old aged people. There are two types of osteoporosis. Such as
primary and secondary osteoporosis [2]. In primary osteoporosis,
postmenopausal and senile osteoporosis is included [3]. While
secondary osteoporosis leads to decrease of bone density and
also affects the process of bone growth [4]. Osteoporosis occurs
when the formation of new bone doesn’t maintain with loss of old

it is called as 'Silent disease'. In some cases, thoracic spine shows
