Global incidence and prevalence of traumatic spinal cord injury

Abstract

This systematic review examines the incidence and prevalence of traumatic spinal cord injury (SCI) in different countries worldwide and their trends over time. The literature search of the studies published between 1950 and 2012 captured 1,871 articles of which 64 articles on incidence and 13 articles on prevalence fulfilled the inclusion and exclusion criteria. The global incidence of SCI varied from 8.0 to 246.0 cases per million inhabitants per year. The global prevalence varied from 236.0 to 1,298.0 per million inhabitants. In addition to regional differences regarding the prevalence rates of SCI across the globe, there has been a trend towards increasing prevalence rates over the last decades. Our results suggest a relatively broad variation of incidence and prevalence rates of SCI among distinctive geographic regions. These results emphasize the need for further studies on incidence and prevalence of SCI, and for international standards and guidelines for reporting on SCI.
