Fig. 5From: Analysis of trabecular bone microstructure in osteoporotic femoral heads in human patients: in vivo study using multidetector row computed tomographyTrabecular separation (Tb.Sp) in the proximal head and neck. a The Tb.Sp in the apical area was significantly lower in ROI 1 than in ROI 2 and ROI 3, and was significantly lower in ROI 2 than in ROI 3. b The Tb.Sp in ROI 6 was significantly lower than in the other ROIs in the neck area. *p < 0.05, **p < 0.01Back to article page
