No
The document describes a mechanical shoulder arthroplasty system and its components. There is no mention of software, algorithms, or any technology that would suggest the use of AI or ML. The focus is on the physical design and intended use of the implants.
Yes
The device is a shoulder replacement system (hemi, total, or reverse shoulder replacement) intended to treat various painful and disabling joint diseases, trauma, and as a revision for failed previous procedures, which constitutes therapeutic intervention.
No
The device description clearly states that these are components for shoulder replacement (arthroplasty) systems, intended for surgical implantation, not for diagnosing conditions.
No
The device description explicitly details physical components like humeral stems, glenoid components, screws, etc., which are hardware implants for shoulder arthroplasty. There is no mention of software as the primary or sole component.
Based on the provided text, 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, or tissue) to provide information for diagnosis, monitoring, or screening.
- Device Description: The text clearly describes the ReUnion RFX System, ReUnion RSA System, and ReUnion TSA System as implants used for shoulder replacement surgery. These are physical devices surgically placed within the body to replace or repair damaged joints.
- Intended Use/Indications for Use: The indications for use all relate to treating conditions of the shoulder joint through surgical implantation, such as aseptic necrosis, arthritis, fractures, and revisions of previous surgeries. None of the indications involve testing biological samples.
Therefore, the ReUnion RFX System and its related components are medical devices (specifically, orthopedic implants), but they do not fit the definition of an In Vitro Diagnostic device.

In conjunction with ReUnion TSA humeral and glenoid components, if the natural glenoid provides sufficient bone stock, ReUnion RFX humeral stems can be converted from a hemiarthroplasty to a total shoulder arthroplasty, as well as revised from an existing total shoulder arthroplasty to a secondary total shoulder arthroplasty. It is also indicated for conversion to a hemiarthroplasty. In conjunction with ReUnion TSA humeral components, ReUnion RFX humeral stems can be converted from a total or reverse shoulder arthroplasty to a hemiarthroplasty, as well as revised from an existing hemiarthroplasty to a secondary hemiarthroplasty, in treatment of previously failed shoulder arthroplasty cases where revision to a reverse shoulder arthroplasty is inappropriate.
The glenoid components are intended for cemented use only.
When used with ReUnion RSA Humeral & Glenoid Components
The ReUnion RFX System, when used with ReUnion RSA humeral & glenoid components, is intended for primary, fracture, or revision total shoulder replacement. The patient's joint must have gross rotator cuff deficiency, a functional deltoid muscle, and be anatomically and structurally suited to receive the implant(s).
• Painful, disabling joint disease of the shoulder resulting from degenerative arthritis or rheumatoid arthritis;
- Proximal humeral fractures
- · Revisions of previously failed shoulder joint replacements
In the case of revision, when ReUnion RFX humeral stems are well fixed, the system is indicated for conversion to a reverse shoulder arthroplasty. In conjunction with ReUnion RSA humeral and glenoid components, ReUnion RFX humeral stems can be converted from a hemi or total shoulder arthroplasty to a reverse shoulder arthroplasty, as well as revised from an existing reverse shoulder arthroplasty to a secondary reverse shoulder arthroplasty, in treatment of a grossly deficient rotator cuff with severe arthropathy or previously failed joint replacement with a grossly deficient rotator cuff. The patient must have a functional deltoid muscle, and be anatomically and structurally suited to receive the implant(s).
Glenoid Baseplate components are intended for cementless use with the addition of screw fixation.
