Which statement best defines a greenstick fracture?

• A. A complete break through the bone
• B. A fracture where the bone bends and cracks but does not break completely
• C. A fracture where the bone protrudes through the skin
• D. A fracture resulting in multiple fragments

Answer: (B)

A greenstick fracture is when the bone bends and cracks on one side but does not break all the way through. This partial fracture happens because bones in children are more flexible, so under force they tend to bend and crack rather than snap completely. It looks as if you tried to break a green twig—the outer layer splits while the inside stays connected. This differs from a complete fracture, where the bone splits into two or more pieces; from an open fracture, where the bone breaks the skin; and from a comminuted fracture, where the bone is broken into several fragments. Treatment focuses on immobilizing the limb with a cast or splint and ensuring proper follow-up to monitor healing and check blood flow and nerve function.
