Background: The use of vancomycin powder in spine surgery has been supported in adult populations, however, its efficacy in preventing postoperative surgical site infections in AIS patients is yet to be determined.
Methods: A multi-center review was conducted from June 2010 to February 2019, using ICD and CPT codes to identify AIS patients who underwent primary PSF. The patients were divided into two groups: the vancomycin cohort (receiving local vancomycin powder prior to wound closure) and the non-vancomycin cohort.
