BACKGROUND:Osteonecrosis of the femoral head is a severe disease that can lead to femoral head collapse and joint degeneration.It is characterized by severe hip pain,often affecting the knee and ipsilateral hip.Surgical intervention remains the primary treatment for advanced-stage osteonecrosis of the femoral head.However,research trends in this field are continuously evolving,and to date,no bibliometric analysis has been conducted to explore the research landscape.OBJECTIVE:To provide a comprehensive overview of global research trends,knowledge structures,and emerging hotspots in the surgical treatment of osteonecrosis of the femoral head from 2005 to 2024 through a bibliometric analysis.METHODS:Publications related to the surgical treatment of osteonecrosis of the femoral head from September 1,2005,to September 1,2024,were retrieved from the Web of Science Core Collection(WoSCC)and China National Knowledge Infrastructure(CNKI)databases.VOSviewer,CiteSpace,and the R package"Bibliometrix"were used for the bibliometric analysis.RESULTS AND CONCLUSION:(1)After filtering and deduplication of the literature based on specific keywords,539 relevant publications from the WoSCC database and 1 039 from the CNKI database were included in the bibliometric analysis.(2)In the WoSCC database,China and the United States were the leading countries in publication volume.The overall number of publications showed an upward trend from 2005 to 2024,with peaks in 2016 and 2022.The leading research institutions included Shanghai Jiao Tong University,Sichuan University,the Hospital for Special Surgery(HSS),and Peking University.The most popular journals in this field were J PEDIATR ORTHOP,CLIN ORTHOP RELAT RES,and J ORTHOP SURG RES.J BONE JOINTSURG AM,CLIN ORTHOP RELAT R,and J BONE JOINT SURG BR were the most frequently cited journals.The publications were authored by 2 498 researchers,with HE WEI,SIEBENROCK,KLAUS A,KLINGELE,KEVIN E,and SUN WEI being the most prolific authors.Articles by MONT MA,LIEBERMAN JR,DELANOIS RE,and MARKER DR had the highest citation counts.The primary topics and emerging research hotspots in osteonecrosis of the femoral head surgical treatment were reflected by keywords such as avascular necrosis,hip,and femoral head.(3)In the CNKI database,the leading institutions were the Department of Orthopedics at Shanghai Jiao Tong University Affiliated Sixth People's Hospital(8 articles),the Department of Orthopedics at Union Hospital of Huazhong University of Science and Technology(7 articles),and the Department of Orthopedics at Wangjing Hospital of China Academy of Chinese Medical Sciences(7 articles).The journals Chinese Journal of Orthopaedic Surgery(36 articles)and Chinese Journal of Bone and Joint Injury(36 articles)had the highest publication volumes.The top three prolific authors were HE WEI(14 articles),CHEN WEIHENG(9 articles),and LIU XINWEI(5 articles).The top five keywords were surgical treatment(49 occurrences),internal fixation(25 occurrences),treatment(23 occurrences),review(22 occurrences),and core decompression(22 occurrences).(4)This is the first bibliometric study to comprehensively summarize the research trends and advancements in the surgical treatment of osteonecrosis of the femoral head.These findings highlight recent research frontiers and emerging hotspots,providing a foundation for academic research and insights for clinical decision-makers.

BACKGROUND:Finite element analysis is a kind of analysis method widely used in the field of engineering technology,but because of its characteristics of high precision analysis of complex structures,the application of finite element analysis in the field of orthopedics is also increasing year by year.In recent ten years,numerous achievements have been made in the study of femoral head necrosis by finite element analysis at home and abroad.However,the analysis of current research status and hot trends is still lacking.OBJECTIVE:To visually analyze research status and hotspot of finite element method in the field of femoral head necrosis in recent years.METHODS:Articles related to finite element analysis of femoral head necrosis during 2014-2023 were selected from CNKI database and Web of Science database.Citespace 6.1.R6 visual analysis software was used to summarize the main research contents of relevant articles and draw the scientific knowledge graph such as the annual number of publications,author graph,co-citation papers and hot keywords for summary.RESULTS AND CONCLUSION:(1)After literature retrieval according to relevant keywords,Citespace software was imported.After software deduplication function was used to remove duplicate articles,Web of Science core collected 385 related articles and CNKI database 149 related articles.(2)The keyword co-occurrence analysis found that the keyword frequency ranking in Web of Science database in recent ten years was as follows:finite element analysis(163 times),femoral head(83 times),arthroplasty(44 times),fixation(40 times),and replacement(39 times);centrality ranking:finite element method(0.21),hip joint(0.21),stability(0.19),fixation(0.15),and contact pressure(0.15).(3)The ranking of keywords frequency in CNKI database in recent ten years was as follows:finite element analysis(91 times),biomechanics(45 times),femoral head necrosis(42 times),femoral neck fracture(33 times),internal fixation(16 times),and the centrality ranking was as follows:internal fixation(0.45),3D printing(0.44),Jianpi Huogu formula(0.43),three-dimensional reconstruction(0.42),and femur head necrosis(0.38).(4)In the past ten years,the research in the field of femoral head necrosis had developed from"static"to"dynamic"'at home and abroad.The overall process was basically similar,and the research on gait model and risk prediction was more in-depth.In addition,with the deepening of domestic scholars'research on traditional Chinese medicine,the curative effect of traditional Chinese medicine in the treatment of femoral head necrosis had also been well verified.In the past ten years,the fields of medical materials and computer technology can become the focus of research at home and abroad.(5)Although the research in related fields in China is relatively slow,more clinical studies are still needed to verify.However,with the progress of science and technology in China,it is believed that domestic scholars will truly apply the finite element analysis of femoral head necrosis to clinical practice in the future,and play a role in assisting patients with individualized treatment and improving long-term efficacy.
