Intended Use

The Smith & Nephew Interference Screws are used for fixation of ligaments and tendons in patients requiring ligament and tendon repair.

Device Story

Titanium alloy bone fixation screws; used for ligament and tendon repair. Available in various diameters, lengths, and geometric configurations; cannulated and non-cannulated styles. Intended for surgical use by physicians. Device provides mechanical fixation of soft tissue to bone. Performance verified via insertion torque and pullout force testing.

Clinical Evidence

Bench testing only. Comparison of insertion torque and pullout force between subject device and predicate devices showed no statistically significant differences.

Technological Characteristics

Titanium alloy material; smooth or threaded metallic bone fixation fastener; available in cannulated and non-cannulated configurations; various diameters and lengths; supplied sterile or non-sterile (user-sterilizable).

Indications for Use

Indicated for fixation of ligaments and tendons in patients requiring ligament or tendon repair.

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.

Predicate Devices

• Acufex Interference Screws (K895711)
• Acufex Interference Screws (K900132)
• Oregon (Dyonics) Fixation System (K932027)
• Cannuflex Interference Screws (K921481)

### Description of Device E.

The Smith & Nephew Titanium Interference Screws are available in various geometric configurations. The Smith & Nephew Titanium Interference Screws arc made with titanium alloy material. The range in diameters and lengths, combined with the variations in geometric configurations, provide the surgeon with a wide variety of sizes/configurations to choose from. Screws are available in both cannulated and non-cannulated styles. The screws may be purchased either sterile or non-sterile, to be sterilized by the end user.

### Intended Use F.

The Smith & Nephew Interference Screws are used for fixation of ligaments and tendons in patients requiring ligament and tendon repair.

### G. Comparison of Technological Characteristics

Although there are some dimensional variations between the Smith & Nephew Titanium Interference Screw and the predicate devices, there are no new issues raised concerning safety or efficacy of the device.

### H. Summary Performance Data

Comparison of the results of the insertion torque testing and pullout force demonstrated that there were no statistically significant differences between the Smith & Nephew Titanium Interference Screw and the predicate devices.

Dear Ms. Lima:

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. In addition, FDA may publish further announcements concerning your device in the Federal Register.
