Child bone fracture is a medical condition in which a bone of a child (a person younger than the age of 18) is cracked or broken. About 15% of all injuries in children are fracture injuries. Bone fractures in children are different from adult bone fractures because a child’s bones are still growing. There are differences in the bone structure of a child and an adult. These differences are important for the correct evaluation and treatment of the fractures. A child’s bones heal faster than an adult’s because a thicker, stronger, and more active dense fibrous membrane (periosteum) covers the surface of their bones. The periosteum has blood vessels that supply oxygen and nutrition to the bone cells. The stronger and thicker periosteum in children causes a better supply of oxygen and nutrients to the bones, and this helps in the remodeling of the fractured bones by supplying. The periosteum in children causes a more rapid union of fractured bones and an increased potential for remodeling. A child’s fractures not only heal more quickly, but are significantly reduced due to the thickness and strength of a child’s periosteum. But this thickness also has its drawbacks; when there is a small displacement in the periosteum the thickness and strength of it will make the fracture in the periosteum difficult to diagnose.
