## Indications for Use

The Arthrex Radial Head Replacement System is indicated for: · Replacement of the radial head for degenerative or post-traumatic disabilities presenting pain, crepitation, and decreased motion at the radio-humeral and/or proximal radio-ulnar joint with: a) joint destruction and/or subluxation visible on x-ray; and/or b) resistance to conservative treatment. · Primary replacement after fracture of the radial head. · Symptomatic sequelae after radial head resection. · Revision following failed radial head arthroplasty. The Cobalt Chrome stems are intended to be free floating and the Titanium Alloy stems are intended to be press-fit.

## Device Story

Arthrex Radial Head Replacement System is a modular, fixed-axis radial head prosthesis; used for radial head replacement in adults. System consists of polished, concave CoCrMo radial head; interchangeable with two stem options: grit-blasted Ti-6Al-4V ELI stem for press-fit fixation or smooth CoCrMo stem for free-floating application. Device addresses comminuted radial head fractures untreatable by internal fixation. Implanted by orthopedic surgeons in clinical/OR settings. Provides mechanical replacement of radial head to restore joint function, reduce pain, and improve motion. Provided sterile via Gamma radiation for single-use.

## Clinical Evidence

Bench testing only. No clinical data provided. Testing included Taper Disassociation (ASTM F2009-20), Fatigue Testing, Fretting Corrosion Analysis (ASTM F1875-98), and MRI Safety Testing (ASTM F2182, F2052, F2119, F2213) compared against predicate and reference devices.

## Technological Characteristics

Modular radial head prosthesis. Materials: CoCrMo (ASTM F1537/ISO 5832-12) for head and free-floating stem; Ti-6Al-4V ELI (ASTM F136-13/ISO 5832-3) for press-fit stem. Fixed-axis design. Sterilization: Gamma. No software or electronic components.

## Regulatory Identification

An elbow joint radial (hemi-elbow) polymer prosthesis is a device intended to be implanted made of medical grade silicone elastomer used to replace the proximal end of the radius.

Received: June 30, 2026

Dear Rebecca Homan:

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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

Your device is also subject to, among other requirements, the Quality Management System Regulation (QMSR) (21 CFR Part 820), which includes, but is not limited to, ISO 13485 clause 7.3 (Design controls), ISO 13485 clause 8.3 (Nonconforming product), ISO 13485 clause 8.5.2 (Corrective action), and ISO 13485 clause 8.5.3 (Preventative action). Please note that regardless of whether a change requires premarket review, the QMSR requires device manufacturers to review and approve changes to device design and production (ISO 13485 clause 7.3 and ISO 13485 clause 7.5) and document changes and approvals in the Medical Device File (ISO 13485 clause 4.2.3).

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 device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-products); good manufacturing practice requirements as set forth in the Quality Management System Regulation (QMSR) (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-devices/medical-device-safety/medical-device-reporting-mdr-how-report-medical-device-problems.

For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance) and CDRH Learn (https://www.fda.gov/training-and-continuing-education/cdrh-learn).

into the radial canal. A second option is a free floating stem manufactured from CoCrMo (conforming to ASTM F1537/ISO 5832-12) with a smooth surface to free float in the radial canal. The Arthrex Radial Head Replacement System will be used to address comminuted fractures of the radial head that cannot otherwise be treated with plates and screws for fusion of bone fragments. The devices within the Arthrex Radial Head Replacement System are provided sterile (Gamma) and are packaged in a dual-barrier configuration for single-use.

The Arthrex Radial Head Replacement System is indicated for:

- Replacement of the radial head for degenerative or post-traumatic disabilities presenting pain, crepitation, and decreased motion at the radio-humeral and/or proximal radio-ulnar joint with:
  a) joint destruction and/or subluxation visible on x-ray; and/or
  b) resistance to conservative treatment.
- Primary replacement after fracture of the radial head.
- Symptomatic sequelae after radial head resection.
- Revision following failed radial head arthroplasty.

The Cobalt Chrome stems are intended to be free floating and the Titanium Alloy stems are intended to be Press-Fit.
