The Genostis Osteosynthesis System comprises of fracture fixation plates, corresponding screws and required surgical instruments. Different shapes and sizes are available to accommodate for different anatomical regions and locations of fractures. The plate screw interface is either locking, non-locking or, for some plates, realized by a combination hole offering both options (locking and non-locking).

All plates and screws are made of titanium alloy (Ti 6Al 4V ELI) according to ASTM F136 and ISO 5832-3.

The implants of the Genostis Osteosynthesis System are sterilized by radiation and are delivered sterile.

The provided FDA 510(k) clearance letter for the Genostis Osteosynthesis System does not describe a study involving an AI/software device or human readers. Instead, it describes a traditional medical device (bone fixation plates and screws) and primarily references non-clinical (biomechanical and biocompatibility) testing to demonstrate substantial equivalence to predicate devices.

Therefore, many of the requested criteria related to AI/software performance, human reader studies, and ground truth establishment in a diagnostic context are not applicable to this document.

However, I can extract and structure the information that is relevant to the device's acceptance criteria based on the provided text, particularly concerning non-clinical testing.

Here's the breakdown based on the information available:

Acceptance Criteria and Study for Genostis Osteosynthesis System

The Genostis Osteosynthesis System is a traditional medical device (bone fixation plates and screws), not an AI/software diagnostic device. As such, the "acceptance criteria" and "study" proving it meets them are primarily based on non-clinical engineering and biological tests, not AI performance metrics or human-in-the-loop diagnostic studies.

1. Table of Acceptance Criteria and Reported Device Performance

Note: The document states "All results were satisfactory" for all tests, indicating the device met the pre-defined acceptance criteria for each test.

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

• Sample Size: The document does not specify the exact number of units or samples used for each biomechanical or biocompatibility test. It generally states that testing was "performed" and "conducted on final sterile product."
• Data Provenance: Not explicitly stated as "country of origin," but testing would be performed in a controlled laboratory environment. The tests are non-clinical (biomechanical and biocompatibility), not data from patients. The study is by nature prospective in that new manufactured devices were tested to meet the standards, not a retrospective analysis of existing data.

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

• Not Applicable. This is a medical device (hardware) clearance, not an AI/software diagnostic device that requires expert ground truth for interpretation of medical images or other diagnostic data. The "ground truth" here is the adherence to established engineering and biocompatibility standards.

4. Adjudication Method for the Test Set

• Not Applicable. As this is non-clinical mechanical and biocompatibility testing, there is no "adjudication" in the sense of reconciling expert opinions on diagnostic findings. The results are quantitative and objective measurements against established standard thresholds.

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

• Not Applicable. MRMC studies are for evaluating clinical interpretation of diagnostic results, typically with AI assistance. This device is a physical implant, not a diagnostic tool or AI.

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

• Not Applicable. This pertains to AI algorithm performance. The device is a bone fixation system and does not rely on an algorithm for its primary function.

7. The Type of Ground Truth Used

• Pre-defined Standards and Controls: The "ground truth" for this device's performance is established by well-defined, internationally recognized (ISO) and American (ASTM) standards for material properties, mechanical strength, and biocompatibility. The device must perform within the specified parameters of these standards. For example, screws must meet certain torque resistance (ASTM F543), and plates must meet specific load-sharing characteristics (ASTM F382).

8. The Sample Size for the Training Set

• Not Applicable. This device does not involve a "training set" in the context of machine learning or AI.

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

• Not Applicable. There is no "training set" for this type of medical device clearance. The design and manufacturing processes are established based on engineering principles and existing predicate device designs, with performance validated against the standards mentioned above.

The provided text is a 510(k) summary for the DePuy Synthes VOLT Mini Fragment Plating System and VOLT Small Fragment Plating System. This document describes the device, its indications for use, and a comparison to predicate devices, focusing on non-clinical performance testing (mechanical and engineering analyses) to demonstrate substantial equivalence.

Crucially, this document explicitly states: "Clinical testing was not necessary for the determination of substantial equivalence."

Therefore, the requested information regarding acceptance criteria, study details (sample size, data provenance, expert ground truth, adjudication, MRMC, standalone performance, training set details), which are typically found in clinical performance studies validating AI/ML-based medical devices, is not applicable to this submission.

This 510(k) clearance is based on the devices being "substantially equivalent" to existing predicate devices, primarily demonstrated through non-clinical performance testing (mechanical simulations and analyses), rather than clinical trials or studies involving human data and AI algorithm performance.

Therefore, I cannot provide the requested information as it is not present in the provided text. The device in question is a physical orthopedic implant, not an AI/ML software device that would require such performance evaluations.

These devices are made of commercially pure titanium and titanium alloy with Type III anodization, and are available in a variety of sizes and diameters, as well as locking and non-locking types.

The provided document is a 510(k) premarket notification for the Stryker VariAx 2 System and VariAx 2 Mini Fragment System. This type of submission relies on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving safety and effectiveness through clinical trials with specific acceptance criteria as might be seen for novel devices.

