The Medtronic Anterior Cervical Plate Systems consist of a variety of shapes and sizes of bone plates (set screws and washers are pre-assembled to the plates) and screws. The Medtronic Anterior Cervical Fusion System consist of variety of shapes and sizes of bone plates (set screws and washers are pre-assembled to the plates), interbody cages, and screws. Fixation is provided by bone screws and/or interbody cages inserted into the vertebral body of the cervical spine using an anterior approach. The Medtronic Anterior Cervical Plate and Fusion Systems implant components are made from titanium alloy, with certain plates having subcomponents manufactured from shape memory alloys (Nitinol-NiTi). The sole purpose for this submission is to update the labeling for the Medtronic Anterior Cervical Plate and Fusion Systems to include MRI safety information while also providing MRI technologists with a method of concluding whether a MRI scan can be performed and specific instructions on how to perform the scan.
The provided document is a 510(k) summary for Medtronic Anterior Cervical Plate Systems, and it details the premarket notification to the FDA for updates to the labeling of these devices to include MRI safety information.
This document describes a medical device submission for a spinal implant, NOT an AI/Machine Learning-based diagnostic device. Therefore, the requested information regarding acceptance criteria, study details for AI performance (like sample size, number of experts, ground truth, MRMC studies, training set details), is not applicable to this document.
The "Performance Data" section specifically states:
"The following performance data were provided in support of substantial equivalence.
MR Safety Testing
In accordance with the FDA Guidance 'Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment' the subject Medtronic Anterior Cervical Plate Systems were evaluated for MR-safety in accordance with the following standards:
- ASTM F2052– “Standard test method for measurement of magnetically induced displacement force on passive implants in the magnetic resonance environment”
- ASTM F2213– “Standard test method for measurement of magnetically induced torque on medical devices in the magnetic resonance environment”
- ASTM F2119– “Standard test method for evaluation of MR image artifacts from passive implants”
- ASTM F2182– “Standard test method for measurement of radio frequency induced heating on or near passive implant during magnetic resonance imaging”"
This clearly indicates a focus on physical and electromagnetic compatibility testing for a medical implant, not on the performance of a software or AI algorithm.
Therefore, I cannot extract the information you requested about acceptance criteria and study data for an AI/machine learning device from this document. The document concerns the physical performance and safety of a spinal implant in an MRI environment.

2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: Not specified. The document states "mechanically tested," implying physical testing, but does not provide details on the number of devices or components tested.
- Data Provenance: The study is described as "mechanical testing" and "comparison to predicate systems and other currently marketed systems." This is laboratory-based testing, not human patient data. Therefore, questions of country of origin or retrospective/prospective are not applicable in this context.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This type of study (mechanical testing for substantial equivalence of a spinal implant) does not typically involve human "experts" establishing a clinical ground truth in the way a diagnostic AI might. The "ground truth," in this case, is defined by the objective performance standards of ASTM F1717 and the characteristics of the predicate devices. The "experts" involved would be engineering and regulatory professionals performing and analyzing the mechanical tests and comparing specifications, but their number and specific qualifications are not detailed.
4. Adjudication Method for the Test Set
Not applicable. This is not a clinical study requiring human adjudication for data interpretation. The "adjudication" is based on meeting the defined mechanical test standards and comparing physical and functional characteristics to predicate devices.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance
Not applicable. This document describes a 510(k) submission for a physical medical device (spinal implant), not an AI-powered diagnostic or assistive technology. Therefore, an MRMC study or AI assistance is not relevant.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Not applicable, as this is not an algorithm or AI device.
7. The Type of Ground Truth Used
The ground truth used for this submission is:
- Mechanical Performance Standards: Specifically, ASTM F1717 for mechanical testing.
- Predicate Device Specifications: The documented design features, materials, and intended uses of previously cleared, legally marketed spinal plate systems.
- Regulatory Definitions: The FDA's criteria for substantial equivalence under 510(k).
8. The Sample Size for the Training Set
Not applicable. This is not an AI/machine learning device that requires a training set.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this device.
