Device Description

The Bonebridge Osteosynthesis Plating System is intended for treating fractures of various bones. It consists of plates, locking and non-locking screws for fixation and corresponding instruments. The plating system is further subdivided into variants/types based on the anatomical location of the fracture.

Plates and screws are made of stainless steel (ISO 5832-1 or ASTM F138 or ASTM F139) or pure titanium (ASTM F67 or ISO 5832-2). All materials used are biocompatible, corrosion-resistant and nontoxic in a biological environment. Surgical instruments are made of stainless steel (ISO 5832-1 or ASTM F138 or ASTM F899), medical grade PEEK, medical grade EPDM terpolymer, or medical grade silicone.

All plates are sterilized with gamma irradiation and delivered sterile. Screws and instruments are delivered non-sterile. Devices supplied in a non-sterile condition must be cleaned and steam sterilized prior to surqical use. Non-clinical testing has demonstrated the devices are MR Conditional.

AI/ML Overview

The provided text describes a 510(k) premarket notification for the Bonebridge Osteosynthesis Plating System. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving independent effectiveness through a clinical study with detailed acceptance criteria for diagnostic performance. Therefore, the information typically requested regarding acceptance criteria for diagnostic accuracy, sample sizes for test/training sets, expert ground truth establishment, or multi-reader multi-case studies is not directly applicable or available in this document.

However, the document does list various performance tests conducted to establish substantial equivalence. I will present the information related to device performance and the testing conducted, framed within the principles of acceptance criteria where possible.

Here's a breakdown of the requested information based on the provided text, acknowledging the limitations inherent in a 510(k) summary:

1. Table of acceptance criteria and reported device performance:

The document doesn't explicitly state "acceptance criteria" with numerical thresholds for performance like sensitivity or specificity, as it's not a diagnostic device. Instead, it describes various engineering and material tests. The acceptance criterion for these tests is generally that the device performs equivalently to or better than the predicate device, or meets relevant international standards.

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

This information is not provided in the given text. The document refers to "testing" performed (e.g., static and dynamic testing for plates, testing for screws, packaging validation, MRI safety tests), but it does not specify the sample sizes of devices or materials used for these engineering tests. There's no "test set" in the context of diagnostic data.

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)

This information is not applicable/provided as this is an orthopedic implant (osteosynthesis plating system), not an AI/diagnostic device that would require expert-established ground truth for a test set. Usability studies were conducted with "study participants," but their qualifications or number for establishing ground truth are not detailed.

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

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

This information is not applicable/provided in the context of diagnostic accuracy. For the engineering tests, the "ground truth" would be established by the specifications of the materials, the design requirements, and the standards (e.g., ISO, ASTM) against which the device was tested. For usability, the ground truth is the successful and safe operation by participants.

8. The sample size for the training set

This information is not applicable/provided. This device is an orthopedic implant and does not involve AI or a "training set" in the machine learning sense.

§ 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.
