Minerva Ortopedica e Traumatologica publishes scientific papers on orthopedics and traumatology. Manuscripts may be submitted in the form of editorials, original articles, review articles, case reports, special articles, letters to the Editor and guidelines. The journal aims to provide its readers with papers of the highest quality and impact through a process of careful peer review and editorial work. Duties and responsibilities of all the subjects involved in the editorial process are summarized at Publication ethics. Manuscripts are expected to comply with the instructions to authors which conform to the Uniform Requirements for Manuscripts Submitted to Biomedical Editors by the International International Committee of Medical Journal Editors (ICMJE).
Submission of manuscripts
Papers should be submitted directly to the online Editorial Office at the Edizioni Minerva Medica website: The journal does not apply any charges for online submission. Authors are requested to choose a corresponding author. The corresponding author is responsible for the following requirements: managing all communications between the journal and all co-authors during the manuscript submission, peer review, publication process and after publication; ensuring that the names of authors, their arrangement and affiliations are correct; ensuring that all listed authors have approved the manuscript before submission; making sure all permissions to reproduce previously published material have been obtained from the copyright owner; making sure disclosures, declarations, statements from all authors are included in the manuscript as appropriate. Although for technical and organizational reasons the corresponding author has primary responsibility for correspondence with the journal, copies of the most significant correspondence will be sent to all listed authors.
Authors are welcome to suggest 2-3 suitable reviewers when they submit their manuscript by providing in the covering letter their names, institutions and e-mail addresses. When suggesting reviewers, authors should make sure they have a high degree of expertise and independence in the field of the study presented. Please note that suggestions are welcome and may help facilitate the peer-review process but the journal cannot guarantee to use them.
Submission of the manuscript means that the paper is original and has not yet been totally or partially published, is not currently under evaluation elsewhere for simultaneous consideration, is free of plagiarism and does not infringe any copyright or right of privacy. If accepted, the manuscript will not be published elsewhere either wholly or in part in any form or language except in case of specific agreements. All authors are responsible for their research. The manuscript must be approved by all co-authors, if any, as well as, tacitly or explicitly, by the responsible authorities of the institution where the work was carried out. Specific discipline rules should be followed by authors for acquiring, selecting and processing data. Results should be presented clearly, honestly and without fabrication or inappropriate data manipulation.
Duplicate or multiple publication
Splitting the data concerning one study in more than one publication could be acceptable if authors justify the choice with good reasons both in the cover letter and in the manuscript. Authors should state what new scientific contribution is contained in their manuscript compared to any previously published article derived from the same study. Relevant previously published articles should be included in the cover letter of the currently submitted article. All submissions are subject to review with iThenticate plagiarism detection software.
Permissions to reproduce previously published material
Material (such as figures) taken from other publications must be accompanied in the cover letter by permission of the copyright owner for both print and online format with complete reference information (for example, a footnote at the bottom of the figure must credit the original source). Any material received without such permission will be assumed to have been originally created by the authors.
Statement of human rights
All articles reporting studies that involve human subjects must include a statement at the beginning of methods section, clearly indicating that the study has been approved by the institutional research ethics committee before experiment was started and that has been conducted in accordance with the principles set forth in the Helsinki Declaration. This paragraph must contain the following information: the identification details of the ethics committee; the name of the chairperson of the ethics committee; the protocol number that was attributed by the ethics committee and the date of approval by the ethics committee.
Patient consent
Authors should include at the beginning of the methods section of their manuscript a statement clearly indicating that patients have given their informed consent for participation in the research study.
Every precaution must be taken to protect the privacy of patients. Authors should obtain permission from the patients for the publication of photographs or other material that might identify them. If necessary, a copy of such permission may be requested.
Statement on welfare of animals
When reporting experiments on animals, authors should include a statement at the beginning of the methods section indicating that the study was approved by the institutional research ethics committee and specifying the guidelines for care of animals that have been followed.
Conflicts of interest
A conflict of interest occurs when any financial interest may affect the content of an article. This does not imply that any financial involvement with a sponsor that supported the research or funded a consultation is problematic.
To promote transparency and avoid any possible bias of the readers towards the article, each author must disclose any potential conflict of interest both in the Journal Article Publishing Agreement Form and at the end of the manuscript file in the notes under the “Conflicts of interest” section. Potential conflicts of interest can be directly or indirectly related to an article and may include but are not limited to research funds from organizations that have financial interest in the results of publication, financial support for attending symposia or educational programs, consultant relationships, employment funds, personal financial interests. The conflict of interest disclosure should follow the recommendations of the ICMJE. If there is no conflict of interest, the authors should state at the end of the manuscript file in the notes under the “Conflicts of interest” section: “The authors certify that there is no conflict of interest with any financial organization regarding the material discussed in the manuscript”.
All sources of funding should be acknowledged at the end of the manuscript file in the notes under the “Funding” section. The role of the sponsor, if any, in the study design, in the acquisition analysis and interpretation of data, in drafting the manuscript should be briefly described. If the sponsor has not been specifically involved in the research this should be stated.
