Comminuted Fracture
Overview
What Is a Comminuted Fracture?
A comminuted (kah-muh-NOOT-ed) fracture is a type of broken bone. The bone is broken into more than two pieces.
How Do Comminuted Fractures Happen?
It takes a lot of force for someone to get a comminuted fracture. A car accident or serious fall, for instance, can cause this type of break.

Top Things to Know

- The injured area may be very painful, swollen, bruised, or appear crooked.
- Treatment often includes surgery followed by a cast or splint to protect the bone as it heals.
- The fracture is often caused by a high-impact event, like a car crash or major fall.
