To determine characteristics of Latin American (LA) productivity in spine surgery published worldwide between 2004 and 2021 compared between periods and global literature.
A comprehensive search about LA productivity in the field of spine surgery using the Scopus and PubMed databases was performed in February 2022. The results were limited to articles published in indexed journals from 2004 to 2021.
A total of 1447 publications were identified in the study period. The number of publications has increased across evaluated decades, with 583 between 2004 and 2013 (58.3/year) and 864 between 2014 and 2021 (108/year), and a yearly increase was demonstrated (P = 0.0001). Comparing the most productive year in the first (2012) and last decade (2020), a 1.79-fold increase was demonstrated. Brazil ranked first in productivity (51.14%), followed by Mexico (26.40%) and Argentina (8.64%). Coluna/Columna published the largest number, with 309 articles (21.35%). The top 10 institutions published at least 475 (32.82%) and the most productive was the University of Campinas (Brazil, 74).
This scientometric study is one of the first regional evaluations worldwide. The number of publications in the spine surgery field in Latin America has continued to increase over evaluated decades from 58.3 per year to 108, and a 1.79-fold increase between the most productive years for each decade. Brazil is still the greatest contributor (51.14%), with Mexico (26.40%) and Argentina (8.64%) as growing contributor countries. Most publications were classified as Level of Evidence 4, and this result reflects the importance of continuous research development in the quality of research for our region.
比较 2004 年至 2021 年期间和全球文献中拉丁美洲（LA）脊柱外科发表的论文的特点。
2022 年 2 月，使用 Scopus 和 PubMed 数据库对脊柱外科领域的 LA 生产力进行了全面检索。结果仅限于 2004 年至 2021 年发表在索引期刊上的文章。
研究期间共确定了 1447 篇出版物。发表的文章数量在评估的几十年中有所增加，2004 年至 2013 年为 583 篇（每年 58.3 篇），2014 年至 2021 年为 864 篇（每年 108 篇），并显示出每年都在增加（P=0.0001）。与第一个十年（2012 年）和最后一个十年（2020 年）中最具生产力的年份相比，显示出 1.79 倍的增长。巴西在生产力方面排名第一（51.14%），其次是墨西哥（26.40%）和阿根廷（8.64%）。Coluna/Columna 发表的文章数量最多，有 309 篇（21.35%）。排名前 10 的机构至少发表了 475 篇论文（32.82%），生产力最高的是坎皮纳斯大学（巴西，74 篇）。
这是一项全球性的首个区域性评价的科学计量研究。在评估的几十年中，拉丁美洲脊柱外科领域的出版物数量从每年 58.3 篇增加到每年 108 篇，每个十年最具生产力的年份增加了 1.79 倍。巴西仍然是最大的贡献者（51.14%），墨西哥（26.40%）和阿根廷（8.64%）是增长的贡献者。大多数出版物被归类为证据水平 4，这一结果反映了我们地区不断发展研究，提高研究质量的重要性。
