Purpose: Open pelvic bone fractures are relatively rare and are considered more severe than closed fractures. This study aimed to compare the clinical outcomes of open and closed severe pelvic bone fractures. Methods: Patients with severe pelvic bone fractures (pelvic Abbreviated Injury Scale score, ≥4) admitted at a single level I trauma center between 2016 and 2020 were retrospectively analyzed. Patients aged <16 years and those with incomplete medical records were excluded from the study. The patients were divided into open and closed fracture groups, and their demographics, treatment, and clinical outcomes were compared before and after 1:2 propensity score matching. Results: Of the 321 patients, 24 were in the open fracture group and 297 were in the closed fracture group. The open fracture group had more infections (37.5% vs. 5.7%, P<0.001) and longer stays in the intensive care unit (median 11 days, interquartile range [IQR] 6-30 days vs. median 5 days, IQR 2-13 days; P=0.005), but mortality did not show a statistically significant difference (20.8% vs. 15.5%, P=0.559) before matching. After 1:2 propensity score matching, the infection rate was significantly higher in the open fracture group (37.5% vs. 6.3%, P=0.002), whereas the length of intensive care unit stay (median 11 days, IQR 6-30 days vs. median 8 days, IQR 4-19 days; P=0.312) and mortality (20.8% vs. 27.1%, P=0.564) were not significantly different. Conclusions: The open pelvic fracture group had more infections than the closed pelvic fracture group, but mortality was not significantly different. Aggressive treatment of pelvic bone fractures is important regardless of the fracture type, and efforts to reduce infection are important in open pelvic bone fractures.

Pelvic bone fracture with unstable vital signs is a life-threatening condition demanding proper diagnosis and immediate treatment. Unlike long bones, the pelvic bone is a three dimensional structure with complex holes and grooves for vessels and nerves. Because of this complexity, a pelvic bone fracture can lead to complicated and serious bleeding. We report a case of a fifty-year-old male suffering from a pelvic bone fracture due to a fall. An imaging study showed fractures of both the superior and the inferior ramus of the pubic bone, with contrast extravasation underneath them, resulting in a large preperitoneal hematoma. He was sent for angiography, which revealed a hemorrhage from a branch of the left obturator artery. Embolization was done with a glue and lipiodol mixture. The patient recovered without complication, and was discharged at four weeks after admission.

Purpose: Hemorrhagic shock is the leading cause of death in patients with pelvic bone fractures. The majority of blood loss is due to injured pelvic arteries and retroperitoneal veins and to bleeding from the fracture site itself. Pelvic angiography and embolization of injured vessels is an effective way to control continuous bleeding. However, identifying the bleeding focus in hemodynamically unstable patients before diagnostic intervention is difficult. The purpose of this study was to determine the correlation between fracture patterns in hemodynamically unstable patients with pelvic fractures and later pelvic angiography findings. Methods: We performed a retrospective study of 21 hemodynamically unstable patients with pelvic fractures admitted to our emergency department between April 2001 to April 2006. All 21 patients underwent pelvic angiography. Pelvic fractures were assessed according to the Tile's classification and the degree of injury was assessed using the Injury Severity Score (ISS) and Revised Trauma Score (RTS). The hemodynamic status of the patients was defined using vital signs, base excess, and blood lactate. Fracture patterns were compared with hemodynamic status and angiography findings. Results: In the 5year study period, 21 hemodynamically unstable pelvic bone fracture patients were admitted; ten were men (47.6%), and 11 were women (52.4%). The mean age was 41.1 years (range: ${\pm}20.1$). Of the 21 embolization was performed in 6 patient (28.6%): 1 patient of the 5 unstable pelvic bone fracture patients (20%), and 5 patients of 16 the stable pelvic bone fracture patients (31.3%). There were no significant differences between the RTS (p=0.587) and embolization rate (p=0.774) for either the stable patients or the unstable patients. Patients with arterial injury on angiography had a lower RTS compared with patients without arterial injury but there was no significant difference in ISS between the two groups. The angiographic injured sites were five internal femoral arteries and one external femoral artery. Conclusion: The findings in this study suggest that the pelvic fracture pattern in hemodynamically unstable patients with pelvic fractures does not correlate with pelvic angiography findings.

