The document discusses four common types of bone fractures:
1. Comminuted fractures involve multiple bone fragments and can be challenging to treat.
2. Spiral fractures result from twisting forces and may require surgery or months in a cast.
3. Greenstick fractures are most common in children and cause partial bone breaks like bending a green twig.
4. Proper diagnosis and immobilization are needed for fractures to heal completely.
