Figure 4 Result of the VFA examination in the thoracic and lumbar spine. The table shows individual vertebral heights in millimeters (marked in the black circle – the posterior, middle and anterior height, respectively, in order from the left) and the degree of deformation (%) of vertebral bodies (marked in the green circle – the wedge, biconcave and crush deformation, respectively, in order from the left). The red arrow indicates the position of the sacrum and the blue arrow the position of the L5 vertebra. Clear visualization of the sacrum and vertebra L5 is necessary for identification of examined vertebrae.
