Bone tissue is a very dynamic tissue, continuously remodelling itself through bone formation (by osteoblastic cells) and bone resorption (osteoclasts). During growth, bone accretion is higher than bone resorption, allowing the bone mass to increase. Between the ages of twenty and twenty-fi ve, this process is completed and a person’s ‘peak bone mass’ is normally reached. Peak bone mass is the maximum bone mass achieved in life. After this, for a certain period of time (30 to 50 years) there is a balance between the formation and degradation of bone tissue. In later life, the occurrence of bone resorption becomes higher than bone formation.
