In recent years, there has been increased interest in the use of ultrasound technology in the evaluation of spinal and paraspinal regions.
This study aimed to investigate trends in spinal ultrasound research from 1994 to 2015 and compare the contributions of such research from different countries and authors.
Bibliometric analysis.
Publications related to spinal ultrasound from 1994 to 2015 were retrieved from the Web of Science database.
Excel 2013, GraphPad Prism 5, and VOSviewer were used to summarise bibliometric features, including the number of publications, citation frequency, H-index, and country contributions and hotspots (keywords of popular scientific fields).
A total of 3859 papers were included. The global inflection point (the point in time when the publication growth rate moved from positive to negative) came in 2010. The United States contributed the largest percentage of articles (1041; 26.9%), with the most citations (19 848) and the highest H-index (61). The journals and had the highest publication number. The University of Toronto and the University of California, San Francisco were the most contributive institutions. Studies could be divided into three clusters: surgery, osteoporosis, and others. The keywords 'adolescent idiopathic scoliosis' and 'anaesthesia' were the latest hotspots, appearing around 2012.
Spinal ultrasound literature has grown continuously over the last 22 years, with the rate slowing down after 2010. The United States was the largest contributor in this field. Recent studies on topics related to 'adolescent idiopathic scoliosis' and 'anaesthesia' were relatively new and should be closely followed in spinal ultrasound research.
近年来，超声技术在脊柱及脊柱旁区域评估中的应用受到越来越多的关注。
本研究旨在调查1994年至2015年脊柱超声研究的趋势，并比较不同国家和作者在该研究中的贡献。
文献计量分析。
从科学网数据库中检索1994年至2015年与脊柱超声相关的出版物。
使用Excel 2013、GraphPad Prism 5和VOSviewer总结文献计量特征，包括出版物数量、被引频次、H指数、国家贡献和热点（热门科学领域的关键词）。
共纳入3859篇论文。全球拐点（出版物增长率从正变为负的时间点）出现在2010年。美国贡献的文章数量最多（1041篇；26.9%），被引次数最多（19848次），H指数最高（61）。《 》和《 》杂志的出版物数量最多。多伦多大学和加利福尼亚大学旧金山分校是贡献最大的机构。研究可分为三个聚类：手术、骨质疏松症和其他。关键词“青少年特发性脊柱侧凸”和“麻醉”是最新热点，大约在2012年出现。
在过去22年中，脊柱超声文献持续增长，2010年后增速放缓。美国是该领域最大的贡献者。近期关于“青少年特发性脊柱侧凸”和“麻醉”相关主题的研究相对较新，在脊柱超声研究中应密切关注。
