## Device Story

Dunamis Interference Screw is a metallic bone fixation fastener used for reattaching soft tissue or bone to bone. Device is utilized by surgeons in orthopedic procedures including cruciate ligament reconstruction, shoulder stabilization, and various foot/ankle/hand repairs. Screw provides mechanical fixation to secure tissue during healing. Performance is verified through bench testing of torsional yield strength, insertion/removal torque, and axial push-out strength. Device is provided sterile for single-use application.

## Clinical Evidence

No clinical data. Substantial equivalence is supported by bench testing, including torsional yield strength, maximum torque, breaking angle, insertion and removal torque, axial push-out strength, self-tapping force, biocompatibility, sterilization validation, ethylene oxide residuals, sterile barrier packaging performance, and aging studies.

## Technological Characteristics

Metallic bone fixation fastener (interference screw). Characteristics include torsional yield strength, insertion/removal torque, and axial push-out strength. Sterilized via ethylene oxide. No software or electronic components.

## 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.

## Predicate Devices

Dear Mr. Dean,

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical devicerelated adverse events) (21 CFR 803); good manufacturing practice requirements as set
