Detailed explanation-1: -The osteoid density of a child’s bone is less than an adult’s. Juvenile bone is more porous than adult bone because the Haversian canals occupy a much greater part of the bone (Figure 4). This is the principal reason a child’s bone can bend more than an adult’s bone.
Detailed explanation-2: -A child’s bones are more flexible because their chemical composition is different from that of adult bones. This means a kid’s bone might bend or “bow” instead of breaking.
Detailed explanation-3: -Children’s bones heal quicker than adult bones do because their bones are still growing. Their bones can remodel over a period of time. The process can take a few months to a few years. For most children, the process of remodeling will lead to complete bone healing.
Detailed explanation-4: -It’s all about the fact that the bones of a child contain far more periosteum, a dense layer of vascular connective tissue covering their bones. Not only does this make their bones thicker and stronger, but it also means recovery and healing time is much quicker.
