Important Note: The provided document is an FDA 510(k) clearance letter, which means the device has already been cleared. This letter summarizes the regulatory decision and mentions that studies were performed, but it does not contain the detailed study protocols, results, or data itself. Therefore, I will extract all available information and explicitly state when information is not present in this document.

Acceptance Criteria and Device Performance Study Summary

The acceptance criteria for this device are largely implied through the comparison to a predicate device and the successful completion of specified mechanical tests. The performance study focused on demonstrating substantial equivalence to the predicate device, particularly in mechanical properties relevant to its intended use as a bone fixation cerclage.

1. Table of Acceptance Criteria and Reported Device Performance

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

• Sample Size: The document does not specify the exact sample sizes (e.g., number of test specimens, number of cycles for fatigue) used for the mechanical testing. It mentions "chemical composition, creep test, tension static and fatigue tests."
• Data Provenance: The studies were conducted by the manufacturer, GM Dos Reis Industria e Comercio Ltda, which is based in Campinas, Brazil. The data is based on mechanical testing, not clinical data, and therefore is not characterized as retrospective or prospective in the usual clinical sense. It's laboratory-based performance data.

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

• For this type of mechanical device clearance, "ground truth" is established through engineering standards, validated test methodologies, and comparison to the known performance of predicate devices.
• The document does not mention the use of human experts (like radiologists) for "ground truth" establishment as would be common for AI/imaging device clearances. The "experts" involved would be engineering and quality control personnel at the manufacturer and potentially external testing laboratories, ensuring compliance with test methodologies.

4. Adjudication Method for the Test Set

• Since this is a mechanical device performance study, no explicit "adjudication method" in the sense of clinician consensus on medical images is applicable or mentioned. The "adjudication" is inherent in the adherence to established mechanical testing protocols and statistical analysis of the results to demonstrate equivalence to the predicate.

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

• No MRMC study was done. This type of study is specifically relevant for imaging devices or AI algorithms where human readers' performance is being evaluated or augmented. The Stitch Cerclage Suture System is a physical medical device, not an imaging or AI diagnosis system.
• The document explicitly states: "No clinical data were included in this submission."

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

• Not applicable. This concept pertains to AI algorithms. The Stitch Cerclage Suture System is a physical product and does not have an "algorithm-only" performance component.

7. Type of Ground Truth Used

• The "ground truth" for this device type is established through objective, quantifiable mechanical properties and material composition, compared against established industry standards (where available) or the performance of a legally marketed predicate device.
• Specifically, the study compared "chemical composition, creep test, tension static and fatigue tests" to information from a published article ("Cerclage Performance Analysis – a Biomechanical Comparison of Different Techniques and Materials", L. M. Hägerich, et al, Musculoskeletal Disorders (2022)) and to the predicate device.

8. Sample Size for the Training Set

• Not applicable / Not mentioned. This device is a physical product, not an AI algorithm. Therefore, there is no "training set" in the context of machine learning. The design and manufacturing process would involve internal validation and verification activities, but this is distinct from training an AI model.

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

• Not applicable. As there is no AI "training set," there is no ground truth established for one. The "ground truth" for the device's design and manufacturing is derived from engineering principles, relevant material standards (e.g., ASTM F899 for steel), and performance expectations set by the predicate device.

The GMReis Fibula Nail System is a system of locked intramedullary nails for osteosynthesis of fibular fractures. It has multiple lengths (110mm to 180mm) and diameters (3.0mm and 3.6mm). The arrangement of the holes in the intramedullary nails allows the surgeon to block the implant in different planes. The screws have a specific profile that reduces the risk of skin prominence and have threaded locking in the nail holes. GMReis Fibula Nail System are manufactured with titanium alloy, are for single use and the devices are provided non-sterile and must be properly cleaned and sterilized before use, according to the recommendations provided in the Instructions for Use.

The provided FDA 510(k) Clearance Letter for the "GMReis Fibula Nail System" (K250559) establishes substantial equivalence based on mechanical performance data, not clinical performance or AI/software-driven insights. Therefore, many of the requested points regarding acceptance criteria, study design, ground truth establishment, and expert involvement for an AI/software-based device cannot be extracted from this document.

The clearance is for a mechanical medical device (an intramedullary fixation rod), not a software or AI device. The type of acceptance criteria and study design are fundamentally different for a mechanical device versus a software/AI device.

However, I can extract the information relevant to this specific device's clearance process from the provided document:

4. Adjudication method for the test set

• Not Applicable. There is no "adjudication method" as understood in clinical studies with human observers. Mechanical testing results are compared against the accepted performance parameters of the ASTM standards and the predicate devices.

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 not an AI-assisted device, nor is it a diagnostic device that would involve human readers.

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

• Not Applicable. This is a physical medical implant, not an algorithm.

7. The type of ground truth used

• The "ground truth" for this medical device is adherence to established mechanical performance standards (ASTM F382 and F543) and factual data demonstrating substantial equivalence in material, design, and performance to legally marketed predicate devices.

8. The sample size for the training set

• Not Applicable. This is a physical medical device, not an AI model.

