Aighty so I’m a swiss med-student and had some minutes to spare on the shitter. Here’s a picture of the possible fractures depending on the direction of the force of impact: https://i.imgur.com/pKqmk6o.jpg
After watching the video a few times I’d argue this be a anteroposterior compression (B). So if it’s B1 then only the ligament in the front is ruptured. With B3 the ligaments in the back of the picture (sacroiliac ligaments) would be ruptured too. Studies seem to suggest, that ruptures in that area (posterior pelvic ring) seem to correlate with a higher chance of complications:
“While Young and Burgess found a correlation between major ligamentous injury (lateral compression III, anteroposterior compression II/III) and an increased risk of hemorrhage [37], subsequent studies have failed to demonstrate a consistent correlation between injury type and mortality or the need for angiographic embolization [38-40]. However, the largest review, involving 1248 pelvic fractures, reported that patients with unstable fracture patterns (lateral compression II/III, anteroposterior compression II/III, vertical shear) required twice the transfusion rate of patients with stable injuries (4.9 versus 2.4 units) and sustained increased mortality (11.5 versus 7.9 percent) [40]. One prospective observational study found that sacroiliac joint disruption, regardless of the Young-Burgess classification, predicts the need for angiographic embolization (odds ratio [OR] 4.5; 95% CI 1.6-12.6) [27]. Overall, evidence suggests that patients who sustain a major injury to the posterior pelvic ring are more likely to have complications.” (Source: UpToDate)
