Comparing two methods of shoulder joint replacement for stability

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the stability of two different techniques for reverse shoulder arthroplasty: metallic lateralization (MIO-RSA) and bony lateralization (BIO-RSA). Patients with shoulder osteoarthritis and significant glenoid medialization will be randomized to receive either procedure. The study will utilize CT-based motion analysis to assess the 3-dimensional migration patterns of the glenoid components over a two-year period post-surgery. The goal is to determine if the new metallic approach is as stable as the traditional bony method.
