What is four different kinds of fracture?

1. Complete fracture:

This is the most common type of fracture, in which the bone is completely broken into two or more pieces. Complete fractures can be displaced or non-displaced. Displaced fractures are those in which the bone fragments have moved out of place, while non-displaced fractures are those in which the bone fragments remain in their normal position.

2. Incomplete fracture:

This is a fracture in which the bone is not completely broken, but is instead cracked or splintered. Incomplete fractures are also known as greenstick fractures, as they often occur in children whose bones are still growing.

3. Avulsion fracture:

This is a fracture in which a piece of bone is pulled away from the main bone by a tendon or ligament. Avulsion fractures often occur during sports injuries or other accidents that involve sudden, forceful muscle contractions.

4. Compression fracture:

This is a fracture that occurs when a bone is crushed or compressed, often as a result of a traumatic injury or osteoporosis. Compression fractures are common in the spine, but can also occur in other bones.
