Mechanical Properties and Elution Characteristics of Polymethylmethacrylate Bone Cement Impregnated with Antibiotics for Various Surface Area and Volume Constructs

Background Numerous studies have examined the elution characteristics and the effects of antibiotics from bone cement. this study seeks to determine the effect that surface area and volume have on the elution characteristics and bioavailability of tobramycin and vancomycin when mixed in polymethylmethacralate (PMMA) bone cement in various combinations. It also investigates the mechanical properties of antibiotic-impregnated bone cement and its relationship to surface area and volume.
