The study is a multicenter, 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 2.0 Fracture System (Implants and Instrumentation) when used for fracture shoulder arthroplasty. 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.
