Pullout strength of pedicle screws augmented with particulate calcium phosphate: An experimental study
Abstract
BACKGROUND CONTEXT: Pressure-injected and in situ curing bone cements have been studied as alternatives in augmenting lumbar pedicle screw fixation but are frequently found to leak outside the confines of the target vertebra.
PURPOSE: The objective is set to determine the mechanical efficacy of a porous granular/particulate calcium phosphate (CP) bone augmentation product (Skelite) applied manually without pressurized injection in this …
