Abstract

Study design Experimental, human cadaveric study.Objective To assess the fixation effects of injecting cement augmentation before screw insertion or after insertion of fenestrated screws; the effect of modulating cement viscosity; and the effects of these techniques on screw removal.Summary of backg...
