Figure 1. Radiographs and histological findings for infarcted femoral heads.

Micro-CT scan images of infarcted femoral heads by groups. Femoral heads showed significantly lower trabecular bone in the HFD-AVN and HFD-AVN-LacZ groups compared with the NCD-AVN group; the trabecular networks were preserved in the HFD-AVN-Leptin group. ROIs (solid red lines) of groups were cross-sectional areas of the middle of femoral heads (dotted red lines).
