Comparing two types of shoulder replacement surgeries

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 aims to compare the outcomes of two different reverse shoulder arthroplasties: a conventional reverse shoulder arthroplasty (RSA) and a lateralized version known as BIO-RSA. The study will assess the functional results and complications experienced by patients after two years of surgery. By lateralizing the center of rotation in the BIO-RSA, researchers hope to improve range of motion and stability while reducing complications such as scapular notching. The trial will involve 130 patients across four hospitals, providing valuable insights into the best treatment options for shoulder osteoarthritis and related conditions.
