The increased use of fluoroscopy was not correlated with patient characteristics; resident year of training and fracture complexity demonstrated statistically significant associations with increasing fluoroscopic image acquisition, according to study results.

Researchers conducted a retrospective review of the electronic medical records for 100 patients who underwent primary open reduction and internal fixation (ORIF) for ankle fracture. Collected data included age, sex, BMI, resident year of training, total amount of images taken, imaging time in seconds and cumulative dose.

Findings showed as BMI increased, the number of images, total time and cumulative dose also increased; however, a bivariate analysis revealed this finding was not significant. The investigators found increased image acquisition significantly correlated with resident year of training and total image time. However, this relationship did not hold true for cumulative dose.

“After multiple regression analysis, fracture complexity and year of training remained clinical significant and were independent predictors of increased image acquisition,” the researchers wrote.

According to results of a multivariate analysis, resident year also was a predictor for an increase in image acquisition with six additional images each year and cumulative dose increased to 0.35 mGY. A clinically significant association was seen between image acquisition and resident year of training when Weber B fractures were isolated to lateral malleolus fracture fixation, according to researchers. by Monica Jaramillo
