The Radial Head Prosthesis is intended for replacement of the proximal end of the radius due to degenerative or post-traumatic disabilities presenting pain, crepitation and decreased motion at the radiohumeral and/or proximal radio-ulnar joint involving joint destruction or subluxation visible on xray, resistance to conservative treatment; primary replacement after fracture of the radial head; and symptomatic sequelae after radial head resection.
The Radial Head Prosthesis, like the predicate devices, includes various sizes of implants to accommodate the requirements of patient anatomy.
This looks like a 510(k) summary for a medical device (Radial Head Prosthesis) submitted to the FDA. The provided text does not include information about acceptance criteria or a study proving the device meets those criteria.
Instead, the document focuses on:
- Device identification: Submitter, device name (K992220), classification, etc.
- Predicate devices: List of similar, legally marketed devices (Avanta Orthopaedics, Swanson Titanium, Implex).
- Device description: General information about the Radial Head Prosthesis.
- Intended use: Specific medical conditions for which the device is designed.
- Technological characteristics: Material (Cobalt-Chrome, ASTM F 90, ISO 5832-5).
- FDA correspondence: The letter from the FDA stating that the device is substantially equivalent to predicate devices.
- Indications for Use statement: A formal statement of the device's intended use.
Therefore, I cannot provide the requested information regarding acceptance criteria and studies, as this information is not present in the provided text.
To answer your questions, I would need a different document, typically a more detailed report or a specific section of the 510(k) submission that outlines performance testing and acceptance criteria. For devices like prostheses, this often involves:
- Mechanical Testing: Fatigue testing, static strength testing, wear testing.
- Biocompatibility Testing: Evaluating the material's interaction with the body.
- Clinical Data (if applicable): While not always required for 510(k) new devices based on predicate devices, sometimes clinical data is used to support substantial equivalence.
Without that specific information, I cannot fill out the requested table or answer the detailed questions about sample sizes, ground truth, expert qualifications, or MRMC studies.

Subject device description:
The Radial Head Prosthesis, like the predicate devices, includes various sizes of implants to accommodate the requirements of patient anatomy.
Subject device intended use:
The Radial Head Prosthesis is intended for replacement of the proximal end of the radius due to:
- degenerative or post-traumatic disabilities presenting pain, crepitation and decreased ● motion at the radiohumeral and/or proximal radio-ulnar joint with:
- joint destruction or subluxation visible on x-ray ●
- . resistance to conservative treatment
- . primary replacement after fracture of the radial head
- symptomatic sequelae after radial head resection ●
The Radial Head Prosthesis is for single use only.
Technolocgical Characteristics:
The Radial Head Prosthesis is similar to legally marketed devices listed above in that all of these devices are indicated for radial head replacement and are similar in technological characteristics. The Radial Head Prosthesis is manufactured from Cobalt-Chrome, ASTM F 90, ISO 5832-5.

Re: K992220 Trade Name: Radial Head Prosthesis Regulatory Class: II Product Code: KWI Dated: February 7, 2000 Received: February 10, 2000
Dear Ms. Green:
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.
