Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults undergoing pre-operative care for reverse shoulder arthroplasty on a native shoulder joint.
✕Probably not a fit
Patients under 18, those unable to provide informed consent, or those refusing to participate will not benefit from this study.

What this trial studies
This study aims to analyze the positioning of the scapula in patients undergoing reverse shoulder arthroplasty by comparing its position in standing and supine positions using a portable ultrasound system. Patients will have a localizer ultrasound performed during their surgical consultation or the day before surgery, with the goal of obtaining three-dimensional data on scapular positioning. The study is mono-centered and focuses on patients who are already in the pre-operative care process for shoulder surgery.
Why it matters
Potential benefit: If successful, this study could improve surgical outcomes by providing better understanding of scapular positioning in relation to shoulder arthroplasty.
How similar studies have gone: While this approach is innovative, similar studies have not been widely reported, indicating this may be a novel exploration in scapular positioning.
