Associated peritoneostomy and pelvic ring fractures: prognostic factors in mortality and morbidity.

Background: High-energy polytrauma can be presented as an abdominal injury associated with a pelvic ring fracture. In the case of concomitant pelvic ring fracture peritoneostomy at admission, high morbidity and mortality rates could be expected.

Objectives: The main objective of this study is to assess prognostic factors that could contribute to the outcome of polytrauma patients who presented with pelvic ring fractures and were submitted to a peritoneostomy at admission.
