### SUBJECT DEVICE DESCRIPTION IV.

The subject devices include the Stryker Customized Mandible Recon Plate (CMRP) and Stryker Surgeon iD Mandible Recon Plate (SMRP). Both CMRP and SMRP are intended to be used for rigid internal fixation of primary, secondary mandibular reconstructions, and fixation of mandibular fractures; and have an indication for use in primary mandibular reconstruction with bone graft, temporary bridging until delayed secondary reconstruction, secondary mandibular reconstruction, and mandibular fracture fixation. Subject devices have similar intended use and technical characteristics as the primary predicate device (K193136) and the reference device (K190696), and the additional language in indications for use statement is supported by the reference device (K014263).

The subject devices' plate(s) are designed and manufactured for one patient and/or surgeon specifically, and the customized patient-specific and surgeon-specific design of the plate(s) allows certain features to be configured to meet the individual needs of each patient and surgeon. The subject devices' plate has additional design configuration options (such as branches and flanges, and updated plate bar widths of 5.75-7.5mm) when compared to the primary predicate device. The subject devices' plate(s) are provided with the Design Proposal document, an Instruction for Use (IFU), and an optional Anatomical Model. Additionally, the subject device is compatible with a separately provided Surgical Guides accessory.

### INDICATIONS FOR USE V.

| Table 1: Comparison of Indication for Use. | | |
|--------------------------------------------|--|--|
|--------------------------------------------|--|--|

{5}------------------------------------------------

The subject device's indication for use statement is similar to the primary predicate device but with the addition of the fracture fixation of the mandible, which is supported by the reference device K014263. The reference device K190696 is also identified for similar reasons as the primary predicate, to support SMRP device. Therefore, substantial equivalence is shown between the subject devices and predicate devices.

### VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

The subject devices are the Stryker Customized Mandible Recon Plate and Surgeon iD Mandible Recon Plate based on the following criteria:

- A. Principle of Operation
- B. Technological Characteristics

# A. Principle of Operation

The basic operational principle of the Stryker Customized Mandible Recon Plate and Surgeon iD Mandible Recon Plate is the stabilization, reconstruction, and/or bridging of mandible reconstruction and fracture fixation.

# B. Technological Characteristics

The technological characteristics of the subject devices is similar to their previously cleared technological characteristics, but with additional design configuration options (such as branches and flanges, updated plate bar widths (5.75mm-7.5mm), and transition radius (1.6mm)). Stryker Customized and Surgeon iD Mandible Recon Plates is for the reconstruction or bridging of mandible resection, and area of the application is mandible.

Additionally, the subject devices include updated intended use/indications for use to incorporate fracture fixation of mandibles, updated design feature configuration, and updated IFUs (Instruction for Use).

The subject devices' intended use and indications for use is similar to the primary predicate device (K193136) and the reference device (K190696), and the additional language in indications for use statement is supported by the reference device (K014263). Subsequently, the subject devices' IFU has been updated to reflect these changes.

The incorporated design feature configurations contain branches and flanges to increase design flexibility. Branches are normal bars with screw holes that branch off the normal plate line and offer a greater variety to fixate the bone fragments. Flanges are bars that close out without a screw hole at the end of the bar. These flanges branch off the plate to wrap around the bone to increase the plate fit. The new design envelope is presented in Table 1.

| Table 1: Design envelope | |
|--------------------------|--------------------------------------|
| Plate Material | Commercially pure titanium (grade 2) |
| Type of design | Customized |
| # Of screw holes | 4-35 (variable) |
| Ranges of shapes | Hemi and full, branches, flanges |
| Screw systems | 2.0, 2.3 mm, 2.7mm |
| Plate profile height | 2.0 mm and 2.8 mm |
| Bar width | 5.75 mm – 7.5 mm |

### VII. PERFORMANCE DATA

The following performance testing was done to show substantial equivalence:

The subject devices' cleaning, and sterilization are same as previously cleared devices as demonstrated within the submission. Therefore, new testing and validation for cleaning, and sterilization are not required to prove substantial equivalency to the predicate device.

The proposed modifications for the subject devices have been assessed and validated to show their safety and effectiveness. The below testing and assessment were done to support substantial equivalence of the subject devices to the predicate device.

- Biocompatibility Assessment according to ISO 10993-1. ●
- . Mechanical strength testing
- End User Validation ●

### Performance Bench Testing

As stated above, mechanical strength testing was performed on the subject device plate(s).

All tests had been performed with the corresponding worst case design for the new design envelope and design features (branches and flanges) subject to this submission. For the biomechanical tests, all new design options incorporated a screw hole to bar connection. The entire mechanical stress concentrated to the screw hole representing the worst case. This was tested in 4-point bending and cantilever bending tests. The tests were performed according to the standards ASTM F382 and ASTM STP 731.

The mechanical strength testing results were included within this submission. The subject devices met all pre-defined acceptance criteria, and the results of the tests support the substantial equivalence of the subject devices to the predicate device.

The End User Validation was performed as a simulated use in a Cadaver Lab, where surgeons performed the surgery in a realistic scenario. Validation by skilled users demonstrated that the user needs / design inputs were met for the subject devices.

### Animal Testing

Animal testing was not required as a basis for substantial equivalence.

### Clinical Testing

Clinical testing was not required as a basis for substantial equivalence.

### VIII. CONCLUSIONS

The results of the performance testing provided in this submission demonstrate the subject devices, Stryker Customized Mandible Recon Plate and Stryker Surgeon iD Mandible Recon Plate, perform as intended in the specified use conditions. According to the comparison based on the requirements of 21 CFR 807.92 and the information provided herein, it is concluded that the information included in this submission supports substantial equivalence.