Authorship and contributorship
Authors and contributors must meet the criteria for authorship and contributorship established by the ICMJE. The ICMJE recommends that authorship be based on all the following 4 criteria: 1) substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; 2) drafting the work or revising it critically for important intellectual content; 3) final approval of the version to be published; 4) agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved. All persons (individual authors) and organizations (collective authors) that meet the 4 criteria of the ICMJE for authorship must be listed in the byline of the article. Individual authors that are part of a collective author can be listed at the end of the manuscript in the Notes under the “Group Name” section. All persons that meet fewer than all 4 of the above criteria for authorship should not be listed as authors, but they should be acknowledged as contributors at the end of the manuscript in the Notes under the “Acknowledgements” section.
Authors must specify the contribution of each person that has participated to the study at the end of the manuscript file in the notes under the “Authors' contribution” section. Full approval of the manuscript by all authors should be explicitly stated by including the following statement “All authors read and approved the final version of the manuscript”.
Changes of authorship
Addition, deletion or rearrangement of authors' names in the byline after manuscript submission must be sent to the journal Manager by the corresponding author and must include the reason why the author's name should be added or removed or rearranged, written confirmation from all authors that they agree with the addition, removal or rearrangement, written confirmation from the author that has been added that he/she meets the criteria for authorship. In case of addition or removal of authors this include confirmation from the author being added or removed. Requests will be taken into consideration only if received from the corresponding author. After online publication of the manuscript it is not generally permitted to add, remove or rearrange authors. In case this is exceptionally allowed, the same procedure will be followed and an erratum will be published.
The journal will not be in a position to investigate in case of an authorship issue before or after publication and will therefore raise this issue with the responsible authorities of the institution where the work was carried out. In any case, the journal will abide by the Committee on Publication Ethics (COPE) guidelines and reserves the right to withdraw the manuscript.
Data availability
To promote transparency of data supporting the results reported in the article, the journal encourages authors to provide a statement of data availability, provided that the research data can be made publicly. This should be included at the end of the “Materials and Methods” section under a separate “Data availability” subheading. Data availability statement should include information on where data can be found, whether data are deposited on publicly available data research repositories or they are available on reasonable request from the corresponding author (examples of data availability statements: 1) the data associated with the paper are available in the [NAME] repository; 2) the data associated with the paper are not publicly available but are available from the corresponding author on reasonable request; 3) the data associated with the paper will be available in the [NAME] repository following an embargo period). Such data will not be published as Supplementary Digital Material.
Fundamental errors
Any significant error must be brought to the journal attention by the authors. Depending on the nature of the error, the journal will decide whether to publish a correction or a retraction.
Potential misconduct
Examples of inappropriate acts include but are not limited to fabrication, falsification, plagiarism, repetitive publication, obfuscation of significant research results, violating requirements for experimentation with human subjects or animals, failing to comply with authorship requirements, failing to report significant conflicts of interest.
In case of a suspicion of misbehavior or alleged fraud, the journal will follow the COPE guidelines. If deemed necessary, the publisher will take one of the following actions including but not limited to: rejection if the manuscript is still under evaluation, publication of an erratum, a retraction if the article has already been published online. In case of erratum or retraction, the article will be maintained on the journal site and in the abstracting and indexing services as corrected or retracted and the reason will be given in the published erratum or retraction note.
Journal Article Publishing Agreement
Papers must be accompanied by the Journal Article Publishing Agreement relative to copyright, permitted uses, originality, authorship and author contribution, institutional research ethics committee approval, patient consent, data availability and conflicts of interest, signed by the corresponding author on behalf of all authors.
Article sharing
The authors of articles published in Minerva Medica journals are permitted to self-archive the preprint and postprint version of their research in several ways provided that they comply to the guidelines on Article sharing about what can be archived, where and when.
The Publisher, Editors, and Editorial Board cannot be held responsible for the opinions and contents of publications contained in this journal.
The authors implicitly agree to their paper being peer-reviewed. All manuscripts will be reviewed by Editorial Board members who reserve the right to reject the manuscript without entering the review process in the case that the topic, the contents, the format or ethical aspects are inappropriate. In order to ensure accuracy and transparency, every step of the peer review process is fully documented and recorded. If modifications to the manuscript are requested, the corresponding author should send to the online Editorial Office the revised manuscript under two separate files, one file containing the revised clean version and another containing both a letter with point-by-point responses to the reviewers' comments and the revised version with corrections highlighted. Once accepted, all manuscripts are subjected to copyediting and formatting. The authors will be informed by e-mail when proofs are made available online. Other than the proofs, they will also find for consultation only the highlighted manuscript with the changes made by the copyeditor. Correction of proofs should be limited to typographical errors. Substantial changes in content (changes of title and authorship, new results and corrected values, changes in figures and tables) are subject to editorial review. Changes that do not conform to the journal's style are not accepted. Corrected proofs must be sent back within 3 working days to the online Editorial Office of the journal. In case of delay, the editorial staff of the journal may correct the proofs on the basis of the original manuscript and forward the article to publication.
Publication of manuscripts is free of charge. Figures supplied in color will be published in color online free of charge. For color reproduction in the printed version, authors will receive upon request information regarding the costs. Linguistic revision, and excessive alterations to proofs will be charged to the authors. Authors will receive instructions on how to order reprints and a copy of the manuscript in PDF.
