Introduction: International journals represent a forum for current information exchange with contributions from all over the world. Biobliometric analysis can indicate trends and patterns within scientific disciplines and highlight national and international strengths in various research areas. The number of articles published and their country of origin are important gauges of the level of research in that country and of a journalĀ“s influence and impact on scientific opinion worldwide.

Methods: Five spine journals (Spine, The Spine Journal, European Spine Journal, Journal of Spinal Disorders & Techniques and Journal of Neurosurgery: Spine) were included in this study. Data were obtained from the Web of Science database between the period of January 1993 and December 2012. Only original full manuscripts were tracked. The articles were quantified in four time intervals each consisting a consecutive 5-year period (1993-1997, 1998-2002, 2003-2007, 2008-2012). The results generated were ranked by countries/territories and further divided into seven geographic regions (North America, Europe, Asia, Australasia, South America, Africa and other).

Results: A total of 16,676 articles were indexed by Web of Science in these five spine journals over the last 20 years. There is a decrease in the percentage of articles from North America between the periods of 1993-1997 and 1998-2002 (p< 0.05) and between the periods of 1998-2002 and 2003-2007 (p< 0.05) but it stabilizes at 40% after 2007. Meanwhile, significant increases in the percentage of articles contributed by Asian countries were observed over all the time periods with a rate of 26% in 2008-2012 (p< 0.05 between periods of 1998-2002 and 2003-2007; p< 0.05 between periods of 2003-2007 and 2008-2012). Japan, China and South Korea were found to be the major contributors. The percentages of articles from the Europe and Australasia remain relatively stable at around 30% and 3% respectively whereas South America, Africa, and other countries/territories had only minor contributions throughout the study periods.

Conclusion: Our analysis indicates that over the last 20 years, the major spine journals have changed from the journals that primarily publish regional work i.e. from North America and Europe to ones that publish a more diverse and global scientific works. This analysis may also indicate that by proportion spine research productivity is evolving with significant increases from countries in Asia.
