Based on the provided text describing the VADER® Pedicle System and VADER®one Pedicle System, it's clear this document is an FDA 510(k) clearance letter for a medical device. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving direct clinical effectiveness of a new technology.

Therefore, the document does not contain the kind of information requested regarding acceptance criteria, performance studies involving AI, human readers, ground truth establishment, or sample sizes related to AI/algorithm development. The performance testing mentioned is confined to "Bench testing consisting of static axial gripping capacity testing and static torque gripping capacity per ASTM 1798 and dynamic compression bending per ASTM F1717 was successfully completed," which are mechanical performance tests, not clinical or AI-related studies.

In summary:

• There is no mention of acceptance criteria and reported device performance related to an AI/software component. The "acceptance criteria" discussed implicitly by the FDA in a 510(k) context are those for establishing substantial equivalence to a predicate, primarily through material, design, and mechanical performance comparisons.
• There is no data regarding a "test set" for an AI or imaging algorithm. The "study" described is bench testing of the pedicle system's mechanical properties.
• No experts, ground truth, or adjudication methods are discussed in the context of clinical AI performance.
• No MRMC comparative effectiveness study or standalone algorithm performance is described.
• The type of ground truth used is not applicable as this is not an AI/imaging device. The "ground truth" for this device would be its physical properties meeting standards and its successful mechanical performance.
• No training set for an AI algorithm is mentioned.
• Ground truth for a training set is not applicable.

This document pertains to the market clearance of a pedicle screw system, primarily based on its mechanical performance and substantial equivalence to existing devices, not on the performance of an AI or imaging diagnostic algorithm.

The icotec Anterior Cervical Plate System is intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the cervical spine (C2-T1) in whom life expectancy is of insufficient duration to permit achievement of fusion.

When used with the icotec Cervical Cage or the KONG®-C VBR System, the icotec Anterior Cervical Plate System is intended to stabilize the cervical (from C2 to T1) spine as an adjunct to fusion in patients with spinal infection (e.g., spondylodiscitis, osteomyelitis) and spinal instability due to infection, surgical debridement, or decompression.

The icotec Anterior Cervical Plate System consists of plates and screws intended for use in anterior cervical fixation from C2 to T1. The system is developed to allow for conventional ventral approaches to the cervical spine. The devices are manufactured from high strength carbon fiber reinforced polyetheretherketone (Carbon/PEEK, BlackArmor®) and incorporate tantalum markers per ASTM F560.

The icotec Anterior Cervical Plate System is available in various plate lengths and with selftapping screws for the specific adaption to the patient's anatomy. The icotec Anterior Cervical Plates are 18 mm in width and come as 1- to 4-segmental implants with lengths ranging from 21 up to 94 mm. The plates are precontoured to fit patient anatomy. The screw holes in the plates are conical and threaded.

The icotec Anterior Cervical Plate System self-tapping screws are available in diameters of 4.0 and 4.25 mm with lengths of 13 and 15 mm. The fully threaded bone screws have threaded conical heads to firmly lock into the plate. The conical threaded screw heads are designed to block pullout while screw angulation in the cranial direction prevents screws from penetrating through the lower end plate of the vertebral body.

This document describes the regulatory clearance (K233215) for the icotec Anterior Cervical Plate System. The information provided focuses on the device's technical specifications and the basis for its substantial equivalence to a predicate device, rather than detailed performance study results against specific, quantifiable acceptance criteria.

The provided text does not contain a detailed study with specific acceptance criteria and reported device performance in the format of a table as requested. Instead, it presents a summary of non-clinical and clinical data supporting substantial equivalence.

Based on the provided text, here's an attempt to extract and infer the requested information, noting limitations due to the nature of the available document:

1. Table of Acceptance Criteria and Reported Device Performance

The FDA clearance letter for a 510(k) submission typically does not present performance data in a detailed table against pre-defined acceptance criteria, especially for a device seeking substantial equivalence based on prior clinical data without a de novo clinical trial. Instead, it refers to a summary of performance testing and clinical data that broadly supported substantial equivalence.

The document explicitly states: "However, the provided clinical data did not support that the specific material or unique technological characteristics of the subject device components provides additional benefit relative to other anterior cervical plate devices for the indications for use related to infection." This suggests that while equivalence was shown, superiority or additional benefit for specific aspects (like infection) was not demonstrated. |
| Substantial Equivalence | The device was demonstrated to be substantially equivalent to the predicate device (K201587) with respect to indications for use, intended use, design, and performance, based on non-clinical testing data and clinical data. The subject and predicate devices are stated to have similar technological characteristics, be made of similar materials, and are packaged/sterilized by identical methods. The conclusion is that the device is substantially equivalent. |

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

• Sample Size for Test Set: Not specified in the provided text. The document refers to "clinical data provided" but does not detail the size or nature of this dataset in terms of individual patients or cases used for the "test set" (if a distinct test set was even explicitly defined in the context of this 510(k) submission).
• Data Provenance: Not specified. The document does not mention the country of origin of the data or whether the studies were retrospective or prospective.

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

• This information is not available in the provided document. The clearance letter mentions "clinical data" but does not detail how ground truth was established for any specific test set, or the number and qualifications of experts involved in such a process.

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

• This information is not available in the provided document.

