Why does prolonged immobilization after a bone fracture delay complete recovery more in adults compared to children?

💡 Explanation

In adults, bone remodeling depends heavily on mechanical loading to stimulate osteoblast activity. Immobilization reduces mechanotransduction, hindering bone remodeling and delaying recovery, because the piezoelectric signals are reduced. Therefore, remodeling is less efficient than in children, rather than increased osteoclast activity or cartilage content being the primary factor.
