Thoracic ossification of the posterior longitudinal ligament (TOPLL) is a rare but intractable disease, and is the second leading cause of thoracic myelopathy. This study aimed to illustrate the overall knowledge structure and development trends of TOPLL, using a bibliometric analysis and newly developed visualization tools.
Research data sets were acquired from the Web of Science. The literature search was also limited to articles that were published until October 30, 2021. VOS viewer and Citespace software was provided to analyze the data and generate visualization knowledge maps. Annual trend of publications, distribution, H-Index status, co-authorship status, and research hotspots were analyzed.
A total of 206 publications met the requirement. Japan published most papers (92), both total citations (1574) and H-index (24) ranked first of all the countries. The most productive organization was Peking University (22). The most productive author was Yamazaki M (18). The most productive journal was Spine (33). Diagnosis and treatment on the accuracy of surgical segments, prognosis of patients, and gene research were the research hotspots in the recent years.
The study showed an upward trend with a stable rise in recent years. Japan is country with the highest productivity, not only in quality, but also in quantity. Peking University and Spine have been the largest contributors. Indeed, this study provides great insights to the growth and development of TOPLL. Moreover, it will contribute to the growth of the international frontier.
胸段后纵韧带骨化症（TOPLL）是一种罕见但难以治疗的疾病，是胸髓病的第二大主要原因。本研究旨在使用文献计量分析和新开发的可视化工具，阐明 TOPLL 的整体知识结构和发展趋势。
研究数据集取自 Web of Science。文献检索也仅限于截至 2021 年 10 月 30 日发表的文章。使用 VOS viewer 和 Citespace 软件分析数据并生成可视化知识图谱。分析了出版物的年度趋势、分布、H-指数状况、合著状况和研究热点。
共有 206 篇符合要求的论文。日本发表的论文最多（92 篇），总引文数（1574）和 H-指数（24）均居所有国家之首。最具生产力的组织是北京大学（22）。最有生产力的作者是 Yamazaki M（18）。最有生产力的期刊是 Spine（33）。近年来，诊断和治疗手术节段的准确性、患者预后和基因研究是研究热点。
研究显示呈上升趋势，近年来稳定上升。日本是生产力最高的国家，不仅在质量上，而且在数量上都是如此。北京大学和 Spine 一直是最大的贡献者。事实上，本研究为 TOPLL 的增长和发展提供了重要的见解。此外，它将有助于国际前沿的发展。
