Classifications

The Tile and Pennal classification

Pennal et al [ 1] developed a classification from the mechanism of injury in which the direction of force that causes pelvic fractures are described as anteroposterior compression injuries, lateral compression injuries, or vertical shear injuries. Tile and Pennal [ 2] modified the Pennal system to make it an alphanumeric system involving three groups based on the concept of stability of the pelvic ring: A, stable; B, rotationally unstable but vertically stable; and C, rotationally and vertically unstable. This classification is widely used in the current literature [1, 2].
