The Vertiwedge® Intraosseous System is indicated for use in the thoracolumbar spine (TI-L5) for partial replacement of a diseased or damaged vertebral body resected or excised to replace a portion and/or restore the height of a collapsed vertebral body for the treatment of previous trauma (i.e. fracture or tumor) or degenerative spine disease. The system is to be placed within the vertebral body following an osteotomy and supplemented with autograft or allograft and to be used with its contralateral staple; should a physician choose to use fewer than the maximum number of screws, then supplemental fixation must be used to augment stability.

The Vertiwedge® Intraosseous System is intended to restore the integrity of the spinal column even in the absence of fusion in patients with advanced stage turnors involving the thoracolumbar spine in whom life expectancy is of insufficient duration to permit achievement of fusion.

Vertiwedge® Intraosseous System is an intraosseous device that is used as a motion-preservation partial vertebral replacement device in the thoracolumbar spine in the motion-sparing Vertebral Body Osteotomy (VBO®) procedure. The Vertiwedge® Intraosseous device is used within a single osteotomized vertebral body, and it does not span any disc levels nor involve resection of or interference with the discs. The Vertiwedge® Intraosseous device is implanted through an anterior to psoas/oblique approach following an osteotomy of the vertebral body, in a Vertebral Body Osteotomy (VBO®) procedure The Vertiwedge® Intraosseous System consists of the intraosseous wedge (or spacer) with a lateral plate and a unique staple that provides integrated contralateral fixation. The Vertiwedge® Intraosseous System is available in a variety of heights and geometric options to accommodate variations in pathology and patient anatomy. Protrusions on the superior and inferior surfaces grip the osteotomized vedges to aid in expulsion resistance. The Vertiwedge® Intraosseous System is to be filled with autogenous bone graft and/or allogeneic bone graft material, and is to be used with the titanium alloy bone screws and cover plate to provide fixation within the single impacted vertebral body. All implant components are manufactured from Ti-6Al-4V ELI per ASTM F3001 or ASTM F136.

KONG®-C VBR System is intended to be used with supplemental fixation cleared by the FDA for use in the cervical spine.

These implants may be used with autograft or allogenic bone graft comprising cancellous and/or corticocancellous bone graft. These implants are 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 in whom life expectancy is of insufficient duration to permit achievement of fusion, with bone graft used at the surgeon's discretion.

When used with the icotec Anterior Cervical Plate System, the KONG®-C VBR 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.

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.

The DOMINION Expandable Corpectomy System is indicated for vertebral body replacement in the cervical spine (C2-Tl) and the thoracolumbar spine (T1-L5). The System is designed for use with autogenous and/or allogeneic bone graft comprised of cancellous and/or corticocancellous bone graft as an adjunct to fusion.

When used in the cervical spine (C2-T1), DOMINION spacers are in skeletally mature patients to replace a diseased or damaged vertebral body caused by tumor fracture or osteomyelitis, or for reconstruction following corpectorny performed to achieve decompression of the spinal cord and neural tissues in the cervical degenerative disorders. These spacers are 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 in whom life expectancy is of insufficient duration to permit achievement of fusion, with bone graft used at the surgeon's discretion. The System is intended to be used with supplemental fixation that has been cleared by the FDA for use in the cervical spine. When used in the thoracolumbar spine (T1-L5), DOMINION spacers are intended for use to replace a collapsed, damaged, or unstable vertebral body due to tumor or trauma (i.e. fracture). These spacers are designed to provide anterior spinal column support even in the absence of fusion for a prolonged period.

The system is intended to be used with supplemental fixation that has been cleared by the FDA for use in the thoracolumbar spine (i.e. posterior screw and rod systems, and anterior screw and rod systems). When used at more than two levels, supplemental fixation should include posterior fixation.

The Dominion Expandable Corpectomy system is a modular system comprised of Expandable Columns, Modular Endplates, and optional screws. The primary purpose of the Expandable Column is to provide mechanical support to the anterior column of the spine after a vertebral corpectomy is performed. The primary function of the Modular Endplates is to provide attachment points for the Expandable Column to the vertebral endplates. The screws are an optional device that can provide enhanced fixation to the vertebral endplates when desired. The system contains Inserters which allow the insertion and expansion of the Expandable Columns.

The document provided is a 510(k) premarket notification for a medical device (DOMINION Expandable Corpectomy System) and does not describe a study involving humans or AI for diagnostic purposes. Therefore, most of the requested information regarding acceptance criteria and study details cannot be extracted from this document because it is not relevant to this type of device submission.

