[Visualization analysis of hydrogel spine research in the Web of Science core collection database]

To summarize research hotspots and predict future trends by conducting a bibliometric analysis of English literature in the field of hydrogels for spinal applications over the past decade.

Retrieve the English literature included in the Web of Science core collection database from 2012 to 2022, analyze the literature using Citespace 6.1.R6, and draw a visual graph.

A total of 84 articles were included, and the number of publications has been increasing year by year. The United States was the country with the highest number of publications, with David Eglin as the author and Univ Delaware as the institution with the highest number of publications, forming 10 meaningful clusters. The current research hotspots were the treatment of intervertebral disc degeneration, repair of the dura mater, and recovery after spinal cord injury.

In recent ten years, the research of hydrogel in the field of spine is very popular. It is predicted that the future research in the field of hydrogel spine will continue to deepen under the exploration of disc, 3D printing, cell, chondrocyte transplantation, gene expression and horn structure.
