Nightstick fracture

Nightstick fractures are isolated fractures of the ulna, typically in the mid-diaphysis, usually resulting from a direct blow. It is a characteristic defensive fracture when the patient tries to ward off an overhead blow from an assailant.

Treatment and prognosis

Although typically a closed fracture, they have a higher rate of delayed union or non-union.

History and etymology

Historically this fracture was seen not infrequently due to a strike from a policeman’s baton (known as a nightstick in the USA).
