Significant progress has been seen in the field of spine in recent years as a consequence of worldwide contributions. However, the national productivity to the field of spine is still unclear. The aim of this study was to investigate the national contributions in the field of spine.
Web of Science was searched for articles published in the five highly cited spine journals from 2009 to 2013, including The Spine Journal, European Spine Journal, Spine, Journal of Neurosurgery: Spine, and Journal of Spinal Disorders and Techniques. The number of total articles, the per capita numbers, impact factors, citations and funding source were recorded and analyzed.
A total number of 6920 articles were published in the five journals from 2009 to 2013 worldwide. North America, East Asia, and West Europe were the most productive world areas. High-income countries published 83.97% of articles, middle-income 16.01%, and lower-income just 0.01%. The United States published the most number of articles (35.79%), followed by China, Japan, South Korea, and Canada, and had the highest total impact factors and the highest total citations. However, when normalized to population size, Switzerland had the highest number of articles per million populations, followed by The Netherlands and Sweden.
The majority of the spine articles are published by authors from high-income countries while few publications from low-income countries. The United States is the most productive country in the field of spine. However, some European countries may be more productive when normalized to population size.
近年来，由于全球范围内的共同努力，脊柱领域取得了显著进展。然而，各国在脊柱领域的产出情况仍不明确。本研究旨在调查各国在脊柱领域的贡献。
在科学网中搜索2009年至2013年发表在五本高被引脊柱期刊上的文章，这些期刊包括《脊柱杂志》《欧洲脊柱杂志》《脊柱》《神经外科杂志：脊柱》以及《脊柱疾病与技术杂志》。记录并分析文章总数、人均文章数、影响因子、引用次数和资金来源。
2009年至2013年，全球这五本期刊共发表了6920篇文章。北美、东亚和西欧是产出最多的世界区域。高收入国家发表了83.97%的文章，中等收入国家发表了16.01%，低收入国家仅发表了0.01%。美国发表的文章数量最多（35.79%），其次是中国、日本、韩国和加拿大，其总影响因子和总引用次数最高。然而，按人口规模进行归一化后，瑞士每百万人口的文章数量最多，其次是荷兰和瑞典。
大多数脊柱领域的文章由高收入国家的作者发表，低收入国家的出版物很少。美国是脊柱领域产出最多的国家。然而，按人口规模进行归一化后，一些欧洲国家可能产出更高。
