From: Correlation of bone density to screw loosening in dynamic stabilization: an analysis of 176 patients
Mean HU values for the L3–5 pedicles excluding the cortical bone were insignificantly lower in the loosened screws compared to the intact screws. (238.48 ± 114.90 vs. 240.51 ± 108.91, p = 0.88).
