Software:
SurgiCase Shoulder Planner is intended to be used as a pre-surgical planner for simulation of surgical interventions for shoulder orthopedic surgery. The software is used to assist in the positioning of shoulder components. SurgiCase Shoulder Planner allows the surgeon to visualize, measure, reconstruct, annotate and edit pre-surgical plan data. The software leads to the generation of a surgery report along with a pre-surgical plan data file which can be used as input data to design the Materialise Shoulder Guide and Models.

Materialise Shoulder System™ is a patient-specific medical device that is designed to be used to assist the surgeon in the placement of shoulder components during total anatomic and reverse shoulder replacement surgery. This can be done by generating a pre-surgical shoulder plan and, if requested by the surgeon, by manufacturing a patient-specific glenoid guide and models to transfer the glenoid plan to surgery. The device is a system composed of the following:

• a software component, branded as SurgiCase Shoulder Planner. This software is a planning tool used . to generate a pre-surgical plan for a specific patient.
• Materialise Shoulder Guide and Models, which are a patient-specific quide and models that are based ● on a pre-surgical plan. This pre-surgical plan is generated using the software component. Patientspecific glenoid guide and models will be manufactured if the surgeon requests patient-specific guides to transfer the glenoid plan to surgery. The Materialise Shoulder Guide is designed and manufactured to fit the anatomy of a specific patient. A bone model of the scapula is delivered with the Materialise Shoulder Guide. A graft model can be delivered with the Materialise Shoulder Guide. The graft model visualizes the graft-space between implant and bone, based on the pre-operative planning of the surgeon. The graft model serves as a visual reference for the surgeon in the OR.

The provided FDA 510(k) summary (K242813) for the Materialise Shoulder System™ describes a submission seeking substantial equivalence to a previously cleared device (K241143). This submission is primarily for adding compatibility with new implant components rather than introducing a completely new AI capability or significant software change that would necessitate extensive new performance data. Therefore, the document does not contain the detailed information typically found in a study proving a device meets acceptance criteria for an AI/ML product.

Specifically, the document states:

• "The non-clinical performance data has demonstrated that the subject software technological differences between the subject and predicate devices do not raise any different questions of safety and effectiveness." (Page 9)
• "Software verification and validation were performed, and documentation was provided following the 'Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices.' This includes verification against defined requirements, and validation against user needs." (Page 10)
• "Previous testing for biocompatibility, sterility, cleaning, debris, dimensional stability and packaging are applicable to the subject device. Testing verified that the accuracy and performance of the system is adequate to perform as intended. The stability of the device placement, surgical technique, intended use and functional elements of the subject device are the same as that of the predicate device of Materialise Shoulder System™ K241143 and previously cleared devices... therefore previous simulated surgeries using rapid prototyped bone models and previous cadaver testing on previously cleared devices K153602 and K131559 are considered applicable to the subject device." (Page 10)

Given this, I cannot provide detailed answers to many of your questions as the submission relies on the substantial equivalence principle and prior testing rather than new, extensive performance studies for AI/ML.

However, I can extract what is available:

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

The document does not provide a specific table of quantitative acceptance criteria and reported device performance for the current submission (K242813), as it relies on the previous clearance and the assessment that the changes (adding implant compatibility) do not raise new safety or effectiveness concerns.

The general acceptance criterion mentioned is that the "accuracy and performance of the system is adequate to perform as intended." This was verified through previous testing, including "simulated surgeries using rapid prototyped bone models and previous cadaver testing."

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

The document mentions "previous simulated surgeries using rapid prototyped bone models and previous cadaver testing on previously cleared devices K153602 and K131559." It does not specify the sample size for these tests, nor the country of origin of the data or whether it was retrospective or prospective.

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 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

No such MRMC study is mentioned. The device is a "pre-surgical planner" and "surgical instrument" designed to assist the surgeon, but the provided text does not detail comparative effectiveness studies of human readers (surgeons) with and without the AI (planning software) assistance.

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

The software (SurgiCase Shoulder Planner) generates a pre-surgical plan which the "qualified surgeon" can "visualize, measure, reconstruct, annotate, edit and approve" (Page 9). This indicates a human-in-the-loop process. Standalone performance of the algorithm without human interaction is not discussed as it's not the intended use.

