The T2 Femoral nail is a cylindrical, cannulated titanium alloy tube, slightly bowed to accommodate the shape of the femur. The T2 Femoral Nail may be inserted into the femoral canal using either a retrograde or antegrade surgical approach. The T2 Femoral Nail is available in diameters ranging from 9 to 15 mm and lengths ranging from 180 to 480 mm.

AI/ML Overview

The provided document is a 510(k) summary for a medical device (T2 Femoral Nail System) and does not contain information about a study that assesses the device's performance against pre-defined acceptance criteria.

This submission is a "line extension" for an existing device, adding new shorter nail lengths. The core of the submission relies on demonstrating "substantial equivalence" to a predicate device, meaning the new versions are considered to have the same intended use, technological characteristics, and safety/effectiveness as the previously cleared device.

Therefore, I cannot extract the requested information (acceptance criteria, device performance, sample sizes, ground truth details, MRMC study, or standalone algorithm performance) from the provided text. The document focuses on regulatory compliance based on equivalence rather than a new performance study for the device itself.

Predicate Device Identification

Description of Device Modification

The line extension involves the addition of two shorter nail lengths, 140 and 160 mm, throughout the entire diameter range. These shorter femoral nails do not have an anterior bow.

Intended Use

The T2 Femoral Nail System is a fracture fixation device comprised of femoral nails and the related locking screws, compression screws, and end caps. The T2 Femoral Nail System is intended to provide strong and stable internal fracture fixation with minimal soft tissue irritation. This device is utilized as an aid to healing, not as a substitute for normal intact bone and tissue.

Statement of Technological Comparison:

The design and function of the shorter T2 Femoral Nail are substantially equivalent to that of the predicate device.

Dear Ms. Ariemma:

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.

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); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
