Unilateral biportal endoscopic in spine surgery: a global bibliometric analysis of research trends and influences

Purpose: Unilateral biportal endoscopic (UBE) technique is increasingly utilized in spine surgery, offering minimally invasive solutions with promising outcomes. This study conducts a comprehensive bibliometric analysis of global research trends and key influences in UBE application. Methods: A systematic search in the Web of Science Core Collection was performed on June 9, 2024, focusing on English publications related to UBE and spine surgery. Bibliographic data were analyzed using R and VOSviewer to visualize trends, collaborations, and citation networks. Results: A total of 231 articles from 59 sources were identified, with World Neurosurgery being the most prolific journal. Publications peaked in 2023, with South Korea and China leading the field through significant collaborations. HEO DH emerged as the most productive and cited author. Key research focuses included “decompression,” “surgery,” and “discectomy.” Conclusion: The analysis highlights increasing research interest in UBE, with key contributors and collaborations shaping advancements. It provides insights into research trends, main areas of focus, and emerging topics, guiding future UBE research and applications. © 2025 Elsevier B.V., All rights reserved.
