Bone remodeling (or
bone metabolism) is a lifelong process where mature
bone tissue is removed from the
skeleton (a process called
bone resorption) and new bone tissue is formed (a process called
ossification or
new bone formation). These processes also control the reshaping or replacement of bone following injuries like
fractures but also
micro-damage, which occurs during normal activity. Remodeling responds also to functional demands of the mechanical loading.
