Flashcard 8: _____ is pathognomonic for associated both-column fractures of the acetabulum.

Answer: Spur sign

Extra: The spur sign is seen on the obturator oblique view and represents the intact posterior part of the ilium. It is pathognomonic for associated both-column fractures because it indicates that the entire articular surface (both columns) has been separated from the axial skeleton ("floating acetabulum"). In transverse or T-shaped fractures, a portion of the acetabular roof remains attached to the ilium, so no spur is formed.
