The growing elderly population in the United States presents medical, engineering, and legislative challenges in trauma management and prevention. Thoracic injury incidence, morbidity, and mortality increase with age. This study utilized receiver-operator characteristic analysis to identify the quantitative age thresholds associated with increased mortality(More)
In military, automotive, and sporting safety, there is concern over eye protection and the effects of facial anthropometry differences on risk of eye injury. The objective of this study is to investigate differences in orbital geometry and analyze their effect on eye impact injury. Clinical measurements of the orbital aperture, brow protrusion angle, eye(More)
Motor vehicle accidents are the leading cause of death of people between one and thirty-four years of age in the U.S., and head trauma is a significant lethal injury in such cases. During a motor vehicle crash, the head often experiences blunt force trauma from impacts with seat backs, steering wheels, windows, and dashes. The resulting injuries can cause(More)
PURPOSE To measure eye and orbit anthropometric variation within the normal population by using CT images and to determine the effects of age and sex on eye and orbit anthropometry. Quantification of eye and orbit anthropometric variation within the normal population and between persons of different age and sex is important in the prediction and prevention(More)
The objective of this study was to investigate side airbag (SAB) deployment in near side crashes and compare injuries and contact points between occupants with and without SAB deployment. Using NASS 2000-2008 and selecting for near side cases, with PDOF ± 20 degrees from 90 or 270, for non-pregnant adult belted occupants, there were 20,253 (weighted) SAB(More)
Eye trauma is an increasing problem, especially in the military, due to blunt force trauma. One way to mitigate eye injury is to wear protective eye equipment. An essential part of creating protective eye equipment is prototype testing in controlled eye trauma simulations. In addition, the protective equipment must fit properly and thus incorporate(More)
This study investigates vehicle mismatch in severe side-impact motor vehicle collisions. Research conducted by the Insurance Institute for Highway Safety has determined that vehicle mismatch often leads to very severe injuries for occupants in the struck vehicle, because the larger striking vehicle does not engage the lower sill upon impact, resulting in(More)
Pediatric occupants are vulnerable in motor vehicle crashes (MVCs), and alternative restraints have been developed for their protection. This study sought to characterize injuries in MVCs for pediatric occupants and to identify scenarios that may benefit from enhanced vehicle safety. Using the NASS-CDS database (2000-2008), pediatric occupants (< 19 yr old)(More)
Injury statistics show that lower extremity injuries follow second to head trauma in motor vehicle crashes. Fractures to the ankle/foot make up approximately 35% of all lower extremity injuries in motor vehicle crashes. Previous studies have shown that toe pan intrusion is one of the main causes of foot and ankle fractures in motor vehicle crashes (MVC).(More)
In 2008, there were more than 5,000 motorcycle crash fatalities in the United States. Many states have motorcycle helmet laws that are meant to protect riders during a crash. After recruiting motorcycle occupants injured in crashes, a protocol was established to scan three different types of motorcycle helmets commonly worn (cap, ¾ shield, and full face(More)
