Bone three-dimensional microstructural features of the common osteoporotic fracture sites

Figure 1 The trabecular bone mineral density of the thoracic and lumbar vertebrae[22]. The bone mineral density tends to decrease from the first thoracic to third lumbar vertebra.

Figure 2 Micro-computed tomography image in different regions of vertebral body[25]. A: Anterosuperior; B: Anteroinferior; C: Central; D: Posterosuperior; E: Posteroinferior regions. The trabecular bone is lower in the anterosuperior and central regions.

Figure 3 Scanning electron microscopic image of vertebral trabecular bone[25]. The microcallus (MC) is seen on the vertical trabecula (A). Tertical trabeculae are relatively thicker than the horizontal ones (B).

Figure 4 Trabecular microstructure of femoral neck from a man aged 62 years (A), a man aged 92 years (B), a woman aged 62 years (C), and a woman aged 92 years (D)[49]. The trabecular bone is higher in a man aged 62 years and is lower in a woman aged 92 years.

Figure 5 Three D reconstructed images of the canal networks in the inferior femoral neck cortex from a man aged 62 years (A), a man aged 92 years (B), a woman aged 62 years (C), and a woman aged 92 years (D)[49]. There are more enlarged canals in the 92 years than those of the 62 years.
