The Talos® IBF Device is an intervertebral body device intended for use in skeletally mature patients with Degenerative Disc Disease (DDD) of the lumbar spine with up to Grade 1 spondylolisthesis at one or two contiguous levels from L2-S1. Degenerative disc disease is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. Talos® IBF Devices are intended to be used with autograft comprised of cancellous and/or corticocancellous bone graft.

The Talos® IBF Device is to be used in patients who have had six months of non-operative treatment. Talos® IBF devices are to be implanted via a direct posterior, transforaminal, lateral, or anterior approach in the lumbosacral spine. The Talos®-A, Talos®-L, Talos®-T are intended to be used with supplemental fixation.

The Talos®-C Cervical Intervertebral Body Fusion Device is an intervertebral body device intended for use in sketally mature patients with Degenerative Disc (DDD) of the cervical spine at one level from C2-T1. Cervical degenerative disc disease is defined as intractable radior myelopathy with herniated disc and/or osteophyte formation on the posterior vertebral endplates producing symptomatic nerve root and/or spinal cord compression confirmed by history and radiographic studies. Talos®-C Cervical IBF Devices are intended to be used with autograft and/or allograft comprised of cancellous and/or corticocancellous bone graft.

The Talos® IBF Device is made of polymer, polyetheretherketone (PEEK). The Talos® IBF Device is available in four configurations: Talos®-P, Talos®-L, and Talos®-A. The devices are open devices with ridged teeth on superior and inferior ends to resist implant pullout. The Talos® –P and Talos® –L are rectangular devices and the Talos® – A have curved lateral walls and rounded edges. The implants are available in a range of sizes, as well as flat and lordotic angled implants to accommodate variations in patient's anatomy. In addition, tantalum markers at the opposite ends are offered which allow the Talos® IBF radiological confirmation for proper positioning.

This document is a 510(k) premarket notification for Meditech Spine, LLC's Talos® Intervertebral Body Fusion Devices. It focuses on changes to previously cleared devices, specifically the addition of allograft bone options and a change in marker material for cervical devices.

Based on the provided text, the device itself (hardware) has not undergone changes, but the submission is for modifications to the indications for use concerning bone graft material and material change for radiopaque markers. Therefore, the acceptance criteria and study information relate to demonstrating that these proposed changes do not introduce new safety or effectiveness concerns, and that the device remains substantially equivalent to its predicate devices.

Here's the breakdown of the requested information based solely on the provided text:

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

The document does not explicitly state "acceptance criteria" in a quantitative table format for device performance (e.g., accuracy, sensitivity, specificity). Instead, the acceptance criteria are implicitly that the modified indications and marker material do not increase risk and maintain substantial equivalence to the predicate devices. The "reported device performance" is framed in terms of clinical outcomes from published literature for similar devices.

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 explicitly stated as a specific number of patients or cases. The document refers to "Published retrospective clinical data" rather than a newly conducted study by the submitter.
• Data Provenance: "Published retrospective clinical data for lumbar and cervical intervertebral body fusion devices similar to the Talos® Intervertebral Body Fusion Devices..." No specific country of origin is mentioned.

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 the clinical data referenced is "published retrospective clinical data," details about expert review for ground truth within those studies would not typically be part of this 510(k) summary.

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

This information is not provided in the document, as it refers to existing published literature rather than a new study with a specific adjudication protocol.

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

• MRMC study done? No. This document is for intervertebral body fusion devices, not an AI-assisted diagnostic tool for which an MRMC study would be relevant.
• Effect size of human reader improvement with AI? Not applicable.

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

• Standalone study done? No. This document is for intervertebral body fusion devices, not a standalone AI algorithm.

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

The document references "published clinical outcomes" for similar devices. This implies that the "ground truth" for the effectiveness of allograft in fusion procedures would be based on clinical outcomes data (e.g., fusion rates, patient reported outcomes, absence of complications) from those retrospective studies.

8. The sample size for the training set

The concept of a "training set" is not applicable here as this is not an AI/ML device being developed or validated. The document refers to existing published clinical literature.

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

Not applicable, as this is not an AI/ML device, and no "training set" in that context is referenced. The "ground truth" in the context of the referenced clinical literature would have been established through standard clinical follow-up and evaluation methods of the respective studies.

Not Found

I apologize, but the provided text from the FDA 510(k) clearance letter for the Talos®-C Cervical Intervertebral Body Fusion Devices does not contain the information necessary to describe the acceptance criteria and the study proving the device meets those criteria in the context of an AI/ML medical device.

The document is a traditional 510(k) clearance letter for a physical medical device (an intervertebral body fusion device). It focuses on substantial equivalence to a predicate device, manufacturing regulations, and labeling requirements. It does not discuss:

• Acceptance Criteria for AI/ML performance: The concept of sensitivity, specificity, AUC, etc., for an AI/ML algorithm.
• Device Performance Metrics: There are no reported performance metrics for an AI/ML model here.
• Sample Size, Ground Truth, Expert Annotations: These are specific to the validation of AI/ML algorithms and are not relevant to the clearance of an orthopedic implant like the Talos®-C.
• MRMC Studies or Standalone AI Performance: These study designs are used to evaluate diagnostic AI and are not applicable to the clearance of a surgical implant.

Therefore, I cannot fulfill your request based on the provided text. To answer your question, I would need a document related to the clearance or validation of an AI/ML medical device.
