The goal of this study is to confirm the safety and performance of the AETOS Shoulder System for USA adoption. This is a prospective, open, adaptive, non-comparative, multi-centre investigation enrolling a maximum of 220 subjects in 2 cohorts (anatomic and reverse) at up to 15 sites. No intra-study comparator group will be included, and there will be no randomization
This study will confirm the safety and performance of the AETOS Shoulder System in anatomic and reverse TSA. Revisions will not be enrolled into this study. The AETOS Shoulder System is manufactured by Smith \& Nephew, Inc., 1450 Brooks Road Memphis, Tennessee 38116 USA, and has been 510k Cleared as of 07Jun2023; therefore, it is considered a post-market product and will be procured through normal commercial channels in the USA. The humeral stem is designed to be used for both Total Shoulder Arthroplasty (TSA) and reverse shoulder arthroplasty procedures. The humeral stems are designed with fins and a porous plasma coating to provide fixation within the proximal humeral metaphysis.

American Shoulder and Elbow Score (ASES)
The ASES instrument is composed of 2 sections containing participant self-reported and clinician assessments. The ASES score is a 0 to 100-point rating with a higher score indicating improvement in pain and function.
Time frame: 6 months, 1 year, 2 years, and 5 years
Constant Murley Score
Constant-Murley Shoulder (CMS) scale assesses four aspects related to shoulder pathology; two subjective: pain and activities of daily living (ADL) and two objective: range of motion (ROM) and strength. The subjective components can receive up to 35 points and the objective 65, resulting in a possible maximum total score of 100 points (best function). Pain and ADL are answered by the subject; ROM and strength require a physical evaluation and are answered by the orthopaedic surgeon or the physiotherapist.
Time frame: 6 months, 1 year, 2 years, and 5 years
Simple Shoulder Test (SST)
Series of 12 "yes" or "no" questions the patient answers about the function of the involved shoulder. The answer to these questions provides a standardized way of recording the function of a shoulder before and after treatment.
Time frame: 6 months, 1 year, 2 years, and 5 years
Single Assessment Numeric Evaluation (SANE)
The SANE is a simple, single-question, patient-based shoulder function assessment tool: ''How would you rate your shoulder today as a percentage of normal (0% to 100% scale with 100% being normal)?''
Time frame: 6 months, 1 year, 2 years, and 5 years
