    Abstract:
    BACKGROUND: Pelvic fractures resulting from high-energy trauma can frequently present with life-threatening hemodynamic instability that is associated with high mortality rates. The role of pelvic exsanguination in causing hemorrhagic shock is unclear, as associated injuries frequently accompany pelvic fractures. This study aims to compare the incidence of hemorrhagic shock and in-hospital outcomes in patients with isolated and non-isolated pelvic fractures. METHODS: Registries-based study of trauma patients hospitalized following pelvic fractures. Data from 1997 to 2021 were cross-referenced between the Israel Defense Forces Trauma Registry (IDF-TR), documenting prehospital care, and Israel National Trauma Registry (INTR) recording hospitalization data. Patients with isolated pelvic fractures were defined as having an Abbreviated Injury Scale (AIS) <3 in other anatomical regions, and compared with patients sustaining pelvic fracture and at least one associated injury (AIS ≥ 3). Signs of profound shock upon emergency department (ED) arrival were defined as either a systolic blood pressure <90 mmHg and/or a heart rate >130 beats per min. RESULTS: Overall, 244 hospitalized trauma patients with pelvic fractures were included, most of whom were males (84.4%) with a median age of 21 years. The most common injury mechanisms were motor vehicle collisions (64.8%), falls from height (13.1%) and gunshot wounds (11.5%). Of these, 68 (27.9%) patients sustained isolated pelvic fractures. In patients with non-isolated fractures, the most common regions with a severe associated injury were the thorax and abdomen. Signs of shock were recorded for 50 (20.5%) patients upon ED arrival, but only four of these had isolated pelvic fractures. In-hospital mortality occurred among 18 (7.4%) patients, all with non-isolated fractures. CONCLUSION: In young patients with pelvic fractures, severe associated injuries were common, but isolated pelvic fractures rarely presented with profound shock upon arrival. Prehospital management protocols for pelvic fractures should prioritize prompt evacuation and resuscitative measures aimed at addressing associated injuries.
