System features locking and non-locking holes; utilizes Ø4.0mm Universal Screws (fully threaded self-tapping or partially threaded). Plates incorporate polyaxial locking mechanism and holes for Kirschner wires or suture anchors. Device used by orthopedic surgeons in clinical/OR settings to stabilize fractures via compression or lag screw technique. Output is mechanical stabilization of bone segments. Benefits include restoration of alignment and support for healing in normal or osteoporotic bone. ## Clinical Evidence Bench testing only. No clinical data provided. Substantial equivalence supported by FEA and mechanical testing comparing strength of subject components to predicate devices. ## Technological Characteristics Metallic bone fixation system; includes locking/non-locking plates and screws. Features polyaxial locking mechanism. Materials are metallic (specific alloys not detailed). Components available sterile and non-sterile. Mechanical fixation via screws and Kirschner wires. ## Regulatory 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 - Numelock™ II System - Stryker® Locked Plating System - Stryker® Plating System ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Phone: (201) 831-5581 Fax: (201) 831-6038 | | Date Summary Prepared: | March 6, 2006 | ## Description This submission is a line extension to the Numelock™ II System and the Stryker® Locked Plating System for various types of locking plates, locking screws and non-locking screws. Plates will be based on the design of the monoaxial plates in the Stryker® Locked Plating System and the polyaxial locking mechanism of the Numelock 10 II plates. The subject plates have locking and non-locking holes and are used with the Ø4.0mm VariAx™ Universal Screws. There is a fully threaded, self-tapping screw and a partially threaded style of screw. All screws will be available sterile and non-sterile. The plates also have holes for standard Kirschner wires to enhance primary plate and fracture fixation or they can be used as suture anchors. Also, compression of the can be applied to the plate using the Universal Screw and act as a lag screw by pulling the bone toward the plate. ## Indications: The VariAx™ Locking Plate System is intended for use in the temporary stabilization of long bone fractures, including but not limited to: - Proximal and distal fractures including joint fractures of the humerus, tibia and other long . bones - Metaphyseal, supracondylar, peri-articular, intra-articular, intra-articular condylar fractures � - Diaphyseal fractures . - . Ankle fractures - Simple, comminuted and depression fractures . - � Non-unions and malunions - Osteotomies and bone reconstruction . - Fractures in normal or osteoporotic bone . {1}------------------------------------------------ Substantial Equivalence: The VariAx™ Locking Plate System is substantially equivalent to other plating systems in regards to intended use, design, materials, and operational principles as internal fixation components such as the Numelock™ II System, Stryker® Locked Plating System and the Stryker® Plating System. FEA and mechanical testing was conducted to compare the strength of the new plates and screws to other plates and screws on the market. The results demonstrate that the subject components are substantially equivalent in strength to the predicate components. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health and Human Services.
