HIP INTERNATIONAL publishes only peer-reviewed contributions, dealing with conservative hip surgery, traumatology of the hip, prosthetic surgery, biomechanics, and basic sciences relating to the hip in the following categories:

Original articles
Previously unpublished manuscripts describing clinical investigations, clinical observations, relevant clinical laboratory investigations. An original article should consist of around 16-18 double spaced, typewritten pages, corresponding to 6-8 printed pages. The text of articles must be divided into sections with the headings Introduction, Methods, Results and Discussion

Reviews
Containing the current state of knowledge or practice, integrating recent advances with accepted principles and practice, or summarizing and analysing consensus view of controversial issues in knowledge of practice.

Clinical cases
Clinical case descriptions are accepted in a limited number. They should be typed double-spaced and be 2-4 printed pages in length including references and 2 figures. Please refer to "Manuscript Guidelines". No more than three figures may be used. Authors share in the cost of colour figure reproduction as specified under "Figures".

Editorials
The aim of the editorials is to provide the reader with an overview of a particular subject. The length of an editorial should be limited to 6 printed pages including tables, figures, legends and references.

Letters to the Editor
Letters are welcome and will be considered for publication by two members of the editorial board, space permitting. The text should be limited to 500 words, 5 references and 1 figure.

Manuscripts will be reviewed for possible publication with the understanding that they are being submitted only to Hip International and have not been published, simultaneously submitted, or already accepted for publication elsewhere. This does not preclude consideration of a manuscript that has been rejected by another journal or of a complete report that follows publication of preliminary findings elsewhere, usually in the form of an abstract. Copies of any possibly duplicative published material should be submitted with the manuscript that is being sent for consideration. Hip International will not consider manuscripts that have appeared, in part or in total, in other publications. The Editors reserve the right to make corrections in grammar and style.

With the acceptance of the manuscript for publication the Publisher acquires full and exclusive copyright for all languages and countries. It is the corresponding author's responsibility to complete and sign, on behalf of all authors, the Copyright Transfer Form and send it together with the initial submission.  Authors grant the copyright holder full and exclusive copyright for all languages and countries on the manuscript in return for which they can re-use their papers in their future printed work, with the understanding that full acknowledgement will be given to the manuscript published in Hip International.

 

MANUSCRIPT GUIDELINES
Manuscripts should be accompanied by a cover letter from the corresponding author. The cover letter should contain a statement that the manuscript has been seen and approved by all authors and should supply any additional information that may be helpful to the Editors, such as the type of article the manuscript represents in the particular journal, information on publication of any part of the manuscript, and whether the author(s) will be willing to meet the cost of reproducing colour illustrations. Include copies of any permissions needed to reproduce published material or to use illustrations of identifiable subjects. All manuscripts will be read by the Editor(s) and reviewed further by two reviewers. Form and contents should be very carefully checked to exclude the need for later corrections. The size of the manuscript, including tables, illustrations, references and acknowledgements should be limited to six (6) printed pages corresponding to between 16-20 double spaced typewritten pages. Additional pages will be charged Euro 130,00 each directly by the Publisher and notified to the corresponding author with the proofs. Extra page charges do not apply to invited articles. Members of the European Hip Society and of the affiliated societies (SECCA, ACARO, SIA, TOTBID) will be charged the reduced fee of Euro 100,00. Type manuscript, preferably using Arial font size 12, double spaced on A4 size paper and number pages consecutively in the top right corner of each page, beginning with the title page. Begin each of the following sections on separate pages: Title page, Abstract and Keywords, Text, Acknowledgements, References, Tables, Figures, Legends.

Title page
The title page should contain:

- Manuscripts reporting the results of experimental investigation on human subjects must include a statement to the effect that informed consent was obtained. If the study being reported involved human subjects, human derived materials, or human medical records, please include one of the following statements in the Materials/ Patients and Methods section:
* Institutional Review Board (IRB)/Ethics Committee approval was obtained.
* IRB/Ethics Committee decided approval was not required for this study.
- Conflict of interest. All manuscripts must state, in a footnote, whether any authors have proprietary interest or not.

