Comparison of immediate anchoring effectiveness of two different techniques of bioresorbable ceramic application for pedicle screw augmentation
Background: The application of a bioresorbable calcium sulfate/hydroxyapatite (CaS/HA) ceramic at the interface of fenestrated screws and osteoporotic bone significantly enhances the immediate mechanical anchorage compared with non-augmented controls. However, the anchoring effectiveness of different screw augmentation techniques in spines with varying vertebral bone mineral density (BMD) remains