Pelvic bone fracture with hemodynamic instability is fatal and the mortality rate can range up to 40%. Despite the big advances in the treatment of massive bleeding and hemorrhagic shock, the mortality associated with hemodynamically unstable pelvic bone fractures remains high. The gold standard of treatment for pelvic bone fracture with hemodynamic instability has not yet been determined and is an issue of main discussion among many doctors. Retroperitoneal packing is not yet wide spread in Korea, but is a good modality for managing of massive bleeding from pelvic bone fractures when an angiography suite or an expert surgeon is not available. A vacuum-assisted closure (VAC) system can also be applied with retroperitoneal packing in the manner of damage control surgery and open abdomen surgery. We present the case of a 51-year-old male who had a pelvic bone fracture with massive bleeding. We performed retroperitoneal gauze packing with a VAC system for the first time. The postoperative vital signs of patient were immediately stable, the massive bleeding was easily and quickly controlled, and the amount of transfusion of blood components was reduced.

Purpose: This research was conducted to study whether the specific location of pelvic-bone fractures could increase the risk for injury to the urinary bladder, urethra, or lower gastrointestinal tract. Methods: We retrospectively reviewed the data of 234 patients with pelvic-bone fractures who visited the emergency department of Kyungpook National University Hospital from January 2004 to December 2006. The location of the pelvic-bone fracture was divided into 8 parts. The association of fracture location with injury to the urinary bladder, urethra, or lower gastrointestinal tract was analyzed with Fisher' s-exact test and multiple logistic regression. Results: Nineteen(19) patients had urinary bladder injury, 8 had urethral injury, and 9 had lower gastrointestinal tract injury. The following fracture locations were found to be significant; urinary bladder: sacroiliac (SI) joint (p<0.001), symphysis pubis (p=0.011), and sacrum (p=0.005); urethra: SI joint (p=0.020); lower gastrointestinal tract: symphysis pubis (p=0.028). After the multiple logistic regression analysis, the primary and the independent predictors for each of the injuries were as follows; urinary bladder: sacroiliac joint (p=0.000, odds ratio [OR]=10.469); lower gastrointestinal tract: symphysis pubis (p=0.037, OR=7.009). Conclusion: Consideration of further workup for injuries to the lower gastrointestinal and urinary tract is needed for some locations of pelvic-bone fractures because certain pelvic-bone fracture locations, especially the sacroiliac joint and the symphysis pubis, are associated with increased risk for injury to the lower gastrointestinal and urinary tracts.

Purpose: Damage control laparotomy has contributed to improved survival rates for severe abdominal injuries. A large part of severe abdominal injury occurs with a concomitant pelvic bone fracture. The safety and effectiveness of internal fixation of pelvic bone fracture(s) has not been established. The aim of the present study was to evaluate infection risk in the pelvic surgical site in patients who underwent emergent abdominal surgery. Methods: This single-center retrospective observational study was based on data collected from a prospectively maintained registry between January 2015 and June 2019. Patients who underwent laparotomy and pelvic internal fixation were included. Individuals <18 and ≥80 years of age, those with no microbiological investigations, and those who underwent one-stage abdominal surgery were excluded. Comprehensive statistical comparative analysis was not performed due to the small number of enrolled patients. Results: A total of six patients met the inclusion criteria, and the most common injury mechanism was anterior-posterior compression (67%). The average duration of open abdomen was 98 hours (range, 44-98), and the time interval between abdominal closure and pelvic surgery was 98 hours. One patient (16.7%) died due to multi-organ dysfunction syndrome. Micro-organisms were identified in the abdominal surgical site in five patients (83%), with no micro-organisms in pelvic surgical sites. There was no unplanned implant removal. Conclusions: Internal fixation of pelvic bone fracture(s) could be performed in the state of open abdomen, and the advantages of early fixation may countervail the risks for cross contamination.

