## 4 Discussion
's study, where BMI was investigated in regard to pelvic fractures and their outcomes. They demonstrated that the highest number of APC type III injuries were found in the most obese patients [31]. Interestingly, these findings did not correlate to the lateral compression injuries in our study. In fact, we demonstrated that the LC II injury patients had a higher mean BMI than the LC III injury patients (25.4 vs. 23.9). Therefore, it is presented that only in an APC-type pelvic injury does an increasing BMI correlate with the severity of the trauma. Regarding the time of surgery, despite there being no statistically significant differences between Young and Burgess type and degrees of fractures, it should be noted that the LC II-type injury had the lowest mean time in surgery. The data from this study suggest that this was near the statistically significant cut-off (\(p\) = 0.0620). Thus, it should be noted that patients with APC III- and LC III-type fractures demand more time spent in the operation theater. At this point, it is essential to remember that our study and the studies presented above concern only traumatic pelvic injury, and male predominance seems to correlate only to high-energy trauma. In 2016, [PERSON] et al. presented a study on the analysis of pelvic ring fractures in a US population. The studied group comprised almost 15,000,000 cases registered between 1990 and 2007 [32]. Their results showed that almost 70% of the registered pelvic ring fractures concerned females [32]. This study included every type of pelvic ring fracture, including low-energy fractures that, in many cases, concern patients with osteoporosis [33; 34]. However, only 7.7% of patients in the studied population were diagnosed and treated with osteoporosis [32]. As [PERSON] et al. presented in their 2021 worldwide meta-analysis comprising 86 studies, the global female prevalence for osteoporosis is 23.1% [35]. Therefore, we suspect that many of the females who suffered from low-energy pelvic ring fractures had already been suffering from undiagnosed or untreated osteoporosis. Only about 10% of the studied cases involved any operative treatment [32]. Since the majority of high-energy pelvic fractures are treated operatively, we suspect that the vast majority of those fractures in the US population were low-energy fractures. Unfortunately, this study does not include the mechanism of injury; however, we strongly suspect that the leading cause was low-energy falls, since over 50% of all registered cases concerned patients older than 75 years [32]. A similar result to the current study was obtained by our research team with regard to the mechanism of injury and pelvic fracture. [PERSON] et al., in 2022, investigated pelvic fractures that were treated in their trauma center and also managed to present the mechanism of injury associated with a specific type of pelvic fracture. They presented that 43% of all pelvic ring fractures in the studied population occurred due to a fall from height, and this was found to be the leading cause of pelvic ring fractures [23]. In our study, we discovered that falls from heights were the second leading cause of pelvic ring fractures at 36%. The most common type of mechanism that resulted in pelvic ring injury was observed to be car accidents at 38.6%. Interestingly, [PERSON] et al. demonstrated that car accidents are responsible for only 13% [23]. [PERSON] et al. came to a similar conclusion concerning the frequency of the mechanism of injury. In total, 33.6% of the studied population that suffered a pelvic fracture sustained it due to a fall from height. Therefore, our leading cause of pelvic ring fractures appears to correlate with the recent literature. As stated initially in the discussion, our study proved that, within our studied group, patients with posttraumatic injuries received a greater amount of blood units and had longer hospital stays compared to the non-polytrauma patients.
