Study Endpoints

Primary Endpoints

Number of Participants With Deep Surgical Site Infection (SSI)
within 182 days of definitive fracture fixation surgery

Compare the proportion of deep SSIs of the study injury within 182 days of definitive fracture fixation surgery in patients treated with local Vancomycin powder compared to those treated with a combination of local Vancomycin and Tobramycin powders. For this study a "deep SSI" is a SSI that is treated with operative debridement. In the current CDC terminology this would include all deep organ space, deep incisional, and superficial infections that are treated with surgery.
