Biomechanical strength comparison of pedicle screw augmentation using poly-dicalcium phosphate dihydrate (P-DCPD) and polymethylmethacrylate (PMMA) cements
Abstract
A basic science, hypothesis-driven experimental study of the biomechanics of two bone cements in their ability to augment pedicle screws in bone foam. The purpose of our study was to compare the pullout and torque resistance of conventional pedicle screws (CPS) augmented with either polymethylmethacrylate (PMMA) or poly-dicalcium phosphate dihydrate (P-DCPD) cement in polyurethane foam blocks mimicking osteoporotic bone. P-DCPD cement has...
