The Subject Device screws will have the same clinical application, treat the same craniomaxillofacial anatomical locations, and are for the same patient population as the corresponding Predicate/Reference Devices.
The provided FDA 510(k) clearance letter pertains to Stryker MP, Mandible, HMMF and MMF AXS Screws, which are intraosseous fixation screws. This submission is for a medical device (screws), not an AI/software as a medical device (SaMD). Therefore, the questions related to AI device performance, sample sizes for test/training sets, expert ground truth, adjudication methods, MRMC studies, or standalone algorithm performance are not applicable to this document.
The clearance is based on demonstrating substantial equivalence to predicate devices, primarily through engineering performance bench testing.
Here's the relevant information that can be extracted from the document:
1. A table of acceptance criteria and the reported device performance
The document states that "The Subject Device met all pre-defined acceptance criteria, and the results of the V&V tests support the substantial equivalence of the Subject Device to the Predicate/Reference Devices." However, the specific numerical acceptance criteria for each test are not detailed in this summary document. The document lists the types of performance bench tests conducted:
| Test Name | Reported Device Performance (as stated in document summary) |
|---|---|
| Pull-out Test per ASTM F543 | Met all pre-defined acceptance criteria, supporting substantial equivalence to Predicate/Reference Devices. |
| Full Insertion and Removal Test per ASTM F543 | Met all pre-defined acceptance criteria, supporting substantial equivalence to Predicate/Reference Devices. |
| Shaft Shear Test per ASTM F543 | Met all pre-defined acceptance criteria, supporting substantial equivalence to Predicate/Reference Devices. |
| Head Shear Test | Met all pre-defined acceptance criteria, supporting substantial equivalence to Predicate/Reference Devices. |
| Locking Cantilever Bending Test | Met all pre-defined acceptance criteria, supporting substantial equivalence to Predicate/Reference Devices. |
| Locking Torque to Failure Test | Met all pre-defined acceptance criteria, supporting substantial equivalence to Predicate/Reference Devices. |
| Self-Retention Test | Met all pre-defined acceptance criteria, supporting substantial equivalence to Predicate/Reference Devices. |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This information is not provided in the summary document. The document refers to "Verification and Validation (V&V) testing" and "test reports" being included within the full submission, but the summary itself does not detail specific sample sizes for these bench tests or the provenance of any data beyond the general statement that testing was performed.
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 is a medical device (screws) and does not involve AI or software requiring expert review for ground truth establishment. The "acceptance criteria" are engineering performance metrics.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not Applicable. This is a medical device (screws) and does not involve subjective human interpretation or adjudication for its performance evaluation in the way an AI diagnostic tool would. Performance is based on objective engineering tests.
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 medical device (screws) and does not involve AI or human "readers."
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not Applicable. This is a medical device (screws) and does not involve an algorithm.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
For mechanical performance tests, the "ground truth" or reference standard would be the physical properties and behavior of the devices as measured by standardized testing methods (e.g., ASTM F543) and compared against pre-defined engineering specifications and the performance of the predicate device.
8. The sample size for the training set
Not Applicable. This is a medical device (screws) and does not involve a training set as would be used for AI/machine learning.
9. How the ground truth for the training set was established
Not Applicable. This is a medical device (screws) and does not involve a training set.

VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE [§807.92(a)(6)]
The Subject Device is compared to its Predicate/Reference Devices for substantial equivalence of technological characteristics based on the following criteria:
A. Principles of Operation
B. Technological Characteristics
A. Principles of Operation / Operating Principle
The basic operating principle of the Subject Device Stryker MP AXS Screws and Mandible AXS Screws, and the corresponding Reference Device MP Screws and Mandible Screws is to stabilize or rigidly fixate bone during osteotomy for fractures and reconstruction using plates and screws.
The basic operational principle of the Subject Device HMMF AXS Screws and MMF AXS Screws, and the corresponding Predicate/Reference Device HMMF Screws and MMF Screws is to temporarily stabilize the maxilla and mandible in the correct occlusal relationship. The functionality of the device remains the same from Predicate/Reference to Subject Device.
The fundamental scientific technology of the Subject Device has not changed. This is because the principle of operation, the mechanism of action, the intended use, and the materials of construction have not changed as a result of the device modification.
The Subject Device screws consist of a threaded shaft for insertion and anchoring of the device into the bone. The Subject Device screw head interfaces with the corresponding AXS screwdriver blade to deliver the screw to the operating site and transmission of the rotational forces required for insertion. The mechanism of action of the modified Subject Device screws remains unchanged and is the same as the Predicate/Reference Device.
B. Technological Characteristics
Even with the modifications to the Subject Devices described in this Traditional 510(k), the technological characteristics remain the same as the corresponding Predicate/Reference Devices:
- Same operating principle
- Same mode of fixation
- Same area of contact and contact duration
- Same material
