It is intended that this device, in any system configuration, be removed after development of solid fusion mass. Hook components are indicated for use at C1-C7. Polyaxial pedicle screws and offset connectors are limited to the thoracic spine (T1-T3) in treating thoracic conditions only. These screws and offset connectors are not intended to be placed in the cervical spine. The components in the SOLANAS Posterior stabilization system can be linked to the components in the Zodiac Polyaxial spinal fixation system offered by Alphatec Spine using the axial rod connectors, parallel rod connectors or transitional rods

The Solanas Posterior Stabilization System facilitates the surgical correction of spinal deformities by providing temporary internal fixation and stabilization during bone graff healing and/or fusion mass development. Device implants include a range of sizes of bone screws, hooks, rods and bridge assemblies to provide the versatility required for the specific conditions listed in the indications. The implants are manufactured from surgical grade titanium alloy (Ti-6AI-4V, ASTM F 136) with an electrolytic conversion coating. All hook components are intended for fixation/attachment to the cervical spine only (CI-C7). It is intended that the implants be removed after successful fusion.

The Solanas Posterior Stabilization System is a rod system designed to improve the stability of the cervical, cervico-thoracic and upper thoracic spine from C1-T3. This titanium alloy (Ti6Al-4V ELI, ASTM F136) system is simple in design and in its application of posterior rod fixation. It contains integrated functioning screws, rods, hooks, and connectors. The laminar hooks are an integral part of this system providing stabilization to the cervical (C1-C7) portion of the spine. These hooks attach to the lamina via the blade portion of the hook on one end and to a rod via a set screw and collar connection on the other end.

The provided text is related to a 510(k) premarket notification for a medical device called the "Solanas Posterior Stabilization System." This document is a regulatory filing for a spinal implant system and does not describe a study involving device performance metrics, human readers, or AI.

Therefore, I cannot extract information related to:

• A table of acceptance criteria and reported device performance (in terms of clinical or algorithmic metrics)
• Sample sizes for test sets or data provenance in the context of device performance
• Number and qualifications of experts for ground truth
• Adjudication methods
• Multi-reader multi-case (MRMC) comparative effectiveness studies
• Standalone algorithm performance studies
• Type of ground truth used (expert consensus, pathology, outcomes data)
• Sample size for the training set
• How ground truth for the training set was established

However, I can provide information about the non-clinical testing performed to establish substantial equivalence for this spinal implant system.

Based on the provided text, here is the relevant information:

Acceptance Criteria and Study for the Solanas Posterior Stabilization System (Mechanical Testing)

The Solanas Posterior Stabilization System is a spinal implant. The "acceptance criteria" and "study" mentioned in the document refer to mechanical testing performed to demonstrate that the modified device (with larger hook blades of 7mm and 8mm) is substantially equivalent to a previously cleared predicate device.

Table of Acceptance Criteria and Reported Device Performance

2. Sample size used for the test set and the data provenance:

• Sample size: The document does not specify the exact number of units or subassemblies tested. It refers to "a subassembly" and "the subject and predicate devices."
• Data provenance: Not applicable in the context of mechanical testing of physical devices. The testing was performed by Alphatec Spine, Inc.

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 was mechanical testing of a medical device, not a study involving ground truth established by medical experts. The "ground truth" here is the adherence to mechanical testing standards.

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

• Not applicable. This refers to consensus among human readers, which is not relevant for mechanical testing.

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 a 510(k) for a physical spinal implant, not an AI or imaging device.

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

• Not applicable. This is for a physical spinal implant, not an algorithm.

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

• For this mechanical test, the "ground truth" or reference standard would be the established mechanical testing standards and parameters defined in ASTM F1798 and FDA guidance documents. The performance of the modified device was compared against these standards and the predicate device's performance.

8. The sample size for the training set:

• Not applicable. This refers to mechanical testing, not a dataset used for training an algorithm.

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

• Not applicable.

In summary: The provided document describes a regulatory submission for a physical medical device. The "study" mentioned is a mechanical performance comparison to demonstrate substantial equivalence, rather than a clinical trial or an AI/imaging device performance study with expert-adjudicated ground truth.
