Clinical Diagnostic PerformanceNo criteria for clinical diagnostic performance (e.g., sensitivity, specificity, accuracy) are mentioned as this is a spinal stabilization device, not a diagnostic AI system.Not applicable - this document does not describe a diagnostic AI system or clinical performance study.

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

  • Sample Size for Test Set: Not applicable. The document describes bench tests and functional cadaver tests. No "test set" of patient data for diagnostic evaluation is mentioned.
  • Data Provenance: Not applicable. The tests involved cadaveric specimens and laboratory equipment.

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. There is no mention of experts establishing ground truth for a diagnostic test set. The cadaver implantation testing assessed the ability of "users" to perform surgical techniques, but no specific number or qualifications are provided, and this is not establishing ground truth for a diagnostic outcome.

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

  • Not applicable. No diagnostic test set or adjudication method 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, an MRMC comparative effectiveness study was not done, and this device is not presented as an AI-assisted diagnostic tool.

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

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

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

  • Not applicable. The "ground truth" for the performance described is based on established engineering standards (ASTM, ISO) for mechanical stability, biocompatibility, and MR compatibility, and the observable success of surgical implantation in cadavers, rather than clinical diagnostic outcomes.

8. The sample size for the training set

  • Not applicable. There is no mention of a training set as this is not an AI/machine learning device.

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

  • Not applicable.
