• compound fracture

• greenstick fracture

• spiral fracture

Answer explanation

A greenstick fracture occurs when a bone bends and cracks, instead of breaking completely into separate pieces. The fracture looks similar to what happens when you try to break a small, "green" branch on a tree. Most greenstick fractures occur in children younger than 10 years of age.
