title: Acute fracture of the os trigonum.
abstract: A 21-year-old man presented with ankle pain after a motor vehicle accident. Imaging revealed an acute fracture of the os trigonum in addition to multiple, other lower-extremity fractures. In this case, the fracture of the os trigonum was a result of a significant traumatic injury. Thus, the presence of this fracture in an acute setting should prompt a search for other associated fractures.
