Reducing Cutibacterium Acnes in Shoulder Surgery

Official title: Optimization of Skin Preparation to Reduce Cutibacterium Acnes Colonization in Superficial and Deep Samples During Prosthetic Shoulder Surgery in Male Patients

Run by Nantes University Hospital · NCT04028401 · Data updated 2026-11-12

This study is testing if using a benzoyl peroxide cream on the skin for five days before shoulder surgery can help reduce a bacteria that may cause infections in men having shoulder operations.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adult male patients scheduled for shoulder arthroplasty without prior surgeries on the same shoulder.

Probably not a fit

Patients with a history of shoulder surgery, acute trauma, or certain medical conditions such as cancer or immunosuppression may not benefit from this study.

What this trial studies

This clinical trial aims to evaluate the effectiveness of applying a 5% benzoyl peroxide topical treatment on the skin before shoulder surgery to reduce the presence of Cutibacterium acnes, a bacterium linked to post-operative infections. The study focuses on male patients undergoing various types of shoulder arthroplasty for conditions like osteoarthritis or rotator cuff tears. By applying the treatment for five days prior to surgery, the researchers hope to decrease the bacterial load in the surgical area, potentially improving surgical outcomes. The trial is interventional and is currently in Phase 3.

Why it matters

Potential benefit: If successful, this approach could significantly lower the risk of post-operative infections in male patients undergoing shoulder surgery.

How similar studies have gone: While the specific application of benzoyl peroxide in this context may be novel, similar studies have shown that optimizing skin preparation can reduce infection rates in surgical settings.
