NCT03115177

Brief Summary

The purpose of this study is to investigate antibiotic treatment to target bacteria about the shoulder. This bacteria, Propionibacterium acnes, is detected in many revision shoulder surgeries and is thought to contribute to periprosthetic joint infections, pain, and failure of total shoulder arthroplasty as well as other shoulder surgeries. This study is investigating adding an FDA approved antibiotic that is commonly used for treatment of this bacteria and many common infections. The investigators will take intraoperative cultures to look for the presence or absence of specific bacteria. The investigators are conducting this trial to see if adding another antibiotic to specifically target this common bacteria found around the shoulder will be effective.

Outcome Measures

Primary Outcomes (1)

  • Bacterial Culture

    Intraoperative cultures will be taken from all study participants and tested for detection of bacteria. These cultures were held for 14 days and tested for aerobic and anaerobic bacteria. Reported data are presented for the number of participants with a positive bacteria culture from the intraoperative samples.

    2 weeks

Study Arms (2)

Cefazolin

ACTIVE COMPARATOR

All patients will receive standard perioperative antibiotics with 2g of cefazolin within 1 hour of incision. The control group will not receive any further antibiotic treatment.

Drug: Cefazolin
