This document describes a 510(k) premarket notification for several Zimmer Spine Anterior Cervical and Lumbar Plate Systems. The purpose of this submission is not to introduce a new device or change the design/performance of existing devices, but solely to update the product-specific package inserts (Instructions for Use - IFU) with MRI Conditional language. Therefore, the "acceptance criteria" and "study that proves the device meets the acceptance criteria" are related to MRI compatibility, rather than the primary biomechanical function of the implants.
Here's an analysis based on the provided text, addressing your points:
1. A table of acceptance criteria and the reported device performance
The acceptance criteria here are implicitly meeting the standards for MRI compatibility for passive implants. The reported performance is that the devices were tested according to these standards and found to be MRI Conditional.
Acceptance Criteria (Implied) | Reported Device Performance |
---|---|
Magnetically Induced Displacement Force: Devices should not exhibit significant displacement when exposed to MR environments. | Tested per ASTM F2052: 2006. (Details on exact thresholds and results are not provided in this summary document, but the fact it passed for an update with MRI Conditional language implies it met the criteria.) |
Magnetic Resonance (MR) Image Artifacts: Devices should not create excessive artifacts that obscure diagnostic information. | Tested per ASTM F2119: 2007. (Similarly, details on artifact size/severity not provided, but passed for MRI Conditional IFU.) |
Radio Frequency (RF) Induced Heating: Devices should not experience unsafe levels of heating during MRI. | Tested per ASTM F2182: 11a*. (Details on heating levels and safe limits not provided.) |
Magnetically Induced Torque: Devices should not experience significant torque when exposed to MR environments. | Tested per ASTM F2213: 2006. (Details not provided.) |
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: The document does not specify the exact number of devices (plates and screws) tested for each MRI compatibility standard. It refers to "Plate implants contained in the Zimmer Spine Anterior Cervical and Lumbar Plate Systems were assessed and tested." This suggests representative samples were used for each type of implant.
- Data Provenance: Not explicitly stated, but typically, such testing is conducted in controlled laboratory environments in the country of manufacturing or a certified testing facility. The context is a US FDA submission, so the testing would have been to US-recognized standards. The testing is prospective in nature, as it's a specific set of tests performed on the physical devices for this submission.
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)
This question is not applicable to this submission. The "ground truth" here is the physical interaction of the medical devices with magnetic fields, measured by engineering and physics principles, not by expert interpretation of clinical data or images. The standards (ASTM) themselves define the methodology and acceptable limits, which are established by relevant technical experts in the field of MRI safety and medical devices.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. This is not a clinical study involving human assessment of outcomes or images. The results of the MRI compatibility tests are objective measurements against defined ASTM standards.
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 submission is for MRI conditional labeling updates for orthopedic spinal implants, not for an AI/CAD device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This submission is for MRI conditional labeling updates for orthopedic spinal implants, not for an AI/CAD device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" used for this submission is based on scientific and engineering principles outlined in the referenced ASTM standards for MRI compatibility testing. These standards define the acceptable limits for magnetically induced displacement, torque, heating, and image artifact generation for passive medical implants.
8. The sample size for the training set
Not applicable. This submission is for MRI conditional labeling updates for existing devices, not for a device developed using a training/test set methodology (e.g., AI/ML).
9. How the ground truth for the training set was established
Not applicable. See point 8.

The provided documentation focuses on a 510(k) summary for the Zimmer Spine Trinica® Anterior Lumbar Plate System, which is a medical device for spinal fixation. This type of submission typically demonstrates substantial equivalence to a predicate device rather than presenting a performance study with acceptance criteria in the way a diagnostic AI/ML device would.
Therefore, the requested information regarding acceptance criteria, study details (sample size, data provenance, expert adjudication, MRMC study, standalone performance), and ground truth establishment is not applicable to this document. The document describes a sterilization validation as the primary "performance testing" conducted.
Here's a breakdown of the applicable information:
1. A table of acceptance criteria and the reported device performance:
Acceptance Criteria | Reported Device Performance |
---|---|
Device meets design controls for sterilization. | Sterilization testing of the components/instruments contained in the subject Trinica ALPS tray was conducted. The test results demonstrated the modified device met the requirements of ISO 17665 and AAMI TIR12. |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- Not Applicable. The submission does not detail a "test set" for a performance study in the context of diagnostic accuracy. The performance testing was related to sterilization validation.
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. Ground truth, in the context of expert review, is not relevant to sterilization validation.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

This document describes a 510(k) summary for the Zimmer Spine Trinica Anterior Lumbar Plate System. It focuses on demonstrating substantial equivalence to predicate devices rather than providing detailed acceptance criteria and performance study results as one might find for a novel AI/software medical device.
Therefore, many of the requested categories for a study proving device meets acceptance criteria are not applicable or cannot be extracted from this specific document.
Here's an analysis based on the provided text:
Acceptance Criteria and Device Performance (Not Applicable - Substantial Equivalence Claim)
This 510(k) submission does not establish or report performance against specific quantitative acceptance criteria for a novel device. Instead, it claims substantial equivalence to existing predicate devices. The "acceptance criteria" in this context are implicitly that the device's technological characteristics and intended use are similar enough to existing legally marketed devices, such as the Synthes Anterior Tension Band (ATB) System and DePuy Spine AEGIS Anterior Lumbar Plate System.
The "device performance" is therefore not demonstrated through a study with outcome metrics but rather by stating that its characteristics (materials, range of sizes, intended use) are similar to the predicates.
Acceptance Criteria (Implicit) | Reported Device Performance (Claimed Equivalence) |
---|---|
Substantial Equivalence: Device must have the same technological characteristics (materials, sizes, intended use) as predicate devices. | "The Zimmer Spine Trinica Anterior Lumbar Plate System shares the same technological characteristics as the Synthes Anterior Tension Band (ATB) System and the Depuy Spine's AEGIS Anterior Lumbar Plate System. These characteristic include materials, range of sizes, and intended use." "The Zimmer Spine Trinica Anterior Lumbar Plate System is substantially equivalent to the Synthes Anterior (ATB) System and the Depuy Spine's AEGIS Anterior Lumbar Plate System in design, materials, function and intended use." |

Summary of the K061353 Filing:
The Zimmer Spine Trinica Anterior Lumbar Plate System is a temporary supplemental fixation device for the spine. The 510(k) submission (K061353) asserts its substantial equivalence to two predicate devices: the Synthes Anterior Tension Band (ATB) System and the DePuy Spine AEGIS Anterior Lumbar Plate System. The basis for this claim is the similarity in design, materials (Titanium alloy Ti-6Al-4V), functional aspects ("locked into a variety of configurations," "anti-migration locking caps"), range of sizes, and intended use as a spinal fixation system to treat L1-S1 instability resulting from conditions like fracture, tumor, degenerative disc disease, etc. The FDA's review led to a determination of substantial equivalence, allowing the device to be marketed. This type of submission relies on demonstrating that the new device does not raise new questions of safety and effectiveness compared to a legally marketed predicate.
