Fig. 3From: In vitro elution characteristics of gentamicin-impregnated Polymethylmethacrylate: premixed with a second powder vs. liquid LyophilizationScanning electron microscope images of the surface of PMMA spacers (3a) LG-PMMA spacer; (3b) PG-PMMA spacer. The picture of the LG-PMMA spacer showed greater density of small uniformed, rounded shape pores; while the PG-PMMA spacer had a smoother surface areaBack to article page
