AETOS Shoulder System

Study Purpose

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

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over
Gender All

    Exclusion Criteria:

    Patients who meet any of the following criteria will not qualify for participation in the trial: 1.
Patient has a contraindication to AETOS. 2. Patient is undergoing a revision shoulder replacement surgery including total or partial arthroplasty. 3. Patient is indicated for a Hemiarthroplasty. 4. Patient has traumatic injury or a fracture. 5. Patient has uncontrolled diabetes with a hemoglobin A1C of 7.5 or greater. 6. Patient has comorbidities/conditions that preclude proper healing/fixation of the implant. 7. Patient has poor quality or insufficient bone stock to support the implant. 8. Patient has poor bone quality where there could be considerable migration of the implant and/or a chance of fracture. 9. Patient has rapid joint destruction, marked bone loss or bone resorption (e.g., severe osteoporosis). 10. Patient has osteomalacia. 11. Patient has muscular, neurologic, or vascular deficiencies that may compromise the outcome of the shoulder replacement surgery. 12. Patient has a known sensitivity, allergic reaction, and/or known allergies to one or more of the implanted materials. 13. Patient has a distant foci of infection which may spread to the implant site, active local or systemic infection, sepsis, or osteomyelitis. 14. Patient has an elevation of sedimentation rate, elevation of WBC count, or marked shift in WBC differential count unexplained by other disease. 15. If reverse shoulder arthroplasty, patient has a non-functional deltoid or external rotator muscles. 16. If reverse shoulder arthroplasty, patient has a significant injury to the upper brachial plexus. 17. If reverse shoulder arthroplasty, patient has paralysis of the axillary nerve. 18. Patient is uncooperative, has a neurologic disorder and is not capable of following directions, or is a vulnerable subject per ISO 14155 (i.e., individuals who are unable to fully understand all aspects of the investigation that are relevant to the decision to participate, or who could be manipulated or unduly influenced as a result of a compromised position, expectation of benefits or fear of retaliatory response). 19. Patient is pregnant or plans to become pregnant during the follow-up period. 20. Patient has a Body Mass Index (BMI) of >35kg/m2 or a BMI that may compromise the outcome of the shoulder replacement surgery. 21. Patient has anticipated activities which would impose high stresses on the implant and its fixation or has a high likelihood of a fall. 22. Patient is a known smoker, vaper, alcohol abuser, or drug abuser within 180 days of consent. 23. Patient has participated previously in this clinical trial and was withdrawn. 24. Patient is participating in another device or drug trial or observational competitive study.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

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.
