T2 Proximal Humeral Nail: The T2 Proximal Humeral Nail is intended to be used for various types of proximal and/or diaphyseal fractures of the humerus. The nails are inserted using an opened or closed technique and can be static, dynamic and compression locked. The T2 Proximal Humeral Nail is intended for single use only. Examples of specific indications according to AO classification include Type A-Fractures, dislocated, Type BFractures, dislocated, Type C-Fractures, with intact calotte, or Humeral Fractures according to Neer-Classification.
T2 Humeral Nail: The T2 Humeral Nail is intended to provide temporary stabilization of various types of fractures, malunions and nonunions of the humerus. The nails are inserted using an opened or closed technique and can be static, dynamic and compression locked. The subject and predicate devices are indicated for use in the humerus. Types of fractures include, but not limited to fractures of the humeral shaft, non-unions, malalignments, pathological humeral fractures, and impending pathological fractures.
This 510(k) submission is a line extension to the T2 Nailing System to add a new Proximal Humeral Nail with accessories, additional sizes of the T2 Humeral Nail, additional End Caps for various T2 nails and additional lengths of T2 Locking Screws. The T2 Nailing System also has the same basic design concepts as the predicate devices.
The provided text is a 510(k) Premarket Notification for the T2 Humeral Nail System Line Extension, which is a medical device for bone fixation. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than proving clinical efficacy or diagnostic accuracy through human studies with specific acceptance criteria and ground truth.
Therefore, the requested information regarding acceptance criteria, study details, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, and ground truth establishment cannot be extracted from the provided text.
Here's why and what can be extracted:
- Acceptance Criteria & Reported Performance (Table): Not applicable for this type of submission. This device is a mechanical implant, not a diagnostic or AI-driven device with performance metrics like sensitivity, specificity, etc. The "performance" is mechanical equivalence.
- Sample Size (Test/Training) & Data Provenance: Not applicable. There's no "test set" or "training set" in the context of typical AI/diagnostic device studies. The "study" mentioned is an FEA (Finite Element Analysis).
- Number of Experts & Qualifications / Adjudication Method / Ground Truth Type: Not applicable. These relate to studies involving human interpretation or clinical outcomes, which are not detailed here. The "ground truth" for a mechanical device is typically its physical properties and intended mechanical behavior.
- MRMC Comparative Effectiveness Study: Not applicable. There's no AI component or human reader interaction tested against the device itself.
- Standalone Performance: Not applicable in the context of AI algorithms. The device performs its function as a mechanical implant.
What the document does provide regarding "performance" and "study":
The document states:
- "The T2 Nailing System also has the same basic design concepts as the predicate devices."
- "FEA Analysis demonstrated comparable mechanical properties to the predicate device."
This indicates that the "study" was a Finite Element Analysis (FEA), and the "acceptance criterion" was demonstrating comparable mechanical properties to the predicate device. This is how mechanical equivalence is established for such devices. However, specific numerical acceptance criteria (e.g., "flexural strength must be within 5% of predicate") and the precise results are not detailed in this summary.
In summary, the provided document is a regulatory submission for a mechanical medical device, not a diagnostic or AI device. Hence, most of the requested information pertinent to AI/diagnostic study design is not present.

This 510(k) submission is a line extension to the T2 Nailing System to add a new Proximal Humeral Nail with accessories, additional sizes of the T2 Humeral Nail, additional End Caps for various T2 nails and additional lengths of T2 Locking Screws.
The T2 Proximal Humeral Nail is intended for the fixation of various types of proximal and/or diaphyseal fractures of the humerus. The T2 Humeral Nail is intended to provide temporary stabilization of various types of fractures, malunions and nonunions of the humerus.
The intended use of the subject devices is identical to the following predicate devices: Polarus Proximal Humeral Nail (Acumed, Inc.) and Zimmer's M/DN Humeral Nail for the T2 Proximal Humeral Nail and the Polarus Plus Humeral Nail (Acumed, Inc.), Zimmer's M/DN Humeral Nail, Zimmer Inc. and the previously cleared T2 Humeral Nail System by Howmedica Osteonics Corp. for the T2 Humeral Nail.
The T2 Nailing System also has the same basic design concepts as the predicate devices. FEA Analysis demonstrated comparable mechanical properties to the predicate device.

Dear Ms. Kelly:
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.
