Final answer:
A comminuted fracture involves a bone that breaks and splinters into multiple pieces. Surgical intervention is often required to treat this type of fracture.
Step-by-step explanation:
The type of fracture that involves a bone that breaks and splinters is a comminuted fracture. In this type of fracture, the bone shatters into multiple pieces. This can happen due to high impact trauma, such as a car accident or a fall from a great height. Comminuted fractures require surgical intervention to realign and stabilize the bone fragments for proper healing.
