The DVR® Crosslock Wrist Spanning Plate is indicated for skeletally mature patients for fixation of fractures, osteotomies and non-unions of the distal radius.

Device Description

The DVR® Crosslock Wrist Spanning Plate is a single-use plate for the fixation of fractures, osteotomies and non-unions of the distal radius. The plate spans the patient's wrist and is placed from the radial shaft to the second or third metacture pattern and patient anatomy. The plate provides ligamentotaxis on a temporary basis while the distal radius heals. The DVR® Crosslock Wrist Spanning Plate consists of a single, sterile-packed plate and is manufactured from titanium alloy (Ti-6AL-4V). The plate features hole clusters consisting of locking screw holes, a central screw cluster, and K-wire holes for preliminary fixation. There is a dorsal bend at the distal end of the plate to accommodate patient anatomy.

AI/ML Overview

The provided document describes a medical device called the "DVR® Crosslock Wrist Spanning Plate" and its clearance through the FDA 510(k) pathway. This pathway does not typically involve clinical studies proving novel efficacy, but rather substantial equivalence to a predicate device. Therefore, the information requested regarding acceptance criteria and studies specifically proving the device's performance in a clinical context (e.g., effect size with AI assistance, expert consensus, training set details) will not be present.

Instead, the document details non-clinical testing to demonstrate substantial equivalence to a predicate device.

Here's the information extracted from the document, focusing on the available details:

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

Acceptance Criteria (Set by Predicate Device)	Reported Device Performance
Static Testing:
Bending structural stiffness	Passed
Bending strength	Passed
Fatigue Testing:
Fatigue runout	Met acceptance criteria

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

Test Set Sample Size: Not applicable. The testing described is non-clinical, involving mechanical testing of the device itself, not human subjects or patient data.
Data Provenance: Not applicable. The testing was laboratory-based mechanical testing.

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 ground truth for mechanical testing is established by engineering standards and measurements, not expert human interpretation.

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

Not applicable. This concept applies to human interpretation or clinical trials, not mechanical performance testing.

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 for this device, as it is a bone fixation plate, not an AI-powered diagnostic or assistive technology.

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)

The "ground truth" for this device's performance evaluation was based on accepted engineering standards and the performance of a predicate device as defined by ASTM F382-17 (Standard Specification and Test Method for Metallic Bone Plates).

8. The sample size for the training set

Not applicable. This device does not involve machine learning or a "training set."

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

Not applicable. This device does not involve machine learning or a "training set."

Device Description Summary

Intended Use/Indications for Use

The DVR® Crosslock Wrist Spanning Plate is indicated for skeletally mature patients for fixation of fractures and non-unions of the distal radius.

21 CFR 807.92(a)(5)

21 CFR 807.92(a)(4)

{4}------------------------------------------------

Indications for Use Comparison

21 CFR 807.92(a)(5)

The subject device is only indicated for use in the the predicate device includes additional anatomical locations. The subject indications also identify the target population, as recommended for medical device labeling. The subject indications and inclusion of patient population do not affect safety and effectiveness of the device when used as labeled.

Technological Comparison

21 CFR 807.92(a)(6)

The subject system has the same or similar fundamental technology (indication regulation, principles of operation, geometric shape, materials, sterility, surgical, and MR compatibility) as the primary predicate. The subject system has the same or similar fundamental technology (shelf-life, packaging, biological safety, and sterilization parameters) as the reference predicates. Nonclinical tests were submitted and relied on in the premarket notification for a determination of substantial equivalence. ASTM F382-17 (Standard Specification and Test Method for Metallic Bone Plates) testing has passed acceptance criteria established by the predicate device, where applicable. The supporting evidence in this subject device is substantially equivalent to the predicate devices.

Non-Clinical and/or Clinical Tests Summary & Conclusions 21 CFR 807.92(b)

ASTM F382-17 Standard Specification and Test Method for Metallic Bone Plates testing was conducted in the determination of substantial equivalence. A 4-point bend test was performed via static and fatigue testing (bending strength, and fatigue runout) to determine substantial equivalence of the primary predicate. In addition, MR Safety analysis and testing was conducted per ASTM F2213, F2052, and F2182 to support MR Conditional labeling.

Clinical Data - Not Applicable

Static testing of the subject device (bending structural stiffiess and bending strength) passed the primary predicate acceptance criteria. Fatigue testing of the subject device (fatigue runout) met the primary predicate acceptance criterial that the subject device is as safe, as effective, and performs as well as the primary predicate. In addition, MR Safety analysis and testing supports MR Conditional labeling.

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.
