神经根型颈椎病全球研究现状的可视化分析

Visual analysis of global research status of cervical spondylotic radiculopathy

摘要:

[目的] 分析神经根型颈椎病 （cervical spondylotic radiculopathy, CSR） 的全球研究现状。[方法] 通过 Wed of Sci- ence 核心合集数据库检索 1994 年—2021 年关于 CSR 的相关文献出版物，利用文献计量学的方法进行数据的分析与研究，使用文献计量在线网站、VOSviewer 软件进行分析及可视化转化，分析 CSR 每年论文发表趋势，国家、机构、作者和期刊的发表情况，以及关键词的聚类。[结果]本研究共纳入 2 748 篇文献，全球的文献发表量呈平稳增长的趋势，其中美国的贡献最大，其发表的文献数量最多，H 指数最高；中国的文献发表量排第 2，但 H 指数较低。发表量最多的机构是宾夕法尼亚大学；Winkelstein BA、Olmarker K 和 Kikuchi S 等教授在该领域取得了巨大的成就，然而，机构间或作者间的合作相对较少。在期刊方面，发表 CSR 研究论文最多的期刊是 Spine、World Neurosurgery、European Spine Journal。其中，Spine 不仅出版的文献数量最多，其 H 指数也远超其他期刊。通过热点关键词分析发现，弥散张量成像技术、前路椎间盘切除术、预后评分可能是当前的研究热点。[结论]CSR 的研究将会越来越多，美国在这一领域保持领先地位，各国间和作者间需要进一步加强合作。

Abstract:

[Objective] To analyze the global research status of cervical spondylotic radiculopathy (CSR). [Methods] The Wed of Sci- ence Core Collection database was used to retrieve literature on CSR from 1994 to 2021. Retrieval data were statistically analyzed by biblio- metrics method and two bibliometric tools were used to conduct visualization and knowledge maps, including the bibliometrics online site and VOS viewer software. Annual trends of publications, contributions of countries, institutions, authors and journals, and clustering of key- words were analyzed. [Results] A total of 2 748 publications were included. The number of annual publications has shown an increasing trend worldwide. The United States has made the greatest contribution, with the largest number of publications and the highest H-index. Chi- na ranked second in the number of publications, but its H-index was relatively low. The most prolific institutions was University of Pennsyl- vania, and Professors Winkelstein BA, Olmarker K and Kikuchi S have made great achievements in this field. However, the collaboration be- tween international institutions or researchers was relatively low. Publications in Spine, World Neurosurgery and European Spine Journal ranked top three in terms of journals. Among them, Spine not only published the largest number of articles, but also had a far higher H-index than other journals. Through the analysis of hotspots, it was found that diffusion tensor imaging, anterior discectomy and prognosis score may be the current research hotspots. [Conclusion] There will be an increasing number of publications on cervical spondylotic radiculopathy re- search, and the United States stay ahead in this field. International collaboration needs to be further strengthened.
