A buckle fracture of the cortex is also known as which type of fracture?

Explanation:
A buckle fracture of the cortex is called a torus fracture. In children, bones are more pliable, so bending forces compress the cortex on one side and cause it to buckle without a complete break through the bone. This creates an incomplete, stable fracture—the cortex tents or buckles rather than forming a full fracture line. On X-ray you’ll see a localized, smooth bulge of the cortex, commonly in the distal radius. This distinguishes it from a greenstick fracture, where the bone on the opposite side actually fractures while the other bends. Torus fractures are typically treated with immobilization and heal well as the child grows.
