OBJECT Instrumentation of the osteoporotic spine can be fraught with complications such as hardware failure. A cadaver study was performed to determine the biomechanical performance of polymethylmethacrylate (PMMA)-augmented pedicle screws. METHODS Three osteoporotic human cadaveric specimens with a mean bone mineral density of 0.70 g/cm2 were used to(More)
OBJECTIVE Instrumentation of the osteoporotic spine may result in bone failure because of pedicle screw loosening and pullout. A clinical evaluation of a novel fenestrated bone tap used in pedicle screw augmentation was performed to determine the performance and safety of this technique. METHODS Over a 2.5-year period, the clinical and radiographic(More)
