This document is a 510(k) premarket notification from the FDA for a medical device called the Endoskeleton™ Interbody System. It's a clearance letter, not a study report. Therefore, it does not contain the detailed acceptance criteria or a study that proves the device meets specific acceptance criteria in the way you've outlined.

The FDA 510(k) process is primarily focused on demonstrating "substantial equivalence" to a legally marketed predicate device, rather than proving safety and effectiveness through new clinical trials against predefined acceptance criteria like a PMA (Premarket Approval) application would.

Here's what can be extracted from the document based on your request, and where information is inherently missing due to the nature of a 510(k) clearance:

1. Table of acceptance criteria and the reported device performance:

This information is not provided in the document. The document states "no new mechanical testing was required for this Submission" because "There is no change to the Endoskeleton™ Interbody System product families' design, manufacturing, materials, nor intended use." This implies that performance has been demonstrated through substantial equivalence to predicate devices, rather than new testing against defined criteria for this specific submission.

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

No new test set or data provenance is detailed. The substantial equivalence argument relies on the prior clearance of predicate devices.

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):

This information is not applicable/provided as no new test set requiring expert ground truth establishment is described.

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

This information is not applicable/provided.

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:

This information is not applicable/provided. The device is an intervertebral body fusion system, not an AI diagnostic tool.

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

This information is not applicable/provided. This is a physical implant device, not a standalone algorithm.

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

This information is not applicable/provided for this 510(k). The regulatory clearance is based on substantial equivalence to predicate devices, which would have had their own "ground truth" (e.g., clinical outcomes, mechanical testing) established during their initial approval/clearance.

8. The sample size for the training set:

This information is not applicable/provided as this is a physical medical device, not an AI/ML algorithm that requires a training set.

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

This information is not applicable/provided as this is a physical medical device, not an AI/ML algorithm.

Summary of what the document does provide regarding performance and equivalence:

• Mechanical Testing: According to the document, "no new mechanical testing was required for this Submission" because there were no changes to the product families' design, manufacturing, materials, or intended use. This means its mechanical performance is considered substantially equivalent to the predicate devices.

• Biocompatibility: The implants are made from materials (ASTM F136 Ti 6Al-4V ELI titanium alloy and ASTM F3001 Ti 6Al-4V ELI titanium alloy) that have "a long history of safe and effective use identical to predicate devices and biocompatibility testing is not required."

• Substantial Equivalence: The primary "proof" of meeting acceptance criteria for this 510(k) is the demonstration of substantial equivalence to three predicate devices:

  • EIT Cellular Titanium® Cages- K201605 (S.E. 07/15/2020)
  • Endoskeleton™ Interbody Systems- K192018 (S.E. 08/13/2019)
  • NuVasive Interbody Systems K203201 (S.E. 01/12/2021)

  The substantial equivalence is based on having the same intended use, fundamental scientific technology, material, sizing, and sterilization method as the predicate devices. Modifications described include identification of nanoLOCK™ Surface Technology and expansion/modification of indications based on the cleared indications of the predicate devices.

In conclusion, this document is a regulatory clearance based on substantial equivalence, not a detailed study report demonstrating performance against specific acceptance criteria for a new device.

The Endoskeleton® TCS Interbody Fusion Device is an anterior cervical intervertebral body fusion device indicated for use in skeletally mature patients with degenerative disc disease (DDD) (defined as pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies) at one disc level from C2 to T1. Patients should have received 6 weeks of non-operative treatment with the device. The device is indicated to be used with autograft bone or allograft bone comprised of cancellous bone. The device is a stand-alone system when used with Endoskeleton® TCS Interbody Fusion Device integrated screws and when used without the integrated screws it requires additional supplemental fixation cleared for the cervical spine.

The Endoskeleton® TCS Interbody Fusion Device (IBD) implants are available in a variety of sizes with a variety of lordotic angles, to accommodate patient anatomy. Endoskeleton® TCS IBD implants are intended for treatment in Cervical Interbody Fusion used in single placement treatment placed across the disc space, and are designed with a large hollow region in the center to house bone graft material. The superior and inferior surfaces have been acid etched through a previously cleared process called nanoLOCK™ (MMN™) to improve fixation to the adjacent bone.

The purpose of this special 510(k) submission is to add a plate to the Endoskeleton® TCS System. The ENDOSKELETON® TCS Plate Device (Plate) is compatible with the ENDOSKELETON® TCS Interbody Fusion Device product family. The design incorporates a locking screw to secure the Interbody Fusion Device and is engaged after the placed on the anterior face of the ENDOSKELETON® TCS Interbody Fusion Device to resist the integrated screws from backing out. The system includes a holding feature on the Plate to mate with the inserter to facilitate placement onto the ENDOSKELETON® TCS Interbody Fusion Device implant. Use of this plate is an enhancement to the existing Endoskeleton® TCS system and, as such, is optional with the Endoskeleton® TCS Interbody Fusion Device and does not qualify as supplemental fixation. The subject plate does not include nanoLOCK® (MMN™) surface treatment, as it does not interface with the bone.

The construct is a stand-alone system when used with Endoskeleton® TCS integrated screws and when used without the integrated screws it requires additional supplemental fixation cleared in the cervical spine.

All implantable components are manufactured from medical grade titanium alloy (Ti-6Al-4V-EL)) and may be provided either sterile. The subject Endoskeleton® TCS Plate is only provided sterile by gamma irradiation.

