Why does a child's fracture heal more rapidly than the adults?

A. Children’s bones are actually more porous, not less, which contributes to their flexibility but not faster healing. B. Bone overgrowth is a normal response in children and is not a limiting factor in healing. C. Children’s bones have a thicker, more active periosteum, which is the outer membrane of bone involved in healing and bone formation. This enhanced periosteal activity helps in faster callus formation and bone repair. D. Children have faster, not slower, callus formation, contributing to their quicker healing times.
