What to Expect as a Participant

This is an observational study. You will not receive an experimental treatment; researchers will collect data based on your existing condition or standard treatment.

This trial targets 40 participants in total. It began in 2022-04-22 with a primary completion date of 2033-07-16.

Brief Summary

The study is a monocentric, retrospective and prospective, non-randomized, non-controlled and consecutive series post-market study. The purpose of this study is to collect long-term data confirming safety, performance and clinical benefits of the Anatomical Shoulder Bipolar System (Implants and Instrumentation) when used as a salvage solution in shoulder replacement. The primary objective is the assessment of safety by analyzing implant survivorship. This will be established by recording the incidence and frequency of revisions, complications and adverse events. Relation of the events to implant, instrumentation and/or procedure should be specified. The secondary objective is the assessment of performance and clinical benefits by recording patient-reported clinical outcome measures (PROMs) as well as radiographic outcomes.

Eligibility Criteria

Inclusion Criteria: 1. The Anatomical Should Bipolar Adaptor is indicated for hemi shoulder replacement as a salvage solution in situations, where a Zimmer Anatomical Shoulder Inverse/Reverse prosthesis was originally planned, but it is intra-operatively found that the attachment of the Zimmer Anatomical Shoulder Inverse/Reverse glenoid fixation is not possible 2. Patient should have received the Anatomical Shoulder Bipolar System 3. Patient should have signed the Informed Consent Form 4. Patient is 18-100 years of age, inclusive 5. Patient is skeletally mature Exclusion Criteria: 1. Patients who are not willing to return for study required follow-up visits and/or are not willing to comply with the follow-up schedule 2. Patients who have any condition which would in the judgement of the Investigator place the patient at undue risk or interfere with the study. Any patient who is institutionalized, or is a known drug abuser, a known alcoholic or anyone who cannot understand what is required of them 3. Patient is known to be pregnant or breastfeeding 4. Musculoskeletal situation that enables the application of a regular hemi or total shoulder system 5. Good quantity or quality of the glenoid bone, where the fixation of a Zimmer Anatomical Shoulder Inverse/Reverse glenoid fixation is possible 6. Patient's physical conditions that would impair achieving adequate implant support, and/or prevent the use of an appropriately sized implant (e.g. due to insufficient quality or quantity of bone). 7. Signs of infection 8. Non-functional deltoid muscle 9. Charcot's shoulder (neuroarthropathy) 10. Presence of significant injury to the upper brachial plexus 11. Any neuromuscular or vascular disease compromising the affected limb that would endanger the success of the intervention
