• Attributes: Therapeutic

Intended Use

The AxSOS™ Locking Plate System is intended for use in long bone fracture fixation. The system is indicated for fixation of long bone fractures including but not limited to fractures of the humerus, tibia and femur.

Device Story

AxSOS Locking Plate System is a metallic bone fixation device used for long bone fractures. This line extension adds humeral long plates (Proximal Lateral Humerus TS Long Plates) to the existing system. Plates are monoaxial, manufactured from stainless steel, and available in 6 lengths (10-20 hole configurations). Device is used by orthopedic surgeons in clinical/surgical settings to stabilize fractures. It functions as a mechanical fixation appliance to support bone healing. Output is the physical stabilization of the fracture site. Benefits include structural support for bone segments during the healing process.

Clinical Evidence

Bench testing only. Testing included static strength evaluation (combined axial and torsional loading) and fatigue strength testing (median fatigue limits and dynamic stiffness) to demonstrate equivalence to the predicate device.

Technological Characteristics

Metallic bone fixation plate; stainless steel construction; monoaxial design; 10-20 hole configurations; 6 length variants. Mechanical fixation principle. No software or electronic components.

Indications for Use

Indicated for fixation of long bone fractures, including humerus, tibia, and femur fractures, in patients requiring surgical bone fixation.

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

ﺰ

This Special 510(k) submission is a line extension to address modifications made to the AxSOSTM Locking Plate System which was cleared in K061012. This line extension is to add humeral long plates to the existing size range of the AxSOSTM Locking Plate System. These monoaxial long plates will be known as AxSOSTM Proximal Lateral Humerus TS (Threaded Shaft) Long Plates and will be available in 6 length sizes in left and right configurations.

### Intended Use

The AxSOS™ Proximal Lateral Humerus TS Long Plates line extension does not alter the intended use of the predicate AxSOS™ Locking Plate System as cleared in K061012. The indications for use for the subject plates are provided below.

### Indications

The AxSOS™ Locking Plate System is intended for use in long bone fracture fixation. The system is indicated for fixation of long bone fractures including but not limited to fractures of the humerus, tibia and femur.

# Summary of Non-Clinical Testing and Evaluation

Risk analysis was performed according to the requirements of ISO 14971:2007 "Medical Devices-Application of risk management to medical devices." Records of the risk analysis process are retained in the design history file. Testing has been performed to demonstrate equivalence of the subject device to its predicate device. The testing included static strength testing using combined axial and torsional loading as well as fatigue strength testing by way of evaluating median fatigue limits and dynamic stiffness.
