The number of people above 60 years of age is predicted to grow from 901 million in 2015 to 1.4 billion in 2030, as per the United Nations. One of the most common effects of aging is the decrease in the bone mass, which causes diseases such as osteoporosis or vertebral column deformity. The latter mostly happens due to functional issues in the intervertebral discs, which allow the backbone to bend slightly and absorb shock. In the event of a deformity, the natural discs need to be replaced by artificial ones via surgery, thereby allowing people to regain some degree of forward and backward bending movement.
