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.

# Intended Use/Indications for Use
21 CFR 807.92(a)(5)

Montblanc Radius Plate System

The Montblanc Radius Plate System is intended for internal fixation for fractures and reconstruction of the small bones, primarily including the distal radius and distal ulna. Examples of these internal fixations and reconstructions include compression fractures, intra-articular and extra-articular fractures, displaced fractures, osteotomies, non-unions and malunions. This system can be used for palmar, dorsal or orthogonal application.

{5}

Montblanc Ankle Plate System
The Montblanc Ankle Plate System is intended to be used for internal bone fixation for bone fractures, fusions, osteotomies and non-unions in the distal tibia and fibula.

## Indications for Use Comparison
**21 CFR 807.92(a)(5)**

Montblanc Plate System is substantially equivalent to the predicate devices cleared under K222267, Arthrex 2.4 mm Volar Distal Radius Plate System and K123241, Arthrex Fracture Plates in which the basic design features, intended use, fundamental scientific technology, materials and sterility (non-sterile) are identical.

## Technological Comparison
**21 CFR 807.92(a)(6)**

The subject device is substantially equivalent to the primary predicate device with respect to indication for use, product code, sterilization method, anatomical site of use, materials and standards to which the materials conform, hole dimension, locking mechanism, screw placement trajectory and compatible screw sizes and types. There's slight difference with the design between the subject device and predicate device, number holes, plate width range, plate length range and plate thickness range but these differences are slight and do not raise any risks in the safety and effectiveness of the subject device.

ARIX Wrist System (K151468), Arix Ankle System (K193616), ARIX Ankle Fibula Hook Plate System (K170979) were referred to the reference devices to support the appropriate scientific methods for the characterization of anodization coating (Type II, AMS 2487) on the subject device. Subject device has the identical anodization process compared to a previously cleared reference devices (K151468, K193616, K170979).

Therefore, we conclude that the different characteristics do not raise different questions of safety and effectiveness, and thus the subject device is substantially equivalent to the predicate device.

## Non-Clinical and/or Clinical Tests Summary & Conclusions
**21 CFR 807.92(b)**

General Tests were conducted as the Visual, Dimension and Mechanical Properties Test were conducted in accordance with characteristic of finished product to ensure indication for use. The performance test was implemented according to manufacturer SOP, FDA guidance Orthopedic Fracture Fixation Plates - Performance Criteria for Safety and Performance Based Pathway (Guidance for Industry and Food and Drug Administration Staff (Document issued on April 11, 2022.), ASTM F382, ASTM F543.

Plates with the smallest cross-sectional area of the critical region of the device were chosen as the worst-case sample for Minimum bending strength (N-m), Minimum bending structural stiffness (N-m2). Screws with the smallest cross-sectional area of the critical region of the device and longest length were chosen as the worst-case sample for Torsional Strength Test (N-m), Driving Torque (insertion/removal torque testing) (N-m). Screws with the smallest cross-sectional area of the critical region of the device and shortest length were chosen as the worst-case sample for Axial Pullout Strength (N).

We believe that the performance test acceptance criteria is appropriate and that each test result ensure the effectiveness of Montblanc Plate System for the indications for use provided by the manufacturer and supports substantial equivalence.
