It is a study evaluating the loss of bone mass and the degree of osteoporosis.
What is Osteoporosis?
Osteoporosis is the natural loss of naturally occurring bone substance with aging in both men and women, being markedly marked in women in the early postmenopausal years, resulting in weakening and "porosity in the bones."
The inner part of the bone is like a sponge, full of porosities (voids). The smaller the porosity, the greater the resistance of the bone. Osteoporosis produces a growth of these porosities, decreasing bone strength and increasing the risk of fractures, especially in the neck of the femur, spine and wrist.
