Pelvic bone fractures are usually caused by high-energy trauma and are often accompanied by organ injuries. For hemodynamically unstable patients with pelvic bone fractures, knowing the anatomic type of fracture-whether it is a pelvic ring injury or an acetabular fracture-might be helpful in prioritizing treatment. A total of 302 patients with pelvic bone fractures who received treatment at the authors' level I trauma center between March 1, 2015, and February 28, 2017, were included in this study. Patients with pelvic bone fractures were enrolled in the Korea Trauma Data Bank and classified by anatomic type of pelvic bone fracture: Pelvic ring injury, acetabular fracture, or combined fractures. The authors used t tests to analyze survival and death groups and multivariate regression to analyze mortality factors. Different types of pelvic bone fractures had significantly different mortality rates (P<.001). Forty-four (22.6%) of 195 patients with pelvic ring injuries and 6 (18.8%) of 32 patients with combined fractures died. Meanwhile, only 1 of 75 patients with isolated acetabular fractures died (1.3%). The mortality rate was lowest for type A pelvic ring injuries (8.2%) and highest for type C pelvic ring injuries (68.2%). The difference was statistically significant (P<.001). It is commonly acknowledged that age, combined injuries, higher Injury Severity Score, and lower initial systolic blood pressure are risk factors for mortality, but research has shown that classification and anatomic type of pelvic bone fracture are also highly related.
