Bilateral femoral neck fractures associated with complex pelvic ring injuries in a pediatric patient: a case report.

J Pediatr Orthop B 2017 Jul;26(4):350-357

Department of Orthopaedic Surgery, University of South Alabama, Mobile, Alabama, USA.

Femoral neck and pelvic fractures are rarely encountered in the pediatric population secondary to the resilient nature of the immature skeleton. Both fracture types usually result from high-energy blunt trauma including motor vehicle collisions, motor vehicle-pedestrian accidents, and falls from height. Considerable studies have been published on the natural history, management, and complications of pediatric pelvis and femoral neck fractures. Read More

The influence of vehicle front-end design on pedestrian ground impact.

Accid Anal Prev 2015 Jun 24;79:56-69. Epub 2015 Mar 24.

Department of Mechanical and Manufacturing Engineering, Parsons Building, Trinity College Dublin, College Green, Dublin 2, Ireland.

Accident data have shown that in pedestrian accidents with high-fronted vehicles (SUVs and vans) the risk of pedestrian head injuries from the contact with the ground is higher than with low-fronted vehicles (passenger cars). However, the reasons for this remain poorly understood. This paper addresses this question using multibody modelling to investigate the influence of vehicle front height and shape in pedestrian accidents on the mechanism of impact with the ground and on head ground impact speed.

Pedestrian crossing situations: quantification of comfort boundaries to guide intervention timing.

Accid Anal Prev 2014 Oct 20;71:261-6. Epub 2014 Jun 20.

Autoliv Development AB, Autoliv Research, Wallentinsvägen 22, SE-44783 Vårgårda, Sweden.

Introduction: Technical systems that warn or brake for vehicle-pedestrian encounters reduce injuries more effectively the earlier an intervention is initiated. However, premature intervention can irritate drivers, leading to system deactivation and, consequently, no injury reduction whatsoever. It has been proposed that no intervention should be initiated as long as attentive drivers are within their comfort zones. Read More

The link between built environment, pedestrian activity and pedestrian-vehicle collision occurrence at signalized intersections.

Accid Anal Prev 2011 Sep 22;43(5):1624-34. Epub 2011 Apr 22.

Department of Civil Engineering and Applied Mechanics, McGill University, Canada.

This paper studies the influence of built environment (BE) - including land use types, road network connectivity, transit supply and demographic characteristics - on pedestrian activity and pedestrian-vehicle collision occurrence. For this purpose, a two-equation modeling framework is proposed to investigate the effect of built environment on both pedestrian activity and vehicle-pedestrian collision frequency at signalized intersections. Using accident data of ambulance services in the City of Montreal, the applicability of our framework is illustrated. Read More

A risk-based method for modeling traffic fatalities.

Risk Anal 2007 Feb;27(1):125-36

Harvard Initiative for Global Health, Harvard University, Cambridge, MA 02138, USA.

We describe a risk-based analytical framework for estimating traffic fatalities that combines the probability of a crash and the probability of fatality in the event of a crash. As an illustrative application, we use the methodology to explore the role of vehicle mix and vehicle prevalence on long-run fatality trends for a range of transportation growth scenarios that may be relevant to developing societies. We assume crash rates between different road users are proportional to their roadway use and estimate case fatality ratios (CFRs) for the different vehicle-vehicle and vehicle-pedestrian combinations.

Injury 2006 May 14;37(5):416-22. Epub 2006 Feb 14.

Department of Social Medicine, School of Public Health, Tongji Medical College, Wuhan, China.

Objectives: To examine motor vehicle-pedestrian collision injuries resulting in hospitalisation among children admitted into Wuhan Children's Hospital, The People's Republic of China.

Methods: From the 1993 to 2004 inpatient data of Wuhan Children's Hospital, we identified injury cases from motor vehicle traffic crashes among children aged 18 years or less using the discharge diagnosis defined by the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM). We examined characteristics of injuries from motor vehicle traffic crashes (ICD-9-CM = E810-E819) and then calculated the proportion of injuries from motor vehicle-pedestrian collisions (ICD-9-CM = E814) among all hospitalisations for childhood injuries (ICD-9-CM = 800-959).

Honda R&D Co, Ltd, Tochigi R&D Center, Tochigi, Japan.

For the evaluation of pedestrian protection, the European Enhanced Vehicle-Safety Committee Working Group 17 report is now commonly used. In the evaluation of head injuries, the report takes into account only the hood area of the vehicle. But recent pedestrian accident data has shown the injury source for head injury changing to the windshield and A-pillar from the hood. Read More

Comparative analysis of vehicle-bicyclist and vehicle-pedestrian accidents in Japan.

Accid Anal Prev 2003 Nov;35(6):927-40

Nissan Motor Company Ltd., 1, Natsushima-cho, Yokosuka-shi, Kanagawa 237-8523, Japan.

Bicyclist and pedestrian injuries in collisions with vehicles in Japan were investigated based on national and in-depth accident data analyses and mathematical simulations. In an impact with a bonnet-type vehicle, a bicyclist slides over the bonnet of the vehicle, behavior that is not observed for pedestrians. As a result, the bicyclist's head tends to strike a bonnet-type vehicle at a more rearward location in comparison with pedestrians. Read More

Mobilizing for pedestrian safety: an experiment in community action.

Inj Prev 2002 Dec;8(4):264-7

Department of Pediatrics, Harborview Medical Center (MS 359774), 325 9th Avenue, Seattle, WA 98104, USA.

In contrast to the steady reduction in mortality and morbidity from collisions involving motor vehicle occupants, relatively little progress has been made in controlling motor vehicle/pedestrian collisions. Engineering modifications are the most effective means of reducing such collisions, but mainly because of their cost, and public apathy about pedestrian safety, are too rarely employed. A modest experiment in community action was undertaken by attempting to induce the authorities of 10 small cities to apply for state funds to create a single model pedestrian refuge in their respective communities.

Fractures of the femoral shaft in children. Incidence, mechanisms, and sociodemographic risk factors.

J Bone Joint Surg Am 1999 Apr;81(4):500-9

The Johns Hopkins School of Hygiene and Public Health, Baltimore, Maryland 21205, USA.

Background: Fractures of the femoral shaft in children are caused by major musculoskeletal trauma and result in high direct and indirect medical costs. To date, the American literature has focused on treatment options and outcomes, but the epidemiology of these injuries has been generalized from Scandinavian studies reported in the 1970s and early 1980s. The goals of the current study were (1) to determine the age, gender, and race-specific rates and mechanisms of fractures of the femoral shaft in children in a large United-States-based population and (2) to identify associations between the rates of these fractures and multiple sociodemographic indicators.
