values at the hip, vertebral osteopenia – hip osteoporosis. Theoretically speaking, there<br />

is also the possibility of having normal values at the vertebral column and osteoporosis<br />

at the hip, but we haven’t encountered this situation in the set we analyzed.<br />

Fig. 4. The relation between the Z-score and age in the analyzed set:<br />

A, vertebral column; B, hip.<br />

The Z-score has an increase tendency with increasing age, both at the vertebral column and<br />

at the hip bone. This is related to the fact that the calculation of the Z-score takes into<br />

account the bone mineral density of a population of the same age.<br />

We noticed that the most numerous cases are those of vertebral osteoporosis<br />

and hip osteopenia (56.94%). They are followed by the cases of both vertebral<br />

osteoporosis and hip osteoporosis (29.17%), and then by those with normal values at<br />

the hip and vertebral osteoporosis. The least numerous cases are those of hip<br />

osteoporosis and vertebral osteopenia (4.44%) and those of vertebral osteoporosis, with<br />
