A Bibliometric and Visual Analysis of the Most Cited Articles on Disc Arthroplasty

STUDY DESIGN: Bibliometric literature review. OBJECTIVE: Total disc arthroplasty (TDA) is an evolving technique used by surgeons to preserve neural elements and range of motion in patients with degenerative disc disease, spondylosis and more. In comparison to discectomy, disc arthroplasty has been shown to decrease morbidity, reduce adjacent-level disease, and preserve pre-operative range of motion. The objective of this manuscript is to provide a bibliometric analysis of the use of disc arthroplasty in scientific literature and highlight the main contributing authors and their publication characteristics. METHODS: The Scopus database was used to perform a title-specific, keyword-based search for all publications until June 2022. The keyword “total disc arthroplasty” was used. The most-cited 100 articles were selected for analysis. Parameters included the following: title, citation count, citations per year, authors, specialty first author, institution, country of origin, publishing journal, Source Normalized, Impact Per Paper (SNIP), and Hirsch index. RESULTS: Our search on disc arthroplasty yielded 580 articles that were published, with the first publication on the topic found in 1966. The most cited 100 articles received a total of 8694 citations, with an average of 86.94 citations per article. After assessing countries with the greatest contributions, United States, China, and Germany were top 3 with 54, 14, and 7 articles, respectively. CONCLUSION: The bibliometric analysis provides an overview of how medical research is analyzed in academic medicine. In the present study, we evaluated the global trends in disc arthroplasty for the treatment of degenerative disc disease.
