Eligibility Criteria
-----------------
Inclusion Criteria:(Key) Both genders; Age ≥ 18 years old; Full skeletal maturity; Life expectancy over 5 years; Patient is requiring primary unilateral arthroplasty based on physical examination and medical history; Good bone quality evaluated by the Investigator and the intraoperative evaluation; A diagnosis in the target shoulder of one or more of the S-11 SMR TT Hybrid Glenoid and Cementless Finned Short Stem Version Sep 2021 2.0 Confidential Page11 following: Primary osteoarthritis; Secondary osteoarthritis; Post-traumatic arthritis; Rheumatoid arthritis; Avascular necrosis acute fractures of the humeral head that cannot be treated with other fracture fixation methods; cuff tear arthropathy (only in combination with CTA Heads); Glenoid arthrosis without excessive glenoid bone loss: A1, A2 and B1 according to Walch classification. Exclusion Criteria (Key): Patient requiring revision shoulder arthroplasty; Osteoporosis with a history of non-traumatic fractures; Steroid injections within the previous 3 months; Contralateral shoulder replacement within the previous 3 months; Significant proven or suspicious infection of the target shoulder or any serious infectious disease before the study according to the Investigator; Significant neurological or musculoskeletal disorders that may compromise functional recovery; Not recovered axillary nerve palsy; Non functioning deltoid muscle; Known or suspicious hypersensitivity to the metal or other components and materials of the implant; Participation in any experimental drug/device study within the 6 months prior to the preoperative visit; Women of childbearing potential who are pregnant, nursing, or planning to become pregnant.

The glenoid components when used as part of an anatomic shoulder replacement are intended for cemented fixation.<br>|
| SMR TT Hybrid Glenoid with Cementless Finned Short Stem<br>Patients implanted with SMR TT Hybrid Glenoid with Cementless Finned Short Stem | Device: SMR TT Hybrid Glenoid with Cementless Finned Short Stem<br>* The subject SMR Hybrid Glenoid System and SMR cementless finned short stem is intended for both primary or revision anatomic and reverse shoulder joint replacement. The glenoid components when used as part of an anatomic shoulder replacement are intended for cemented fixation. The fins are intended to enhance press-fit fixation. The same proximal morse taper is used for coupling to the same humeral bodies in the SMR Shoulder System. The SMR finned short stem is intended for cementless fixation.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of patients reaching a clinical progression from baseline to 24-month follow-up | The primary endpoint consists of the proportion of patients reaching a clinical progression from baseline to 24-month follow-up measured as: Constant score improvement of greater than 10; Adjusted Constant score greater than or equal to 54. | 24 Months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Measure American Shoulder and Elbow Surgeons Shoulder Score (ASES) | The ASES questionnaire is composed of both a physician-rated component and a patient-reported component. The patient questions focus on joint pain, instability, and activities of daily living. Scores range from 0 to 100 with a score of 0 indicating a worse shoulder condition and 100 indicating a better shoulder condition. | Baseline to 24 and 60 Months | 
| Measure Oxford shoulder score | Oxford Shoulder Score (OSS) is a 12-item patient-reported PRO specifically designed and developed for assessing outcomes of shoulder surgery. | Baseline to 24 and 60 Months | 
| Measure Constant Score | The Constant-Murley score (CMS) is a 100-points scale composed of a number of individual parameters. These parameters define the level of pain and the ability to carry out the normal daily activities of the patient. The higher the score, the higher the quality of the function. | Baseline to 24 and 60 Months | 
| Measure Simple Shoulder Test | Simple Shoulder Test (SST) is a series of 12 yes or no questions the patient answers about the function of the involved shoulder. The answers to these questions provides a standardized way of recording the function of a shoulder before and after treatment. The difference between the shoulder function before treatment and after the recovery period is the effectiveness of the treatment. | Baseline to 24 and 60 Months | 
| Measure Patient Satisfaction | The satisfaction of the patients with regard to the effectiveness of the prosthetic treatment is graded on a scale from 1 to 5 | Baseline to 24 and 60 Months | 
| Stability of the SMR TT hybrid glenoid component with or without SMR cementless finned short stem | Rate of symptomatic radiolucent lines, loosening and subsidence ≥2 mm | Immediately postoperative to 24 Months | 
| System conversion rate, intended as a conversion within the SMR system from anatomic to reverse | The SMR shoulder system is a modular system and in case of evolution of the pathology it may be easily converted from one configuration to another. | 24 Months | 
| Failure rate, intended as removal of the SMR TT hybrid glenoid component | A removal of the glenoid component is intended as a revision and a failure of the implant. | Immediately postoperative to 24 Months | 
| Failure rate, intended as removal of the SMR cementless finned short stem | A removal of the stem component is intended as a revision and a failure of the implant. | Immediately postoperative to 24 Months | 
| Incidence of device-related AE/SAE (ADE/SADE) | Device Related Adverse Events/Serious Adverse Events, device deficiencies, malfunctions and use errors at all follow-up time points | Immediately postoperative to 24 and 60 Months | 
| Survival rate (Kaplan-Meier) |  | 60 Months |
