Morphology of PMMA/gelatin/antibiotic constructs characterized by A) SEM (scale bars represent 200 µm) and B) microCT (scale bars represent 2 mm, the porosity is indicated at upper left): a porous structure was created by the incorporation of gelatin microparticles; the bulk porosity is controlled by both the percent of gelatin incorporated and the weight ratio of drug solution versus gelatin for swelling.
