The Arthrex Distal Radius Plate System is intended for internal fixation for fractures and reconstruction of the small bones, primarily including the distal radius and distal ulna. Examples of these internal fixations and reconstructions include compression fractures, intra-articular and extra-articular fractures, displaced fractures, osteotomies, nonunions and malunions.

This system can be used for palmar, dorsal or orthogonal application.

The Arthrex Low Profile Screws (2.0-2.4mm solid) are intended to be used as stand-alone bone screws, or in a plate-screw system for internal bone fixation for bone fractures, fusions, osteotomies and non-unions in the ankle, foot, hand, and wrist. When used with a plate, the screw may be used with the Arthrex Low Profile, Small Fragment Plates, Distal Extremity Plates, and Distal Radius Plates.

The Arthrex Low Profile Screws (2.0-3.0mm cannulated) are intended to be used as standalone bone screws for internal bone fixation for bone fractures, fusions, osteotomies and nonunions in the ankle, foot, hand, and wrist.

The Arthrex Low Profile Screws (2.7mm and larger, solid) are intended to be used as standalone bone screws, or in a plate-screw system for internal bone fixation for bone fractures, fusions, osteotomies and non-unions in the ankle, foot, hand, wrist, clavicle, scapula, olecranon, humerus, radius, ulna, tibia, calcaneous, femur and fibula. When used with a plate, the screws may be used with the Arthrex Low Profile, Small Fragment Plates, Fracture Plates, Distal Extremity Plates, Distal Radius Plates, Humeral Fracture Plates, and Osteotomy Plates.

The Arthrex Low Profile Screws (3.5mm and larger, cannulated) are intended to be used as stand-alone bone screws for internal bone fixation for bone fractures, fusions, osteotomies and non-unions in the ankle, foot, hand, wrist, clavicle, scapula, olecranon, humerus, radius, ulna, tibia, calcaneous, femur and fibula.

Device Description

The Arthrex Distal Radius Plate System is a family of plates offered in various widths, thicknesses and lengths and locking screws in various diameters and lengths.

AI/ML Overview

Here's a breakdown of the requested information based on the provided text:

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

Acceptance Criteria	Reported Device Performance
Bending strength comparable to predicate device	Demonstrated to be comparable
Fatigue strength comparable to predicate device	Demonstrated to be comparable

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

The document does not specify a "test set" in the context of clinical data or algorithm performance. The evaluation was based on mechanical testing data.

Sample size for mechanical testing: Not explicitly stated.
Data provenance: Not specified (e.g., in-house lab, third-party lab, etc.).

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. The study was mechanical testing, not a clinical study requiring expert ground truth for interpretation.

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

Not applicable. The study was mechanical testing, not a clinical study requiring adjudication.

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

No MRMC comparative effectiveness study was done. This is a medical device (plate and screw system) and not an AI-assisted diagnostic tool.

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

This question is not applicable as the device is a physical medical implant, not an algorithm.

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

For the mechanical testing, the "ground truth" implicitly refers to the mechanical properties (bending strength and fatigue strength) of the predicate devices. The new device's performance was compared against these established properties.

8. The sample size for the training set

Not applicable. This is a medical device, not an AI model that requires a training set.

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

Not applicable. This is a medical device, not an AI model.

Summary of the Study:

The submission for the Arthrex Distal Radius Plate System is a traditional 510(k) premarket notification. The primary evidence presented for substantial equivalence to predicate devices is based on mechanical testing.

The study demonstrated that:

The materials used (titanium) are substantially equivalent to those in predicate devices.
The bending strength of the proposed devices is comparable to that of the predicate device.
The fatigue strength of the proposed devices is comparable to that of the predicate device.

These mechanical performance comparisons are the basis for the FDA's determination of substantial equivalence, indicating that the device meets its acceptance criteria by performing similarly to already legally marketed devices.

Dear Ms. Smith:

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

Regulation Number and Section

§ 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.
