Manuscript preparation

Peer Review

After the entire submission process, the editorial secretariat and preliminary analysis by the area editors (desk review), the articles may be sent for evaluation by the referees. The area editors together with the COLUNA/COLUMNA editorial board are mostly university professors, which allows for a thorough and rigorous peer review. 


Following approval by the area editors, the evaluation process continues with all manuscripts being analyzed by two or more reviewers. Articles that do not have merit and do not fit the editorial policies of the journal will be rejected with no recourse. Reviewer comments will be returned to the authors for text changes or justification for maintaining it. Following reviewer approval, the articles will be forwarded to the associated editors for final approval.

Articles accepted for publication may undergo editorial revisions to facilitate their clarity and understanding without, however, changing the content. 

Review process and additional information 


  • All scientific contributions are submitted to the following analysis flow: Editorial Secretariat → Editor-in-Chief → Area Editors and Editorial Board Evaluators.
  • All works sent to COLUNA/COLUMNA will be subjected to initial evaluation by the area editors (desk review), who will decide whether or not to send them for peer review.
  • Only articles that are in strict compliance with the specified standards and contain all the required supplementary documents will be forwarded to the reviewers. 
  • If the submission of the documents is incomplete, the article will be archived.  
  • The authors have 30 days from the communication receipt date to make the changes requested by the reviewers. Failure to meet this deadline will result in the withdrawal of the article from the review process.
  • Extensive or substantial changes will not be accepted after an article has been accepted for publication or during final proof of the article.
  • Communications will be conducted exclusively by messages via the e-mail system. 
  • Requests sent by COLUNA/COLUMNA prior to the approval of an article must be made through the SciELO Submission System. After article approval they must be sent via e-mail ( and no longer through the SciELO Submission System. 
  • The subject referenced in the e-mail should not be changed and questions not relevant to the subject cited should be sent in another communication with an appropriate subject and the article identification number.
  • The final laid out versions (Portuguese, English, and Spanish) will be sent to the author, who must return them within 48 hours with only minimal changes. If the author does not respond within this timeframe, these will be considered the final versions for publication and no further changes will be possible.



The COLUNA/COLUMNA journal accepts Preprints.

A Preprint is a completed scientific manuscript that is posted to a platform by the authors. This is published after being accepted by COLUNA/COLUMNA on the SciELO Preprint platform ( A Preprint can be viewed for free, allowing scientists to have direct control of disseminating their work to the global scientific community. In most cases, a work published as a Preprint is also submitted to a journal for peer review. Thus, Preprints (not validated through peer review) and publication by journals (validated through peer review) function in parallel as a communication system for scientific research. 
Posting a manuscript to more than one Preprint platform is not considered duplicate publication.

Starting in 2021, we will accept Preprints and the use of open science platforms as a way to encourage communication among authors.

Data sharing

The COLUNA/COLUMNA journal encourages the sharing, quoting, and referencing of all data, program codes and other content underlying the text of articles in order to facilitate the evaluation of research, the replicability of studies, and the preservation and reuse of content. Data sharing must be published on the SciELO Dataverse platform (

Citations should facilitate access to research content and when articles, books, and online publications are cited, the data should be cited in an appropriate place in the text and the source included in the reference list in accordance with the Vancouver Style standards. If there is an access link, it should be included. The author responsible for the submission must inform if the manuscript cites data, program codes and other materials underlying the articles. If so, the respective URLs must be informed; otherwise the author must offer a justification. Therefore, COLUNA/COLUMNA recommends the use of the Open Science Conformity Form available at the time of submission. This form will help ensure that the research data is an integral part of the submitted work and it must be submitted as a supplementary file to the manuscript and be accessible to the reviewers.

The article must contain the following items: Structured Abstract, Keywords, Introduction, Materials and Methods, Results, Discussion and Conclusions.


Review articles: The editor usually requests review articles from authors with proven experience in the areas of Basic Sciences, the Spine, Spinal Pathologies, Orthopedics and Traumatology, Rehabilitation, Degeneration, Tumors/Infection, Minimally Invasive Surgery, among others. These express the author’s experience and should not only reflect a review of the literature. Review articles should address specific topics in order to update readers on topics, issues, or specific questions. The editorial board will evaluate the quality of the article, the relevance of the chosen theme, and the proven distinction of the authors in the specific area addressed. Inadequacy in any of the above items will result in the editors’ rejection of the article without being submitted to a peer review.

Technical Note: Intended for the disclosure of diagnostic method or experimental surgical technique, new surgical instruments, orthopedic implants. Must have: Title; unstructured abstract; Keywords; Explanatory Introduction, , Material and Methods or Technique Description, Final Comments and References.

Systematic review/update/meta-analysis: COLUNA/COLUMNA encourages authors to submit systematic literature review articles in the areas of Basic Sciences, the Spine, Spinal Pathologies, Orthopedics and Traumatology, Rehabilitation, Degeneration, Tumors/Infection, Minimally Invasive Surgery, among others. The editorial board will evaluate the quality of the article, the relevance of the chosen theme, the bibliographical research procedure, the article inclusion criteria, and the statistical treatment used. Inadequacy in any of the above items will result in the editors’ rejection of the article without being submitted to a peer review.
Case report: Specific clinical cases that provide relevant and illustrative information about the diagnosis and treatment of a particular case that is rare in Sports and Exercise Medicine. The articles must be objective and precise, containing the following items: abstract, introduction, objective report containing the case history, the physical examination and the complementary examination findings, as well as the treatment and follow-up; a discussion explaining in detail the clinical implications of the case in question and comparing it with data from the literature, including similar cases reported there; and bibliographical references.
