Examining testosterone levels and skin bacteria in shoulder surgery patients

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 observational study investigates the relationship between serum testosterone levels and the presence of Cutibacterium bacteria in patients undergoing shoulder arthroplasty. In the first phase, blood samples and skin swabs are collected from 51 patients before and during surgery to analyze testosterone levels and bacterial load. The second phase aims to assess whether preoperative testosterone levels correlate with the risk of periprosthetic joint infection and bacterial load in deep tissue cultures during revision surgeries. The study seeks to enhance understanding of how testosterone may influence surgical outcomes.
