Scope and Policy

The journal Acta Ortopédica Brasileira, official organ of the Department of Orthopedics and Traumatology, Faculdade de Medicina da Universidade de Sâo Paulo (DOT/FMUSP), operates under a continuous publication model of bi-monthly issues (Jan/Feb, Mar/Apr, May/Jun, Jul/Aug, Sep/Oct, and Nov/Dec) with an English version. The titles, abstracts and keywords are published in English and Portuguese.The publication follows entirely the international standard of the International Committee of Medical Journal Editors (ICMJE) - Vancouver Convention - and its uniform requirements []. Submitted papers are sent for peer review evaluation to decide whether they should be published or not, suggesting improvements, asking the authors for clarification and making recommendations to the Editor-in-Chief. The editor(s) and/or reviewer(s) responsible for approval of the manuscript will be identified in the accepted articles. The concepts and statements contained in the papers are the sole responsibility of the authors.

We ask authors to observe the following instructions for publication.

Publication fee

To allow for the sustainability and continuity of the Acta Ortopédica Brasileira, we inform authors that starting in January 2017 a publication fee was instituted for articles. Authors are responsible for paying a fee to publish accepted articles, which will be charged to authors when their respective works are approved. Following the acceptance of the manuscript and notification by the editor-in-chief, authors should make a deposit in the name of the Atha Mais Editora LTDA, CNPJ14.575.980/0001-65, Santander (033) Bank agency 4337, account number 13001765-6. A copy of the deposit receipt should be sent to the email  and include the work protocol number (AOB-0000), the article title, and the name of the article’s author(s). 

The fee is a R$ 1.150,00 (US$ 600). Upon submitting the manuscript and filling out the registration form, the author should read and agree to the terms of original authorship, relevance, and quality, as well as to the charging of the fee. Upon indicating agreement with these terms, the manuscript will be registered on the system for evaluation.


Articles format

Number of words recommended according to the publication type: The criteria specified below should be observed for each type of publication. The electronic counting of words should start at the Introduction and end at the Conclusion.


MANUSCRIPT PREPARATION: The journal Acta Ortopédica Brasileira receives the following types of contributions: Original Article, Update Article and Review Article. The Update and Review articles are only considered by invitation from the Editorial Board.
Manuscripts should be sent in .txt or .doc files, double-spaced, with wide margins. Articles should be submitted ideally in English and Portuguese. Measures should be expressed in the International System (Système International, SI), available at  and standard units, where applicable.
It is recommended that authors do not use abbreviations in the title and limit their use in the abstract and in the text.
This journal adopts Writecheck plagiarism detection system, however all published content  are the sole responsibility of the authors.
The generic names should be used for all drugs. The drugs can be referred to by their trade name, however, the manufacturer’s name, city and country or electronic address should be stated in brackets in the Materials and Methods section.

PRESENTATION LETTER: The cover letter accompanying the submission of the manuscript should be signed by the corresponding author and should include the following information: Title, names of all authors, text authorizing the publication of the article, stating that it has not being submitted simultaneously elsewhere and it has not been previously published (publication in another language is considered as the same article). Authors should make sure that the manuscript is entirely in accordance with the instructions.

Preprint: The Acta accepts the submission of articles published as preprints. A preprint is a completed scientific manuscript that is deposited by the authors in a public server. It may have been previously published without having passed through a peer review and can be viewed free of charge by anyone in the world on platforms developed today for this purpose, such as the Scielo PrePrint platform ( 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 journal publications (validated through peer review) function in parallel as a communication system for scientific research.1,2

Data sharing: The Acta encourages the sharing, citation and referencing of all data, program code and content underlying article texts in order to facilitate the evaluation of research, the reproducibility of studies, and the preservation and reuse of content. Data sharing can 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 list of references in accordance with the Vancouver Style standards.3


ABBREVIATIONS: The use of abbreviations should be minimized. Abbreviations should be defined at the time of its first appearance in the abstract and also in the text. Non-standard abbreviations shall not be used, unless they appear at least three times in the text.
Measurement units (3 ml or 3 mL, but not 3 milliliters) or standard scientific symbols (chemical elements, for example, Na, and not sodium) are not considered abbreviations and, therefore, should not be defined. Authors should abbreviate long names of chemical substances and therapeutic combinations terms. Abbreviations in figures and tables can be used for space reasons, but should be defined in the legend, even if they were defined in the article.


CLINICAL TRIALS: The journal Acta Ortopédica Brasileira supports the Clinical Trials Registry policy of the World Health Organization (WHO) and the ICMJE, recognizing the importance of these initiatives for the registration and international dissemination of clinical studies in open access. Therefore, it will only accept for publication articles involving clinical research that have received an identification number in one of the clinical trials registry platforms validated by WHO and ICMJE. The URLs of these registry platforms are available at the ICMJE page [].


CONFLICT OF INTERESTS: As recommended by the ICMJE and resolution of the Brazilian Federal Council of Medicine nº 1595/2000, authors have the responsibility to recognize and declare any potential financial conflicts of interest, as well as conflicts of other nature (commercial, personal, political, etc.) involved in developing the work submitted for publication.

CORRECTION OF PROOFS: As soon as they are ready, proofs in electronic format shall be sent via email to the author responsible for the article. Authors must return the proof with the appropriate corrections via email no later than 48 hours after having received them. The remittance and return of the proofs by electronic mail is intended to speed up the revision process and subsequent publication of these documents.


ELECTRONIC FILE ORGANIZATION: All parts of the manuscript must be included in a single file. This file must be organized to contain a cover page first, then the text and references followed by figures (with captions) and, at the end, tables and charts (with captions).
