To evaluate the global research productivity in the field of discectomy for lumbar disc herniation (LDH) through bibliometric analysis and mapping knowledge domains.
A systematic literature search was performed on the Web of Science (WoS), including the Science Citation Index Expanded (SCIE) database and PubMed. The number of publications, countries of publications, journals of publications, total citation frequency, impact factors of journals, and Institutional sources were analyzed by Microsoft Excel 2019, the Online Analysis Platform of Bibliometrics, and VOSviewer. Hotspots were also analyzed and visualized based on VOSviewer.
A total of 2,066 papers were identified. The United States ranked first in the number of total citations (7,970). China ranked first in the number of publications (556, 26.9%), which has surpassed the United States in terms of the number of publications published annually since 2016. Wooridul Spine Hospital published the most papers (43). For journals, has published the largest number of papers (289) in this field with the most citation frequencies (6,607). Hotspots could be divided into three clusters: surgery, lumbar disc herniation, and diagnoses. The most recent topic that appeared was symptomatic re-herniation.
The United States is the most significant contributor to the development of discectomy for LDH. The current research focus of discectomy on LDH was the comparison between surgical approaches and evaluation of current minimally invasive discectomy. At present, minimally invasive techniques, such as endoscopic discectomy, cannot completely replace non-endoscopic discectomy (open discectomy and microdiscectomy) through bibliometric analysis and mapping knowledge domains.
通过文献计量分析和知识领域图谱绘制，评估腰椎间盘突出症（LDH）椎间盘切除术领域的全球研究生产力。
在科学网（WoS）上进行系统的文献检索，包括科学引文索引扩展版（SCIE）数据库和PubMed。使用Microsoft Excel 2019、文献计量在线分析平台和VOSviewer分析出版物数量、出版国家、出版期刊、总被引频次、期刊影响因子和机构来源。还基于VOSviewer对热点进行了分析和可视化。
共识别出2066篇论文。美国在总被引频次（7970次）方面排名第一。中国在出版物数量（556篇，占26.9%）方面排名第一，自2016年以来每年的出版物数量已超过美国。Wooridul脊柱医院发表的论文最多（43篇）。对于期刊， 在该领域发表的论文数量最多（289篇），被引频次最高（6607次）。热点可分为三个聚类：手术、腰椎间盘突出症和诊断。出现的最新主题是症状性复发。
美国是LDH椎间盘切除术发展的最重要贡献者。目前LDH椎间盘切除术的研究重点是手术方法之间的比较和当前微创椎间盘切除术的评估。目前，通过文献计量分析和知识领域图谱绘制，内镜下椎间盘切除术等微创技术不能完全取代非内镜下椎间盘切除术（开放椎间盘切除术和显微椎间盘切除术）。
