A total of 76 patients who underwent operative treatment for pelvic ring fractures between 2017 and 2022 met the inclusion criteria and were included in the study (Chart 1). The inclusion criteria required patients to have a pelvic fracture demanding surgery, either with or without concomitant injury. The studied cohort had a mean BMI of 26.4 (ranging from 17.8 to 44.8). The mean duration of surgery was 102.4 min, ranging from 35 to 270 min. The average number of blood transfusions received was 0.8 units, in a range of 0 to 5 units. The mean length of hospital stay was 4.9 days, ranging from 1 to 36 days. In total, 23 patients (%) were female and 53 patients (%) were male. Statistical analysis showed significant differences between male and female populations in terms of BMI (\(p\) = 0.01223), (Figure 1A) but none in duration of surgery (\(p\) = 0.8104), blood transfusion (\(p\) = 0.8066), and length of hospital stay (\(p\) = 0.5628) (Figure 1B-D). In the female subgroup, the mean BMI was 24.36 (ranging from 17.85 to 33.33), while in the male subgroup, it was 27.25 (ranging from 17.9 to 44.87). The average surgery duration for females was 95.91 min (ranging from 25 to 240 min), and for males, it was 105.1 min (ranging from 35 to 260 min). The mean length of hospital stay for females was 4.1 days (ranging from 2 to 23 days), whereas for males, it was 5.34 days (ranging from 1 to 36 days). Additionally, the mean amount of blood transfused for females was 0.73 units (ranging from 0 to 5 units), while for males, it was 0.88 units (ranging from 0 to 4 units). **Chart 1. ** A flow diagram of patients included in the study and interventions. **Figure 1.

When analyzing the population according to the Young and Burgees classification (Table 1), statistically significant differences were observed in BMI (\(p\) = 0.01) distribution among the subgroups with certain types of fracture (Figure 2A). Patients with a higher BMI had more frequent APC II and APC III fractures. On the other hand, there were no significant differences in the time of surgery (\(p\) = 0.06), length of hospital stay (\(p\) = 0.12), or blood transfusion (\(p\) = 0.75) within certain subgroups (Figure 2B-D). The [PERSON]'s rho correlation analysis between BMI and surgery duration (\(p\) = 0.44), blood transfusion (\(p\) = 0.84), and length of hospital stay (\(p\) = 0.12) did not reveal a statistically significant relationship (Figure 3A-C). \begin{table}