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

The document generally refers to "verification against defined requirements, and validation against user needs" and "accuracy and performance of the system is adequate to perform as intended" based on "simulated surgeries using rapid prototyped bone models and previous cadaver testing." This suggests a ground truth established through expert-defined surgical planning parameters and comparison to physical outcomes in the simulated/cadaveric environment, but specifics on how this ground truth was formalized (e.g., expert consensus on optimal planning, precise measurement validation) are not detailed.

8. The sample size for the training set

This device is a surgical planning tool and guides, not a deep learning AI model that requires a "training set" in the conventional sense for image classification or similar tasks. It is based on algorithms that process CT-imaging scans and anatomical landmarks to generate personalized plans and guides. Therefore, the concept of a "training set" for AI/ML is not applicable here in the way it would be for a pattern recognition AI. The software's robustness and accuracy are likely validated through extensive testing against various patient anatomies and surgical scenarios.

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

As explained above, the concept of a training set as typically understood for AI/ML models is not directly applicable to this device based on the provided information.

The software is used to assist in the positioning of shoulder components. SurgiCase Shoulder Planner allows the surgeon to visualize, measure, reconstruct, annotate and edit pre-surgical plan data. The software leads to the generation of a surgery report along with a pre-surgical plan data file which can be used as input data to design the Materialise Shoulder Guide and Models.

This can be done by generating a pre-surgical shoulder plan and, if requested by the surgeon, by manufacturing a patient-specific glenoid guide and models to transfer the glenoid plan to surgery. The device is a system composed of the following:

• a software component, branded as SurgiCase Shoulder Planner. This software is a planning tool used to generate a pre-surgical plan for a specific patient.
• Materialise Shoulder Guide and Models, which are a patient-specific guide and models that are based on a pre-surgical plan. This pre-surgical plan is generated using the software component.

The provided text describes a 510(k) submission for the Materialise Shoulder System™, Materialise Shoulder Guide and Models, and SurgiCase Shoulder Planner. It indicates that this is a special 510(k) submission, meaning it's for a modification to a previously cleared device. Therefore, much of the performance data refers back to the predicate device and prior clearances.

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

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

The document does not explicitly state quantitative acceptance criteria or a direct table showing "acceptance criteria vs. reported device performance" for this specific 510(k) submission. Instead, for this special 510(k), the performance data mainly focuses on demonstrating that the changes (addition of new implant components to the software and hardware compatibility) do not raise new questions of safety and effectiveness compared to the predicate device.

The "performance data (non-clinical)" section highlights that:

• Hardware: Previous testing for biocompatibility, cleaning, debris, dimensional stability, and packaging is applicable. Accuracy and performance of the system were "adequate to perform as intended." Previous simulated surgeries and cadaver testing on earlier cleared devices are considered applicable.
• Software: Software verification and validation were performed "against defined requirements" and "against user needs," following FDA guidance.

Since this is a special 510(k) for an incremental change (adding compatibility with specific new implants), it's implied that the acceptance criteria are met if these additions do not negatively impact the established safety and effectiveness of the existing device, and the software development process meets regulatory standards.

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

• Hardware (previous testing cited): The document mentions "previous simulated surgeries using rapid prototyped bone models" and "previous cadaver testing on previously cleared devices K153602 and K131559." It does not specify the sample size for these previous studies (e.g., number of bone models or cadavers) or their provenance (country of origin), nor does it state if they were retrospective or prospective.
• Software (verification and validation): The document states "Software verification and validation were performed," but does not specify a separate "test set" in the context of clinical data or specific performance metrics with sample sizes for this particular submission. The V&V activities would involve testing against requirements and user needs, which could include various test cases and scenarios, but these are not quantified here as a "test set" size.

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 provided in the document. The studies cited for hardware ("simulated surgeries" and "cadaver testing") and software ("verification and validation") do not detail the involvement of experts in establishing ground truth, their number, or specific qualifications. The software's function is to assist surgeons in planning, implying surgeon input in its use, but not explicitly in establishing a ground truth for a test set described in this submission.

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 does not mention any MRMC comparative effectiveness studies. The device (SurgiCase Shoulder Planner software component and Materialise Shoulder Guide and Models hardware component) is designed to assist surgeons in planning and component positioning, but the provided text does not contain data on whether human readers/surgeons improve with or without this specific AI assistance or effect sizes.

