# Summary of Performance Data (Nonclinical and/or Clinical)

## Clinical Test

Clinical studies are not required to support substantially equivalent.

## Non-Clinical Test

- Biomechanical Test
The biomechanical tests ASTM F543 and F382 were performed to determine substantial equivalence for the Tandry CMF Plate System including the performance of plate and screw.

- Biocompatibility
Representative samples of each of the subject devices was subjected to the following: "Biocompatibility sample preparation was made according to ISO 10993-12. Biological Safety Assessment guided by ISO 10993-1. Cytotoxicity testing was performed per ISO 10993-5.

- Reprocessing and sterilization
Since the material, manufacturing process, geometry & physico-chemical, body/ fluid contact and sterilization process of the proposed device is the same as Tandry Locking Plate System K171904, the performance and testing result of the predicate can be utilized in the proposed device. The testing results support the proposed device to meet the validation requirement.

The steam sterilization instructions are validated to a sterility assurance level (SAL) of 10-6 using the biological indicator overkill method. The sterilization test is performed in accordance with ANSI/AAMI/ISO 17665-1 and ANSI/AAMI/ISO 14937. The subject device is a single-use device.

- The Tandry CMF Plate System has not been evaluated for safety and compatibility in the MR environment. It has not been tested for heating, migration, or image artifact in the MR environment. The safety of the Tandry CMF Plate System in the MR environment is unknown. Scanning a patient who has this device may result in patient injury.
