Abstract
Background: Pelvic fractures account for 1–3% of all skeletal fractures and can be divided into high and low energy traumatic events. Classic techniques of internal fixation have traditionally required extensive surgical exposure of the deep structures of the pelvis, which can be associated with multiple complications which related to the surgical exposure itself, rather than to the initial injury. In an attempt to overcome the morbidity of extensile surgical approaches, percutaneous fixation of the pelvis has been receiving increasing attention The aim of the work: to evaluate the outcome of minimally invasive sacroiliac screw fixation for treatment of posterior pelvic instability, assess its accuracy, safety, effectiveness, and discuss potential pitfalls.. Materials and Methods: This work involved the study of a prospective case series. It included 18 patients admitted to Mansoura Emergency Hospital with posterior pelvic instability who were treated using minimally invasive fixation by iliosacral screw. Full history, examination and radiological assessment were done . follow up period was a 6 weeks ,12 weeks and 6 months , least period of follow up was 4,5 months . Assessment of outcome was clinically by Majeed score and radiologically by matta and Torneta method.
