The Posterior Cable Screw System is designed as an adjunct to any stainless steel, rigid, posterior fixation cleared/approved for trauma and spondylolithesis and is intended to reduce pars defect and to stabilize the spinal operative site during fusion procedures. A spinous process Grommet is included as part of the system. The system is designed as an adjunct to any stainless steel, rigid, posterior fixation and is indicated for the following:

Defect of the pars interarticularis .
Spondylolithesis .

The Posterior Cable Screw System is indicated for pedicle screw attachment for these indications between T1 and the sacrum.

Cables and spinous process Grommets may be used for interspinous wiring if additional stability is needed.

AI/ML Overview

The provided text describes a 510(k) summary for the Pioneer Posterior Cable Screw, a medical device. This type of submission focuses on demonstrating substantial equivalence to a predicate device rather than comprehensive clinical studies with detailed acceptance criteria and standalone performance evaluations as would be expected for novel devices or software.

Therefore, much of the requested information regarding acceptance criteria, specific study details (sample size for test sets, data provenance, expert qualifications, adjudication methods, MRMC studies, standalone performance), and ground truth establishment is not available in the provided document, as it falls outside the scope of a typical 510(k) summary focused on hardware equivalence.

Here's a breakdown of what can be extracted and what is missing:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria	Reported Device Performance
Material Equivalence: Comprised of implant grade stainless steel (ASTM F138 and ISO 5832-1)	Implied to meet this, as the material is stated to be "Implant grade stainless steel (ASTM F138 and ISO 5832-1.)"
Mechanical Performance: Equivalent mechanical properties to predicate device.	"Mechanical information was presented to support a determination of PERFORMANCE SE [Substantial Equivalence]." (Specific metrics or thresholds not detailed).
Intended Use Equivalence: Similar intended use as predicate device.	"The Posterior Cable Screw System is designed as an adjunct to any stainless steel, rigid, posterior fixation cleared/approved for trauma and spondylolisthesis and is intended to reduce pars defect and to stabilize the spinal operative site during fusion procedures." (Matches or is similar to predicate).
Design Equivalence: Similar to components of a previously cleared device.	"The Pioneer Posterior Cable Screw system is similar to the components of a previously cleared device." (Specific design details not provided).

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

Not Applicable/Not Provided. The submission is for a mechanical spinal implant and focuses on substantial equivalence based on material and mechanical properties, not a clinical study on a test set of data (e.g., images for an AI device).
Data Provenance: Not applicable. Performance is based on material standards and mechanical testing, not a dataset from a specific country or retrospective/prospective study with human subjects.

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

Not Applicable/Not Provided. This information is relevant for studies involving human interpretation or clinical outcomes, which are not detailed in this 510(k) summary.

4. Adjudication method for the test set

Not Applicable/Not Provided. No test set requiring expert adjudication 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

No. This is a hardware device (spinal implant), not a software/AI device. Therefore, an MRMC study is not relevant or described.

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

Not Applicable. This is a hardware device. "Standalone performance" in the context of AI algorithms is not relevant here. The "standalone" performance would be its mechanical integrity, which is assessed through testing that is not detailed in terms of its specific methodology or standalone vs. human-in-the-loop comparison.

7. The type of ground truth used

Not Applicable/Not Provided in the typical AI/clinical study sense. For this device, "ground truth" relates to:
- Material composition: Confirmed by adherence to ASTM F138 and ISO 5832-1 standards.
- Mechanical performance: Confirmed through testing (implied by "Mechanical information was presented") against accepted engineering criteria, likely benchmarking against the predicate device.
- Clinical Efficacy/Safety: Not directly proven in this 510(k) summary; rather, it is inferred by substantial equivalence to a device with an established safety and efficacy profile.

8. The sample size for the training set

Not Applicable/Not Provided. This pertains to AI/machine learning models, which is not the subject of this 510(k). For mechanical testing, the number of samples tested for mechanical properties is not specified.

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

Not Applicable/Not Provided. As there's no AI "training set" described, this question is not relevant. The "ground truth" for the device's material and mechanical properties would be established through accredited laboratory testing and adherence to recognized material and performance standards.
