Intended Use

The Liverpool Radial Head Replacement Device is intended for: - 1) Replacement of the radial head for degenerative or post-traumatic disabilities presenting pain, creptation, and decreased motion at the radio-humeral and/or proximal radio-ulnar joint with: - a) Joint destruction and/or subluxation visible on x-ray - b) Resistance to conservative treatment - 2) Primary replacement after fracture of the radial head - 3) Symptomatic sequelae after radial head resection - 4) Revision following failed radial head arthroplasty The device is intended for single use with bone cement.

Device Description

The Biomet Liverpool Radial Head Replacement Device is a one-piece cobalt alloy device. The tapered stem is centered into the intramedullary canal of the radius. The articulating surface is a highly polished concave surface to articulate with the capitellum of the humerus. Except for the articulating surface, the device is roughened by a process called "Microbond" Coating. The device is available in two sizes, 16mm and 18mm. The 16mm device has a stem length of 32.76mm and head heights that vary from 14 to 24mm. The 18mm device has a stem length of 32.76mm and head heights that vary from 14 to 24mm.

AI/ML (Artificial Intelligence / Machine Learning)

No
The device description and intended use describe a mechanical implant for joint replacement, with no mention of software, algorithms, or data processing that would indicate AI/ML technology.

Therapeutic

Yes
The device is a radial head replacement intended to treat degenerative or post-traumatic disabilities, fractures, and failed arthroplasties, which are therapeutic intentions.

Diagnostic

No

The device is a radial head replacement, designed for therapeutic intervention (replacing a damaged radial head) rather than for diagnosing conditions.

SaMD (Software as a Medical Device)

No

The device description clearly states it is a "one-piece cobalt alloy device" and describes its physical characteristics and sizes, indicating it is a physical implant, not software.

IVD (In Vitro Diagnostic)

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

• IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
• Device Description and Intended Use: The Liverpool Radial Head Replacement Device is a physical implant designed to replace a damaged radial head in the human body. It is used in surgical procedures based on clinical symptoms and imaging (x-ray). It does not analyze biological samples.

The information provided clearly describes a surgical implant, not a device used for testing biological specimens outside the body.
