Measuring shoulder angles in patients after shoulder replacement surgery
Determination of Scapulothoracic and Glenohumeral Angles by Imaging in Patients After Shoulder Arthroplasty
This study is testing how shoulder angles change after reverse shoulder replacement surgery to see how well the surgery works and if there are any complications.

What this trial studies
This study aims to assess the scapulothoracic and glenohumeral angles in patients who have undergone reverse total shoulder arthroplasty. It involves imaging techniques, specifically the EOS exam, to evaluate the anatomical changes and potential complications following the surgery. Patients will also complete questionnaires to provide functional assessments of their shoulder. The goal is to better understand the long-term outcomes and stability of reverse shoulder prostheses.
Who should consider this trial
Good fit: Ideal candidates are patients who have had reverse total shoulder arthroplasty performed by Dr. Lionel Neyton at least 24 months prior to the study.
Not a fit: Patients with contraindications to the EOS examination or those with a history of significant shoulder injuries or surgeries may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved understanding of shoulder prosthesis performance and better patient outcomes in terms of mobility and stability.
How similar studies have performed: While similar studies have explored shoulder arthroplasty outcomes, this specific approach using EOS imaging for angle determination is relatively novel.
