Correlation analysis of BMD in different regions of the vertebrae determined by QCT and DXA on pedicle screw loosening [PDF]
Scientific ReportsLow 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 ...
