. Sample Size for the Training Set:

    • No information about a separate training set or its sample size is provided. The document outlines validation studies to assess the device's performance, but it does not detail the development or training of any machine learning components that would typically require a training set. The software mentioned is for pre-operative planning, visualization, measurement, and annotation, and the generation of a 3D file, which might not rely on machine learning in the same way a diagnostic AI would.

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

    • Since there is no mention of a training set, there is no information provided on how its ground truth was established.

    Intended Use

    The Minima S System is indicated for use in partial or total hip arthroplasty and is intended for press-fit (uncemented) use. When used in total hip arthroplasty, the Minima S Stems are intended for use with compatible femoral heads and acetabular components. When used in partial hip arthroplasty, the Minima S stems are intended for use with Lock Bipolar Heads. Hip arthroplasty is intended for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions:

    • non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis and hip dysplasia;
    • rheumatoid arthritis;
    • treatment of femoral head and neck fractures; .
    • revisions in cases of good remaining femoral bone stock.
    Device Description

    The Minima S System is intended for partial or total hip arthroplasty in cementless use. It is a monolithic collarless stem available in 9 sizes (#4-#12) in standard and lateralized versions.
    When used in total hip arthroplasty Minima S stems are coupled to:

    • Biolox Delta femoral heads (object of this submission) or Limacorporate Femoral Heads (K112158) articulating with Limacorporate Cemented Cups (K112158) or
    • Biolox Delta heads (object of this submission) or Limacorporate Femoral Heads (K112158) articulating with Delta TT Acetabular System (K112898).
      When used in partial hip arthroplasty the Minima S femoral stem is coupled to Lock Bipolar Heads (Limacorporate K112158).
      The Minima S stem is made of Ti6Al4V and it has a plasma sprayed titanium coating in the proximal area (ASTM F1472 - ISO 5832-3). The stem is characterized by a 12/14 conical taper to be coupled to Limacorporate Femoral Heads, Biolox Delta femoral heads or Lock Bipolar Heads. In addition necks are lowered to reduce accidental contact between stem and acetabular cups and they are mirror-polished to reduce abrasion of the UHMWPE cups in case of abnormal contact. The stem has a rectangular section and is characterized by a "V" shaped A-P profile to improve adaptability to the most common bone morphologies and to facilitate insertion of the stem in the canal.
      The Minima S System stems is available in standard and lateralized versions with different CCD angles (131° and 134°), offsets and stem lengths.
      Biolox Delta Heads devices are used by surgeons to replace the head of the femur during total or partial hip surgery. They are characterized by a spherical shape and are coupled with the acetabular cup (K112158, K112898) inserted in the acetabulum, in total hip replacement, or with Lock Bipolar Heads (K112158) in partial hip replacement.
      Biolox Delta heads are coupled with the Minima S stems by means of a 12/14 Morse taper. Biolox Delta heads are made of Biolox Delta ceramic and are available with 28, 32 and 36 mm of diameters and in sizes (offsets) S, M, L and XL (XL size available only for head size 36).
    AI/ML Overview

    This document is a 510(k) premarket notification for the Minima S System, a hip replacement device. It primarily focuses on demonstrating substantial equivalence to previously marketed devices rather than presenting the results of a primary clinical study for the Minima S System itself. As such, information regarding acceptance criteria, device performance, and study design elements typically found in a clinical trial report is not present in this document for the Minima S System.

    However, the document does describe non-clinical testing performed to demonstrate substantial equivalence. Based on the provided text, here's an analysis of the relevant sections, acknowledging that many requested fields cannot be filled due to the nature of this submission:


    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance Criteria (Non-Clinical)Reported Device Performance (Non-Clinical)
    Minima S System (Stems):
    Fatigue resistance according to ISO 7206-6Tests results demonstrated the device's ability to perform under expected clinical conditions.
    Fatigue resistance according to ISO 7206-4Tests results demonstrated the device's ability to perform under expected clinical conditions. (Included evaluation of pull-out force for ceramic heads).
    Titanium Plasma Spray coating conformity to FDA guideline and referenced standardsCoating was characterized to verify conformity.
    Biolox Delta Heads:
    Burst strength according to FDA Guidance Document for the Preparation of Premarket Notifications for Ceramic Ball Hip SystemsTests results demonstrated the device's ability to perform under expected clinical conditions.
    Fatigue according to FDA Guidance Document for the Preparation of Premarket Notifications for Ceramic Ball Hip SystemsTests results demonstrated the device's ability to perform under expected clinical conditions.
    Post-fatigue evaluation according to FDA Guidance Document for the Preparation of Premarket Notifications for Ceramic Ball Hip SystemsTests results demonstrated the device's ability to perform under expected clinical conditions.

    Explanation: The document states that the non-clinical tests demonstrated the devices' ability to perform under expected clinical conditions, implying that the acceptance criteria for these tests were met. However, the specific quantitative pass/fail criteria (e.g., maximum deflection, number of cycles survived, minimum pull-out force values, specific burst pressure) are not detailed in this summary.


    Information Not Available or Not Applicable Based on the Provided Document:

    The following information is specifically requested for "the study that proves the device meets the acceptance criteria." Since this document details a 510(k) submission based on substantial equivalence and non-clinical testing, and explicitly states "Clinical testing was not necessary," most of the requested fields related to clinical studies, human reader performance, and ground truth establishment from patient data are not applicable and are therefore left blank or marked as "N/A."

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

      • Sample Size: Not specified for the non-clinical tests. Non-clinical mechanical tests typically use a smaller number of physical samples (e.g., n=3 or n=6 per test condition) rather than a "test set" of patient data.
      • Data Provenance: N/A (Non-clinical mechanical testing).
    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: N/A (No clinical test set requiring expert ground truth in this document).

    3. Adjudication method (e.g. 2+1, 3+1, none) for the test set: N/A (No clinical test set requiring adjudication in this document).

    4. 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 document refers to a hip replacement system, not an AI diagnostic device.

    5. If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable. This document refers to a hip replacement system, not an AI diagnostic device.

    6. The type of ground truth used (expert consensus, pathology, outcomes data, etc): N/A. For the non-clinical tests, the "ground truth" would be the engineering specifications and performance limits defined by the referenced ISO standards and FDA guidance documents.

    7. The sample size for the training set: Not applicable. This document refers to non-clinical testing for a physical medical device, not a machine learning model.

    8. How the ground truth for the training set was established: Not applicable. This document refers to non-clinical testing for a physical medical device.
