title: An unusual type of fracture in the upper sacrum.
abstract: An unusual type of indirect isolated fracture of the upper sacrum is presented. The upper sacrum was markedly comminuted and nondisplaced relative to the lower fragment. There was a neurologic deficit present. On the basis of a review of the literature, a previous classification system and the actual fracture mechanism, this fracture is classified as a special type; type 4, or the neutral position fracture.