Here's a breakdown of what can be inferred from the document and why other points cannot be addressed:

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

The document lists several non-clinical tests that were performed, which inherently have acceptance criteria. However, the specific acceptance criteria values (e.g., minimum compression strength, maximum torsion deformation) and the reported device performance values (the actual measurements from the tests) are not detailed in this summary. It only states that the following analyses were conducted:

The summary states, "Astura Medical considers the DOMINION Expandable Corpectomy Spacer to be equivalent to the predicate devices listed above. This conclusion is based upon the devices' similarities in principles of operation, technology, materials and indications for use." This implies that the non-clinical tests demonstrated performance comparable to or better than the predicate devices, thereby meeting relevant acceptance criteria established for such devices.

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

This information is not provided in a 510(k) summary for non-clinical (mechanical) testing. Sample sizes for mechanical tests are typically dictated by testing standards (e.g., ASTM standards) rather than patient data. Data provenance like country of origin or retrospective/prospective is not applicable to mechanical performance testing.

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 is not applicable as the device is a spinal implant, and the "ground truth" for its performance is established through mechanical testing against engineering standards, not through expert human interpretation of medical images or patient data.

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

Not applicable. Mechanical test results are objective measurements and do not typically require adjudication by experts in the same way clinical or diagnostic studies do.

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

The document explicitly states: "No clinical studies were performed." Therefore, an MRMC comparative effectiveness study was not done. This device is not an AI-powered diagnostic tool.

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 (expert consensus, pathology, outcomes data, etc.)

For this medical device, the "ground truth" for its safety and effectiveness is established through the adherence to recognized international and national mechanical testing standards (e.g., ASTM F2077, ASTM F2267) and the comparison of its performance to legally marketed predicate devices. It is based on engineering principles and material science, not clinical outcomes or expert consensus in a diagnostic sense.

8. The sample size for the training set

Not applicable. This device is not an AI system that requires a "training set."

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

Not applicable. As above, this device is not an AI system.

I am sorry, but the provided text does not contain information about the acceptance criteria or a study proving that a device meets the acceptance criteria. The document is an FDA 510(k) clearance letter for the "VerteLoc Spinal System," which describes the device, its indications for use, and a summary of technological characteristics compared to predicate devices. It also mentions non-clinical testing conducted, but it does not detail specific acceptance criteria, reported device performance against those criteria, or the methodology of an in-depth study to prove acceptance.

Therefore, I cannot provide the requested table or answer the specific questions about sample size, data provenance, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth establishment, or training set details.

Instead, it focuses on the substantial equivalence of the ArtFx Corpectomy Cages to a predicate device based on non-clinical mechanical testing.

Therefore, many of the requested categories related to AI performance, such as sample size for test set, data provenance, number of experts, adjudication method, MRMC studies, standalone performance, and training set information, are not applicable to the content of this document.

However, I can provide information about the acceptance criteria and the study that proves the device meets those criteria based on the non-clinical testing described.

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria are not explicitly stated in numerical terms within this 510(k) summary (e.g., "The device must withstand X N of compression"). However, the summary indicates that non-clinical testing was performed "according to the Guidance for Industry and FDA Staff Spinal System 510(k)s." This implies that the acceptance criteria are adherence to the performance requirements outlined in the specified ASTM standards and FDA guidance for spinal systems.

The reported device performance is that these tests were "performed" and presumably met the requirements of these standards to demonstrate substantial equivalence to the predicate device.

2. Sample Size Used for the Test Set and Data Provenance

The document only mentions "Non-clinical testing including below tests are performed". For mechanical testing of medical devices, the "sample size" typically refers to the number of devices or representative constructs tested for each specific test. This specific number is not explicitly stated in the provided 510(k) summary.

Data Provenance: Not applicable as this is non-clinical mechanical testing, not human data.

3. Number of Experts Used to Establish Ground Truth and Qualifications

Not applicable. Ground truth establishment with experts is relevant for clinical studies or AI/diagnostic device performance evaluation, not for mechanical device testing.

4. Adjudication Method for the Test Set

Not applicable. Adjudication methods are relevant for clinical studies or AI/diagnostic device performance evaluation, not for mechanical device testing.

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

No. An MRMC study involves human readers interpreting cases, often with and without AI assistance. This document describes non-clinical mechanical testing of a physical medical device (corpectomy cages) and does not involve AI, human readers, or cases in this context.

