Intended Use

Locking Bone Plates and Screws are intended for adult patients with age above 21 as indicated for fixation of fractures, including ulna, radius, humerus, femur and tibia.

Device Story

System consists of metallic locking bone plates, locking screws, and associated surgical instruments. Plates and screws provide internal fixation for bone fractures. Screws are available in self-tapping and self-drilling configurations. Devices are provided non-sterile; intended for sterilization via hospital autoclave prior to use. Used by surgeons in clinical/surgical settings to stabilize bone fractures, facilitating healing through rigid fixation.

Clinical Evidence

Bench testing only. Compliance with ASTM F382-99 (bone plates) and ASTM F543-07 (bone screws) demonstrated mechanical performance equivalent to predicates. Sterilization validation performed per ANSI/AAMI/ISO 17665-1.

Technological Characteristics

Materials: Titanium (ASTM F67-06) for plates; Ti6Al4V ELI (ASTM F136) for screws. Mechanical principle: Locking fixation. Sterilization: Moist heat (autoclave) to SAL 10^-6. Plate specs: 2-24 holes, 26-312mm length. Screw diameters: 3.5, 4.5, 5.0mm.

Indications for Use

Indicated for adult patients >21 years old requiring internal 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 Compression Plate (K101400)
• Locking Bone Screw (K100721)