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

The document states that the SurgiCase Shoulder Planner is "intended to be used as a pre-surgical planner for simulation of surgical interventions for shoulder orthopedic surgery. The software is used to assist in the positioning of shoulder components." It also mentions, "SurgiCase Shoulder Planner allows the surgeon to visualize, measure, reconstruct, annotate and edit pre-surgical plan data." This indicates that the software is a human-in-the-loop device, where the surgeon is actively involved in the planning process and responsible for approving the plan. Therefore, a standalone (algorithm only) performance assessment, without human input, is unlikely to be the primary method of evaluation described or required for this type of device. The document does not provide such standalone performance data.

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

The document does not explicitly state the type of ground truth used for any specific test set related to this submission. For the hardware (guides and models), the "accuracy and performance" implies a comparison to a known standard or ideal, perhaps derived from anatomical models or surgical goals. For the software, "verification against defined requirements, and validation against user needs" suggests that the ground truth for V&V would be the successful adherence to these requirements and user expectations, which could involve internal expert review or adherence to pre-defined medical/engineering specifications. However, specific types of ground truth like pathology or long-term outcomes data are not mentioned.

8. The sample size for the training set

This information is not provided in the document. As the submission is for a special 510(k) updating compatibility, it's possible that the core algorithms were developed and trained previously, and details of their original training are not part of this specific submission. The focus here is on the impact of the changes to the device.

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

This information is not provided in the document. Similar to the training set size, the specifics of how the ground truth was established for the original training of any underlying algorithms are not included in this special 510(k).

The provided text describes the regulatory clearance for the Materialise Shoulder System™ and mentions performance data, but it does not contain a detailed study proving the device meets specific acceptance criteria in the format requested.

The document is a 510(k) summary, which focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than presenting a comprehensive standalone study with detailed effectiveness metrics.

Here's an analysis of the information that can be extracted, and what is missing based on your request:

1. Table of Acceptance Criteria and Reported Device Performance:

• Acceptance Criteria: Not explicitly stated in a quantitative manner for the performance of the AI component (SurgiCase Shoulder Planner) or the hardware (Materialise Shoulder Guide and Models) beyond ensuring it performs "as intended" and maintains accuracy.
• Reported Device Performance: The document states that "Testing verified that the accuracy and performance of the system is adequate to perform as intended." However, no specific performance metrics (e.g., accuracy, precision, sensitivity, specificity, or error margins) are provided for either the software for planning or the hardware for guiding.

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

• Test Set Sample Size: Not specified for the software component (SurgiCase Shoulder Planner).
• Data Provenance: Not specified for any software testing.
• For Hardware: It refers to "simulated surgeries using rapid prototyped bone models and previous cadaver testing." No specific number of models or cadavers is provided, nor is the country of origin or whether it was retrospective or prospective.

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

• Number of Experts: Not specified.
• Qualifications of Experts: Not specified.

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

• Not specified.

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 is mentioned. The document focuses on the planning and guidance aspect for surgeons, but not on a comparative study of human readers (surgeons) with and without AI assistance for diagnosis or planning accuracy.

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

• A standalone performance evaluation of the software's planning functionality is implied through the statement "Software verification and validation were performed, and documentation was provided following the 'Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices.'" However, no specific metrics or study details are provided. The software is described as a "planning tool used to generate a pre-surgical plan" and for "assisting the surgeon in positioning shoulder components," suggesting a human-in-the-loop workflow.

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

• Ground Truth Type: Not explicitly stated for the software. For the hardware, the use of "rapid prototyped bone models and previous cadaver testing" implies a physical ground truth for accuracy validation.

8. The sample size for the training set:

• The document does not mention a training set sample size, which is typical for AI/ML models. This suggests the software functionality described (planning, visualization, measurement) might not be based on deep learning/machine learning that requires explicit training data in the same way as, for example, an image classification algorithm. It seems to be a rules-based or physics-based planning software.

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

• As no training set is mentioned, the method for establishing its ground truth is also not provided.

In summary:

The provided text from the FDA 510(k) summary states that non-clinical performance testing indicates the device is as safe and effective as its predicate. It mentions software verification and validation and previous hardware testing (biocompatibility, sterility, cleaning, debris, dimensional stability, packaging, simulated surgeries, cadaver testing). However, it lacks the specific quantitative acceptance criteria and detailed study results (such as sample sizes, expert qualifications, clear performance metrics, ground truth establishment for software, and formal comparative effectiveness study results) that are typically expected when describing a study proving specific acceptance criteria in detail. This information is usually found in separate, more detailed technical documentation submitted to the FDA, not in the public 510(k) summary.

