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

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.
