“…1,18 Although side airbags were not found to be protective for pelvic fractures in this study, their primary design is to protect the head and chest regions not the pelvis. 15 Our data may suggest a role for changes in side airbag design. If the increase in BMI may be protective against pelvic fractures, perhaps side airbag design could evolve to replicate the "protective fat" theory of larger BMI occupants.…”

“…In contrast, for normal BMI occupants, the center console was more likely to be the source of pelvic injury. Tencer et al 15 has shown the importance of center consoles causing pelvic fracture; however, there was no assessment of the influence of BMI in relation to these injuries. 14,15 Although the biomechanics causing pelvic fractures need further study, occupants who are overweight or obese may not be as likely to be displaced laterally compared with those with a lower BMI.…”

“…Furthermore, far-side occupants have almost the same risk for PMI on PMI 1+ and even higher risk for PMI on PMI10+ compared to near-side occupants among lower extremity injuries. The center console has previously been identified as a possible cause for pelvis, hip, and femur fractures for far-side occupants (Banglmaier et al 2003;Tencer et al 2007). It could be a contributing reason for the high risk for PMI among lower extremity injuries among side occupants.…”

Objective: There is limited knowledge of the long-term medical consequences for occupants injured in car crashes in various impact directions. Thus, the objective was to evaluate whether injuries leading to permanent medical impairment differ depending on impact direction.Methods: In total, 36,743 injured occupants in car crashes that occurred between 1995 and 2011 were included. All initial injuries (n = 61,440) were classified according to the Abbreviated Injury Scale (AIS) 2005. Injured car occupants were followed for at least 3 years to assess permanent medical impairment. The data were divided into different groups according to impact direction and levels of permanent impairment. The risk of permanent medical impairment was established for different body regions and injury severity levels, according to AIS.Results: It was found that almost 12% of all car occupants sustained a permanent medical impairment. Given an injury, car occupants involved in rollover crashes had the highest overall risk to sustain a permanent medical impairment. Half of the head injuries leading to long-term consequences occurred in frontal impacts. Far-side occupants had almost the same risk as near-side occupants. Occupants who sustained a permanent medical impairment from cervical spine injuries had similar risk in all impact directions (13%) except from rollover (17%). However, these injuries occurred more often in rear crashes. Most of the injuries leading to long-term consequences were classified as minor injuries by AIS for all impact directions.Conclusions: Studying crash data from a perspective of medical impairment is important to identify injuries that might not be prioritized only considering the AIS but might lead to lower quality of life for the occupant and also costs for society. These results can be used for road transport system strategies and for making priority decisions in vehicle design.

Motor vehicle collisions cause substantial mortality, morbidity, and expense worldwide. Certain types of injuries are more likely to result from frontal versus side-impact collisions, and knowledge of these specific patterns and why they occur aids in accurate and efficient diagnosis of traumatic injuries. Although the proper use of seat belts decreases crash-related mortality during frontal impact, certain injury patterns to the torso are directly attributed to restraint use. The spectrum of seat belt-related injuries ranges from mild skin and soft-tissue contusions to traumatic bowel injuries and unstable spine injuries that require surgery. Impact with the steering wheel or windshield during a frontal crash can cause characteristic injuries to the head, neck, torso, and distal upper extremity. Steering wheel deformity is an independent predictor of serious thoracic and abdominal injury among front-seat passengers. Impact of a flexed knee with the dashboard during a frontal collision can cause knee, thigh, and hip injuries. Distal lower extremity injuries are encountered frequently when the floorboard is driven into the foot. Lateral impact crashes often result in traumatic brain, thoracic, abdominal, and pelvic injuries, which are more often fatal to occupants on the side of the impact. The specific mechanism-based injury patterns are reviewed to establish a structured systematic search pattern that enables the radiologist to identify traumatic injuries with greater accuracy and speed, thereby improving the care of patients who experience acute trauma. ©

Reducing Primary and Secondary Impact Loads on the Pelvis during Side Impact

Abstract: Redesigning the center console using less stiff materials and allowing some lateral translation of the seat could aid in reducing pelvic injuries in side impact collisions.