The provided text describes the regulatory clearance of a medical device, the INHANCE™ Reverse Shoulder System, and does not contain information about the performance of an AI/ML device. Therefore, it is not possible to answer the requested questions about acceptance criteria, study details, and AI performance.

The document focuses on demonstrating "substantial equivalence" of the device to previously cleared predicate devices through non-clinical testing. It explicitly states: "Clinical testing was not necessary to demonstrate substantial equivalence of the INHANCE™ Reverse Shoulder System to the predicate devices."

The non-clinical testing performed includes:

• Range of Motion (RoM) Evaluation: Met established specifications per ASTM F1378.
• Construct Fatigue Testing: Met acceptance criteria per ASTM F1378.
• Construct Loosening and Disassociation: Met acceptance criteria per ASTM F2028-17.
• Biocompatibility Assessments: Found to be biocompatible per ISO 10993-1 and FDA Guidance.
• Porous Structure Characterization: Identical to previously cleared devices.
• Characterization of VE-UHMWPE: Fully characterized in a previous submission (K202716).
• Evaluation of Wear Rate: Wear rate was lower than a predicate device, meeting acceptance criteria.
• MRI Compatibility: Quantitative data obtained per ASTM standards (F2052-15, F2213-17, F2182-19e2, F2119-07).
• Shelf Life Evaluation: A five-year shelf life established per ISO 11607-1 and ISO 11607-2.
• Sterilization Validation: Sterility Assurance Level (SAL) of 10^-9 found per ISO 11137-1 and ISO 11137-2.

These are all engineering and material performance tests for a physical implant, not an AI/ML algorithm or software.

The Humelock Reversed Shoulder is indicated for primary, fracture or revision total shoulder arthroplasty for the relief of pain and to improve function in patients with a massive and non-repairable cuff tear.

The patient's joint must be anatomically suited to receive the selected implants and a functional deltoid muscle is necessary to use the device.

During primary or revision surgery, if the glenoid bone stock appears to be insufficient to bear the reversed glenoid components or the glenoid bone fractures during the procedure, a taper adapter can be used to convert the Humelock Reversed Shoulder to an anatomic hemi-shoulder prosthesis.

The humeral stem of the Humelock Reversed Cemented Shoulder Prothesis is intended for cemented use only. The humeral stem of the Humelock Reversed Cementless Shoulder Prothesis is lockable with two cortical bone screws and is intended for cementless use only. An optional anti-rotational spoiler can be used with either the cementless or the cemented stems.

The glenoid baseplate and post extension are intended for cementless use with the addition of screws for fixation.

In an anatomic shoulder configuration, the Humeris Shoulder System is indicated for use in total and hemi-shoulder replacement to treat:

• A severely painful and/or disabled joint resulting from osteoarthritis or rheumatoid arthritis;

• Other difficult clinical problems where shoulder arthrodesis or resection arthroplasty are not acceptable (e.g. revision of a previously implanted primary component, a humeral plate or a humeral nail).

In a reverse shoulder configuration, the Humeris Shoulder is indicated for primary or revision total shoulder athroplasty for the relief of pain and to improve function in patients with a massive and non-repairable rotator cuff tear.

The patient's joint must be anatomically suited to receive the selected implants and a functional deltoid muscle is necessary to use the device.

The Humeral Cup Stability and the Humeral Cup 135 / 145° Stability are components that are added to the Humelock II Reversible Shoulder System, the Humelock Reverse Shoulder and Humeris Shoulder, when used as a reverse shoulder replacement. The Humeral Cup and the Humeral Cup 135 / 145°. Mobility and Standard, were previously cleared for use in the U.S. in the Humelock II Reversible Shoulder System (K150488), and included as compatible components in the Humelock Reversed Shoulder System (K162455) and the Humeris Shoulder (K163669), when used for a reversed total shoulder construct. The 32mm Glenosphere and Cups were added to the reverse shoulder systems in K192206. These reverse total shoulder systems are used in patients with a non-functional rotator cuff and have an inverted articulation such that the ball of the articulation is on the glenoid side and the mating humeral cup is part of the humeral side of the construct, which includes either a cemented or cementless humeral stem. Depending on the humeral stem used, the humeral cup may be fixed to the humeral stem using a 135 / 145° Reverse Adapter. All mating components specific to each system are described in the respective cleared 510(k) submissions.

