The caudal/mobile segment of transverse fracturepatterns typically depends on symphyseal mobility (and other factors)in order to displace...in this patient, the clinical situation is furthercomplicated by the contralateral comminuted and displaced ramus fractures(an additional "hinge" for the mobile caudal segment) , as wellas the displacement of the cephalad segment (which is typically nondisplacedand stable, but for this patient is displaced and has potential rotary instability).
