Comparing two types of reverse shoulder arthroplasty for rotator cuff issues

Clinical Study to Analyze the Functional, Radiological, and Strength Results in Lateralized Models and Inverted Arthroplasty Medializations

Not applicable Interventional Hospital San Carlos, Madrid · NCT05847062

This study is testing two different types of shoulder surgeries to see which one helps older patients with rotator cuff problems feel and move better after their treatment.

What this trial studies

This clinical trial aims to evaluate the functional outcomes, complications, and muscle performance associated with two different reverse shoulder arthroplasty systems: one with a medialized center of rotation and the other with a lateralized center of rotation. It is a prospective, unblinded, randomized, comparative trial involving patients over 65 years old who have rotator cuff arthropathy that has not improved with conservative treatment. Participants will be randomly assigned to one of the two groups, and their outcomes will be measured using the Constant scale to determine any significant differences in performance. The study seeks to enroll a total of 42 patients to ensure adequate statistical power for the analysis.

Who should consider this trial

Good fit: Ideal candidates are male or female patients over 65 years old with rotator cuff arthropathy that has not responded to conservative treatment for at least six months.

Not a fit: Patients with specific conditions such as rheumatoid arthritis, avascular necrosis, or significant glenoid bone defects may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and rehabilitation for patients with rotator cuff arthropathy.

How similar studies have performed: While this approach is based on existing concepts, the specific comparison of medialized versus lateralized centers of rotation in reverse shoulder arthroplasty is relatively novel.
