Which of the following types of fractures happens when a vertebra has been crushed in all directions?

A) Avulsion
B) Burst

D) Depressed

A burst fracture occurs when a vertebra is crushed in all directions, resulting in the collapse of the vertebral body. This type of fracture is often seen in high-energy trauma such as a car accident or fall from a height. A) Avulsion refers to a small piece of bone being pulled away from the main structure due to strong muscle or ligament attachment. C) Comminuted refers to a fracture where the bone is shattered into multiple pieces. D) Depressed refers to a fracture where a portion of the bone is pressed inward, typically seen in skull fractures.
