The MedShape DynaFuse Fixation System is indicated for use in bone reconstruction, osteotomy, arthrodesis, joint fusion, fracture repair, and fracture fixation of bones appropriate for the size of the device.

Device Description

The proposed MedShape DynaFuse Fixation System is a sterile, single use orthopedic implant system consisting of a threaded bone fastener and washer. The DynaFuse Fixation System is designed to apply compression across a target fracture or fusion site and is intended to be used for fracture and osteotomy fixation, including joint arthrodesis. The devices provided sterile, intended for single use, and are comprised of titanium alloy and nickel-titanium.

AI/ML Overview

I am sorry, but based on the provided text, there is no information about acceptance criteria, device performance metrics (like sensitivity, specificity, accuracy), or any clinical study details such as sample size, data provenance, expert ground truth, or adjudication methods in the context of an AI/algorithm-enabled medical device.

The provided document is a 510(k) premarket notification for the DynaFuse Fixation System, which is a physical orthopedic implant system (a threaded bone fastener and washer). The tests mentioned (Static Torsion Test, Static Strain Test, Fatigue Strain Test, Bacterial endotoxin testing) are engineering and biocompatibility tests for physical medical devices and are not related to the performance of an AI or software algorithm.

Therefore, I cannot fulfill your request to describe the acceptance criteria and study proving device meets them for an AI/algorithm-based device from this document.

Dear Ryan O'flaherty:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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

{1}------------------------------------------------

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 of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.

For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/medicaldevices/device-advice-comprehensive-regulatory-assistance) and CDRH Learn (https://www.fda.gov/training-and-continuing-education/cdrh-learn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic. See the DICE website (https://www.fda.gov/medical-device-advice-comprehensive-regulatoryassistance/contact-us-division-industry-and-consumer-education-dice) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).

H. Indications for Use:

l. Comparison of Characteristics / Performance Testing / Substantial Equivalence: The MedShape DynaFuse Fixation system and its predicate devices have similar indications for use, design, materials, and technological principles of operation.
The following non-clinical tests were performed to demonstrate substantial equivalence to the predicate devices:
Static Torsion Test per ASTM F543
Static Strain Test per ASTM F2516
Fatigue Strain Test per ASTM E606
Bacterial endotoxin testing based on an endotoxin limit of 20EU/device per ANSI/AAMI ST72:2011

Additional engineering analysis of the MedShape DynaFuse Fixation System and the predicate devices was also performed to demonstrate substantial equivalence.

No new questions of safety or effectiveness were identified during device testing and analysis; therefore, the DynaFuse Fixation System is considered substantially equivalent to the predicate devices.

Regulation Number and Section

§ 888.3040 Smooth or threaded metallic bone fixation fastener.

(a)
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.(b)
Classification. Class II.
