The Top 100 Cited Articles in Osteonecrosis of the Femoral Head: a Bibliometric Analysis

Background: The number of articles of clinical and basic research for osteonecrosis of the femoral head (ONFH) is increasing, to our knowledge, there is still a lack of bibliometric analysis on ONFH articles. The purpose of this study was to identify the top 100 cited (T100) articles related to ONFH research and analyze the characteristics and qualities of these articles. Methods: The T100 articles on ONFH were retrieved from the Web of Science database. The information about each article including citations, titles, authors, journals, countries, institutions, and keywords, was recorded for bibliometric analysis. Results: The T100 articles related to ONFH were mainly published from 1991 to 2010 (n=70), and originated from 24 countries. The USA, China, and Japan were the most productive countries in this regard. The most prolific institution was the University of Pennsylvania from the USA with 6 publications and 742 citations. The most-cited article was published in 1995 by Professor Steinberg ME. The five most frequently occurring keywords were “femoral head”, “osteonecrosis”, “core decompression”, “total hip arthroplasty” and “follow up”. The keywords like "bone tissue engineering" and "extracorporeal shock wave" have emerged in recent years. Conclusions: The USA, China, and Japan contributed greatly in terms of the T100 articles. The outcomes of core decompression and total hip arthroplasty gathered most research interests. In recent years, bone tissue engineering and extracorporeal shock wave have become new trends. However, the mechanism of ONFH is still unclear.
