MDR - Comprehensive Primary/Micro Stem & Versa-Dial Ti Humeral Head

The objective of this retrospective/prospective enrollment and prospective follow-up consecutive series PMCF study is to collect data confirming safety, performance and clinical benefits of the Comprehensive Primary Micro Stem and Comprehensive Anatomic Versa-Dial Titanium Humeral Heads when used for primary and revision total shoulder arthroplasty (implants and instrumentation) at 1,3,5,7 and 10 years\*. Comprehensive Primary Micro Stem and Comprehensive Anatomic Versa-Dial Titanium Humeral Heads have been on the market since 2007, but have insufficient data to support 10 years of clinical history. Therefore, a prospective aspect to the study will be utilized in order to collect long-term data.

The objective of this retrospective/prospective enrollment and prospective follow-up consecutive series PMCF study is to collect data confirming safety, performance and clinical benefits of the Comprehensive Primary Micro Stem and Comprehensive Anatomic Versa-Dial Titanium Humeral Heads when used for primary and revision total shoulder arthroplasty (implants and instrumentation) at 1,2,3,5,7 and 10 years\*. Comprehensive Primary Micro Stem and Comprehensive Anatomic Versa-Dial Titanium Humeral Heads have been on the market since 2007, but have insufficient data to support 10 years of clinical history. Therefore, a prospective aspect to the study will be utilized in order to collect long-term data.

The primary objective of this study 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 either implant or instrumentation should be specified.

The secondary objective is the assessment of performance and clinical benefits by recording patient-reported clinical outcomes measures (PROMs).

\*The most recent available data will be used. If any of the listed time points are not available, data will be used from last available time point and follow-up will move forward at the closest available time point.
