Global Hotspots and Trends of Diabetic Foot Ulcer Therapy: A Bibliometric Analysis from 2004 and 2023.

Diabetic foot ulcer (DFU) is a common complication of diabetes, associated with increased rates of amputation and mortality. In recent years, great progress has been made in the treatment of DFU, but there is still a lack of bibliometric research on the treatment of DFU.DFU therapy publications published between 1 January 2004 and 31 December 2023 were retrieved from the Web of Science Core Collection (WoSCC) database for analysis using VOSviewer and CiteSpace analytics. A total of 4833 publications on DFU from 2004 to 2023 were included in the WoSCC database. The United States had the highest productivity with 1463 papers, accounting for 30.27% of the total production, followed by China with 907 papers (18.77%) and England with 438 papers (9.06%). In terms of research institutions and journals, the University of Texas System and Journal of Wound Care published the highest number of papers. High-frequency keywords in the field of DFU therapy mainly concentrated on management, wound healing, and amputation. This study conducted a systematic bibliometric analysis of DFU therapy publications from 2004 and 2025. Improving DFU management, promoting wound healing, and reducing amputation rates are the hotspots and future trends in this field. Our work provides valuable insights into the research trajectory and future avenues of exploration in the field of DFU therapy. These findings provide strong support for academic research and clinical practice.
