Regulatory Classification
Identification
Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.

#### Device Description
Subject of this premarket notification is an extension of the EVOS Large Fragment Plating System, the Peri-Prosthetic Plates, Blunt Tip Screws and Cable Accessories. The proposed devices incorporate design features similar to those currently incorporated on previously cleared Smith & Nephew bone plate and screw systems. Like their previously cleared counterparts. the proposed plates feature a screw-to-plate locking feature that permits their use with the previously cleared and compatibility designed locking and non-locking screws described in this premarket notification. EVOS Large Fragment Per-Prosthetic Plates are available in a variety of plate designs for specific anatomical areas. These plate designs have a combination of 3.5mm and 4.5mm holes. Plate designs may include threaded holes, non-threaded holes, and variable-angle locking holes. Blunt Tip Screws are available in 4.5mm diameter and are identical to the EVOS 4.5mm Cortex Locking Screws described in K201918 with the exception of the blunt tip. Cable Accessories include 3.5mm and 4.5mm cable saddles and 3.5mm cable post.
## Indications for Use
The EVOS Large Fragment Plating System is indicated for adult patients. It is indicated for fixation of long bone fractures.
#### Technological Characteristics
Device comparisons described in this premarket notification demonstrated that the proposed devices are substantially equivalent to legally marketed predicates with respect to intended use, indications, and performance characteristics. The subject devices include plates with both locking and non-locking holes. Locking holes in the plates can either be threaded holes or variable angle holes and non-locking holes are not threaded. The holes are identical to those used in the EVOS Large Fragment Plates cleared via K201918. The subject screws feature a hex drive and are identical to existing Smith & Nephew predicate screws with respect to threadform and major and minor diameter.
## Summary of Pre-Clinical Testing
- Finite element analysis (FEA) was conducted on the proposed plate designs to determine the worst case plates for further mechanical testing. Plates were separated into groups for evaluation based upon similar designs or anatomical application.
- Fatigue performance was evaluated through four point bending fatigue or construct fatigue testing for the worst case plate designs identified through FEA. Results of the testing determined that the subject plates performed similar or superior to the predicate plates tested, when evaluated under the same conditions.
- Magnetic resonance imaging (MRI) compatibility testing was conducted as per the FDA's ● guidance "Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment", December 11, 2014.
- . Packaging verification testing was conducted for the proposed packaging configurations and the results of this testing demonstrated that the product will not be damaged during shipment and will adequately maintain sterility post shipment.
- . Bacterial endotoxin testing was completed and met the acceptable endotoxin limits as stated in the FDA Guidance, "Submission and Review of Sterility Information in Premarket Notification (510(k)) Submissions for Devices Labeled as Sterile," "Pyrogen and Endotoxins Testing: Questions and Answers," and ANSI/AAMI ST72.

# Conclusion
This Traditional 510(k) premarket notification is being submitted to request clearance for the EVOS Large Fracture Plating System Peri-Prosthetic. Based on similarities to the predicate plating systems and a review of the mechanical testing performed, the subject devices are substantially equivalent to the predicate devices.
