A comminuted fracture is a bone break where the bone is smashed into several pieces.

In this illustration the fragments of the comminuted fracture are un-displaced. If the fragments are displaced, it is important to try to 'reduce' them and hold them in position while the fractures heal.

A comminuted fracture may occur in any bone, but in the knee one is usually referring to the patella (kneecap). Cerclage wires are often used to hold the fragments together until healing takes place.
