Intended Use

The Locking Compression Plate System can be used for adult patients with age above 21 as indicated for fixation of fractures, including ulna, radius, humerus, femur and tibia.

Device Story

Locking compression plate system consists of titanium alloy (Ti6AI4V ELI) plates and screws; used for internal fixation of bone fractures in ulna, radius, humerus, femur, and tibia. Plates vary in length and hole count; screws vary in diameter and length. Device is non-sterile; requires hospital-based autoclave sterilization prior to use. Intended for surgical implantation by orthopedic surgeons to stabilize fractures, facilitating bone healing. Mechanical performance verified via bench testing against ASTM standards.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included compliance with ASTM F543-07 (bone screws), ASTM F382-99 (bone plates), and ASTM F897-02 (fretting corrosion).

Technological Characteristics

Materials: Titanium alloy (Ti6AI4V ELI) per ASTM F136-08e1. Components: Plates (2-18, 20, 24 holes; 44-442mm length) and screws (3.5, 5.0mm diameter; 14-120mm length). Sterilization: Autoclave (user-performed).

Indications for Use

Indicated for fixation of fractures of the ulna, radius, humerus, femur, and tibia in adult patients over 21 years of age.

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 Compression Plate (K101400)
• Locking Bone Screw (K100721)
