Visualization analysis of 3D printing technology in spinal surgery

English Keywords:3D printing  Spine  Visualization analysis

English Abstract:

  【Abstract】 Objectives: To visualize and analyze the research on the application of 3D printing technology in the field of spinal surgery at home and abroad, construct visualization maps, and provide reference for future research by comparing the research hotspots at home and abroad. Methods: The China National Knowledge Infrastructure(CNKI) database was searched using the keywords of "3D printing" and "spine" for literature published in 2013-2023 in Chinese; The Web of Science Core Collection database was used as English database, literature published in 2013-2023 with topics including "3D printing" and "Spine" were searched with "TS=(3D printing) AND TS=(Spine)". A total of 256 Chinese literature and 250 English literature were included and imported into CiteSpace software after excluding the duplicate and low relevance articles. The annual publication quantity, authors, keywords, countries, institutions, keyword clustering, and keyword prominence in both Chinese and English literature were visualized and analyzed. Results: The annual publication numbers of domestic and foreign publications from 2013 to 2023 were similar. The top three authors published the most Chinese literature were Li Chao, Niu Guoqi, and Sun He; The top three authors published the most English literature were Clifton William, Damon Aaron, and Nottmeier Eric. In the visualization map of Chinese literature keywords, there were 215 nodes and 617 lines with a density of 0.0273; The most frequently appeared keywords were 3D printing(148 times, 1.09), spinal surgery(47 times, 0.26), and scoliosis(30 times, 0.10). In the English literature keyword visualization graph, there were 282 nodes and 1359 lines with a density of 0.0367; The most frequently appeared keywords were 3D printing(116 times, 0.07), surgery(54 times, 0.12), and accurate(42 times, 0.18). A total of 206 nodes and 100 lines with a density of 0.0047 appeared in the visualization graph of the institutions of CNKI database, and 216 nodes and 147 lines appeared in the visualization graph of the institutions of Web of Science with a density of 0.0063. China published the most articles, followed by the United States and Australia. The top three institutions published the most Chinese literature were Peking University Third Hospital, Yan′an University Affiliated Hospital, and Bengbu Medical College Second Affiliated Hospital. The top three institutions published the most literature abroad were Mayo Clin, Southern Med Univ, and Capital Med Univ. After clustering the keywords of Chinese and English literature, 6 meaningful clusters were obtained respectively. The most prominent keywords in Chinese and English literature were tissue engineering and patient specific, respectively. Conclusions: The hot topics of 3D printing technology in spinal surgery research vary in countries. The connections between foreign institutions are relatively dense, while those in China are relatively scattered.