I am sorry, but based on the provided text, there is no information about acceptance criteria, device performance in relation to those criteria, or details regarding a study that proves the device meets specific acceptance criteria.

The document is a 510(k) premarket notification summary for the Endoskeleton® TCS Interbody Fusion Device. It focuses on demonstrating substantial equivalence to previously cleared predicate devices for regulatory clearance, rather than presenting a detailed study evaluating specific performance metrics against pre-defined acceptance criteria.

The "Performance Testing" section states: "Performance bench testing, including locking plate resistance to screw push-out and retention force of the plate holder, was performed to demonstrate substantial equivalence." However, it does not provide:

• A table of acceptance criteria and reported device performance.
• Details about sample sizes, data provenance, or ground truth establishment.
• Information about expert involvement or adjudication methods.
• Any mention of a multi-reader multi-case (MRMC) study or standalone algorithm performance, as this device is a physical interbody fusion device, not an AI or imaging device.

The Endoskeleton® TCS System is an anterior cervical intervertebral body fusion device indicated for use in skeletally mature patients with degenerative disc disease (DDD) (defined as neck pain with degeneration of the disc confirmed by history and radiographic studies) at one disc level from C2 to T1. Patients should have received 6 weeks of non-operative treatment pror to treatment with the device is indicated to be used with autograft bone. The device is a stand-alone system when used with Endoskeleton® TCS integrated screws and when used without the integrated screws it requires additional supplemental fixation cleared in the cervical spine.

The Endoskeleton® TCS Interbody Fusion Device (IBD) implants are available in a variety of sizes with a variety of lordotic angles, to accommodate patient anatomy. Endoskeleton® TCS IBD implants are intended for treatment in Cervical Interbody Fusion used in single placement treatment placed across the disc space, and are designed with a large hollow region in the center to house bone graft material. The superior and inferior surfaces are acid etched to improve fixation to the adjacent bone. The device is a stand-alone system when used with Endoskeleton® TCS integrated screws and when used without the integrated screws it requires additional supplemental fixation cleared in the cervical spine. All implantable components are manufactured from medical grade titanium alloy (Ti-6AI-4V-ELI). The primary modification being made in this submission is that the hex size on the screws is being changed from T6 to T8 and as a result the heights now range from 13 – 21.35mm. As a result, there was a small change to the overall length of the screws and a change to the instruments associated with the hex update.

This FDA 510(k) summary for the Endoskeleton® TCS Interbody Fusion Device (K151596) deals with a minor modification to an already cleared device (predicate device K142940). Therefore, the provided text does not contain the detailed information typically found in a new device's acceptance criteria and study report.

Specifically, this document describes a modification to the hex size of the screws used with the device and a slight change in the screw heights. It argues for substantial equivalence to the predicate device without conducting new performance studies for these modifications, relying instead on an "engineering rationale."

Therefore, for this particular submission (K151596), many of the requested sections about acceptance criteria and study details cannot be fully answered. This document provides an engineering rationale for why these minor changes do not impact safety and effectiveness, rather than reporting on new performance studies.

Here's a breakdown based on the provided text, indicating where information is present and where it is explicitly stated as not applicable due to the nature of this 510(k) submission:

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

The document does not provide a table of acceptance criteria or new reported device performance for K151596 because it's a modification to an already cleared device. The manufacturer states that the modifications (hex size and screw height) do not impact the overall function, and thus, no new performance testing was deemed necessary. The "reported device performance" is essentially that the modified device performs equivalently to the predicate device based on engineering rationale.

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

Not applicable. No new test set or data provenance is mentioned for K151596 as no new performance studies were conducted for this specific modification. The submission relies on the prior clearance (K142940) for such information.

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. No new test set requiring expert ground truth establishment was created for K151596 since no new performance studies were conducted.

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

Not applicable. No adjudication method is mentioned for K151596 as no new test set needing adjudication was generated.

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 an interbody fusion device, which is a physical implant, not an AI-assisted diagnostic or therapeutic tool. Therefore, MRMC studies are not relevant to this type of medical device.

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

Not applicable. This is a physical implant, not an algorithm, so standalone algorithm performance is not relevant.

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

Not applicable. No new ground truth was established for K151596 as no new performance studies were conducted. The substantial equivalence argument rests on the predicate device's prior approval.

8. The sample size for the training set

Not applicable. This is a physical implant, not a machine learning model, so there is no training set.

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

Not applicable. As above, there is no training set or ground truth for a training set for this physical medical device.

Not applicable. This device underwent mechanical testing, not a study requiring adjudication of clinical data.

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

Not applicable. This document describes the 510(k) submission for a medical device (intervertebral body fusion device) primarily based on mechanical performance and substantial equivalence to predicate devices, not an AI-powered diagnostic or assistive tool. Therefore, an MRMC comparative effectiveness study with human readers and AI assistance is not relevant.

6. Standalone (Algorithm Only) Performance Study

Not applicable. As noted above, this is a physical medical device, not an algorithm or AI model.

7. Type of Ground Truth Used

The "ground truth" for the mechanical performance testing was based on the results obtained from testing the substantially equivalent predicate devices according to established ASTM standards (ASTM F2077 and ASTM F2267). The subject device's performance was then compared to these predicate device results to demonstrate substantial equivalence.

8. Sample Size for the Training Set

Not applicable. This is a physical medical device undergoing mechanical testing, not an AI model that requires a training set.

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

Not applicable. As this is not an AI model, there is no training set or associated ground truth establishment.