Therefore, the document does not contain the detailed information requested regarding acceptance criteria and a study proving the device meets them in the way this request envisions for a software or AI-based medical device.

However, I can extract the information provided about the non-clinical testing performed to demonstrate substantial equivalence, which serves a similar purpose in the context of a 510(k) submission.

Here's the breakdown of what is available based on the provided text:

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

The document does not specify quantitative acceptance criteria. Instead, it states that "The aforementioned testing demonstrated that the VariAx 2 Mini Fragment System and the VariAx 2 System are substantially equivalent to the predicate devices." This implies that the performance of the new devices in these tests was comparable to or better than the predicate devices, satisfying the FDA's requirement for substantial equivalence for mechanical properties.

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 does not specify the sample sizes (e.g., number of screws, plates tested) for the non-clinical mechanical tests. It also does not provide information on data provenance as these are physical device tests, not data-driven studies.

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 was a non-clinical, mechanical testing study of physical medical devices, not a study involving expert interpretation of data.

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

Not applicable. This was a non-clinical, mechanical testing study.

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 was a non-clinical, mechanical testing study, not a human reader study involving AI.

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

Not applicable. This was a non-clinical, mechanical testing study.

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

For the mechanical tests, the "ground truth" or reference for comparison was the performance of the identified predicate devices (Smith & Nephew Variable-Angle Locking Mini-Fragment Plating System (K132886) and Synthes (USA) Modular Mini Fragment LCP System (K063049) for the Mini Fragment System, and VariAx 2 System (K180500) for the VariAx 2 System). The tests measured physical properties and compared them against known standards or the predicate's performance. For MRI safety, the ground truth would be established by industry standards or FDA guidance for MR compatibility.

8. The sample size for the training set

Not applicable. This was a non-clinical, mechanical testing study, not an AI or machine learning study requiring a training set.

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

Not applicable. This was a non-clinical, mechanical testing study.

Summary of the Study:

The study referenced in the 510(k) submission is a non-clinical mechanical testing study. Its purpose was to demonstrate substantial equivalence of the VariAx 2 Mini Fragment System and the VariAx 2 System to their respective predicate devices.

Tests Performed:

• Torsion
• Insertion Torque
• Pull-out
• Four-point bending
• MRI assessments (magnetically-induced displacement force, magnetically-induced torque, RF-induced heating, and image artifacts)

Conclusion of the Study:

The non-clinical testing "demonstrated that the VariAx 2 Mini Fragment System and the VariAx 2 System are substantially equivalent to the predicate devices." Additionally, the devices were found to be MR conditional. Clinical testing was not required for this submission.

This is a 510(k) premarket notification for a medical device, specifically the Synthes 2.7/3.5mm Variable Angle LCP Ankle Trauma System - Anterolateral Distal Tibia Plates.

This type of submission is for demonstrating substantial equivalence to a legally marketed predicate device, rather than providing clinical safety and efficacy data. Therefore, the information you're requesting regarding acceptance criteria, study details, expert review, and ground truth establishment, which are typical for studies validating AI/ML diagnostic devices, are not present in this document. This submission focuses on engineering analysis and comparison to existing, already approved devices.

Here's why your specific questions cannot be answered from this document:

• This is not an AI/ML device. The device is a physical bone fixation system (plates and screws). Therefore, concepts like "device performance" in terms of classification metrics (sensitivity, specificity), "test sets," "training sets," "ground truth" (in the context of expert consensus or pathology for diagnostic accuracy), or "MRMC studies" are not applicable.
• 510(k) is about substantial equivalence. The primary way this device met its acceptance criteria was by demonstrating that it is "at least as strong as" and has similar indications, design, materials, and performance characteristics as previously cleared predicate devices.

However, I can extract information related to the device and its "proof" of meeting requirements based on the document provided:

1. Table of Acceptance Criteria and Reported Device Performance:

Regarding the other points, as explained, they are not applicable or not provided in this 510(k) submission for a physical implantable device:

2. Sample size used for the test set and the data provenance: Not applicable. Performance was demonstrated through engineering analysis and fatigue testing, not a "test set" of clinical data.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. No "ground truth" was established by experts for a diagnostic assessment.
4. Adjudication method for the test set: Not applicable.
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.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable. This is not an algorithm.
7. The type of ground truth used: Not applicable. The "ground truth" equivalent here would be established engineering standards for strength and fatigue, against which the device was tested.
8. The sample size for the training set: Not applicable. No "training set" for an algorithm.
9. How the ground truth for the training set was established: Not applicable.

In summary, this 510(k) relied on demonstrating substantial equivalence through a comparison of indications, design, materials, and engineering performance (mechanical strength) to already approved predicate devices. It did not involve clinical studies or expert evaluations of diagnostic accuracy as would be the case for AI/ML diagnostic software.
