What is the term for an injured bone that is partially broken?

The term for an injured bone that is partially broken is known as a greenstick fracture. This type of fracture commonly occurs in children because their bones are still flexible and not fully hardened. In a greenstick fracture, the bone bends and cracks on one side without breaking all the way through, resembling how a green twig might break partially while still remaining intact on the other side. This partial break is distinct from other fracture types, as it highlights the unique characteristics of immature bone structure in younger individuals.
