A comminuted (pronounced: kah-muh-NOOT-ed) fracture is a type of broken bone. The bone is broken into more than two pieces.
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 fracture.
Someone who gets a comminuted fracture probably will need surgery. After surgery, the person will wear a splint or cast for a while to keep the bone from moving while it heals.
