Total Shoulder Arthroplasty Multi-Center Registry

The study is a non-randomized multi-center prospective registry and subjects will be treated
according to standard of care at each center. Subjects will be approached for participation
in this study after they have made the decision to undergo a primary or revision shoulder
arthroplasty procedure. The treating surgeon will obtain verbal consent from the patient for
a research coordinator to screen for eligibility. Patients who meet all criteria will be
offered enrollment into the study. The total enrollment goal is a minimum of 500 anatomic
shoulder arthroplasty and 500 reverse shoulder arthroplasty subjects enrolled in the
multi-center registry.

therapy.

2. Patient is between the ages of 18 and 100 years.

3. An advanced pre-operative image (CT or MRI) has been acquired

4. Subject has failed 6 months of conservative treatment, unless acute humeral fracture,
and will be surgically treated with a primary or revision implantation of an anatomic
or reverse shoulder prosthesis system manufactured by Arthrex.

Exclusion Criteria:

1. Patient has known intentions, obligations, or co-morbidity that would inhibit them
from participating in the study

2. The patient has known co-morbidity that would make the subject ineligible for a
shoulder arthroplasty procedure

3. Patient declines participating in the study
