Sidus(TM) Post Market Clinical Follow-up (PMCF) Study

This study is a prospective, noncontrolled, multi-center post market clinical follow-up study involving orthopedic surgeons skilled in hemi and total shoulder arthroplasty procedures. A total number of 160 subjects will be included in the study. Ethics Committee (EC) approval for each site has to be obtained prior to conducting this study. Sequentially, all eligible patients will be offered study enrollment at each center to avoid potential selection bias. All potential subjects will be required to participate in an informed consent process and sign the EC approved written Informed Consent prior to study enrollment. The study is designed to be prospective to ensure that the study population is representative of the type of population that the device is intended to treat. Patients will be selected according to the subject selection criteria described in section 8. All subjects will undergo preoperative, intraoperative and immediate postoperative assessments including physical examinations, radiographic evaluations and collection of quality of life metrics. Follow-up evaluations are to be conducted at 3 and 6 months, 1, 2, 5, 7 and 10 years postoperation.