The predicate humeral cups, the Humeral Cup and the Humeral Cup 135 / 145°, are onepiece constructs consisting of a pre-assembled Ti-6Al-4V allov shell (ISO 5832-3) and a UHMWPE insert (ISO 5834-1 and ISO 5834-2). Both humeral cups are available in 32mm, 36mm and 40mm to articulate with the glenosphere of the same size (K150488) and come in heights of +3mm, +6mm, and +9mm.

The predicate humeral cups vary in depth providing different amounts of constraint and articulation. This submission is for the Stability variant of the Humelock Reverse Humeral Cup and 135 / 145° Humelock Reverse Humeral Cup and is a component added to the Humelock II Reversible Shoulder System (K150488), Humelock Reversed Shoulder System (K162455) and the Humeris Shoulder (K163669), when used for a reversed total shoulder construct.

The provided text is a 510(k) premarket notification for a medical device: Humeral Cup Stability & Humeral Cup 135/145° Stability. This document is a regulatory filing, not a study report. Therefore, it does not contain the detailed information typically found in a study proving a device meets acceptance criteria.

Specifically, the document states: "Clinical testing was not necessary to determine substantial equivalence of the Humeral Cup Stability to the predicate devices." This indicates that the FDA's substantial equivalence determination for this device was based on non-clinical testing and comparison to predicate devices, rather than a clinical study with acceptance criteria, human subjects, ground truth establishment, or multi-reader studies.

Therefore, I cannot provide the requested information, such as a table of acceptance criteria and reported device performance based on a human study, sample sizes for test sets, data provenance, number of experts, adjudication methods, or MRMC study details, because such a study was not conducted or presented in this regulatory filing.

The document focuses on demonstrating substantial equivalence to existing legally marketed devices (predicates) through:

• Comparison of Indications for Use: The new device's intended uses are compared to those of the predicate devices.
• Comparison of Fundamental Scientific Technology: The underlying principles and mechanisms are deemed similar.
• Material, Function, Manufacturing Processes, Shelf Life, Sterilization, Packaging, Instructions for Use, and Surgical Technique: These aspects are compared and shown to be similar or identical.
• Non-Clinical Testing: The document mentions mechanical testing to ASTM F2028-2017 and range of motion analysis, demonstrating that the device performs similarly to predicate devices and does not raise new questions of safety and effectiveness.

In summary, the provided document is a regulatory submission for premarket clearance via the 510(k) pathway, not a detailed report of a clinical study or a study designed to prove acceptance criteria through human performance data.

Hardware: The Materialise Glenoid Positioning System is intended to be used as a surgical instrument to assist in the intraoperative positioning of glenoid components used with total and reverse shoulder arthroplasty by referencing anatomic landmarks of the shoulder that are identifiable on preoperative CT-imaging scans.

Software: SurgiCase Shoulder Planner is intended to be used as a pre-surgical planner for simulation of surgical interventions for shoulder orthopedic surgery. The software is used to assist in the positioning of glenoid components. SurgiCase Shoulder Planner allows the surgeon to visualize, measure, reconstruct, annotate and edit pre-surgical plan data. The software leads to the generation of a surgery report along with a pre-surgical plan data file which can be used as input data to design the Materialise Glenoid Positioning Guide and Models.

Materialise Glenoid Positioning System is a patient-specific medical device that is designed to assist the surgeon in the placement of glenoid components.

This can be done by generating a pre-surgical plan or by generating a pre-surgical plan and manufacturing a patientspecific guide and models to transfer the plan to surgery. The device is a system composed of the following:

• a software component, branded as SurgiCase Shoulder Planner. This software is a planning tool used to ● generate a pre-surgical plan for a specific patient.
• a hardware component, branded as the Materialise Glenoid Positioning System™ Guide and Models, which is a patient specific guide and models that are based on a pre-surgical plan. This pre-surgical plan is generated using the software component. Patient-specific guide and models will be manufactured if the surgeon requests patient-specific guides to transfer the plan to surgery. The Materialise Glenoid Positioning System Guide is designed and manufactured to fit the anatomy of a specific patient. A bone model of the scapula is delivered with the Materialise Glenoid Positioning System Guide. A graft model can be delivered with the Materialise Glenoid Positioning System Guide.