6. Standalone Performance Study

Yes, in a sense, the non-clinical tests described (Dynamic Compression, Static Compression, Subsidence, Expulsion tests) represent a "standalone" evaluation of the device's mechanical performance without human interaction during the test itself. The performance is assessed against established engineering standards rather than against human performance.

7. Type of Ground Truth Used

The "ground truth" for this type of testing is established through industry standards and regulatory guidance. The device's performance is compared against the requirements and specifications outlined in the ASTM standards (F2077, F2267) and FDA guidance for spinal systems, which define acceptable mechanical properties and behaviors for such devices.

8. Sample Size for the Training Set

Not applicable. There is no AI or machine learning component mentioned that would require a training set. This is a physical medical device.

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

Not applicable, as there is no training set.

When used in the cervical spine (C2-T1), F3D Corpectomy devices are intended for use in skeletally mature patients to replace a diseased or damaged vertebral body caused by tumor fracture or osteomyelitis, or for reconstruction following corpectomy performed to achieve decompression of the spinal cord and neural tissues in cervical degenerative disorders. These spacers are 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 in whom life expectancy is of insufficient duration to permit achievement of fusion, with bone graft used at the surgeon's discretion.

When used in the thoracolumbar spine (T1-L5), F3D Corpectomy devices are intended for use to replace a collapsed, damaged, or unstable vertebral body due to tumor or trauma (i.e., fracture). These spacers are designed to provide anterior spinal column support even in the absence of fusion for a prolonged period.

The interior of the spacers can be packed with autograft or allogenic bone graft comprising cancellous and/or corticocancellous bone graft and/or demineralized allograft bone with bone marrow aspirate as an adjunct to fusion.

These devices are intended to be used with FDA-cleared supplemental spinal fixation systems that have been labeled for use in the cervical, thoracic, and/or lumbar spine (i.e., posterior screw and rod systems, anterior plate systems, and anterior screw and rod systems). When used at more than two levels, supplemental fixation should include posterior fixation.

The F3D Corpectomy Cage is a spinal vertebral body replacement device which is available in a variety of different heights, footprints, and lordotic options to suit the individual pathology and anatomical conditions of the patient. The F3D Corpectomy cage consists of a static, single-piece vertebral body replacement cage. The F3D Corpectomy devices are intended for use in the cervical (C2-T1) and thoracolumbar spine (T1-L5). They are designed to provide mechanical support to the spine while arthrodesis occurs. The F3D Corpectomy System is made from titanium alloy (Ti-6Al-4V) per ASTM F3001.

The FDA 510(k) summary for the F3D Corpectomy System (K202637) focuses on establishing substantial equivalence to predicate devices through technical characteristics and mechanical performance testing, rather than an AI/ML context. Therefore, many typical AI/ML study components (like expert ground truth, adjudication, MRMC studies, training set details) are not applicable or mentioned.

Here's an analysis of the provided text, outlining the acceptance criteria and the study performed, along with the information that is not available given the nature of this medical device clearance (spinal implant, not an AI/ML device):

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state numerical acceptance criteria in the format of a table with specific thresholds. Instead, it refers to industry standards (ASTM F2077 and ASTM F2267) and concludes that the device's strength is "sufficient for its intended use" and "substantially equivalent to legally marketed predicate devices."

2. Sample Size Used for the Test Set and Data Provenance

• Sample Size: Not explicitly stated as a number of devices. The tests are typically performed on a statistically relevant number of physical device samples as required by the ASTM standards, but the exact count is not disclosed in the summary.
• Data Provenance: The tests are non-clinical, meaning they were performed in a laboratory setting ("Performance Data" section). There is no mention of patient data (retrospective or prospective) or country of origin for such data, as this is a mechanical safety and performance study for a physical implant.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

• This information is not applicable as the evaluation is based on mechanical laboratory testing against industry standards, not on interpretation of medical images or patient outcomes requiring expert consensus.

4. Adjudication Method for the Test Set

• This information is not applicable as there is no human interpretation or decision-making process for the mechanical test results that would require adjudication.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs without AI Assistance

• This information is not applicable. The F3D Corpectomy System is a physical spinal implant, not an AI/ML-driven diagnostic or assistive device that would involve human readers.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

• This information is not applicable. The device is a physical implant and does not involve an algorithm.

7. The Type of Ground Truth Used

Here's an analysis based on your request:

1. Table of Acceptance Criteria and Reported Device Performance:

The document does not explicitly present "acceptance criteria" in a typical quantitative sense (e.g., target accuracy, sensitivity/specificity values). Instead, the performance testing aims to demonstrate substantial equivalence to legally marketed predicate devices by conforming to established ASTM standards for various mechanical properties. The "reported device performance" are the results from these tests, which were deemed sufficient to show equivalence.

