• Attributes: Therapeutic

Intended Use

The Howmedica Osteonics Radial Head Prosthesis is indicated for replacement of the proximal end of the radius in cases of rheumatoid arthritis; degenerative or post-traumatic disabilities presenting pain, crepitation and decreased motion at the radio-humeral and/or proximal radioulnar joint involving joint destruction and/or subluxation visible on x-ray; resistance to conservative treatment; fracture of the radial head; and symptomatic sequela after radial head resection. It is also indicated for use in revision procedures following failed radial head arthroplasty. This device is intended for cemented use only.

Device Story

The Howmedica Osteonics Radial Head Prosthesis is a metallic implant designed to replace the proximal end of the radius. It features a highly polished ulnar bearing surface and a distal stem. The device is available in various sizes (8mm-11mm small; 9mm-15mm medium). It is intended for surgical implantation by an orthopedic surgeon in a clinical setting to restore joint function in patients with radio-humeral or proximal radioulnar joint pathology. The prosthesis is secured using bone cement. By replacing the damaged radial head, the device aims to alleviate pain, improve joint motion, and address structural joint destruction or subluxation.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Material: Vitallium Alloy compliant with ASTM F1537. Design: Highly polished ulnar bearing surface with distal stem. Sizes: 8-11mm (small) and 9-15mm (medium). Fixation: Cemented.

Indications for Use

Indicated for patients requiring replacement of the proximal radius due to rheumatoid arthritis, degenerative or post-traumatic disabilities (with pain, crepitation, decreased motion, joint destruction, or subluxation), radial head fractures, or symptomatic sequela post-radial head resection. Also indicated for revision of failed radial head arthroplasty. Intended for cemented use.

Regulatory Classification

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.

### 510(k) Summary

Device: Howmedica Osteonics Radial Head Prosthesis

The Howmedica Osteonics Radial Head Prosthesis is a highly polished unar bearing surface with a distal stem. The radial head prosthesis is available in a variety of sizes ranging from 8mm to 11mm small and 9mm to 15mm medium components.

The Howmedica Ostconics Radial Ilcad I'rosthesis is indicated for replacement of the proximal end of the radius in cases of rheumatoid arthritis; dogenerative or post-traumatic disabilities. presenting pain, crepitation and decreased motion at the radio-humeral and/or proximal radioulnar joint involving joint destruction and/or subluxation visible on x-ray; resistante to conservative treatment; fracture of the radial head; and symptomatic sequela after radial head resection. It is also indicated for use in revision procedures following failed ratial head arthroplasty. This device is intended for comented use only.

The radial head prosthesis will be fabricated from Vitallium® Alloy which complies to ASTM standard Ii 1537.

The substantial equivalence of the Howmedica Ostconics Radial Flead Prosthesis is based upon equivalence in intended use, materials, design, and operational principles to the Wrighto Modical Technology, Inc. Metallic Radial Head Implants (K944507), the Avanta Orthopacidia, Inc Radial Ilead Implant (K982288) and the Smith & Nophew, Inc. Radial Head Prosuless s (K992220).

Dear Ms. Daudelin:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). You may, therefore, market the device, subject to the general control provisions of the Act. The general control provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
