Objective:To analyze the indexed research literature of bioabsorbable screw on Web of Science

to reveal the research status and hotspots of bioabsorbable screw

and to provide a reference for researchers. Methods:The knowledge graph of biological absorbable screw literature was drawn by word frequency analysis

co-occurrence analysis

citation analysis

central degree analysis and social network analysis methods based on Web of Science database. The deadline was June 2014. The annual number of papers

keywords

countries of the papers

research direction and posting journal were analyzed. The maps of the co-authors were drawn to reveal the main academic cooperation groups in the field. The maps of literature co-citation were drawn to reveal the knowledge base of such research field. The knowledge maps of agency cooperation were drawn to reveal the research institutions of international cooperation in such research field. Results:Totally 1 489 bibliography and 27 150 quotation were obtained by retrieving and screening. The research papers on bioabsorbable screw were largely from the United States

followed by Germany

Finland and China; and the research focus was mainly on screw material

screw forming method and clinical study of screws. Author cooperation group dominated by Tormala P

Bostman O

Ashammakhi N

Rokkanen P

Pohjonen P has larger number and higher frequency of cooperation. Co-citation analysis and centrality analysis revealed that the research by Finnish scholar Bostman O formed the basis of literature research in this field.For the international agencies cooperation

two main international cooperation groups between University of Helsinki and Tampere University of Technology as well as between Harvard University and University of Pittsburgh were formed. Conclusion:China has great research potential in bioabsorbable screw

however

the domestic and international cooperation between researchers and institutions should be enhanced.
