The Stryker® Leibinger Universal CMF and Universal 2.0 Mini Plating Systems are Craniomaxillofacial (CMF) plate and screw systems intended for osteotomy, stabilization of CMF fractures and reconstruction.
The MP LeFort I Plates as part of the predicate subgroup Universal 2.0 Mini Plating System are implants indicated for osteotomy stabilization and rigid fixation of LeFort I fractures of the maxillofacial skeleton.
The LeFort I Plates, which were cleared as part of the overall plate system in K022185, have been modified for use with 2.0 mm screws, more flexible applications, and in-between advancements for stabilizing osteotomies. The proposed modifications to the LeFort I Plates comprise a dimensional design modification for maxillofacial use only. There have been no modifications to the screws, meshes/plates, screwdriver blades, or other accessory devices.
The provided text describes a 510(k) premarket notification for a medical device called "MP LeFort I Plates." This submission aims to demonstrate substantial equivalence to a predicate device, as opposed to providing detailed performance data against specific acceptance criteria for a novel device.
Therefore, the document does not contain the information needed to fill out the table regarding acceptance criteria and reported device performance, nor does it describe a study proving the device meets those criteria in the way one might expect for a new, AI/software-driven medical device.
Specifically, the document states:
- "Biocompatibility and sterility testing was not required as a basis for substantial equivalence."
- "The results of the performance bench tests support the proposed substantial equivalence of the subject device."
- "It is concluded that the information included in this submission supports substantial equivalence."
This indicates that the focus of this submission is on demonstrating that the modified device is as safe and effective as a legally marketed predicate device, rather than proving performance against novel acceptance criteria for a device like an AI algorithm.
Based on the provided text, I cannot describe acceptance criteria or a study that proves the device meets them because the document focuses on demonstrating substantial equivalence through bench testing and material comparisons, not on establishing and meeting new performance thresholds for a device like an AI algorithm.
If this were a submission for an AI/software device, the "Performance Bench Testing" section (VIII) would contain details like the acceptance criteria, metrics, sample sizes, and ground truth establishment methods. However, for this physical bone plate device, it simply lists "Analysis of functional interfaces" and "Fatigue Test" to support substantial equivalence, without detailing specific thresholds or the type of study typically associated with AI performance validation.

III. PREDICATE DEVICE [§807.92(a)(3)]
Universal CMF System - K022185
The predicate Universal CMF System, which was cleared in K022185, is intended for osteotomy, stabilization, and rigid fixation of CMF fractures and reconstruction. The Universal CMF System consists of an implant module for the respective anatomical and indicated areas with each containing various screw and plate versions and shapes.
DEVICE DESCRIPTION [§807.92(a)(4)] IV.
The LeFort I Plates, which were cleared as part of the overall plate system in K022185, have been modified for use with 2.0 mm screws, more flexible applications, and in-between advancements for stabilizing osteotomies. The proposed modifications to the LeFort I Plates comprise a dimensional design modification for maxillofacial use only. There have been no modifications to the screws, meshes/plates, screwdriver blades, or other accessory devices.
V. INDICATIONS FOR USE
The Stryker® Leibinger Universal CMF and its subgroup Universal 2.0 Mini Plating Systems are cranio-maxillofacial (CMF) plate and screw systems intended for osteotomy, stabilization, and rigid fixation of CMF fractures and reconstruction.
The MP LeFort I Plates as part of the predicate subgroup Universal 2.0 Mini Plating System are implants indicated for osteotomy, stabilization, and rigid fixation of LeFort I fractures of the maxillofacial skeleton.
COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE VI. PREDICATE DEVICE
The modified Universal CMF System is compared to its predicate device for substantial equivalence of technological characteristics based on the following criteria:
- A. Principle of Operation
- B. Technological Characteristics
{6}------------------------------------------------
A. Principle of Operation
The basic operational principle of the Universal CMF System remains the same: The operating principle for the Universal CMF System is to stabilize and provide rigid fixation of fractures and reconstruction.
B. Technological Characteristics
The dimensional modification described in this special 510(k) is to the MP LeFort I Plates in the Universal CMF System. However, these modifications do not alter the technological and operational characteristics of the plates in the Universal CMF System. The technological characteristics remain the same:
- Same operating principle: Fracture and osteotomy fixation of small bones -
- Same mechanism of action: The plates consist of two screw hole segments that are in । parallel to each other with a defined distance to treat fractures and osteotomies advancing the maxilla
- -Same construction materials: The subject MP LeFort I Plates are manufactured out of the same material (Titanium Grade 2, ASTM F67) as the predicate device.
- -Compatibility of the modified plates with the previously cleared screws and other accessories from K022185 is identical to previously cleared devices of the 2.0 mm module
VII. STERILIZATION VALIDATION AND SHELF-LIFE
The modified plates will be provided non-sterile like the predicate devices. There has been no change in the material or design of the products that impacts end user reprocessing. The subject device is offered to the end users as part of the predicate Universal CMF System, which includes the modules for storage of the implants and different instruments needed for surgery. Therefore, due to the high number of different components, the complete system needs to be steam sterilized at an extended cycle of 6 minutes at 132°C to ensure a sterility level of SAL 10-6. As it is common practice within hospitals to sterilize all parts of the Universal CMF System together, the extended cycle is indicated in the Instructions for Use for all of the implants stored in the modules, and, therefore, also for the subject device even if single implants themselves can be steam sterilized within 4 minutes at 132°C as recommended in Appendix C of the FDA Guidance document for Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling.
A sterilization reference predicate was identified and tested in a storage module with a cycle of 4 minutes at 132°C, and the storage module was also part of the sterilization validation of the whole system. During the sterilization analysis it was found the subject devices are covered by the representative sterilization reference predicate that was tested through

Attachment 14.2 Sterilization Validation Report and cleared under K014263. Please see Section 14 for additional details.
VIII. PERFORMANCE DATA
Based on the Risk Analysis performed on the modifications to the MP LeFort I Plates in the Universal CMF System, bench testing was performed in support of the substantial equivalence determination.
Biocompatibility and sterility testing was not required as a basis for substantial equivalence. There is no change in the material, manufacturing process, duration or location of contact, or reprocessing methods.
Performance Bench Testing
The following performance bench tests were completed.
- Analysis of functional interfaces -
- -Fatigue Test
Overall, the results of the performance bench tests support the proposed substantial equivalence of the subject device.
IX. CONCLUSIONS
The results of the non-clinical data demonstrate that the modified MP LeFort I Plates will perform as intended in the specified use conditions. According to the comparison based on the requirements of 21 CFR 807.87 and the information provided herein, it is concluded that the information included in this submission supports substantial equivalence.