The provided document (K190286) is a 510(k) Premarket Notification for the Materialise Glenoid Positioning System. This document describes the device, its intended use, and claims substantial equivalence to a predicate device (K172054). However, it does not contain the detailed acceptance criteria and the study results proving the device meets these criteria in the format requested.

The "Performance Data" section (page 5-6) explicitly states:
"Previous testing for biocompatibility, cleaning, debris, dimensional stability and packaging are applicable to the subject device and demonstrate substantial equivalence with the predicate device. Testing verified that the accuracy and performance of the system is adequate to perform as intended. The stability of the device placement, surgical technique, intended use and functional elements of the same as that of the predicate Materialise Glenoid Positioning System K172054 and previously cleared devices K170893, K1536559, and therefore previous cadaver testing on previously cleared devices K153602 and K131559 is considered applicable to the subject device."

This statement indicates that performance testing was conducted, and its results were deemed adequate. However, the details of those tests, including specific acceptance criteria, reported performance values, sample sizes, ground truth establishment, expert qualifications, and adjudication methods, are not present in this document. The document primarily relies on demonstrating substantial equivalence to previously cleared devices and states that "previous cadaver testing on previously cleared devices K153602 and K131559 is considered applicable to the subject device." This suggests that the detailed study results might be found in the 510(k) submissions for those predicate devices, rather than being explicitly laid out in this current submission.

Therefore, I cannot populate the table or provide specific details for most of your questions based solely on the text provided in K190286. The document focuses on regulatory justification for substantial equivalence, not a detailed scientific report of device performance trials.

The Materialise Glenoid Positioning System is intended to be used as a surgical instrument to assist in the intraoperative positioning of glenoid components used with total and reverse shoulder arthroplasty by referencing anatomic landmarks of the shoulder that are identifiable on preoperative CT-imaging scans.

The Materialise Glenoid Positioning System can be used in conjunction with Stryker's ReUnion RSA Reverse Shoulder System (K130895) and its respective components, with DJO's AltiVate Anatomic Shoulder (K162024), Encore Shoulder System (K051075), Turon™ to RSP Conversion Shell (K111629), Turon™ Shoulder System (K080402) and Reverse® Shoulder prosthesis (K092873) and their respective components, and Lima's SMR Shoulder System (K100858), SMR Reverse Shoulder System (K110598), SMR Modular Glenoid (K113254), SMR 3-Pegs Glenoid (K130642), SMR TT Metal Back Glenoid (K133349), SMR 40mm Glenosphere (K142139) and SMR Modular Glenoid (K143256) and their respective components and Depuy Synthes' GLOBAL® APG+ Shoulder System (K052472), the DELTA XTEND™ Reverse Shoulder System (K120174, K062250) and the GLOBAL® STEPTECH® APG Shoulder System (K092122) and their respective components.

The Materialise Glenoid Positioning System guide is single use only.

Materialise Glenoid Positioning Guides are patient-specific medical devices that are designed to assist the surgeon in the placement of glenoid components.

This can be done by generating a pre-surgical plan or by generating a pre-surgical plan and manufacturing patientspecific guides to transfer the plan to surgery. The device is a system composed of the following:

• a software component, branded as SurgiCase Planner. This software is a planning tool used to generate a pre-surgical plan for a specific patient.
• a hardware component, branded as the Materialise Glenoid Positioning System™ guide, which is a patient specific guide that is based on a pre-surgical plan. This pre-surgical plan is generated using the software component. Patient-specific guides will be manufactured if the surgeon requests patient-specific guides to transfer the plan to surgery. The guide is designed and manufactured to fit the anatomy of a specific patient.

The Materialise Glenoid Positioning Guides must only be used within the intended use of the compatible components.

The provided text describes the 510(k) premarket notification for the Materialise Glenoid Positioning System. It claims substantial equivalence to a predicate device (K153602) and mentions performance data from previous testing. However, it does not contain the detailed acceptance criteria or the study that directly proves the device meets specific acceptance criteria in terms of quantitative performance metrics.