Purpose: Immediate identification of vascular injury requiring embolization in patients with pelvic bone fracture isn't an easy task. There have been many trials finding indicators of embolization for patients with pelvic bone fracture. Although Young and Burgess classification is useful in decision making of treatment, it is reported to have little value as indicator of embolization in major trauma patients. The aim of this study is to find out Young and burgess classification on predicting vessel injury by analzyng pelvic radiograph taken from major trauma patients with pelvic bone fracture. Methods: Among major trauma patients with injury severity scores (ISS) higher than 15 who visited our emergency room from January 2011 to June 2014, 200 patients were found with pelvic bone fracture in trauma series and thus pelvic CT angiography was taken. Setting aside patients with exclusion criteria, 153 patients were enrolled in this study for analysis of Young and Burgess classification. Results: The most common mechanism of injury was lateral compression in both groups. There was no statistical significant difference in Young and Burgess classification (p=0.397). The obturator artery was the most commonly injured artery in both groups. Six patients had more than one site of bleeding. Conclusion: Prediction of transcatheter angiographic embolization using Young and Burgess classification in severe trauma patients is difficult and requires additional studies.

Purpose: Hypovolemic shock is the leading cause of death in multiple trauma patients with pelvic bone fracures. The purpose of this study was to develop a simple prediction method for injury severity and amount of hemorrhage via an analysis of the correlation between the site of pelvic bone fracture and the amount of transfusion and to verify the usefulness of the such a simple scoring system. Methods: We analyzed retrospectively the medical records and radiologic examination of 102 patients who had been diagnosed as having a pelvic bone fracture and who had visited the Emergency Department between January 2007 and December 2011. Fracture sites in the pelvis were confirmed and re-classified anatomically as pubis, ilium or sacrum. A multiple linear regression analysis was performed on the amount of transfusion, and a simplified scoring system was developed. The predictive value of the amount of transfusion for the scoring system as verified by using the receiver operating characteristics (ROC). The area under the curve of the ROC was compared with the injury severity score (ISS). Results: From among the 102 patients, 97 patients (M:F=68:29, mean $age=46.7{\pm}16.6years$) were enrolled for analysis. The average ISS of the patients was $16.2{\pm}7.9$, and the average amount of packed RBC transfusion for 24 hr was $3.9{\pm}4.6units$. The regression equation resulting from the multiple linear regression analysis was 'packed RBC units=1.40${\times}$(sacrum fracture)+1.72${\times}$(pubis fracture)+1.67${\times}$(ilium fracture)+0.36' and was found to be suitable (p=0.005). We simplified the regression equation to 'Pelvic Bleeding Score=sacrum+pubis+ilium.' Each fractured site was scored as 0(no fracture) point, 1(right or left) point, or 2(both) points. Sacrum had only 0 or 1 point. The score ranged from 0 to 5. The area under the curve (AUC) of the ROC was 0.718 (95% CI: 0.588-0.848, p=0.009). For an upper Pelvis Bleeding Score of 3 points, the sensitivity of the prediction for a massive transfusion was 71.4%, and the specificity was 69.9%. Conclusion: We developed a simplified scoring system for the anatomical fracture sites in the pelvis to predict the requirement for a transfusion (Pelvis Bleeding Score (PBS)). The PBS, compared with the ISS, is considered a useful predictor of the need for a transfusion during initial management.

We report a case of early stress fracture of the pelvic ring following an extension of a multilevel instrumented lumbosacral fusion in an osteopenic female. Surgeons should be aware of possibilities of pelvic complications in osteopenic patients with lumbosacral arthrodesis and should take care when harvesting iliac bone graft.