2. Sample Size Used for the Test Set and Data Provenance:

The document describes non-clinical mechanical performance testing. This typically involves physical samples of the medical device or its components.

• Sample Size: Not explicitly stated in terms of a numerical count of tested devices. It refers to "worst-case construct" for expulsion testing, implying selection based on anticipated highest stress. For other tests, it's implied that a statistically relevant number of samples were tested to meet ASTM standard requirements, but the exact number is not provided in this summary.
• Data Provenance: The tests are non-clinical (benchtop, laboratory testing) performed by "the company" (icotec ag). Since it's mechanical testing of the device itself, there is no patient data or "country of origin of the data" in the sense of clinical study demographics.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:

This question is not applicable. The study is a non-clinical mechanical performance test, not a clinical study involving diagnosis or interpretation by experts. The "ground truth" here is compliance with engineering standards and mechanical integrity, not medical findings.

4. Adjudication Method for the Test Set:

This question is not applicable. There is no expert adjudication needed for non-clinical mechanical testing. The results are typically objectively measured and compared against standard specifications.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done:

No, an MRMC comparative effectiveness study was not done. This submission focuses on non-clinical mechanical performance testing to demonstrate substantial equivalence to predicate devices, not on a clinical comparison involving human readers or AI assistance.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done:

No, this question is not applicable. The device (KONG®-TL VBR System and KONG®-C VBR System) is a physical medical implant, not an AI algorithm or software device.

7. The Type of Ground Truth Used:

The "ground truth" for this non-clinical performance evaluation is based on established engineering standards (ASTM F2077, ASTM F2267) and the mechanical properties and performance of legally marketed predicate devices. The testing aims to show that the subject device performs similarly or meets the safety and effectiveness requirements defined by these standards, thereby demonstrating substantial equivalence.

8. The Sample Size for the Training Set:

This question is not applicable. Since the device is a physical implant and the study is non-clinical mechanical testing, there is no "training set" in the context of an algorithm or statistical model.

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

This question is not applicable as there is no "training set" for this type of device and study.

Small VBR™ is a system of corpectomy devices used to provide mechanical support to the cervical and thoracolumbar spine. Small VBR™ is a cylindrical implant with the capability for device expansion. The ends of the device incorporate a ring of teeth to engage the endplates of adjacent vertebrae. The device is offered non-sterile in various combinations of expansion range, angulation and footprint to accommodate patient anatomy.

The provided text is a 510(k) premarket notification for a medical device called "Small VBR™" (Vertebral Body Replacement). This document describes the device, its intended use, and its equivalence to legally marketed predicate devices, primarily through mechanical testing.

**Crucially, this document does not describe a study involving:

• Acceptance criteria based on AI or diagnostic performance metrics (e.g., sensitivity, specificity, AUC).
• Human readers, radiologists, or expert consensus for ground truth establishment.
• Training or test sets for an algorithm.
• Multi-reader multi-case (MRMC) comparative effectiveness studies.**

Instead, the performance data section states: "Mechanical testing of the worst case Small VBR™ devices included static and dynamic compression and static and dynamic torsion following ASTM F2077. The mechanical test results demonstrate that Small VBR™ device performance is substantially equivalent to itself as a predicate device."

Therefore, based solely on the provided text, I cannot fulfill the request to describe acceptance criteria and a study that proves the device meets those criteria in the context of diagnostic performance or AI. The study described is a mechanical testing study for a spinal implant, comparing its physical performance to a predicate device.

Here's what I can extract based on the provided text about the mechanical testing:

• Sample Size: Not explicitly stated but implied to be "worst case Small VBR™ devices" for mechanical testing. For mechanical testing, this typically refers to a representative number of devices to ensure statistical validity, but the exact count isn't given.
• Data Provenance: Not applicable in the context of patient data. The "data" refers to mechanical test results from the manufactured devices.

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

• Not applicable. Ground truth for mechanical testing is established by engineering standards (ASTM F2077) and the physical properties of the device, not by expert human interpretation.

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

• Not applicable. This is a mechanical engineering test, not a diagnostic study requiring human adjudication.

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 device is a physical spinal implant, not an AI-powered diagnostic tool.

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

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

7. The type of ground truth used:

• The ground truth is established by the ASTM F2077 standard for mechanical testing of spinal implants.

8. The sample size for the training set:

• Not applicable. This is not an AI/machine learning study.

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