Intended Use

The ExsoMed INnate Cannulated Screw System is intended for fixation of intra-articular and extra-articular fractures and non-unions of small bones and small bone fragments; arthrodesis of small joints; bunionectomies and osteotomies, including scaphoid and other carpal bones, metacarpals, tarsals, metatarsals, patella, ulnar styloid, capitellum, radial head and radial styloid.

Device Story

INnate Cannulated Screw System is a stainless-steel bone fixation device; features cannulated, headless design for countersinking below bone surface. Used by surgeons for small bone fracture fixation, non-unions, and arthrodesis. Device provides mechanical stabilization of bone fragments. System is provided sterile. Line extension adds 3.6mm diameter screws in 25-55mm lengths. No software or electronic components.

Clinical Evidence

Bench testing only. Performed driving torque, torque to failure, and engineering calculations for torsional strength, bending strength, and pullout resistance. Simulated use testing validated that the modified device meets user needs.

Technological Characteristics

Stainless-steel bone screws; cannulated, headless design. Dimensions: 3.6mm diameter, 25-55mm lengths. Sterilized. Mechanical fixation principle. No software or electronic components.

Indications for Use

Indicated for fixation of intra-articular and extra-articular fractures, non-unions of small bones/fragments, arthrodesis of small joints, bunionectomies, and osteotomies in patients requiring bone fixation in areas including scaphoid, carpal bones, metacarpals, tarsals, metatarsals, patella, ulnar styloid, capitellum, and radial head/styloid.

Regulatory Classification

Identification

A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.

The INnate system screws are cannulated and feature a headless design that allows for the screw to be countersunk below the surface of the bone. The system is provided sterile. The subject of this submission is the addition of a Ø3.6mm version of the INnate screw to the system to be offered in lengths of 25 to 55mm. # INDICATIONS FOR USE The ExsoMed INnate Cannulated Screw System is intended for fixation of intra-articular and extra-articular fractures and non-unions of small bones and small bone fragments; arthrodesis of small joints; bunionectomies and osteotomies, including scaphoid and other carpal bones, metacarpals, tarsals, metatarsals, patella, ulnar styloid, capitellum, radial head and radial styloid. ## TECHNOLOGICAL CHARACTERISTICS The proposed modified device is substantially equivalent to the predicate, the ExsoMed ITN Cannulated Screw System. The design, materials, and intended use of the modified device are the same as the predicate devices. The mechanism of action of the 3.6mm INnate Cannulated Screw System is identical to the predicate devices in the same standard mechanical design, materials, shapes and sizes are utilized. There are no changes to the claims, intended use, clinical applications, performance specification or method of operation. Both the subject and predicate Cannulated Screw Systems are cleaned, packaged and sterilized using the same materials and processes. The ExsoMed 3.6mm INnate cannulated screw system differs from the predicate only in diameter, length and pitch. ## PERFORMANCE TESTING Verification analyses consisting of functionality testing were performed to demonstrate the equivalence of the new and predicate devices. Specifically, following tests were performed: - Driving Torque testing . - Torque to failure testing ● ExsoMed Corporation Special 510(k) – INnate Cannulated Screw System {5}------------------------------------------------ - . Engineering Calculations for torsional strength, bending strength and pullout resistance In addition, simulated use testing was performed to validate the modified device meets user needs. The results from these evaluations demonstrated that the subject INnate 3.6mm Cannulated Screws perform as intended. ## CONCLUSION The information summarized in the Design Control Activities Summary demonstrates that the modified INnate Cannulated Screws met the predetermined acceptance criteria for verification activities identified. There is no change to the fundamental scientific technology, indicated use or material type for the proposed line extension devices. ExsoMed concludes that the line extension devices (3.6mm INnate Cannulated Screws) introduce no new issues of safety or effectiveness compared with the predicate device.
