Intended Use

The CSS Cannulated Screw System will be indicated for use in long and small bone fracture fixation, which includes the following; - Fractures of the tarsals and metatarsals - Fractures of the olecranon, distal humerous - Fractures of the radius and ulna - Patella fractures - Distal tibia and pilon fractures - Fractures of the fibula, medial malleolus, os calcis - Tarso-metatarsal and metatarsal phalangeal arthrodesis - Metatarsal and phalangeal osteotomies - Osteochondritis dissecans - Ligament fixation - Other small fragment, cancellous bone fractures and osteotomies

Device Story

CSS Cannulated Screw System consists of self-tapping cannulated screws, washers, and guide wires; used for bone fixation in orthopedic surgical procedures. Device provides mechanical stabilization of fractures and osteotomies. Surgeons select appropriate screw diameter, length, and thread configuration based on anatomical requirements. Washers (flat, contoured, partial contoured, domed) provide anatomical fit. System is used in clinical/surgical settings. Output is physical fixation of bone fragments, aiding healing and structural stability.

Clinical Evidence

No clinical data. Evidence consists of bench testing and Finite Element Analysis (FEA) comparing the subject device to the predicate.

Technological Characteristics

Materials: Titanium Ti-6Al-4V ELI Alloy (ASTM F-136). Components: Cannulated screws, washers, guide wires. Principle: Mechanical bone fixation via threaded fasteners. Design: Self-tapping, various diameters/lengths/thread configurations. Sterilization: Not specified.

Indications for Use

Indicated for long and small bone fracture fixation, including tarsal, metatarsal, olecranon, distal humerus, radius, ulna, patella, distal tibia, pilon, fibula, medial malleolus, and os calcis fractures; also indicated for arthrodesis, osteotomies, osteochondritis dissecans, and ligament fixation.

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.

## Device Description

The CSS Cannulated Screw System consists of cannulated screws of various diameters, lengths and thread configurations. The system also includes correspondingly sized washers, the use of which are optional, as well as guide wire and various instruments.

The cannulated screws are self tapping. They are made from made from Titanium Ti-6Al-4V ELI Alloy in conformance with ASTM F-136 Standard Specification for Wrought Titanium 6Al-4V ELI Alloy for Surgical Implant Applications.

The CSS System includes (4) different types of washers. These are; Flat Washers, Contoured Washers, Partial Contoured Washers, and Domed Washers. The various styles are intended to offer the surgeon a variety of anatomical fit to the bone in certain applications.

## Performance Data

A Finite Element Analysis (FEA) was performed on the CSS Cannulated Screw System, in comparison to its' predicate, the Asnis III. Performance testing was also conducted to confirm the results of the FEA. Results clearly demonstrate that the CSS System is substantially to its' predicate.

Dear Mr. Strnad:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.