The text states: "Previous testing for biocompatibility, cleaning, debris, dimensional stability and packaging are applicable to the subject device and demonstrate squivalence with the predicate device. Testing verified that the accuracy and performance of the system is adequate to perform as intended. The stability of the device placement, surgical technique, intended use and functional elements of the same as that of the predicate Materialise Glenoid Positioning System (K153602), and therefore previous cadaver testing on predicate device K153602 and previously cleared device K131559 (which is the predicate for K153602) is considered applicable to the subject device."

This indicates that some performance evaluation was done for the predicate devices, and that information is being leveraged for the current submission. However, the specific acceptance criteria (e.g., maximum allowable deviation, accuracy thresholds) and the results of a study against those criteria for the current device are not presented in this document.

Therefore, I cannot provide a complete answer to your request based solely on the provided text. I will, however, outline what information is available and explicitly state what is missing.

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

This information is not explicitly provided in the document. The text states: "Testing verified that the accuracy and performance of the system is adequate to perform as intended." This is a qualitative statement, not a quantitative table of acceptance criteria and performance against those criteria.

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

The document mentions "previous cadaver testing on predicate device K153602 and previously cleared device K131559".

• Sample size: Not specified.
• Data provenance: Cadaver testing. Country of origin not specified.
• Retrospective/Prospective: Not specified, but cadaver testing is typically prospective for the purpose of the study.

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 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

• MRMC study: Not mentioned. The device is a surgical instrument/guide, not typically an AI-driven image interpretation system that would involve "human readers" in the sense of diagnostic interpretation. It assists surgeons in positioning glenoid components based on preoperative planning.
• Effect size: Not applicable given the nature of the device and the lack of an MRMC study.

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

The device is a "patient specific guide that is based on a pre-surgical plan" and a "software component, branded as SurgiCase Planner. This software is a planning tool used to generate a pre-surgical plan for a specific patient." The "Materialise Glenoid Positioning System guides are patient specific templates which transfer the pre-operatively determined pin positioning to the patient intraoperatively, assisting the surgeon."

This indicates a human-in-the-loop process where a qualified surgeon inspects, fine-tunes, and approves the pre-surgical plan generated by the software. Therefore, a purely standalone algorithm-only performance as an output without human involvement is not the intended use model described. However, the accuracy of the output of the software (the surgical plan and subsequent guide design) would have been validated, which is essentially a standalone performance evaluation of the software component's mathematical and geometrical accuracy. The details of this validation are not in the document.

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

Given the "cadaver testing" and the nature of the device (positioning guide), the ground truth for measuring accuracy would likely be physical measurements against an intended planned position or anatomical landmark, potentially established by expert surgeons or precise measurement tools. However, the specific method of establishing this ground truth is not detailed in the document.

8. The sample size for the training set

The document describes premarket notification for a medical device that includes "a software component" for planning and "a hardware component" (patient-specific guide). It mentions "previous cadaver testing" which sounds more like a validation/testing stage rather than training for a machine learning model. If the software component involves machine learning or AI, the training set details are not provided. The text focuses on the device being "substantially equivalent" to a predicate, implying that much of the foundational validation comes from the predicate's testing.

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

As described in point 8, a "training set" in the context of machine learning is not explicitly mentioned, and thus how its ground truth was established is not provided. If the software uses algorithms that are not machine learning-based, then the concept of a training set as typically defined for AI may not apply. The emphasis is on the software generating a "pre-surgical plan" and its accuracy.

The ReUnion RSA Shoulder System is intended for primary, fracture, or revision total shoulder replacement. The patient's joint must have gross rotator cuff deficiency, a functional deltoid muscle and be anatomically and structurally suited to receive the selected implant(s).

• Painful, disabling joint disease of the shoulder resulting from: degenerative arthritis or rheumatoid arthritis
• Proximal humeral fracture
• Revision of previously failed shoulder joint replacement
• Glenoid Baseplate components are intended for cementless use with the addition of screw fixation. The humeral stem components are intended for both cemented and cementless use.

The ReUnion RSA Shoulder System is a system of components intended for total shoulder replacement in a reverse shoulder configuration. The system is comprised of a Humeral Cup, Humeral Insert, Glenoid Baseplate, Center Screw, Peripheral Screws and Glenosphere. The Humeral Cup with the Humeral Insert are attached to the humeral side of the joint via the ReUnion TSA Humeral Stem while the Glenosphere is implanted with the Glenoid Baseplate onto the glenoid side of the joint fixated with locking Center and Peripheral Screws. The ReUnion RSA Shoulder System components are indicated for primary reverse shoulder or revision reverse shoulder replacement procedures having gross rotator cuff deficiency.

