The Sovereign Posterior Cervical System is intended to provide immobilization and stabilization of spinal segments as an adjunct to fusion for the following acute and chronic instabilities of the cervical spine (C1 to C7) and the thoracic spine (T1-T3): traumatic spinal fractures and/or traumatic dislocations; instability or deformity; failed previous fusions (e.g. pseudoarthrosis); tumors involving the cervical/thoracic spine; and degenerative disease, including intractable radiculopathy and/or myelopathy, neck and/or arm pain of discogenic origin as confirmed by radiographic studies, and degenerative disease of the facets with instability.

The Sovereign Posterior Cervical System is also 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.

In order to achieve additional levels of fixation, the Sovereign Posterior Cervical System may be connected to the Xultan 5.5 system using rod-to-rod connectors or transition rods. Please refer to the individual system's Instructions for Use for a list of indications for use for each system.

The Met One Technologies Sovereign Posterior Cervical System is an implant device designed for the posterior stabilization of the cervical and upper thoracic spine. The system includes implants such as polyaxial screws, blocker screws, rods, crosslinks, lateral connectors, and rod to rod connectors to form a unique construct to match patient anatomy.

Polyaxial screws are offered in a range of sizes in both standard and reduction tulips for ease of use. All screws are manufactured from titanium alloy (Ti-6Al-4V ELI per ASTM F136).

Straight, pre-bent, and transition rods are offered in 3.5mm and 4.0mm diameters and in two different materials, titanium alloy (Ti-6Al-4V ELI per ASTM F136) and cobalt chrome (Co-Cr28-Mo6 per ASTM F1537). Transition rods are fully compatible with Met One Technologies Xultan 5.5 Pedicle Screw System line of implants.

A variety of connectors and crosslinks are offered for surgeons to create the desired construction. Rod to rod crosslinks improve the torsional stability of the construct.

Rod to rod connectors are offered in several configurations to join rods together. All connectors are manufactured from titanium alloy (Ti-6Al-4V ELI per ASTM F136).

I am sorry, but the provided text is an FDA 510(k) clearance letter for a Sovereign Posterior Cervical System, which is a physical medical device (spinal implant system), not an AI/Software as a Medical Device (SaMD).

Therefore, the document does not contain any information about:

• Acceptance criteria for an AI/SaMD's performance.
• A study proving the device meets AI/SaMD acceptance criteria.
• A test set (sample size, provenance).
• Experts establishing ground truth.
• Adjudication methods.
• MRMC comparative effectiveness studies.
• Standalone algorithm performance.
• Types of ground truth.
• Training set details.

The non-clinical testing described (ASTM F1717 and ASTM F1798) refers to mechanical testing of the physical implant's strength and durability, not software performance.

As such, I cannot fulfill your request for information related to AI/SaMD acceptance criteria and study details based on the provided input.

The Kodiak Lumbar Spacer System is indicated for spinal fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels in the lumbar spine (L2-S1) with up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. Patients with previous non-fusion spinal surgery at the involved level may be treated with the Kodiak Lumbar Spacer System. Patients must have undergone a regimen of at least six (6) months of nonoperative treatment prior to being treated with the Kodiak Lumbar Spacer System.

The Kodiak Lumbar Spacer System is designed for use with autogenous bone graft. The system is also intended to be used with supplemental fixation systems that are cleared by the FDA for use in the lumbar spine.

The Met One Technologies Kodiak Lumbar Spacer System is a lumbar intervertebral body fusion device that is implanted into the vertebral body space to improve stability of the spine while supporting fusion. The Kodiak Lumbar Spacer System may be implanted bilaterally using a posterior (PLIF) approach, or as a single device employing a transformational (TLIF) approach. The implants have a central endplate window to permit packing of autograft and/or allograft bone, teeth on the superior and inferior surfaces, and lateral windows for radiographic visualization. The implants are additively manufactured from Ti-6A1-4V ELI and are available in a variety of heights, footprints, and lordotic configurations to suit individual patient anatomy.

The provided text describes the 510(k) premarket notification for the "Kodiak Lumbar Spacer System," an intervertebral body fusion device. This document is a regulatory submission for a medical device that does not involve Artificial Intelligence (AI).

The requested information pertains to studies proving device performance with AI, such as acceptance criteria for AI model performance, sample sizes for AI training and test sets, expert adjudication methods for AI ground truth, and AI-assisted reader studies. Since the Kodiak Lumbar Spacer System is a physical implant and not an AI-powered diagnostic or therapeutic tool, this document does not contain any of the information requested about AI device performance studies.

The "Performance Data" section lists several types of mechanical tests performed on the device in accordance with ASTM standards (e.g., Static Compression, Dynamic Compression, Subsidence, Expulsion). These tests are standard for orthopedic implants to demonstrate their structural integrity and function, but they are not related to AI performance.

Therefore, I cannot provide the requested information because the provided document does not discuss an AI device or its performance studies.

This document is a 510(k) Summary for the Kodiak C Spinal Implant System, a medical device. It focuses on demonstrating substantial equivalence to predicate devices, rather than presenting a study proving performance against specific acceptance criteria in the context of AI/ML or diagnostic performance.

Therefore, the information requested regarding acceptance criteria, study details (sample size, data provenance, expert qualification, adjudication, MRMC, standalone performance, ground truth), training set sample size, and ground truth establishment cannot be fully provided from the given document. This document describes mechanical and material testing, not diagnostic or AI performance.

Here's an attempt to answer based on the provided text, highlighting what is present and what is missing:

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

The document lists performance tests conducted, but it does not explicitly state quantitative acceptance criteria or reported numerical performance values for these tests. It only states that the device "demonstrated substantial equivalence" to predicate devices, implying that the results met relevant industry standards (e.g., ASTM standards) but without providing the actual data or specific thresholds.

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

• Test set sample size: Not specified. The document refers to "the following test modes" and implies mechanical testing of devices, not clinical studies with patient data.
• Data provenance: Not applicable in the context of mechanical device testing. The tests are likely performed in a lab setting.

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. This is a medical device approval involving mechanical properties and material composition, not diagnostic interpretation by experts. Ground truth in this context would refer to material specifications and engineering standards, not expert medical opinions.

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

• Not applicable. Adjudication methods are relevant for subjective interpretations of data, not for objective mechanical test results.

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. This document does not mention any MRMC study or AI assistance. The device is a physical spinal implant.

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

• No. This document does not pertain to an algorithm or AI.

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

• The "ground truth" for this type of device (spinal implant) would be established by engineering specifications, material standards (e.g., ASTM F3001 for Ti-6Al-4V ELI), and biomechanical testing standards (e.g., ASTM F2077, ASTM F2267). The device's performance is compared against these known, objective standards to demonstrate substantial equivalence to legally marketed predicate devices.

8. The sample size for the training set

• Not applicable. This document does not describe an AI/ML device that requires a training set.

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

• Not applicable. This document does not describe an AI/ML device.
