The ReUnion RFX System includes a Reversible Fracture Stem) that can utilize either the ReUnion Total Shoulder Arthroplasty (TSA) or ReUnion Reverse Shoulder Arthroplasty (RSA) humeral and glenoid components and is indicated for use a hemi, total or reverse shoulder replacement. The ReUnion RFX stem is intended use only.

When used with ReUnion TSA Humeral & Glenoid Components
The ReUnion RFX System, when used with ReUnion TSA Humeral and Glenoid components, is indicated for use as a Hemi or Total Shoulder Replacement:

• · Aseptic necrosis of the humeral head.
• · Painful, disabling joint disease of the shoulder resulting from: degenerative arthritis, or posttraumatic arthritis.
• · Proximal humeral fractures and/or dislocation.
• · Clinical management problems where arthrodesis or alternative techniques are less likely to achieve satisfactory results.
• · Revision of previous unsuccessful total shoulder replacement, resurfacing or other procedure.
  In the case of revision, when ReUnion RFX humeral stems are well fixed, the system is indicated for conversion to a total shoulder arthroplasty. 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 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 failed joint replacement with a grossly deficient rotator cuff. The patient must have a functional deltoid muscle, and be anatomically suited to receive the implant(s).
  Glenoid Baseplate components are intended for cementless use with the addition of screw fixation.

This Traditional 510(k) submission is being supplied to the U.S. FDA to provide authorization to market additional components to the ReUnion RSA, TSA and RFX Systems, previously cleared via K172210.

ReUnion Reversible Fracture System (RFX)
The ReUnion Reversible Fracture System consists of a humeral fracture stem component which may be used in conjunction with TSA or RSA humeral and glenoid components for conventional total shoulder arthroplasty or reverse shoulder arthroplasty. It may also be used in conjunction with TSA humeral components to articulate directly with the anatomic glenoid in a hemi-shoulder application. The device contains various number of suture holes. The stems have a female taper on the proximal end of the shaft to accept TSA and RSA Gleno-humeral components. It is designed to be used in cemented applications only.

ReUnion Reverse Shoulder Arthroplasty System (RSA)
The ReUnion RSA Shoulder System is a system of components intended for total shoulder replacement in a reverse shoulder configuration. The system is comprised of a humeral cup, humeral insert, glenosphere, glenoid baseplate and screws. The Humeral Cup with the Humeral Insert are attached to the humeral side of the joint via the ReUnion TSA Humeral Stem while the Glenosphere is implanted with the Glenoid Baseplate onto the glenoid side of the joint fixated with locking Center and Peripheral Screws.

ReUnion Total Shoulder Arthroplasty System (TSA)
The Reunion Total Shoulder Arthroplasty (TSA) System is intended for shoulder arthroplasty. The components of this system consist of humeral stems, a modular humeral neck adapter, single radius humeral heads, and self-pressurizing glenoids (SPG). The humeral stem is offered in both cemented and cementless designs. The cementless humeral stem design features a circumferential Ti-plasma spray and hydroxyapatite (HA) coating at the proximal end and the cemented humeral stems have no coating at the proximal end. These humeral stems were designed to mate with the subject single radius humeral heads or the modular neck adapter, for compatibility with other marketed humeral heads. The self-pressuring glenoids (SPG) mate with the single radius heads. The SPGs are offered in both pegged and keeled configurations.

I am sorry, but the provided text does not contain any information about acceptance criteria or a study that proves a device meets such criteria. The document is a 510(k) premarket notification clearance letter from the FDA for several shoulder arthroplasty systems, along with their indications for use and a summary of technologies. It explicitly states that "Non-clinical laboratory testing was not required for this submission" and "Clinical testing was not required for this submission."

Therefore, I cannot provide the requested table, sample sizes, expert details, adjudication methods, or information about MRMC or standalone studies.
