## Intended Use

The EBI X FIX® DynaFix® System Hydroxyapatite (HA) Coated Screws are intended for use in association with the external fixation of bone.

## Device Story

EBI X FIX® DynaFix® System consists of bone screws with tapered threads available in cortical and cancellous patterns. Screws feature optional proprietary hydroxyapatite (HA) surface coating to enhance pin-bone interface fixation and reduce pin loosening. Device used by surgeons in clinical settings for external bone fixation. HA coating promotes osseointegration via direct bone-to-screw contact. Screws are provided sterile or non-sterile.

## Clinical Evidence

Bench testing only. Testing included biocompatibility, fatigue, and effectiveness evaluations to confirm safety and performance. Histologic examination demonstrated osseointegration with direct contact between bone and screw thread.

## Technological Characteristics

Materials: Stainless steel 316L per ASTM F138. HA coating applied per ASTM F1185 and Device Master File MAF-339. Tapered thread design; cortical and cancellous patterns. Sterilization: Sterile or non-sterile.

## Regulatory 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.

- EBI X FIX® DynaFix® System HA Coated Bone Screws 2. Proprietary Name: Common Name: External Fixation Bone Screws Classification Name/Code: Pin, Fixation, Threaded (888.3040)/JDW
- 3. Predicate or legally marketed devices that are substantially equivalent:
	- 트 Orthofix® External Fixation Screw with Hydroxapatite Coating-Orthofix Srl
- Description of the device: The bone screws have a tapered thread diameter and are available in a variety of 4. diameters and lengths in both cortical and cancellous thread patterns. The screws will be available with and without the additional proprietary hydroxapatite surface coating on the threads, and will be sold sterile and nonsterile. The coating has been shown to enhance fixation at the pin-bone interface and to reduce the incidence of pin loosening. Furthermore, osseointegration with direct contact between the bone and the screw thread was seen on histologic examination.

Intended Use: The EBI X FIX® DynaFix® System Hydroxyapatite (HA) Coated Screws are intended for use in association with the external fixation of bone.

- 5. Materials: The HA Coated bone screws are manufactured from stainless steel, 316L per ASTM F138. The HA coating is applied by a proprietary process according to Device Master File MAF-339 and ASTM F 1185.
- 6. Comparison of the technological characteristics of the device to predicate devices: There are no significant differences between the HA coated bone screws and other currently marketed bone screws since the addition of a HA coating does not adversely affect the use of the bone screws. The coated screws underwent biocompatibility, fatigue, and effectiveness testing to determine if the device was safe and effective. It is substantially equivalent* to the predicate devices in design and function.

<sup>*</sup> Any statement made in conjunction resarcing a determination of substantial equivalence to any other product is intended only to relate to whether the product can be lawfully me-market approval or reclassification and is not intended to be interpreted as an admission or any other type of evidence in patent litigation (Establishment Registration and Premarket Notification Procedures, Final Regulation, Preamble, August 23, 1977, FR 42520 (Docket No. 76N-0355.)]

Dear Mr. Caparotta:

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.

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 Regulations, 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 Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
