Bone Homeostasis

Remodeling is the process of creating new bone and removing old bone. It occurs constantly in growing children as well as in adults in the following situations:
  • When bones grow, remodeling causes bone tissue to be redistributed to maintain the shape and structure of the bone.
  • In response to new stresses applied to a bone, remodeling increases bone strength by adding new bone tissue where appropriate.
  • Remodeling enables calcium stored in the bones to be removed for metabolic processes in other parts of the body. Similarly, remodeling occurs when excess calcium is returned to the bone reservoir.
  • Remodeling occurs during the repair of broken bones.
