“…Anecdotally, these injuries are rarely contaminated with secondary blast fragments such as sand and grit, as the surrounding vehicle provides protection. There have been some efforts to replicate experimentally mounted injury patterns; however, they have not been based on robust clinical data sets, and do not necessarily represent realistic clinical end points17.…”

Environment at the time of injury determines injury patterns in pelvic blast

The use of explosives by terrorists, or during armed conflict, remains a major global threat. Increasingly, these events occur in the civilian domain, and can potentially lead to injury and loss of life, on a very large scale. The environment at the time of detonation is known to result in different injury patterns in casualties exposed to blast, which is highly relevant to injury mitigation analyses. We describe differences in pelvic injury patterns in relation to different environments, from casualties that presented to the deployed UK military hospitals in Iraq and Afghanistan. A casualty on foot when injured typically sustains an unstable pelvic fracture pattern, which is commonly the cause of death. These casualties die from blood loss, meaning treatment in these should focus on early pelvic haemorrhage control. In contrast, casualties injured in vehicle present a different pattern, possibly caused by direct loading via the seat, which does not result in pelvic instability. Fatalities in this cohort are from injuries to other body regions, in particular the head and the torso and who may require urgent neurosurgery or thoracotomy as life-saving interventions. A different strategy is therefore required for mounted and dismounted casualties in order to increase survivors.

“…Specimen positioning for all tests was described in a previous work [5] and can be summarized by a 90-90 deg knee-thigh-hip angle position with a pelvic plane (defined using the anterior supe rior iliac spines and the pubic symphysis) rotated -23 ± 5 deg about the SAE-y axis from the SAE-yz plane [18]. A preload of 22 ± 5 N measured using a Borroughs BT3329-S tension gage (Sealed Power Corporation, Kalamazoo, MI) was applied to the legs using a Velcro strap adjusted across the knees of the speci men, which released after floor pan impact.…”

Response of the human body to high-rate vertical loading, such as military vehicle underbody blast (UBB), is not well understood because of the chaotic nature of such events. The purpose of this research was to compare the response of postmortem human surrogates (PMHS) and the Hybrid-III anthropomorphic test device (ATD) to simulated UBB loading ranging from 100 to 860 g seat and floor acceleration. Data from 13 whole body PMHS tests were used to create response corridors for vertical loading conditions for the pelvis, T1, head, femur, and tibia; these responses were compared to Hybrid-III responses under matched loading conditions.
