The use of bibliometric analysis studies allows for the precise assessment of high impact contributions to various fields of study. A bibliometric assessment of academic works cited in filed patents enables tracking the academic studies which have been most influential in the development of new technologies in spine surgery.
The Lens database was utilized to retrieve scholarly articles related to the field of spine surgery, with special focus on spinal fusion and biologics. Scholarly works cited in patents were organized by publishing journal, article topic, study type, publishing institution, and authors information. Such publications were also categorized by country of origin and, for U.S. patents, region of origin.
The employed search criteria yielded 37,005 scholarly works related to spine surgery published between 1889 and 2022 and a total of 947 scholarly works cited in patents from 1968 to 2022. Many of the top contributing authors were orthopedic surgeons while the top 3 authors were biomedical engineers. The region in the U.S. with the most citations in patents and the most scholarly work overall was the middle-Atlantic region.
This patent bibliometric analysis provides a general overview of trends in publications impacting spine surgery innovation over time. Our results highlight top instutions and regional contributions to spine surgery innovation within the United States and worldwide. As the first patent bibliometric study providing data on the most technologically impactful scholarly work in spine surgery, this study has not only historical value in terms of documenting the scientific and intellectual property developments in spine surgery in the past 50 years, but also practical relevance insofar as the identified trends and research hotspots that may provide researchers valuable insights regarding future decisions involving research efforts and resources allocation.
文献计量分析研究有助于精确评估对各个研究领域的高影响力贡献。对已授权专利中引用的学术著作进行文献计量评估，能够追踪在脊柱外科新技术发展中最具影响力的学术研究。
利用Lens数据库检索与脊柱外科领域相关的学术文章，特别关注脊柱融合和生物制剂。专利中引用的学术著作按照发表期刊、文章主题、研究类型、发表机构和作者信息进行整理。这些出版物还按原产国分类，对于美国专利，则按原产地区分类。
所采用的检索标准产生了1889年至2022年间发表的37005篇与脊柱外科相关的学术著作，以及1968年至2022年间专利中引用的947篇学术著作。许多贡献最大的作者是骨科医生，而排名前三的作者是生物医学工程师。美国专利引用次数最多且总体学术著作最多的地区是大西洋中部地区。
这项专利文献计量分析提供了随着时间推移影响脊柱外科创新的出版物趋势的总体概述。我们的结果突出了美国国内和全球范围内对脊柱外科创新的顶尖机构和地区贡献。作为第一项提供脊柱外科领域最具技术影响力学术著作数据的专利文献计量研究，本研究不仅在记录过去50年脊柱外科的科学和知识产权发展方面具有历史价值，而且在已确定的趋势和研究热点方面具有实际意义，这些趋势和热点可能为研究人员在涉及研究工作和资源分配的未来决策中提供有价值的见解。
