The study aimed to conduct a bibliometric analysis of publications concerning lumbar spondylolisthesis, as well as summarize its research topics and hotspot trends with machine-learning based text mining.
The data were extracted from the Web of Science Core Collection (WoSCC) database and then analyzed in Rstudio1.3.1 and CiteSpace5.8. Annual publication production and the top-20 productive authors over time were obtained. Additionally, top-20 productive journals and top-20 influential journals were compared by spine-subspecialty or not. Similarly, top-20 productive countries/regions and top-20 influential countries/regions were compared by they were developed countries/regions or not. The collaborative relationship among countries and institutions were presented. The main topics of lumbar spondylolisthesis were classified by Latent Dirichlet allocation (LDA) analysis, and the hotspot trends were indicated by keywords with strongest citation bursts.
Up to 2021, a total number of 4,245 articles concerning lumbar spondylolisthesis were finally included for bibliometric analysis. Spine-subspecialty journals were found to be dominant in the productivity and the impact of the field, and SPINE, EUROPEAN SPINE JOURNAL and JOURNAL OF NEUROSURGERY-SPINE were the top-3 productive and the top-3 influential journals in this field. USA, Japan and China have contributed to over half of the publication productivity, but European countries seemed to publish more influential articles. It seemed that developed countries/regions tended to produce more articles and more influential articles, and international collaborations mainly occurred among USA, Europe and eastern Asia. Publications concerning surgical management was the major topic, followed by radiographic assessment and epidemiology for this field. Surgical management especially minimally invasive technique for lumbar spondylolisthesis were the recent hotspots over the past 5 years.
The study successfully summarized the productivity and impact of different entities, which should benefit the journal selection and pursuit of international collaboration for researcher who were interested in the field of lumbar spondylolisthesis. Additionally, the current study may encourage more researchers joining in the field and somewhat inform their research direction in the future.
本研究旨在对有关腰椎滑脱的出版物进行文献计量分析，并通过基于机器学习的文本挖掘总结其研究主题和热点趋势。
数据从科学网核心合集（WoSCC）数据库中提取，然后在Rstudio1.3.1和CiteSpace5.8中进行分析。获取年度出版物产量以及随时间变化的前20位高产作者。此外，对前20位高产期刊和前20位有影响力的期刊按是否属于脊柱亚专业进行比较。同样，对前20位高产国家/地区和前20位有影响力的国家/地区按是否为发达国家/地区进行比较。展示国家和机构之间的合作关系。通过潜在狄利克雷分配（LDA）分析对腰椎滑脱的主要主题进行分类，并通过具有最强引文爆发的关键词指示热点趋势。
截至2021年，最终纳入4245篇有关腰椎滑脱的文章进行文献计量分析。发现脊柱亚专业期刊在该领域的生产力和影响力方面占主导地位，《脊柱》《欧洲脊柱杂志》和《神经外科杂志 - 脊柱分册》是该领域产量最高和影响力最大的前3种期刊。美国、日本和中国的出版物产量占比超过一半，但欧洲国家似乎发表了更具影响力的文章。似乎发达国家/地区倾向于发表更多文章且更具影响力的文章，国际合作主要发生在美国、欧洲和东亚之间。有关手术治疗的出版物是该领域的主要主题，其次是影像学评估和流行病学。过去5年中，腰椎滑脱的手术治疗尤其是微创技术是近期热点。
本研究成功总结了不同实体的生产力和影响力，这将有利于对腰椎滑脱领域感兴趣的研究人员进行期刊选择和寻求国际合作。此外，本研究可能会鼓励更多研究人员加入该领域，并在一定程度上为他们未来的研究方向提供参考。
