• Submission Type: Traditional
• Regulation: 21 CFR 888.3030
• Device Class: Class 2
• Attributes: Therapeutic, Pediatric

Intended Use

The Merete Locking Bone Plate System III can be used for adult and pediatric patients. Indications for use include fixation of fresh fractures, revision procedures, joint fusion, and reconstruction of small bones of the hand, feet, wrist, ankles, fingers and toes.

Device Story

System consists of contoured, anatomically shaped locking bone plates, locking screws (3.0 mm and 3.5 mm), and cannulated compression screws (3.0 mm). K-wires used for temporary fixation. Device used by surgeons in clinical settings for internal bone fixation. Plates and screws provide mechanical stabilization of bone segments to facilitate healing in fractures, fusions, or reconstructions. Benefit is restoration of skeletal alignment and stability.

Clinical Evidence

Bench testing only. No clinical data provided. Mechanical testing included dynamic 4-point bending fatigue tests and screw torsion tests conducted per ASTM and ISO standards to demonstrate structural integrity.

Technological Characteristics

Materials: Ti-6Al-4V ELI Alloy (ASTM F136, ISO 5832-3) for plates, screws, and K-wires; CrNiMo Stainless Steel (ASTM F138, ISO 5832-1) for K-wires. System includes contoured locking plates, locking screws, and cannulated compression screws. Mechanical fixation principle. Non-powered, passive implantable device.

Indications for Use

Indicated for adult and pediatric patients requiring fixation of fresh fractures, revision procedures, joint fusion, and reconstruction of small bones of the hand, feet, wrist, ankles, fingers, and toes.

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:

The Merete Locking Bone Plate System III consists of contoured, anatomically shaped locking bone plates in various sizes and different curvatures for the fixation with Merete 3.0 and 3.5 mm locking screws and 3.0 mm cannulated compression screws. Before placing the screws, plates can be fixed temporarily with K-Wires.

Plates, screws and K-Wires of the Merete Locking Bone Plate System III are made of Ti-6Al-4V ELI Alloy for Surgical Implant Applications (ASTM F136, ISO 5832-3). K-Wires are additionally made of CrNiMo Stainless Steel for Surgical Implants (ASTM F138, ISO 5832-1).

#### Intended use:

The Merete Locking Bone Plate System III can be used for adult and pediatric patients. Indications for use include fixation of fresh fractures, revision procedures, joint fusion, and reconstruction of small bones of the hand, feet, wrist, ankles, fingers and toes.

### Technological Characteristics:

The components of Merete Locking Bone Plate System III are similar to legally marketed predicate devices listed above in that they share similar indications of use, are manufactured from similar materials and incorporate similar technological characteristics.

### Potential risks:

The risks associated with this device are the same as with any metallic internal fixation device. These include but not limited to the following: Delayed or nonunion which may lead to breakage of the implant. Bending or fracture of the implant, metal sensitivity, or allergic reaction to a foreign body. Pain, discomfort, or abnormal sensation due to the presence of the device.

#### Mechanical testing:

In order to demonstrate that the Merete Locking Bone Plate System III has the mechanical properties necessary to perform its intended use and that the device performs as well as or better than the predicate devices, Merete has conducted nonclinical mechanical testing. This includes:

- Dynamic 4-point bending fatigue test (per ASTM F382-2003 and ISO 9585) .
- Screw torsion test (per ASTM F543 and ISO 6475) .
- Engineering rationale .

All tests considered the worst case scenario for the system and were passed successfully.
