Eligible participants will receive preoperative intraosseous vancomycin (500 mg in 100 mL saline) as part of standard perioperative infection prophylaxis. The study is open-label due to the nature of the intervention. Blood samples will be collected at predefined time points intraoperatively to measure serum vancomycin concentrations.
