title: Spinal cord injuries sustained in road crashes are not on the decrease in france: a study based on epidemiological trends.
abstract: Traumatic spinal cord injuries (SCI) are rare but extremely costly. In order to improve the modelling of inclusion criteria for studies of SCI it is necessary to determine what epidemiological trends affect SCI. Using the Rhone Registry, which contains all the casualties resulting from road crashes in the Rhône département of France and codes their injuries using the Abbreviated Injury Scale (AIS), we describe the epidemiological trends that affect spinal cord injury (SCI), major spinal trauma (MST) and severe injuries (AIS4+) to other body regions between two periods 1996-2001 and 2003-2008. Although there has been a marked decrease (35%) in the incidence of casualties after a road traffic crash, and reductions of 22% in the incidence of MST and 33% in that of severe injuries (AIS4+) (p<0.001), for SCI the incidence rate and number of casualties have remained surprisingly stable. In the second period, there was no change in the incidence of SCI resulting from road traffic crashes, nor in the associated fatality, mortality and survival rates. The incidence for car users was significantly lower in the second period. This contrasts with the incidences for motorcyclists and for the group including pedestrians and cyclists which were respectively 47% and 77% higher in the second period. The median age of the casualties, the age-adjusted incidence of SCI and the number of associated injuries were also higher in the second period. We have observed a marked reduction in the incidence of road trauma including the most severe injuries, but not SCI. The higher proportion of motorcyclists, the increase in the age of casualties and the greater presence of multiple injuries are new factors in the epidemiology of SCI after a road crash.
