BACKGROUND: High-energy pelvic ring injuries (PRI) represent a heavy burden for institutions treating severely injured patients. Epidemiological data knowledge may help to provide them appropriate management. Only two epidemiologic studies about high-energy PRI were published during last decade. This study aimed to determine the gender-specific and global incidences of high-energy blunt AO/OTA type B or C PRI and their frequency among high-energy blunt trauma. It further reports the spectrum of these injuries and compares their characteristics and outcomes to high-energy blunt trauma without type B or C PRI.
HYPOTHESIS: Type B or C PRI incidence isn't gender specific and approximates 5/100,000/year.
PATIENTS AND METHODS: A prospective database of a level-I trauma center serving approximately 500,000 inhabitants was retrospectively queried for all high-energy trauma patients injured between 01.01.2014 and 12.31.2016. Inclusion criteria were: alive emergency department delivery; entire acute treatment at the authors' institution; age >16. Exclusion criteria were: penetrating, blast, burn and electrical injuries; drownings; low-energy trauma; patients living outside the institution's catchment area. Three authors performed PRI classifications. Clinical data were extracted from the database.
RESULTS: We analyzed 434 patients. High-energy blunt type B or C PRI incidence was 3.8/100,000/year without gender disparity (p=0.6697). High-energy blunt trauma incidence was lower in women than in men (20.5 vs. 51.6/100,000/year, p<0.001). Type B or C PRI frequency during high-energy blunt trauma was higher in women than in men (17.6% vs. 7.9%, p=0.003). Type B or C PRI patients were more severely injured and needed more treatment resources than other high-energy blunt trauma patients but didn't present higher complication or death rates.
DISCUSSION: The incidence of high-energy blunt type B or C PRI was comparable to previously published data. Women were less likely to sustain a high-energy blunt trauma, but when they sustained one, they were more likely to have a type B or C PRI. Despite higher injury severity score and resource requirements, complication and death rates weren't different between type B or C PRI patients and other high-energy blunt trauma patients.
LEVEL OF EVIDENCE: Level III, retrospective cohort study.
