Intended Use

Synthes (USA) LCP Proximal Femur Hook Plate is intended for fractures of the femur including: fractures of the trochanteric region, trochanteric simple, cervicotrochanteric, trochanterodiaphyseal, multifragmentary pertrochanteric, intertrochanteric, intertrochanteric reversed, or transverse or with additional fracture of medial cortex. Fractures of the proximal end of the femur combined with ispsilateral shaft fractures, metastatic fracture of the proximal femur and osteotomies of the proximal femur.

Device Description

The LCP Proximal Femur Hook Plates are contoured to match the anatomy of the proximal femur with a limited contact low profile design. The plate has dynamic compression holes combined with conical shaped threaded screw holes, which accept 4.5 mm cortex, 4.5 mm shaft screws, 4.0 mm or 5.0 mm locking screws, 5.0mm cannulated screws, and 7.3 mm cannulated locking & cannulated conical screws. The plates are available in a various lengths.

AI/ML Overview

The provided text is a 510(k) summary for the Synthes (USA) LCP Proximal Femur Hook Plates. This document details the regulatory pathway for a medical device by demonstrating its substantial equivalence to a legally marketed predicate device.

Crucially, a 510(k) submission for this type of device (metallic bone fixation appliances) typically relies on demonstrating substantial equivalence in design, materials, and intended use to an existing predicate device, rather than on new clinical performance studies with specific accuracy metrics and ground truth evaluations like those for diagnostic AI devices.

Therefore, most of the requested information regarding acceptance criteria, study design, sample sizes, expert ground truth, and comparative effectiveness studies is not applicable to this 510(k) submission.

Here's an analysis based on the available information:

1. A table of acceptance criteria and the reported device performance

  • Not applicable. This submission doesn't present performance metrics like those for diagnostic AI devices (e.g., sensitivity, specificity, AUC). The "acceptance criteria" for a 510(k) for this type of implantable device are based on demonstrating substantial equivalence to a predicate device in terms of design, materials, and intended use, often supported by mechanical testing rather than clinical performance-based metrics. The document states: "Comparative information presented supports substantial equivalence."

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

  • Not applicable. There is no "test set" in the context of clinical performance data described. Substantial equivalence is typically demonstrated through engineering analyses, bench testing, and comparison of design specifications to the predicate device.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

  • Not applicable. Ground truth establishment by experts for a test set is not part of this type of 510(k) submission.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

  • Not applicable. No adjudication method for a test set is described.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

  • Not applicable. This device is a bone fixation plate, not an AI diagnostic tool. MRMC studies are not relevant here.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

  • Not applicable. This device is a physical implant, not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

  • Not applicable. "Ground truth" in the diagnostic AI sense is not relevant for this device's 510(k) submission. The "ground truth" equivalent would be established engineering standards, material properties, and clinical performance data of the predicate device that the new device is compared against.

8. The sample size for the training set

  • Not applicable. There is no "training set" as this is not an AI/machine learning device.

9. How the ground truth for the training set was established

  • Not applicable. Not an AI/machine learning device.

Summary relevant to this 510(k):

The Synthes (USA) LCP Proximal Femur Hook Plates gained market clearance through a 510(k) submission by demonstrating substantial equivalence to the Synthes (USA) LCP Proximal Femur Plates (predicate device). This means the FDA concluded that the new device is as safe and effective as the predicate device already on the market, based on a comparison of intended use, technological characteristics (design, materials), and performance (often mechanical testing for implants) without necessarily requiring new clinical trials or performance studies against specific accuracy metrics. The key information is the comparison to the predicate device, not new performance data against a specific acceptance criterion table.

Dear Ms. Boyle:

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 10 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.

§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.

(a)
Identification. Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
