Fat embolism syndrome: history, definition, epidemiology

The first clinical case of fat embolism was described over 100 years ago and significant progress has been made in the understanding of this condition since then. Gurd's criteria, consisting of major and minor clinical features, is the most commonly used diagnostic tool in the literature. Due to the lack of a gold standard for diagnosis, clinical criteria cannot be validated. It is now recognized that although fat embolization occurs in the majority of patients with long bone fractures, clinical signs and symptoms occur only in 1-10% of patients with fractures.
