Correlation analysis of BMD in different regions of the vertebrae determined by QCT and DXA on pedicle screw loosening

Abstract Low bone mineral density (BMD) impairs the stability of the bone-screw interface, which leads to screw loosening after spinal instrumentation. Quantitative computed tomography (QCT) and dual-energy X-ray absorptiometry (DXA) were applied to measure BMD of screw trajectories and other region...
