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 document is a 510(k) summary for the Versalock Periprosthetic Femur Plates System - GMReis. This document outlines the regulatory submission for a medical device and, as such, does not contain information about a study that proves the device meets specific acceptance criteria in terms of clinical performance or diagnostic accuracy. Instead, it focuses on demonstrating substantial equivalence to a predicate device through non-clinical performance testing.

Therefore, many of the requested sections related to clinical studies, sample sizes for test and training sets, expert ground truth adjudication, MRMC studies, or standalone algorithm performance will not be available in this document.

Here's a breakdown of the information that can be extracted or inferred from the provided text:

1. Table of Acceptance Criteria and Reported Device Performance:

The document doesn't provide a table of explicit acceptance criteria with specific numerical targets. Instead, it states that performance was demonstrated through mechanical testing according to established ASTM standards. The "performance" in this context refers to the device's mechanical integrity and functionality, rather than a clinical outcome.

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

• Sample Size: Not applicable. This document describes mechanical testing of physical device components, not a study involving patient data or a "test set" in the context of AI/diagnostic device performance. The sample sizes would refer to the number of plates, screws, and cables tested in the lab. This specific number is not provided, though it would typically be defined by the ASTM standards.
• Data Provenance: Not applicable. The data comes from internal mechanical testing, not patient data from a specific country or collected retrospectively/prospectively.

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

• Not applicable. Ground truth as typically defined for diagnostic AI/clinical studies (e.g., expert consensus on images, pathology results) is not relevant to this type of device submission. The "ground truth" here is the adherence to mechanical engineering standards, which is determined by test procedures and measurement against those standards.

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

• Not applicable for the reasons stated above.

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. This is not a diagnostic AI device, and therefore, an MRMC study is not relevant or mentioned.

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

• No. This is a physical medical implant device, not an algorithm.

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

• For the non-clinical performance (mechanical testing), the "ground truth" is adherence to established engineering standards (ASTM F382, ASTM F543, ASTM F2180) and a risk assessment based on biocompatibility standards (ISO 10993-1).
• For the substantial equivalence claim, the "ground truth" is the characteristics of the predicate device, which the subject device is compared against.

8. The sample size for the training set:

• Not applicable. There is no training set mentioned as this is not an AI/machine learning device.

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

• Not applicable. There is no training set.
