Abstract

PURPOSE

To compare orthopedics publications from USA, Japan and China.

METHODS

Scientific papers belong to ''Orthopedics'' category of Science Citation Index Expanded subject categories were retrieved from the "PubMed'' and ''Web of Knowledge'' online databases.

RESULTS

In the field of orthopedics, the annual number increased significantly from 2000 to 2012 in the three countries (p<0.001). The share of articles increased significantly in China, but decreased significantly in Japan and USA (p<0.05). In 2012, USA contributed 35.3% of the total world output in orthopedics field and ranked 1st; Japan contributed 5.9% and ranked 4th; China contributed 5.2% and ranked 5th. Publications from USA had the highest accumulated IFs and the highest total citations of articles (USA > Japan > China, p<0.001). Average IF from USA was much higher than Japan and China (p<0.001). USA published the most articles in the top ten orthopedics journals (USA (14355) > Japan (1702) > China (487), p<0.01).

CONCLUSION

Although China has undergone significant increase in annual number and percentage of scientific publication in orthopedics journals, it still lags far behind USA and Japan in the field of orthopedics in terms of quantity and quality.

摘要

目的

比较美国、日本和中国的骨科领域出版物。

方法

从“PubMed”和“Web of Knowledge”在线数据库中检索属于科学引文索引扩展版学科分类中“骨科”类别的科学论文。

结果

在骨科领域，这三个国家从2000年到2012年年发表量均显著增加（p<0.001）。中国的文章占比显著增加，而日本和美国的占比显著下降（p<0.05）。2012年，美国在骨科领域的世界总产出中占35.3%，排名第一；日本占5.9%，排名第四；中国占5.2%，排名第五。美国出版物的累积影响因子最高，文章的总被引次数也最高（美国>日本>中国，p<0.001）。美国的平均影响因子远高于日本和中国（p<0.001）。美国在前十种骨科期刊上发表的文章最多（美国（14355篇）>日本（1702篇）>中国（487篇），p<0.01）。
