Intended Use

The IRENE Locking Compression Plate System is designed for internal fixation of bones that subject to fracture. The system includes bone plates and screws that can be used with the plate. Various sizes of plate are available for different fracture areas or clinical conditions. Bone screws are incorporated in the system and are intended to fix with plate with appropriate size. The plate has a limited-contact design. The plate system is provided unsterile. And the system is intended for single-use.

Device Story

IRENE Locking Compression Plate System consists of metallic bone plates and screws for internal fracture fixation. Plates feature limited-contact design and locking compression screw holes. System is provided non-sterile and requires moist heat sterilization by the user prior to surgery. Intended for single-use. Used by orthopedic surgeons in clinical settings to stabilize bone fractures. Output is physical fixation of bone segments, aiding healing. Benefit is structural support for fractured ulna, radius, humerus, femur, or tibia.

Clinical Evidence

No clinical data is presented in this submission. Bench testing only.

Technological Characteristics

Materials: Titanium (plate) and titanium alloy (screw). Design: Straight, tubular cross-section, limited-contact plate with locking compression holes. Energy: None (mechanical). Connectivity: None. Sterilization: Moist heat (user-performed). Standards: ASTM F382-99 (metallic bone plates), ASTM F543-13 (metallic medical bone screws).

Indications for Use

Indicated for patients age > 21 for fixation of fractures of the ulna, radius, humerus, femur, and tibia.

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.

Predicate Devices

• Locking Bone Plate (K101400)
• Locking Bone Screw (K100721)
• 3.5mm Locking Screw (K112819)
