黄韧带骨化研究热点及趋势的可视化分析

Visual analysis of hot spots and trends in the study of ligamentum flavum ossification

背景:既往认为黄韧带骨化在人群中罕见发生,随着研究深入,发现其发病率逐渐上升,这引起大量学者的研究兴趣。目的:通过检索科学引文索引数据库核心集自1999年以来的有关黄韧带骨化的研究成果,使用文献计量学方法对数据进行可视化分析,回顾黄韧带骨化的研究历史,指示重要文献,梳理研究热点,为学者寻找研究方向提供思路。方法:以Web of Science核心集数据库为主,搜索并筛选黄韧带骨化相关论文,使用VOSviewer 1.6.19和CiteSpace 6.2.R6软件对年度发文量、研究国家、机构、被引文献、期刊、作者和关键词等进行可视化分析。结果与结论:①共纳入347篇文献,自1999年发文量呈螺旋上升,中国研究较日本起步晚,但是发文量后来居上,北京大学是发文量最多的机构,北京大学的陈仲强教授是发文量最多的学者。②被引用最多的10篇文献中5篇都与黄韧带骨化的手术治疗有关。③去除与研究主题直接相关的关键词,综合词频和中介中心性的结果发现,“胸椎脊髓病”“硬膜骨化”“微创手术”“后纵韧带骨化”处于领域研究的核心地位。④关键词聚类分析显示,黄韧带骨化的临床表现和手术治疗在疾病的研究中占比较大。⑤关键词时间线图及关键词突现分析显示,“微创手术”作为关键词出现在2015年前后,是突现强度最高的关键词,也是突现开始时间最晚的关键词,2019年开始受到学者广泛关注,关键词“硬膜骨化”的突现尚未结束。⑥黄韧带骨化的手术治疗一直处于研究前沿,微创手术方式的开发和研究、黄韧带骨化继发硬膜骨化的研究是该领域的研究热点。

BACKGROUND:Ossification of the ligamentum flavum was previously considered to be rare in the population.As research has progressed,its incidence rate is increasing gradually,which has aroused the interest of a large number of researchers.OBJECTIVE:To visualize and analyze the research results on ossification of the ligamentum flavum from the Web of Science Core Collection since 1999 using bibliometric methods,and to review the research history of ossification of the ligamentum flavum,highlighting important literature,summarizing research hotspots,and providing ideas for researchers to find research directions.METHODS:Using the Web of Science Core Collection as the data source,relevant papers on ossification of the ligamentum flavum were searched and screened.VOSviewer 1.6.19 and CiteSpace 6.2.R6 were used to conduct the visual analysis of annual publication volume,research countries,institutions,citations,journals,authors,and keywords.RESULTS AND CONCLUSION:(1)A total of 347 papers were included.Since 1999,the number of published papers has increased in a spiral pattern.China’s research started later than Japan’s,but the number of publications has come up later,with Peking University being the institution with the most publications,and Prof.Chen Zhongqiang from Peking University being the scholar with the most publications.(2)Five of the 10 most frequently cited publications were related to the surgical treatment of the disease.(3)Excluding keywords directly related to the research topic and synthetically analyzing frequencies and betweenness centralities of key words,terms such as“thoracic myelopathy,”“dural ossification,”“minimally invasive surgery,”and“ossification of the posterior longitudinal ligament”occupied a central position in this field.(4)Keywords clustering analysis showed that clinical manifestations and surgical treatment of ossification of the ligamentum flavum accounted for a large proportion of study.(5)The timeline and burst analysis of keywords revealed that“minimally invasive surgery”appeared as a keyword around 2015,with the highest burst strength and the latest burst start time,and began to receive extensive attention from researchers in 2019.The burst of the keyword“dural ossification”has not yet ended.(6)Surgical treatment for ossification of the ligamentum flavum has been at the forefront of research.Development and research of minimally invasive surgery and research on dural ossification secondary to ossification of the ligamentum flavum are both current research hotspots and possible future research trends.
