BackgroundAtlantoaxial spine surgery is a challenge to spinal surgeons because of its proximity to neurovascular structures. This study aimed to identify and analyze the scientific publications in atlantoaxial spine surgery from different countries and institutions.MethodsClarivate Analytics Web of Science was used to search all articles for information on atlantoaxial spine surgery. The annual research, countries, journals, authors, institutions, citation frequency, and journal metrics were extracted. These results from countries and hotspots (keywords in publications) were subjected to co-occurrence analysis using VOSviewer, after which the top 100 most-cited articles were analyzed further.ResultsA total of 3161 articles were included. A trend toward an increasing number of publications on atlantoaxial spine surgery in recent years was evident. Among all countries, the United States contributed the most publications. Seth Gordhandas Sundarda Medical College had the highest number of publications among institutions. Among all research categories, fixation and fusion were the most common areas discussed. The screw-rod system described in the most-cited article (cited 823 times) appeared to be the most popular fixation method. With the development of C1 and C2 screw technology, the screw-rod system is becoming increasingly popular.ConclusionsThe atlantoaxial spine surgery literature has grown continuously in recent years. The United States is the largest contributor in this field. Fixation and fusion are the most common areas, and fixation-related studies should be closely followed. The screw-rod fixation system is becoming increasingly popular.Copyright © 2020 Elsevier Inc. All rights reserved.