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 document describes a spinal implant device (Anterior Cervical Plate System), not an AI/software device that would involve human readers or AI assistance in interpretation. Therefore, an MRMC study related to AI assistance would not be applicable in this context.

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

• This document concerns a physical medical device, not an algorithm. Therefore, "standalone algorithm performance" is not applicable.

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

• For a spinal implant device seeking 510(k) clearance based on substantial equivalence, the "ground truth" would typically refer to established clinical safety and effectiveness from the predicate device and the clinical data supporting the subject device's performance. This would involve "outcomes data" and potentially clinical assessments, but the specific methodology (e.g., expert consensus on outcomes) is not detailed here. The document states "clinical data provided supports a substantially equivalent safety and effectiveness profile."

8. The sample size for the training set:

• This concept of "training set" is relevant for AI or machine learning models. This document is about a physical medical device. Therefore, a "training set" in that context is not applicable.

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

• As above, the concept of a "training set" for ground truth establishment is not applicable to this type of device.

KONG®-TL VBR System: The KONG®-TL VBR System is a vertebral body replacement system for anterior stabilization of the thoracic and lumbar spine. This device serves as a replacement for vertebral bodies in tumorous and traumatic diseases which lead to instabilities in the anterior support or compression of neural structures or diseases that make an infection repair necessary. The KONG®-TL VBR System is intended for use with an additional dorsal or anterolateral fixation system (e.g., icotec Pedicle System). The KONG®-TL VBR System is a modular design featuring an expandable body, extensions, and end plates with various heights, widths, and angles. The system consists of expandable body structures that range in height from 19 to 96 mm, have a diameter of 19 mm and surface treads/spikes on its cranial and caudal end plate surfaces that serve to guide and anchor the implant. The system also consists of rectangular and round end plate configurations. The end plate round configuration has a geometry that ranges from 0°, 4°, 8° and 12° and size that ranges from 26 to 43 mm. The end plate rectangular configuration has geometry that ranges from 0°, 4°, 8° and 12° and size that ranges from 33 to 52 mm. The end plates are locked with a screw onto the main body. The tread surfaces and spikes help to improve primary fixation stability of the end plates. The large contact surface of the end plates reduces the risk of migration. The screw for fixation of the end plates to the body has a length of 6 mm and a thread size of M8.

The KONG®-TL VBR System is made of BlackArmor® material, a carbon fiber reinforced polyetheretherketone (Carbon/PEEK) composite. The BlackArmor® material is a combination of continuous, high strength carbon fiberreinforced PEEK and icotec's composite flow molding (CFM) process. The result is a non-metallic implant component with an interwoven 3D fiber architecture that provides strength and endurance. BlackArmor® is radiolucent in all diagnostic imaging modes (MRI, CT and X-ray) and will therefore not create imaging artifacts. Embedded tantalum markers (per ASTM F560) ensure the required radiologic visibility of the implant during surgery and follow-up. The KONG®-TL VBR System incorporates a rough cp-titanium coating (per ASTM F1580), designed to improve direct bone apposition.

The partially hollow geometry of the implants (endplates and extension) allows them to be packed with bone graft. The implants are supplied sterile and are available in a variety of heights, footprints and anatomical shapes to accommodate patient anatomy.

The provided text is a 510(k) summary for the KONG®-TL VBR System and KONG®-C VBR System, which are vertebral body replacement systems. This type of document is for demonstrating substantial equivalence to a predicate device, not for proving the device meets specific acceptance criteria in the context of an AI/ML algorithm or software. Therefore, the requested information about acceptance criteria, detailed study design, expert qualifications, and AI/ML specific details (e.g., effect size of AI assistance, training set details) are not typically found in this kind of regulatory submission.

However, I can extract the information that is present and indicate where the requested details are not applicable or provided in this document.

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

This document does not provide a table of acceptance criteria and reported device performance in the manner typically seen for AI/ML performance metrics (e.g., sensitivity, specificity, AUC). Instead, it relies on demonstrating substantial equivalence to a predicate device through non-clinical and clinical data.

The relevant statement is:
"Non-clinical testing data and clinical data demonstrate the performance of the subject device is substantially equivalent to that of the predicate device, and support the performance of the subject device in its expanded indications for use."

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

The document mentions "clinical data provided" and "non-clinical testing data," but it does not specify the sample size used for any test set or the data provenance (e.g., country of origin, retrospective/prospective). It also states: "the provided clinical data did not support that the specific material or unique technological characteristics of the subject device components provides additional benefit relative to other vertebral body replacement devices for the indications for use related to infection."

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

This information is not provided in the document as it is not an AI/ML device performance study.

4. Adjudication method for the test set

This information is not provided in the document as it is not an AI/ML device performance 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

This is not applicable as the device is a physical vertebral body replacement system, not an AI/ML medical device designed to assist human readers.

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

This is not applicable as the device is a physical vertebral body replacement system, not an AI/ML medical device.

7. The type of ground truth used

The document refers to "clinical data" and "expanded indications for use," but does not explicitly define the type of ground truth used (e.g., pathology, outcomes data) in the context of device performance validation beyond demonstrating substantial equivalence. For a physical implant, "ground truth" would typically relate to the success of the implant in its intended function post-surgery, which is usually assessed through long-term follow-up and clinical outcomes. The document does not detail how this was established.

8. The sample size for the training set

This is not applicable as the document describes 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 is not applicable as the document describes a physical medical device.
