The provided text is a 510(k) premarket notification for a medical device (TDM Plate and Screw System). It describes the device, its indications for use, and a summary of performance testing to demonstrate substantial equivalence to predicate devices. However, it does NOT include acceptance criteria for a quantitative performance metric, nor does it describe a study that uses a test set against ground truth with experts and specific adjudication methods.

Instead, the performance data section mentions nonclinical tests and engineering analysis conducted in accordance with ASTM standards (F543-17 and F1264-16) to establish substantial equivalence. These standards are typically for mechanical properties and material compatibility, not for diagnostic or clinical performance against ground truth as would be evaluated for AI/ML-driven devices.

Therefore, I cannot fulfill your request for a table of acceptance criteria and reported device performance with the specific details requested (sample size for test set, data provenance, number of experts, adjudication method, MRMC study, standalone performance, type of ground truth, training set size, and ground truth establishment for training set). This type of information is generally found in submissions for devices that rely on algorithmic performance, often involving image analysis or diagnostic support, which is not the case for this bone fixation system.

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

1. Table of Acceptance Criteria and Reported Device Performance:

• Cannot provide. The document does not describe specific acceptance criteria (e.g., sensitivity, specificity, accuracy thresholds) or reported device performance in a clinical or diagnostic context. The "Performance Data" section refers to mechanical tests.

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

• Cannot provide. The document describes mechanical tests, not a study involving a test set of data (e.g., images, patient records).

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

• Not applicable. There is no "ground truth" in the clinical or diagnostic sense for this type of mechanical device evaluation. The "ground truth" for mechanical testing would be the physical properties measured in a lab.

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

• Not applicable. No such adjudication method is described as there isn't a test set with expert interpretation.

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 type of study is relevant for AI/ML diagnostic tools, not for a bone plate and screw system.

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

• Not applicable. This device is a physical implant, not an algorithm.

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

• Not applicable. The "ground truth" for mechanical testing would be direct measurements of physical properties (e.g., ultimate tensile strength, fatigue life), not expert consensus or pathology in a clinical context.

8. The sample size for the training set:

• Not applicable. There is no mention of a "training set" for this device, as it is not an AI/ML-driven product.

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

• Not applicable. As there is no training set, this question is not relevant.

Summary of available "Performance Data" from the document:

The "Performance Data" section states:
"The following testing was performed in accordance with the ASTM F543-17 and ASTM F1264-16:

• Static 4-Point Bending
• Axial Pullout
• Torsional
  The nonclinical tests and engineering analysis demonstrate that the TDM Plate and Screw Systems is as safe, as effective, and is substantially equivalent to the legally marketed predicate device."

This indicates that mechanical and material performance was evaluated, likely against the thresholds or expectations set by the referenced ASTM standards, which are considered the "acceptance criteria" for this type of device in terms of its physical integrity and performance. The study demonstrating this is the suite of nonclinical tests and engineering analysis performed according to those standards.

The provided text is related to an FDA 510(k) clearance for a medical device called the "TDM Screw System". It describes the device, its indications for use, and a summary of performance data. However, the document primarily focuses on regulatory approval based on substantial equivalence to a predicate device, rather than a clinical study evaluating the device's performance against specific acceptance criteria for an AI/algorithm-driven system.

Therefore, the information requested in your prompt regarding acceptance criteria, study design for AI/algorithm performance (e.g., test/training sets, expert ground truth, MRMC studies, standalone performance), and similar details are NOT present in the provided FDA 510(k) clearance document.

This document is for a physical medical device (metallic bone fixation fasteners), not an artificial intelligence or algorithmic diagnostic/decision-support system. The "Performance Data" section specifically mentions "The following testing was performed in accordance with the ASTM F543-17 and ASTM F1264-16: - Torsional - Pullout - 3-Point Bending". These are mechanical engineering tests for the physical properties of the screws, entirely unrelated to AI or software performance.

Therefore, I cannot populate the requested tables and information as the provided text does not contain the type of study data you are asking about for an AI/algorithm-driven device.

TDM Lumbar Interbody Fusion Cage System is indicated for intervertebral body fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2-S1, who have had six months of non-operative treatment. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies. These DDD patients may also have up to Grade 1 spondylolisthesis at the involved level(s). This device is to be used with autogenous bone graft. TDM Lumbar Interbody Fusion Cage System is to be used with supplemental fixation.

The TDM Lumbar Interbody Fusion Cage System (EVERGREEN PEEK PLIF Cage, LIME PEEK TLIF Cage, and PORTIA HYBRID TLIF cage) consists of intervertebral body fixation devices intended for use as an aid in spinal fixation. This system is fabricated and manufactured from PEEK as described by ASTM F2026. The Tantalum and Titanium marker used for this product is made to the voluntary standard of ASTM F560 and ASTM F136. The devices are available in a variety of different sizes and heights to match more closely the patient's anatomy. The ends of the implants have machined teeth which are designed to engage with the vertebral body end plates. The EVERGREEN PEEK PLIF Cages are to be implanted via posterior approach. Two PLIF PEEK cages are placed on each side of the interbody space (right and left). The LIME PEEK TLIF Cages and PORTIA HYBRID TLIF cages are dedicated to transforaminal approach. TLIF technique involves placing only one bone graft spacer in the middle of the interbody space, without retraction of the spinal nerves.

The provided document is a 510(k) summary for the TDM Lumbar Interbody Fusion Cage System, a medical device used in spinal fusion procedures. It outlines the device's intended use, technological characteristics, and a comparison to predicate devices, focusing on non-clinical performance testing.

Crucially, this document does not contain information about a study proving that an AI/software device meets acceptance criteria for diagnostic performance metrics (e.g., sensitivity, specificity, AUC). The performance data section explicitly states: "Non-clinical testing was performed to demonstrate that the subject TDM Lumbar Interbody Fusion Cage System is substantially equivalent to the predicate device. The following testing was performed in accordance with the ASTM F2077, and ASTM F2267: - Static Axial Compression - Dynamic Axial Compression - Static Torsion - Static Shear - Dynamic Shear - Subsidence."

These are mechanical and biocompatibility tests for a physical implantable device, not performance studies for an AI/software as a medical device (SaMD) that would have diagnostic accuracy metrics.

Therefore, I cannot fulfill your request to describe the acceptance criteria and the study proving the device meets those criteria for an AI/software device based on the provided text. The document is for a physical orthopedic implant.
