When used as a cervical intervertebral body fusion device, the Aleutian implants are indicated for spinal fusion procedures to be used with autogenous bone graft in skeletally mature patients. Cervical IBF implants are intended for use at one level in the cervical spine, from C2 to T1, for the treatment of cervical disc disease (defined as neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies). The cervical device is intended to be used in patients who have had six weeks of non-operative treatment.

When used as a lumbar intervertebral body fusion device, the Aleutian implants are indicated for spinal fusion procedures to be used with autogenous bone graft in skeletally mature patients. The lumbar IBF implants are intended for use at either one levels in the lumbar spine, from L2 to S1, for the treatment of degenerative disc disease (DDD) with up to Grade 1 spondylolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The lumbar device is intended to be used in patients who have had six months of non-operative treatment.

When used as vertebral body replacement devices the Aleutian implants are indicated for use in the thoracolumbar spine (T1 to L5) for partial replacement (i.e., partial vertebrectomy) of a diseased vertebral body, resected or excised for the treatment of tumors or trauma/fracture in order to achieve anterior decompression of the spinal cord and neural tissues, and to restore the height of a collapsed vertebral body. The Aleutian implants are designed to restore the biomechanical integrity of the anterior, middle, and posterior spinal column even in the absence of fusion for a prolonged period.

For all the above indications the Aleutian implants are intended to be used with supplemental internal fixation appropriate for the implanted level, including K2M Pedicle Screw and Hook Systems, and K2M Spinal Plate Systems.

The Aleutian Spinal System consists of a hollow tube or horseshoe-shaped structures. 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.

Materials: The implants are manufactured from Medical Grade PEEK per ASTM F2026. Tantalum beads/ rods are to be made of Grade UNS R05200, UNS R05400 according to ASTM F560.

Function: The system functions as an intervertebral body fusion device to provide support and stabilization of the cervical and lumbar segments of the spine.

The purpose of this submission is to incorporate titanium implants into the system.

The provided text is a 510(k) summary for the Aleutian IBF System, which describes the device, its intended use, and its substantial equivalence to predicate devices. It does not contain any information about acceptance criteria, study data, sample sizes, ground truth establishment, or expert involvement.

Therefore, I cannot provide the requested table and study details. The document explicitly states:

"An engineering rationale determined that the proposed spacers do not represent a new worst case for testing and are therefore considered substantially equivalent to the predicates referenced."

This indicates that the submission relies on an engineering rationale and comparison to previously cleared devices rather than a new standalone study with performance metrics in the format requested.

The provided text describes a 510(k) summary for the Aleutian IBF System, which is an intervertebral body fusion device. The submission focuses on demonstrating substantial equivalence to previously cleared devices rather than providing detailed acceptance criteria and a study proving those criteria are met for performance.

Here's an analysis based on the provided text:

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

The document does not explicitly state acceptance criteria in terms of clinical performance metrics (e.g., successful fusion rates, complication rates, improvement in patient-reported outcomes). Instead, the acceptance criteria appear to be related to the biomechanical equivalence of the device's design and materials to predicate devices.

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

The document does not describe a clinical study with a test set of patients or specimens for performance evaluation. The "study" mentioned is a finite element analysis (FEA), which is a computational simulation. Therefore, there is no sample size in the traditional sense, nor is there data provenance in terms of country or retrospective/prospective collection from patients.

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. Since no clinical test set or human expert review of performance data is described, there's no mention of experts establishing ground truth for a test set. The FEA would have been designed and interpreted by engineers, but their number and qualifications are not provided here.

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

Not applicable. No test set requiring adjudication in the clinical sense is described.

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 is not an AI-based device, and no MRMC study or comparative effectiveness study involving human readers is mentioned.

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

This is not an algorithm or AI device. The "standalone" performance, in this context, would be the structural integrity and biomechanical performance of the device itself, which was evaluated via FEA.

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

For the biomechanical evaluation (FEA), the "ground truth" is derived from established engineering principles, material properties (e.g., ASTM F2026 for PEEK, ASTM F560 for Tantalum), and the specified testing standard (ASTM F2077). This is a simulated ground truth based on accepted scientific and engineering methodologies, not biological ground truth from patients.

8. The sample size for the training set

Not applicable. This is not an AI device, so there is no training set. The FEA model is built based on design specifications and material properties, not trained on data.

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

Not applicable. As there is no training set for an AI model, there's no ground truth established for it.

This is a 510(k) premarket notification for a medical device, not a study evaluating device performance against acceptance criteria using AI or machine learning. Therefore, the requested information (table of acceptance criteria, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth types, and training set details) is not applicable or available in the provided document.

The document describes the Aleutian IBF System, an intervertebral body fusion device, and seeks to demonstrate its substantial equivalence to previously cleared predicate devices. The review process for 510(k) submissions relies on demonstrating that a new device is as safe and effective as a legally marketed predicate device, rather than requiring a detailed clinical study with specific acceptance criteria that an AI or machine learning model would typically be held to.

Here's a breakdown of why the requested information is not present:

• Acceptance Criteria & Reported Device Performance: In a 510(k), the "acceptance criteria" are usually satisfied by demonstrating substantial equivalence to a predicate device through comparison of technological characteristics, materials, and intended use. Performance is typically established by showing that the new device is functionally similar to the predicate. No specific numerical performance metrics with acceptance thresholds are provided, as would be expected for an AI study.
• Sample Size, Data Provenance, Experts, Adjudication, MRMC, Standalone Performance, Ground Truth, Training Set: These concepts are central to studies validating AI/ML algorithms, where statistical rigor is applied to evaluate a model's diagnostic or predictive accuracy. The provided document is a regulatory submission for a physical implantable device, relying on the established safety and efficacy of similar existing devices. It does not involve any AI/ML components or a study of performance in the way described.

In summary, the provided text is a 510(k) summary for a physical medical device and does not contain the type of study data and analysis requested for an AI/ML-based device evaluation.
