Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who are scheduled for primary reverse total shoulder arthroplasty.

Probably not a fit

Patients who have had prior coracoid transfer procedures or are undergoing revision surgery from a previous arthroplasty may not benefit from this study.

What this trial studies

This study evaluates the effectiveness of prophylactic conjoint tendon lengthening during reverse shoulder arthroplasty to prevent or reduce anterior shoulder pain one year post-surgery. Reverse shoulder arthroplasty is performed to treat severe shoulder arthritis and involves reversing the ball and socket of the shoulder joint. The study aims to address the issue of persistent anterior shoulder pain that some patients experience after the procedure, potentially caused by increased tension on the conjoint tendon. By lengthening this tendon, the researchers hope to alleviate pain and improve patient outcomes.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of persistent shoulder pain in patients undergoing reverse shoulder arthroplasty.

How similar studies have gone: While the specific approach of conjoint tendon lengthening is novel, reverse shoulder arthroplasty has shown success in improving shoulder function and pain relief in other studies.
