ABSTRACT Retrospective population-based epidemiological study.
To assess the prevalence and temporal trends in the incidence of traumatic spinal cord injuries (TSCI), and demographic and clinical characteristics of an unselected, geographically defined cohort in the period 1952-2001.
The patients were identified from hospital records. Crude rates and age-adjusted rates were calculated for each year. The multivariate relationship between cause of injury, age at injury, decade of injury and gender was examined using a Poisson regression model.
Of 336 patients, 199 patients were alive on 1 January 2002, giving a total prevalence of 36.5 per 100,000 inhabitants. The average annual incidence increased from 5.9 per million in the first decade to 21.2 per million in the last. Mean age at injury was 42.9 years and the male to female ratio 4.7:1. Fall was the most common cause of injury (45.5%), followed by motor vehicle accidents (MVA) (34.2%). The incidence of MVA-related injuries increased during the observation period, especially among men <30 years. The lesion level was cervical in 52.4%, thoracic in 29.5% and lumbar/sacral in 18.2%. The lesion was clinically incomplete in 58.6% and complete in 41.4%. The incidence of fall-related injuries and the proportion of incomplete cervical lesions increased during the observation period, especially among men >60 years.
The incidence of TSCI has increased during the past 50 years. Falls and MVA are potentially preventable causes. The increasing proportion of older patients with cervical lesions poses a challenge to the health system.

    ABSTRACT: Spinal cord injury (SCI) is a traumatic event that impacts a patient's physical, psychological, and social well-being and places substantial financial burden on health care systems. To determine the true impact of SCI, this systematic review aims to summarize literature reporting on either the incidence or prevalence of SCI.

    ABSTRACT: Study design:Population-based prospective study.Objectives:To determine the incidence and evaluate the characteristics of newly injured patients with traumatic spinal cord injury (TSCI) admitted to two of the three national spinal cord injury (SCI) centers during the first year after the centralization of SCI care in Finland.Setting:Oulu and Tampere University Hospital SCI centers, Finland.Methods:The designated rehabilitation teams evaluated all of the patients with a new SCI and persisting neurological symptoms. The data were recorded according to the International Spinal Cord Injury Core Data Set.ResultsIn a 1-year period, 77 new patients with TSCI were admitted to the study centers serving a population of 3 065 946. In the whole catchment area, the mean annual incidence of TSCI was 25.1 per million, and in the hospital districts of the SCI centers, the incidence was even higher, at 38.1 per million. The mean age of the patients was 58.7 years. Falls were the leading cause of injury (64.9%), and the injury resulted in tetraplegia in 70.1% of the cases. Alcohol use was a contributing factor in 39% of the cases in the entire sample and in 58.6% of cases among patients aged younger than 60 years.Conclusion The incidence rates of TSCI were markedly higher than expected, demonstrating the previously hidden morbidity. The epidemiological features of TSCI appeared to follow the trends in developed countries, highlighting the increasing incidence of cervical lesions due to falling among the elderly. The results need to be confirmed in an extended follow-up.Spinal Cord advance online publication, 12 August 2014; doi:10.1038/sc.2014.131.

    ABSTRACT: Road collisions remain the leading cause of traumatic spinal cord injury (TSCI) in the world. Half of all TSCIs in Ireland in 2000 were caused by road collisions. Since then, there has been a downward trend in road fatalities coincident with implemented road safety strategies. To examine the incidence of TSCI resulting from road collisions from 2001 to 2010. This is a retrospective study using the hospital inpatient enquiry database of the tertiary referral center, which houses the national spinal injuries unit. Information retrieved included total numbers of patients with TSCI and number of TSCIs due to road collisions from 2001 through 2010, age groups affected, and the gender balance. Over the 10-year period studied, the incidence rate of TSCI due to road collisions declined, although this did not reach statistical significance. The largest numbers of all TSCIs and TSCIs due to road collisions were in the 20- to 29-year age category and the male gender. As mortality due to road collisions declined, so did the number of TSCIs from the same etiology. An impactful road safety campaign is likely to have influenced these trends.