The provided document is a 510(k) premarket notification for the ReUnion RSA Shoulder System, which is a medical device. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than providing detailed acceptance criteria and a standalone study proving the device meets those criteria in terms of clinical performance or algorithm accuracy.

Therefore, the requested information, which is typically associated with studies demonstrating the performance of diagnostic algorithms or standalone software, cannot be found in this document.

Specifically, the document states:

• "Clinical Testing: Clinical testing was not required for this submission." (Page 5)

This means there is no study presented in this 510(k) that evaluates the device's clinical performance against specific acceptance criteria in the manner requested. The document primarily focuses on non-clinical testing (e.g., fatigue strength, micromotion) to demonstrate substantial equivalence in design and materials to predicate devices.

As such, I cannot populate the table or answer the specific questions about acceptance criteria, reported performance, sample sizes for test sets, expert ground truth establishment, adjudication methods, MRMC studies, standalone performance, or training set details. This information is simply not part of a 510(k) for a physical implantable device like a shoulder system, especially when clinical testing is explicitly stated as not required.

The Titan™ Reverse Shoulder System is indicated for use in a grossly deficient rotator cuff joint with severe arthropathy or a previous failed joint replacement with a grossly deficient rotator cuff joint. 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 glenoid base plate is intended for cementless application with the addition of screws for fixation.
The humeral stem is indicated for cemented or uncemented use and the humeral body component is intended for cementless use.

The Integra TITAN Reverse Shoulder System is a modular shoulder prosthesis system. The humeral components consist of humeral stems, varying heights of reverse bodies, and humeral poly liners. The poly liners are available in varying thicknesses and constraints to achieve stability and offset of the glenohumeral joint. The variable length reverse bodies and proximally-filling shape are designed to accommodate the natural humeral geometry, providing stable fixation as well as proximal bone loading. The glenoid components are composed of a baseplate secured by a central compression screw and 4 peripheral screws, two of which can be locked. A glenosphere is attached to the baseplate via taper lock. Glenospheres are available in varying offsets and lateralizations.

The provided document describes the Integra TITAN Reverse Shoulder System, a medical device. The information details nonclinical testing performed to establish substantial equivalence to predicate devices, rather than a study proving the device meets specific acceptance criteria in a clinical or AI-assisted diagnostic context.

Therefore, the following information, as requested in the prompt, is not available in the provided text:

• A table of acceptance criteria and reported device performance (in a diagnostic context)
• Sample size used for the test set and data provenance (for diagnostic performance)
• Number of experts used to establish ground truth for the test set
• Qualifications of those experts
• Adjudication method
• If a multi reader multi case (MRMC) comparative effectiveness study was done
• Effect size of human readers improving with AI vs without AI assistance
• If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
• The type of ground truth used (expert consensus, pathology, outcomes data, etc.) for a diagnostic algorithm
• The sample size for the training set (for a diagnostic algorithm)
• How the ground truth for the training set was established (for a diagnostic algorithm)

However, I can extract information regarding the nonclinical performance testing that was conducted for the device. The document explicitly states: "Clinical performance data were not necessary to support substantial equivalence." This means no human clinical trials (as one might expect a diagnostic AI to undergo) were presented for this 510(k) submission.

Here's what can be extracted about the device's nonclinical performance:

Nonclinical Testing and Acceptance Criteria:

The Integra TITAN Reverse Shoulder System underwent several nonclinical performance tests to confirm its ability to perform under expected clinical conditions. The acceptance criteria for each test are implicitly met as the summary states the "System met all acceptance criteria" or "is acceptable" for each respective test.

Additional Notes:

• Sample Size (for nonclinical tests): The document does not specify the exact sample sizes (number of units tested) for each nonclinical test, but refers to "worst-case components or constructs" being tested.
• Data Provenance (for nonclinical tests): These are laboratory-based engineering tests, not clinical data from patients or a specific country.
• Ground Truth (for nonclinical tests): The ground truth for these tests is based on established engineering principles, biomechanical justification, industry standards (e.g., ASTM F2009-00(2011)), and FDA guidance documents.
• Training Set (for nonclinical tests): This concept does not apply to the nonclinical testing described. These are physical performance assessments against predefined engineering parameters.
