Indications for Use

The EVOS Small Fragment Plating System is indicated for adult and pediatric patients with osteopenic bone. It is indicated for fixation of small and long bone fractures, including, but not limited to, those of the tibia, fibula, femur, humerus, ulna, radius, pelvis, acetabulum, metacarpals, metatarsals, and clavicle. The EVOS Partial Articular and Anti-Glide plates are indicated for the treatment of partial articular fractures of the distal and proximal tibia (AO/OTA Fracture Classification Type B), and for fracture fixation of the fibula.

Device Story

EVOS Small Fragment Lower Extremity Plates are metallic bone fixation implants designed for surgical fracture stabilization. The system includes various plate geometries featuring 2.7mm and 3.5mm holes, including threaded, non-threaded, and variable-angle locking configurations, available in 'thick' and 'thin' profiles. Used by orthopedic surgeons in clinical/OR settings, these plates provide mechanical support to bone fragments to facilitate healing. The device is implanted via standard orthopedic surgical techniques. The system shares compatible instruments and implants with existing Smith & Nephew EVOS MINI and Small Fragment systems. Clinical benefit is derived from stable internal fixation of fractures, promoting bone union and patient mobility.

Clinical Evidence

Bench testing only. Evidence includes finite element analysis (FEA) to identify worst-case designs, followed by static and cantilever bend testing to evaluate mechanical performance against predicate devices. Packaging verification testing confirmed sterility maintenance and shipping durability. Bacterial endotoxin testing confirmed compliance with ANSI/AAMI ST72 limits. No clinical data was provided.

Technological Characteristics

Metallic bone fixation plates featuring 2.7mm and 3.5mm holes (threaded, non-threaded, variable-angle locking). Available in 'thick' and 'thin' varieties. Mechanical performance validated via FEA and static/cantilever bend testing. Sterility maintained via validated packaging configurations; endotoxin levels compliant with ANSI/AAMI ST72.

Indications for Use

Indicated for adult and pediatric patients, including those with osteopenic bone, requiring fixation of small and long bone fractures (tibia, fibula, femur, humerus, ulna, radius, pelvis, acetabulum, metacarpals, metatarsals, clavicle). Partial Articular and Anti-Glide plates specifically indicated for distal/proximal tibia partial articular fractures (AO/OTA Type B) and fibula fracture fixation.

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 Small Fragment Plating System, the EVOS Small Fragment Lower Extremity Plates. The subject plates feature similarities to existing Smith & Nephew small fragment plates (TC-100 Small Bone Plating System, PERI-LOC and PERI-LOC VLP Plating Systems, EVOS Small Fragment Plating System Straight Plates) and also share some instruments and compatible implants from the existing EVOS MINI Plating System and EVOS Small Fragment Plating System. EVOS Small Fragment Lower Extremity Plates are available in a variety of plate designs for specific anatomical areas. These plate designs include plates with 2.7mm holes or 3.5mm holes only, or with a combination of 2.7mm and 3.5mm holes. Plate designs may include threaded holes, nonthreaded holes, and variable-angle locking holes. The subject plates are offered in "thick" and "thin" varieties. The "thin" plates are the partial articular/antiglide plates.

### Indications for Use

The EVOS Small Fragment Plating System is indicated for adult and pediatric patients, as well as patients with osteopenic bone. It is indicated for fixation of small and long bone fractures, including, but not limited to, those of the tibia, fibula, femur, humerus, ulna, radius, pelvis, acetabulum, metacarpals, metatarsals, and clavicle.

The EVOS Partial Articular and Anti-Glide plates are indicated for the treatment of partial articular fractures of the distal and proximal tibia (AO/OTA Fracture Classification Type B), and for fracture fixation of the fibula.

## 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, identical to the holes used in the EVOS Small Fragment Straight Plates cleared via K162078.

## 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.
- Bending performance was evaluated through static or cantilever bend 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.
- . 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.

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

- 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 Small Fragment Plating System Lower Extremity Plates. 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.