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

They are available on different sizes and shapes, according to the implantation site and the extension of the fracture. GMReis Ankle Plating System are for single use. The devices are provided non-sterile and must being properly cleaned and sterilized before use, according to the recommendations provided in the Instructions for Use.

This document, K242998, describes a 510(k) premarket notification for the "GMReis Ankle Plating System." This is a medical device, specifically bone plates and screws, and the submission aims to demonstrate its substantial equivalence to previously marketed predicate devices.

The request asks for information about the acceptance criteria and the study that proves the device meets them, specifically in the context of an AI/software-driven medical device. However, the provided document does NOT contain information about an AI/software component, nor does it detail acceptance criteria related to a diagnostic or analytical performance study typical of AI/software devices.

Instead, this document focuses on establishing substantial equivalence for a physical orthopedic implant through:

• Comparison of Technological Characteristics: Showing similarity in design, intended use, materials, manufacturing processes, and sterilization methods to predicate devices.
• Performance Data (Mechanical Testing): Demonstrating the physical performance of the plates and screws according to well-established ASTM standards for metallic bone fixation devices.

Therefore, I cannot provide the requested information regarding AI/software specific acceptance criteria, test set sample sizes, data provenance, expert ground truth, adjudication methods, MRMC studies, standalone AI performance, or training set details, as this information is not present in the provided document.

The "acceptance criteria" for this specific device (GMReis Ankle Plating System) are implicitly met by demonstrating that its mechanical performance is comparable to or better than the predicate devices, and that its materials and manufacturing processes are substantially equivalent.

Here's a breakdown of what can be extracted from the document, tailored to the spirit of your request but acknowledging the different nature of the device:

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

Note: The document states "Based on submitted testing data, the subject device is equivalent to the predicate devices." The specific numerical or statistical results of these mechanical tests that demonstrate equivalency are not provided in this summary, but the assertion is that the acceptance criteria for mechanical performance (i.e., meeting or exceeding predicate performance as per ASTM standards) were met.

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

• No information provided regarding sample sizes for human clinical data or diagnostic test sets, as this is a mechanical device primarily evaluated through engineering tests, not a diagnostic AI.
• Data Provenance: The mechanical testing data would typically be generated in a lab setting, presumably by the manufacturer (GM Dos Reis Industria e Comercio Ltda) from Brazil, as they are the submitter. The document does not specify the country of origin of the test data directly, but it would be expected to come from their internal or contracted testing facilities.

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)

• Not applicable. This pertains to establishing ground truth for diagnostic accuracy, which is not relevant for this physical device. Mechanical testing results are based on objective physical measurements against standards, not expert interpretation.

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

• Not applicable. No expert adjudication is described or required for mechanical testing of this nature.

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 device is a bone plate system, not an AI diagnostic tool. No MRMC study was conducted.

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

The EXPERT - Flexible Joint Fixation System is intended as an adjunct in fracture repair involving metaphyseal and periarticular bone fragments where screws are not indicated, and as an adjunct in external and intramedullary fixation systems involving plates and nails, with fracture braces and casting. The EXPERT - Flexible Joint Fixation System are intended to provide fixation during the healing process following:

EXPERT FAST - SYNDESMOSIS and EXPERT FAST DUAL:

Syndesmotic trauma, such as fixation of syndesmosis disruptions) in connection with Weber B and C ankle fractures.

EXPERT ACL and EXPERT ACL II:

Fixation of bone to bone or soft tissue to bone, and is intended as fixation posts, a distribution bridge, or for distributing suture tension over areas of ligament or tendon repair. Specifically, these models are offered for Anterior Cruciate Ligament (ACL) Repair.

EXPERT FAST - CORACOID PLATE and EXPERT FAST- AC:

Specifically, these models are intended to provide fixation during the healing process following a syndesmotic trauma, such as fixation of acromioclavicular separations due to coracoclavicular ligament disruptions.

The EXPERT - Flexible Joint Fixation System was designed for fixation, being used as a biomechanical structure to simulate a support pillar distributing the tensions in the suture wire or tape. The plates are manufactured in titanium alloy conforming to ASTM F136. The sutures are manufactured from UHMWPE. The devices are sold sterile and are single use. The EXPERT - Flexible Joint Fixation System is a line extension to the EXPERT - Joint Fixation System consisting of new models.

The provided text describes a medical device, the "EXPERT - Flexible Joint Fixation System," and its 510(k) summary for FDA clearance. However, the document does not contain information about acceptance criteria or a study that proves the device meets specific performance criteria in the way a clinical or algorithmic performance study would.

The document discusses equivalence to predicate devices based on "submitted testing data" but does not detail the nature of these tests, specific acceptance criteria, or the results. It mentions:

• Performance Data: "Based on submitted testing data, the proposed EXPERT - Flexible Joint Fixation System is equivalent to the Arthrex ACL TightRope (K100652) and TightRopeTM Acromioclavicular (K052776) predicate devices." (Page 6)
• Conclusion: "Any differences between the proposed device and the predicate device are considered minor and do not raise new or different questions concerning safety or effectiveness." (Page 6)

This refers to engineering testing or benchtop studies to demonstrate the mechanical equivalence or biocompatibility of the device's components to previously cleared predicate devices, rather than a study evaluating diagnostic or prognostic capabilities of an AI/ML algorithm.

