Observational model: COHORT
Time perspective: PROSPECTIVE
Sampling method: PROBABILITY_SAMPLE
Study population: 80 subjects are to be enrolled in this clinical investigation. The clinical investigation has been designed to follow the surgeon's standard of care for joint arthroplasty subjects, which entails clinical evaluation on a regular ongoing basis, or as needed should the subject become symptomatic in the treated joint.

Brief summary: This investigation is a prospective, multicenter clinical investigation. It is anticipated that a total of eighty (80) subjects will be enrolled at approximately 4-7 sites. The clinical investigation has been designed to follow the surgeon's standard of care for joint arthroplasty subjects, which entails clinical evaluation on a regular ongoing basis, or as needed should the subject become symptomatic in the treated joint.

Detailed description: The objective of this clinical investigation is to demonstrate the safety and efficacy/performance of the ReUnion RSA System. Efficacy/performance of the procedure will be measured the American Shoulder and Elbow Surgeons (ASES) Shoulder Score. Safety of the ReUnion RSA System will be demonstrated through reporting of device-related intra-operative and post-operative Adverse Events (AEs). Enrolled subjects will be assessed at Pre-Operative, Operative/Discharge, and at 6 Weeks, 6 Months, 12 Months, 24 Months and annually thereafter up to 10 years following the index procedure.

Eligibility criteria: Inclusion Criteria:

* Subject is willing to sign the informed consent.
* Subject is willing and able to comply with postoperative scheduled clinical and radiographic evaluations.
* Subject is male or non-pregnant female and 18 years or older at the time of surgery.
* Subject's joint has gross rotator cuff deficiency, a functional deltoid muscle and is anatomically and structurally suited to receive the implant and subject has one or more of the following:

  * Painful, disabling joint disease of the shoulder resulting from degenerative arthritis or rheumatoid arthritis
  * Failed previous shoulder joint replacement

Exclusion Criteria:

* Subject has an active or suspected latent infection in or about the shoulder joint.
* Subject has mental or neuromuscular disorder which would create an unacceptable risk of prosthesis instability, prosthesis fixation failure or complications in postoperative care.
* Subject has bone stock compromised by disease, infection or prior implantation which cannot provide adequate support and/or fixation to the prosthesis.
* Subject has anticipated activities which would impose high stresses on the prosthesis and its fixation.
* Subject is obese such that he/she produces a load on the prosthesis which can lead to failure of fixation of the device or to failure of the device itself.
* Subject has concomitant disease(s) which may significantly affect the clinical outcome.
* Subject has traumatic or pathologic fracture of the proximal humerus
