Quantitative measures of the trabecular structure for each of the four locations. (a) Trabecular thickness (Tb.Th*). (b) Structure model index (SMI). (c) Trabecular spacing (Tb.Sp*). (d) Trabecular number (Tb.N*). Cores from the lesion area exhibited the highest Tb.Th* but lowest SMI. Differences in trabecular structure were also noted between the matched and medial locations. Each bar represents the mean, and error bars represent one standard deviation. *Significant differences between groups (P < 0.05). #A trend (0.05 ≤ P < 0.10).
