Table 2.
Trabecular architecture of the humerus and femur is sculpted during fetal development, i.e. trabecular thickness (Tb.Th) increases whilst number (Tb.N) decreases and volume fraction (BV/TV) remains constant. Age categories compared vs. 4 months using one-way anova with Tukey’s post-hoc. Grey text indicates non-significant difference in architecture.
