Vancomycin concentration in vancomycin and vancomycin microsphere groups. a Local vancomycin in vancomycin group was highest at 12 h with a concentration of 148 μg/ml and dropped to 1.2 μg/ml quickly at 24 h. b In vancomycin microsphere group, the release of vancomycin (VR) was highest at 24 h and maintained a concentration of 3.0 μg/ml after 72 h. The concentration of vancomycin remaining in the microsphere (VM) dropped constantly
