To perform a bibliometric analysis of publications rates in orthopedics in the top 15 orthopaedic journals.
Based on their 2015 impact factor, the fifteen highest ranked orthopaedic journals between January 2010 and December 2014 were used to establish the total number of publications; cumulative impact factor points (IF) per country were determined, and normalized to population size, GDP, and GDP/capita, comparison to the median country output and the global leader.
Twenty-three thousand and twenty-one orthopaedic articles were published, with 66 countries publishing. The United States had 8149 publications, followed by the United Kingdom (1644) and Japan (1467). The highest IF was achieved by the United States (24744), United Kingdom (4776), and Japan (4053). Normalized by population size Switzerland lead. Normalized by GDP, Croatia was the top achiever. Adjusting GDP/capita, for publications and IF, China, India, and the United States were the leaders. Adjusting for population size and GDP, 28 countries achieved numbers of publications to be considered at least equivalent with the median academic output. Adjusting GDP/capita only China and India reached the number of publications to be considered equivalent to the current global leader, the United States.
Five countries were responsible for 60% of the orthopaedic research output over this 5-year period. After correcting for GDP/capita, only 28 of 66 countries achieved a publication rate equivalent to the median country. The United States, United Kingdom, South Korea, Japan, and Germany were the top five countries for both publication totals and cumulative impact factor points.
对排名前15的骨科期刊中骨科领域的发表率进行文献计量分析。
根据2015年影响因子，选取2010年1月至2014年12月间排名前15的骨科期刊，确定发表文章总数；计算每个国家的累积影响因子点数（IF），并根据人口规模、国内生产总值（GDP）和人均GDP进行标准化，与中位数国家产出及全球领先国家进行比较。
共发表了23021篇骨科文章，来自66个国家。美国发表了8149篇，其次是英国（1644篇）和日本（1467篇）。美国（24744）、英国（4776）和日本（4053）的影响因子最高。按人口规模标准化后，瑞士领先。按GDP标准化后，克罗地亚表现最佳。在考虑出版物数量和影响因子并根据人均GDP进行调整后，中国、印度和美国领先。在考虑人口规模和GDP后，28个国家的出版物数量至少与中位数学术产出相当。仅考虑人均GDP时，只有中国和印度的出版物数量达到与当前全球领先国家美国相当的水平。
在这5年期间，5个国家贡献了60%的骨科研究成果。在考虑人均GDP后，66个国家中只有28个国家的发表率与中位数国家相当。美国、英国、韩国、日本和德国在出版物总数和累积影响因子点数方面位列前五。
