Surgical treatment of pelvic fractures is an advanced intervention associated with multiple complications. The primary aim of this study was to investigate the rate of unplanned reoperations after pelvic fracture surgery. Secondary aims included occurrence of other adverse events and mortality.
All adult patients ≥ 18 years with surgically treated pelvic fracture operated at the Karolinska University Hospital in Sweden between 2010 and 2019 were identified and retrospectively included. Data were collected through review of medical records and radiographs. Logistic regression analysis was performed to evaluate factors associated with unplanned reoperations and other adverse events.
A total of 194 patients were included with mean age (± SD, range) 45.4 (16, 18–83) years. 62% were males (n = 121) and the median (IQR) follow-up time was 1890 (1791) days (4.9 years). Forty-eight patients (25%) had an unplanned reoperation, with infection being the most common cause of reoperation (n = 18, 9.3%). Seventy-eight (40%) patients had an adverse event not requiring reoperation and the most common event was nerve injury (n = 34, 18%). Concomitant abdominal injury was identified as a risk factor for an adverse event (OR 2.5, 95% CI 1.3–4.9, p < 0.01). 30-day mortality was 1.5% and 1-year mortality 6.2%.
The rate of unplanned reoperation after pelvic fracture surgery was high, as was the rate of other adverse events not requiring surgery. No identified risk factor was found to predict further surgery, but concomitant abdominal injury was a risk factor for other adverse events. Mortality was low at both 30 days and 1 year.
