Device Story

Osteo 4.0mm Cannulated Screw System consists of self-tapping cannulated screws and washers; used for bone fixation in orthopedic procedures. Device provides mechanical stabilization of bone fragments or ligaments. Operated by surgeons in clinical/OR settings. Output is physical fixation of bone/tissue. Benefits include stabilization of fractures and support for healing. System is purely mechanical; no electronic or software components.

Clinical Evidence

No clinical data. Bench testing only.

Technological Characteristics

Material: Titanium 6Al-4V ELI alloy. Design: Self-tapping cannulated screw (4.0mm thread diameter) and washer (7.0mm outer diameter, 4.0mm inner diameter). Mechanical fixation principle. Provided sterile and non-sterile.

Indications for Use

Indicated for patients requiring fixation of long and small bone fractures, osteochondritis dissecans, and ligament fixation. Specific applications include fractures of the olecranon, distal humerus, ulna, radius, patella, distal tibia, pilon, tarsals, metatarsals, and pelvic ring; also indicated for arthrodeses and osteotomies. Contraindicated for pedicular screw fixation/attachment to the cervical, thoracic, or lumbar vertebral column.

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.

Dear Ms. Staub:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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. Note that labeling or otherwise promoting a device for pedicular screw fixation/attachment would cause the device to be adulterated under 501(f)(1) of This device, if intended for use in pedicular screw the Act. fixation/attachment, would be found not substantially equivalent and would be a class III device under Section ---513 (f) of the Act. Class III devices are required to have an approved premarket approval (PMA) application prior to marketing. Accordingly:

- The package insert must prominently state that the device 1. is intended for the specific use(s) described in the enclosure only; and
- 2. You may not label or in any way promote this device for pedicular screw attachment to, or fixation of the cervical, thoracic or lumbar vertebral column. If this

device is a screw with outer diameters of 3 mm - 10 mm and overall lengths of 10 mm - 75 mm inclusively, the package insert must include the following statement, This device is not approved for screw "WARNING: attachment or fixation to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine." Any pedicular screw fixation/attachment to the cervical, thoracic or lumbar vertebral column of this device is considered investigational and may only be investigated as a significant risk device in accordance with the investigational device exemption (IDE) regulations under 21 CFR, Part 812. All users of the device for pedicular screw fixation/attachment must receive approval from their respective institutional review boards (IRBs) and the Food and Drug Administration (FDA) prior to conduct of the investigation.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major. regulations affecting your device can be found in the Code of Federal Requlations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical General requlation (21 CFR Part 820) and that, Devices: through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP requlation may result in regulatory In addition, FDA may publish further announcements action. concerning your device in the Federal Register.
