Highly-Cited Papers on Fracture Non-union - A Bibliometric Analysis of the Global Literature (1990-2023)

Objective

The growing interest in this field of fracture nonunion has been informally acknowledged through published studies. A bibliometric analysis was conducted to objectively outline the patterns in published clinical research concerning nonunion fractures by utilizing highly cited papers (HCPs).

Methods

Through a predetermined search strategy, we gathered literature on the clinical management of nonunion fractures from the Scopus database and utilized bibliometrics to examine the publication dates, countries, institutions, journals, authors, HCPs, and research focal points. Statistical analysis and visualization were conducted using MS Excel and VOSviewer software.

Results

From 1990 to 2023, a total of 168 HCPs in the field of fracture nonunion were identified. They received an average of 167.68 citations per paper (CPP). Among them, 4.08% received external funding, while 17.26% were involved in international collaboration. The United States (49.4% share) was the most productive country and France had the highest citation impact. P.V. Gianoudis had the highest productivity with 13 publications and P. Hernigou had the highest citation impact. The Mayo Clinic was the most productive organization and Hopital Henri Mondor achieved the highest citation impact. The most productive journal was Clinical Orthopedics & Related Research, and the Journal of Bone & Joint Surgery, American Volume had the highest average citation impact.

Conclusion

This contemporary bibliometric study illustrates the research features and developments of nonunion fractures. Through the use of VOSviewer, key countries, organizations, and authors could be identified, providing researchers with essential information to pinpoint current and future areas of interest in fracture nonunion.

Scientometric analysis of global research on delayed and nonunion of fractures (2004-2023): Insights from the Web of Science core collections

BACKGROUND AND AIMS

Nonunion of fractures continue to be the most challenging complication. The increased interest in this area has been anecdotally recognized through published research. The study aimed to conduct a comprehensive bibliometric analysis of global research on nonunion and delayed union of fractures to identify key trends, hotspots, and potential areas for future research development.

METHODS

Using a pre-defined search strategy, articles related to "Nonunion and Delayed Union of Fractures" that were published from January 1st, 2004 to December 31st, 2023, were retrieved from the Web of Science Core Collection for scientometric analysis. The bibliometrics method was used to analyze the publication dates, countries, institutions, journals, authors, highly cited literature and research hotspots.

RESULTS

A total of 1997 publications were identified, which registered an average of 21.42 citations per paper (CPP). The 30.39 % and 3.55 % of the 1997 global publications have received external funding support and were highly-cited papers, respectively. The USA, China and UK, were the most productive countries, while Canada, Scotland, and Belgium registered the highest citation impact. University Leeds, Shanghai Jiao Tong University and Kobe University were the most productive organizations, while Vanderbilt University, University of Edinburgh and University Leeds registered the highest citation impact. Giannoudis PV, Egol KA, and Konda SR were the most productive authors, while Bhandari M, Mehta S, and Schemitsch EH registered the highest citation impact. Injury, Journal of Orthopaedic Trauma and Archives of Orthopaedic and Trauma Surgery contributed the most papers, while Journal of Bone and Joint Surgery-American, Injury and Clinical Orthopaedics and Related Research registered the highest citation impact per paper.

CONCLUSION

The present bibliometric analysis shows the characteristics and trends of non-union fracture research and illuminates the current research situation and developmental trends.

Global Stem Cell Research in Orthopaedics: A Bibliometric Study from 1995 to 2020

Background

The research field of stem cell-based therapies in orthopaedics has witnessed significant growth in the recent past. We aimed to identify and analyze the bibliometric characteristics of the global highly cited papers (HCPs) in stem cell research in orthopaedics.

Methods

This study relied on secondary data extracted from Scopus, Elsevier's abstract and citation database. An advanced search string was employed, for the period from 1995 to 2020. For each paper, the extracted information included the number of citations, title, authors (name, number, authorship position, and country), year of publication, title of the journals, study design, and thematic field. The VOSviewer (1.6.20) was used to uncover relationships between authors, institutions, keywords, and publications.

Results

There were a total of 1427 publications and out of these 186 papers had 100 or more citations (range 100-2644) and were considered as HCPs. The average citation per paper (CPP) was 265.8. Only 4% of the top HCPs contributed 20% of the total citations of all HCPs. All the HCPs were published from high-income countries, and the USA was the leading country in all aspects of publication on stem cell research. Méndez-Ferrer S registered the highest citation (n = 2644), Prockop DJ was the most prolific author (n = 8 papers), and Harvard Medical School, USA emerged as the most prolific organization with 12 HCPs.

Conclusion

Global research in stem cell therapies for orthopaedic problems is making strides, and is an emerging field of research. Stem cell research offers the potential for improved treatment outcomes for various musculoskeletal conditions.

Global research output and highly-cited publications on prosthetic joint infections: A bibliometric analysis (2003-2022)

Backgroundand aims

Prosthetic Joint Infection (PJI) is a serious clinical problem after Arthroplasty. The research field on PJI is emerging, but there is a paucity of information on the most impactful publications on it. This prompted us to conduct a bibliometric analysis of the global research output, from 2003 to 2022, to identify the growth of publications, the key players in this research field and to evaluate the characteristics of highly-cited publications (HCPs) on the PJI.

Methods

Publications related to PJI research were identified globally from the Scopus database, using specific keywords, covering the literature from 2003 to 2022. The HCPs were considered those with 100 or more citations. Information on publication year, citation count, funding sources, title, author, journal, country, institution, research area, and strategic keywords were collected from these HCPs. Publication data was imported into Microsoft Excel and analyzed further using VOSviewer and R software.

Results

There were 182 HCPs (3.12%), which received a total citation of 124701 (average CPP of 21.41), with the citation range from 100 to 1921. Research articles were the most predominant publications (69.2%), but their average citations per paper (CPP) of 189.78 was lower than that of Review articles (average CPP: 253.17). The USA has been the leading country in terms of total publications (31.58%), and HCPs (36.99%), followed by Switzerland, Spain, UK and China. There were no HCPs from developing countries. J. Parvizi of Thomas Jefferson University, USA (with a total publications of 31 and an average CPP of 315.7), and W. Zimmerli of Basel University, Switzerland (with a TP of 11 and an average CPP of 341.9), were the most productive and impactful authors in PJI global research output.

Conclusion

This bibliometric analysis identified the most productive and impactful authors, organizations, countries, and journals in the research of PJI, of the last two decades.
