Device Description

The Aileron Interspinous Fixation System is a posterior, non-pedicle supplemental fixation device, intended for use in the non-cervical spine (T1-S1). Implants are manufactured from titanium alloy per ASTM F136 and are available in a range of sizes to suit the individual pathology and anatomical conditions of the patient.

AI/ML Overview

The provided text describes a medical device, the Aileron Interspinous Fixation System, and states that its substantial equivalency to predicate devices was demonstrated through performance data. However, it does not contain information about acceptance criteria or a study that specifically proves the device meets those criteria, as typically understood in the context of clinical or diagnostic performance. Instead, the "Performance Data" section details mechanical testing to demonstrate substantial equivalency.

Therefore, many of the requested fields cannot be filled from the provided text.

Here's a breakdown of what can be extracted and what cannot:

1. Table of acceptance criteria and reported device performance:

Acceptance Criteria (Mechanical Testing)	Reported Device Performance (Mechanical Testing)
Static Compression (per ASTM F1717)	Presented to demonstrate substantial equivalency
Dynamic Compression (per ASTM F1717)	Presented to demonstrate substantial equivalency
Static Axial Grip (per ASTM F1798)	Presented to demonstrate substantial equivalency

Note: The document states "subsequent engineering analysis was presented," implying the device met the requirements/comparisons set by these ASTM standards to demonstrate substantial equivalency with predicate devices. Specific quantitative acceptance criteria or raw performance values are not provided.

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

Sample size for test set: Not applicable or specified for mechanical testing. This typically refers to patient data, which is not part of this "Performance Data" section.
Data provenance: Not applicable. Mechanical testing is performed in a lab setting, not on patient data.

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

Not applicable. Ground truth, in this context, usually refers to clinical diagnostic accuracy, which is not assessed here. The "ground truth" for mechanical testing is adherence to ASTM standards and comparison to predicate devices, which would be evaluated by engineers.

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:

No, an MRMC study was not done. This study solely focuses on the mechanical performance of a spinal implant, not on AI-assisted diagnostic capabilities.

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

Not applicable. This is not an AI algorithm.

7. The type of ground truth used:

For the mechanical testing, the "ground truth" implicitly refers to the established standards of ASTM F1717 and ASTM F1798, and the performance characteristics of the predicate devices for comparison.

8. The sample size for the training set:

Not applicable. This is not an AI model requiring a training set.

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

Not applicable.
