Risk factors for complications following pelvic ring and acetabular fractures: A retrospective analysis at an urban level 1 trauma center

Background: Pelvic ring and acetabular fractures are some of the most morbid in orthopedic trauma. They commonly require large exposures for fixation and are associated with significant morbidity and mortality. This study attempts to identify risk factors for complications following operative fixation of pelvic injuries. Methods: 126 patients treated for pelvic injuries were reviewed retrospectively. Demographics, procedure characteristics, and outcomes were recorded. Variables associated with complications were analyzed using logistic regression analysis. Results: Complications occurred in 12 patients. Higher BMI, longer length of stay, and ilioinguinal approach were significantly associated with increased infection risk. Co-morbid heart disease and concurrent smoking status showed a trend for increased infection risk. Higher BMI and ilioinguinal approach were significantly associated with an increased likelihood of re-operation. Positive psychiatric history and Medicaid payer status showed a trend toward higher reoperation risk. Conclusion: Knowledge of these risk factors can help guide management and predict outcomes following pelvic fracture fixation.
