What is a mandibular fracture crushed into multiple fragments called?

  1. Greenstick

  2. Comminuted

  3. Compound

  4. Simple

The correct answer is: Comminuted

A mandibular fracture that is crushed into multiple fragments is called a comminuted fracture. This type of fracture occurs when the bone shatters into multiple pieces, which can make treatment and healing more challenging compared to other types of fractures such as greenstick, compound, or simple fractures. - A greenstick fracture is an incomplete fracture where the bone is bent and partially broken, more commonly seen in children due to their bones being more flexible. - A compound fracture is when the broken bone pierces through the skin, increasing the risk of infection. - A simple fracture, also known as a closed fracture, is when the bone breaks but does not pierce through the skin.
