Bibliometric Analysis of the 100 Most Cited Articles on Intervertebral Disk Research: From 1900 to 2017 Year.

STUDY DESIGN

A bibliometric review of the literature.

OBJECT

To analyze and quantify the most frequently cited papers in intervertebral disk research.

SUMMARY OF BACKGROUND DATA

The number of citations that a paper has received reflects its impact in related research area. In the field of disk research, however, it remains unknown which papers are most cited. By searching related literature databases, we identified the most cited 100 articles that advanced the understanding of the intervertebral disk to provide a historic view of scientific research of the disk.

MATERIALS AND METHODS

Intervertebral disk original research-related publications from January 1, 1900 to December 31, 2017 were retrieved from the Web of Science database. Each retrieved article was analyzed using the Cited Reference Search tool to identify the most cited articles. The number of citations, year of publication, publishing journal, authorship, country of publication, and the knowledge maps of keywords were gathered and generated.

RESULTS

The number of citations of the 100 selected articles ranges from 209 to 1269, and they were published from 1953 to 2009. Basic research is the most common type of study (n=60), followed by epidemiological study (n=40). Spine published 57 of the most cited 100 papers. The greatest contribution came from the United States of America (n=41), followed by the United Kingdom (n=18) and Japan (n=9). Frequently appearing keywords classified into 3 clusters: "biological study," "clinical study," and "imageological study." The keyword "degeneration" was mentioned the most, 51 items, and the word "development" was the latest hot spot in the most cited articles.

CONCLUSIONS

In the field of disk research, some papers were heavily cited more than 100 times, suggesting these studies have substantially contributed to the body of knowledge of the intervertebral disk and findings were widely accepted by related clinicians and scientists.
