Objective To understand the research status and progress of the application materials of traditional Chinese medicine small splint for the fixation of distal radius fractures and the pressure under splint,provide reference and guidance for further follow-up research.Methods Relevant literature included in CNKI,Wanfang,VIP and Pubmed from the establishment of the database to May 30,2023 was searched.CiteSpace software was used for visualization analysis,and the knowledge map of keywords,research institutions and authors was drawn.Results A total of 212 articles were included.The largest number of articles was published in 2014 and 2017,210 articles were published by Chinese people,and 2 articles were published by the Netherlands and Belgium.The top three regions in terms of the number of articles were Guangdong,Jiangsu and Zhejiang.China Journal of Orthopedics and Traumatology of Traditional Chinese Medicine had the largest number of articles.The research institution Nanjing University of Chinese Medicine published the most papers.The most studied splint materials were"wood splint","paper splint","fir bark","bamboo splint"and"3D printing"."Modified splint","micro-film","tension monitoring","pressure sensing","radial shortening","pad pressure",and"monitoring"were the research hotspots in 2023.Conclusion At present,the most widely used plywood materials are paper,Chinese fir bark and bamboo,and the research heat has not decreased.At present,researchers have made many innovations and improvements to small splints,including adjustable,monitorable,multi-module,and non-invasive.In addition,the application of pressure sensing of micro-films to study the biomechanics of small splint fixation of distal radius fractures is a current research hotspot.In the future,the application of film pressure tester to quantify and intelligent monitor the pressure of splints with different application materials,improved and innovative in different ages and physique should be an important research direction in the future,which is an important step in the transformation of basic research results to clinical practice.
