A comminuted (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 break.
Someone with a comminuted fracture will probably need surgery. Then, he or she will need to wear a splint or cast for a while to keep the bone from moving while it heals.
