The XtraFix External Fixation System is indicated for use in construction of an external fixation frame for treatment of long bone (foot, femur, and tibia) and pelvic fractures that require external fixation. Specifically, the system is intended for:

Temporary stabilization of open or closed acute fractures with soft tissue injuries; .
. Definitive stabilization of open or closed fractures where open or alternative closed treatment is undesirable or otherwise contraindicated;
Stabilization of fractures in the context of polytrauma; .
Temporary or definitive stabilization of certain pelvic fractures or pelvic ring injuries; .
Arthrodesis and osteotomies with associated soft tissue problems; .
Stabilization of limbs after removal of total joint (knee, and ankle) arthroplasty for . infection or other failure;
Neutralization of fractures stabilized with limited internal fixation; .
. Stabilization of non-unions; and
. Intraoperative temporary stabilization tool to assist with indirect reduction.

Device Description

The XtraFix External Fixation System includes various elements designed to build a fixator construct. The system includes clamps, posts, bars, and fixation pins.

AI/ML Overview

The provided document describes the XtraFix External Fixation System, a medical device for stabilizing bone fractures. It does not contain information about a study with acceptance criteria and device performance in the context of an AI/algorithm-driven device. The document is a 510(k) summary, which is typically a premarket notification for a medical device demonstrating substantial equivalence to a legally marketed predicate device.

Specifically, the document states:

"The principles of operation of the XtraFix External Fixation System are the same as for the predicates."
"The XtraFix External Fixation System was characterized and evaluated according to the requirements outlined in FDA Guidance document, "Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment." Testing confirmed the device can be used in an MR environment under predetermined conditions. Therefore, the term "MR Conditional" can be used to describe the system in accordance with the guidance document."
"All evaluations determined that the XtraFix External Fixation System is substantially equivalent to the predicate devices."

This indicates that the "study" conducted was primarily focused on demonstrating MR compatibility and confirming the device's technological characteristics are similar to existing predicate devices, rather than a performance study with acceptance criteria for an AI-powered diagnostic or therapeutic tool.

Therefore, I cannot populate the requested table and information points as they pertain to AI/algorithm performance and ground truth, as that information is not present in the provided text. The device is a physical external fixation system, not a software-based AI device.

XtraFix External Fixation System K11155 510(k) Summary

Predicate Devices:

The XtraFix External Fixation System is similar to several predicates including the following:

ExtraOrtho XtraFix External Fixation System (K091258); .
Stryker Hoffmann II MRI External Fixation System (K053472); .
. Synthes Large External Fixation Clamps- MR S (K082650); and
Smith & Nephew Jet-X Unilateral Fixator (K072212). .

Technological Characteristics

The principles of operation of the XtraFix External Fixation System are the same as for the predicates. The XtraFix External Fixation System was characterized and evaluated according to the requirements outlined in FDA Guidance document, "Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment." Testing confirmed the device can be used in an MR environment under predetermined conditions. Therefore, the term "MR Conditional" can be used to describe the system in accordance with the guidance document.

Substantial Equivalence Information:

The XtraFix External Fixation System is similar to legally marketed devices listed previously in that they share similar indications for use and incorporate similar technological characteristics. All evaluations determined that the XtraFix External Fixation System is substantially equivalent to the predicate devices.

Dear Mr. Velez-Duran:

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.
