Device Description

The current SALVATION External Fixation System consists of rings, wires, wire fixation bolts, wire posts with bolts, half pin cubes with bolts, bushings, rocker plates with outsoles, insoles, etc. The Proximal Tibial Ring, Distal Tibial Ring and Foot Ring are designed with slots. This slot feature allows the fixation elements to slide to the desired position as opposed to the user having to handle small components (wire bolt and nut) to attach to the rings or taking the bolt out and placing it into a different hole. The system also includes tab rings with fixation holes to be used based on surgeon preference. As cleared in 510(k) K162033, the SALVATION External Fixation System is designed so that the SIDEKICK Circular and SIDEKICK EZ FRAME™ components are compatible and can be used with the SALVATION External Fixation system.

AI/ML Overview

This document is a 510(k) premarket notification for a medical device called the "SALVATION External Fixation System." It's from the FDA and pertains to mechanical devices designed for bone fixation, not an AI/ML powered device. As such, the information required to answer the questions about acceptance criteria for an AI/ML powered device, such as performance metrics, sample sizes for training and test sets, expert involvement, and ground truth establishment, is not present in this document.

Therefore, I cannot provide a table of acceptance criteria or details about a study proving the device meets those criteria based on the provided text. The document focuses on the substantial equivalence of the external fixation system to predicate devices based on mechanical and design characteristics, rather than performance metrics of an AI/ML algorithm.

Dear Rachel Roberts:

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 of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

(a)(6). Technological Characteristics Comparison

The subject devices included in the SALVATION™ External Fixation System Line Extension are technologically substantially equivalent to predicate devices in material, design features, size, and mechanical strength. The fundamental scientific technology of the modified device has not change relative to the predicate devices.

(b)(1). Substantial Equivalence - Non-Clinical Evidence

Mechanical Pull-out testing, Finite Element Analysis, and Engineering analysis demonstrated substantial equivalence comparing each modified component to the predicate components. The indications for use of the subject SALVATION™ External Fixation System are identical to the predicate SALVATION™ External Fixation System K162033.

(b)(2). Substantial Equivalence – Clinical Evidence

N/A

(b)(3). Substantial Equivalence - Conclusions

The design characteristics of the subject system do not raise any new types of questions of safety or effectiveness. From the evidence submitted in this 510(k), the subject devices can be expected to perform at least as well as the predicate devices.

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.
