What is fat embolism?

Particle that moves: The term embolism implies something "breaking off" or travelling from an area where it is typically found to another area, through the body, usually in the vascular system. Obviously fat implies some type of lipid particle. This type of embolism is usually related to a traumatic injury, often a bone fracture, allowing this material access to the vascular system. It can be very serious, even fatal.
