Lunate bone Lunate bone The lunate bone (semilunar bone) is a carpal bone in the human hand. It is distinguished by its deep concavity and crescentic outline. It is situated in the center of the proximal row carpal bones, which lie between the ulna and radius and the hand. The lunate carpal bone is situated between the lateral scaphoid bone and medial triquetral bone. The lunate is a crescent-shaped carpal bone found within the hand. The lunate is found within the proximal row of carpal bones. Proximally, it abuts the radius. Laterally, it articulates with the scaphoid, medially with the triquetral, and
Child bone fracture 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
