Device Story

Internal bone fixation system consisting of metallic screws and instrumentation; used with previously cleared VariAx Plating Systems or independently via lag screw technique. Operates as mechanical fixation hardware for bone fractures, osteotomies, and revisions. Used by orthopedic surgeons in clinical settings. Provides structural stability to bone segments to facilitate healing. Available sterile and non-sterile.

Clinical Evidence

No clinical data; bench testing only.

Technological Characteristics

Metallic bone fixation screws and instrumentation. Materials and design characteristics are substantially equivalent to predicate VariAx systems. Mechanical performance verified via standardized bench testing protocols.

Indications for Use

Indicated for internal fracture fixation, osteotomies, and revision procedures (non-unions/mal-unions) in adult patients. Specific indications include compression, intra-articular, extra-articular, displaced, single, segmental, and comminuted fractures, as well as replantation, joint fusions, arthrodesis, and reconstruction in small bones (distal radius, ulna, clavicle, humerus, foot, ankle, distal tibia, fibula). Applicable to normal or osteopenic bone.

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.

#### Description

This Traditional 510(k) submission is being supplied to the U.S. FDA to provide authorization to market the VariAx 2 System. The VariAx 2 System is an internal fixation device consisting of screws and instrumentation that will be used in conjunction with previously cleared VariAx Plating Systems to treat a number of different types of fractures in the radius, ulna, humerus, clavicle, foot, and fibula. These screws can be used in conjunction with said plating systems, or in the case of non-locking screws, may also be used independently using a lag screw technique. The subject components will be available sterile and non-sterile.
