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,...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。展开更多