Therefore, I cannot fulfill the request to provide a table of acceptance criteria and reported device performance related to a study proving the device meets these criteria in the context of AI/ML or clinical performance, nor can I provide information on sample sizes, ground truth establishment, expert qualifications, or MRMC studies for this particular device based on the provided text.

The information requested, such as sample size for test sets, data provenance, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, type of ground truth, training set size, and how training set ground truth was established, is not present in the provided FDA 510(k) summary for the EXPERT - Flexible Joint Fixation System. This is typical for a 510(k) for a physical medical device like a fixation system, which focuses on substantial equivalence to predicate devices through technical, material, and mechanical comparisons, rather than AI/ML algorithm performance.

Therefore, the sections of your request related to "acceptance criteria," "study that proves the device meets the acceptance criteria," "sample sizes used for the test set," "number of experts used to establish ground truth," "adjudication method," "MRMC comparative effectiveness study," "standalone performance," "type of ground truth," "sample size for training set," and "how ground truth for the training set was established" are not directly applicable in the context of this 510(k) submission for a metallic bone fixation appliance.

Instead, the submission relies on demonstrating substantial equivalence through a comparison of technological characteristics and non-clinical performance testing to recognized consensus standards.

Here's a breakdown of the relevant information from the provided text, addressing your questions where possible within the context of a 510(k) submission for this type of device:

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

The document does not present a table of acceptance criteria and reported device performance in the manner typically seen for clinical diagnostic studies or novel performance claims. For a 510(k) for a metallic bone fixation device, "acceptance criteria" are generally met by demonstrating that the device's mechanical properties are comparable to or meet the requirements of established ASTM standards, which are considered sufficient to ensure safety and effectiveness for its intended use, similar to predicate devices.

The "reported device performance" is indicated by its successful testing against these standards, implying it met the performance expectations set forth by those standards.

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

• Sample Size: The document does not specify the exact number of samples used for each mechanical test. This level of detail is typically found in the full test reports, not in the 510(k) summary. However, recognized consensus standards like ASTM F543 and F382 usually dictate the minimum number of samples required for robust testing.
• Data Provenance: The testing was "non-clinical" and performed against recognized consensus standards (ASTM F543, ASTM F382, USP <151>). This implies laboratory-based mechanical and biological (pyrogen) testing. The country of origin of the data is not explicitly stated, but the manufacturer is based in Brazil, suggesting the testing could have occurred there or by a certified lab elsewhere. The data is prospective in the sense that these tests were conducted specifically for this submission.

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

N/A. For mechanical and biological performance testing of a bone fixation device, "experts" in the sense of establishing clinical ground truth (like radiologists reading images) are not applicable. The "ground truth" for this device is its physical and material properties, assessed by engineering and laboratory methods against established standards.

The provided text describes a 510(k) submission for a medical device, the "Quick - Radius Disposable Set." The document primarily focuses on demonstrating substantial equivalence to existing predicate devices, rather than presenting a performance study against specific acceptance criteria for a novel device or an AI/algorithm-based diagnostic tool.

Therefore, the information required to populate the fields related to acceptance criteria, specific performance metrics, sample sizes for test sets, data provenance, expert ground truth establishment, adjudication methods, MRMC studies, standalone performance, and training set details for an AI/algorithm-based device is not present in the provided text.

The document states:

• "The proposed device is a line extension to the predicate device with new presentation forms." (Page 3, Section VI)
• "The proposed and predicate devices have the same basic design, intended use and biocompatibility profile." (Page 3, Section VI)
• "Difference between the proposed device and the predicate includes addition of a presentation form in a sterile condition." (Page 3, Section VI)
• "The subject Quick - Radius Disposable Set components possess the same technological characteristics as the predicate devices. These include: performance, shape and dimensions, material and manufacturing, sizes, biocompatibility and device usage." (Page 3, Section VII)
• "The EO sterilization has been validated to a sterility assurance level (SAL) of 10-6, according to ISO 11135" (Page 3, Section VII)
• "Any differences between the proposed device and the predicate device are considered minor and do not raise new or different questions concerning safety or effectiveness." (Page 3, Section VI and Page 4, Section VIII)

In conclusion, this submission is for a physical medical device (bone plates and screws set) seeking 510(k) clearance based on substantial equivalence to predicate devices, mainly through demonstrating equivalent design, materials, and a validated sterilization process. It does not involve software, AI, or diagnostic claims that would necessitate the types of performance studies and acceptance criteria typically associated with those technologies.

Therefore, I cannot fill in the requested table and answer the specific questions about "acceptance criteria" and "study that proves the device meets the acceptance criteria" in the context of an AI/algorithm, as the provided text does not contain such information. The "performance data" section in the document (Section VII) refers to the performance of the physical components (e.g., mechanical performance, biocompatibility) rather than diagnostic accuracy metrics.
