Figure 3. Effects of PLD on the cortical bone structure of femur midshaft. (A) The schematic diagram of the ROI of femoral midshaft and typical μCT images of cortical microarchitecture are displayed. Measurements are shown for (B) total, bone, and medullary tissue area, (C) periosteal and endosteal perimeters, (D) Ct.BV/TV and (E) Ct.Th. Data are expressed as mean ± S.D.; n=4 to 5 per group; *P < 0.05, vs. the Sham group; #P < 0.05, vs. the SCI group.