Abbreviations
Use only standard abbreviations. The full term for which an abbreviation stands for should precede its first use in the text unless it is a standard unit of measurement.

Abstract and key words
The second page should carry an abstract of no more than 200-250 words. The abstract should state the purposes of the study or investigation, basic procedures, main findings and the principal conclusions.
Key words: provide and identify 3 to 6 key words Use terms from the Medical Subject Headings list from lndex Medicus whenever possible.

Text
The text of original, observational and experimental articles must be divided into sections with the headings lntroduction, Materials and Methods, Results, and Discussion. Long articles may need subheadings within some sections to clarify their contents, especially the Results and Discussion sections. Other types of articles such as reviews, case reports and editorials are likely to need other formats.
Introduction
Clearly state the purpose of the article. Summarize the rationale for the study or observation. Give only strictly pertinent references, and do not review the subject extensively.
Materials and Methods
Describe your selection of the observational or experimental subjects (patients or experimental animals, including controls) clearly. Identify the methods, apparatus (manufacturer's name and address in parenthesis), and procedures in sufficient detail to allow other workers to reproduce the results. Give references to established methods, including statistical methods; provide references and brief descriptions of methods that have been published but are not well known; describe new or substantially modified methods, give reasons for using them, and evaluate their limitations. When reporting experiments on human subjects, indicate whether the procedures followed were in accord with the ethical standards of the committee on human experimentation of the institution in which the experiments were done or in accord with the Helsinki Declaration of 1975. When reporting experiments on animal subjects, indicate whether the institutions or the national research councils guide for the care and use of laboratory animals was followed. Identify precisely all drugs and chemicals used, including generic name(s), dosage(s), and route(s) of administration. Do not use patients name, initials, or hospital numbers.
Include numbers of observations and the statistical significance of the findings when appropriate. Detailed statistical analyses, mathematical derivations, and the like may sometimes be suitably presented in the form of one or more appendixes.
Results
Present your results in logical sequence in the text, tables, and illustrations. Do not repeat in the text all the data in the tables or illustrations, or both: emphasize or summarize only important observations.
Discussion
Emphasize the new and important aspects of the study and conclusions that follow from them. Do not repeat in detail data given in the Results section. Include the implications of the findings and their limitations and relate the observations to other relevant studies. Link the conclusions with the goals of the study but avoid unqualified statements and conclusions not completely supported by your data. Avoid claiming priority and alluding to work that has not been completed. State new hypotheses when warranted, but clearly label them as such. Recommendations, when appropriate, may be included.

Acknowledgements
Acknowledge statistical consultation and assistance (when provided by a person different from the author) in an acknowledgement at the end of the article before the references. Indicate the name, degree and affiliation of the individual. For all others assisting in the preparation of a manuscript acknowledgements cannot be done, however valuable their service. Authors are responsible for obtaining written permission from everyone acknowledged by name because readers may infer their endorsement of the data and conclusions.

References
References should follow text and begin on a separate page. They must be double-spaced and numbered consecutively in order of appearance in the text. Switch off any automated reference numbering tool, if in use. Identify references in text, tables, and legends by Arabic numerals (in parentheses). References cited only in tables or in legends to figures should be numbered in accordance with a sequence established by the first identification in the text of the particular table or illustration. The titles of journals should be abbreviated according to Index Medicus/Medline. If there is any doubt about abbreviation of a journal name, it should be spelled out completely. All references must be verified by the author(s) against the original documents. You may use the reference checking tool available at www.ncbi.nlm.nih.gov/entrez/query/static/citmatch.html.
Cite only published studies as references. Any references (including books or articles) that have been accepted for publication, but not yet published, should have the term "in press" in the reference in place of volume and page numbers. These must be updated prior to publication, if possible. You may also acknowledge "unpublished data" or "submitted" articles within parentheses in the text. For abstracts, oral or poster presentations follow the same rules as for unpublished materials. Examples of correct forms of references:

Tables
As a general rule, tables should not unnecessarily offer duplicate information given in the text. Type each table on a separate sheet, using double spacing. Tables should be created in a Word document using the table tools. Do not format tables as columns or tabs and do not submit tables as figures. Tables should be numbered consecutively in Roman numerals by order of citation in the text. Each table must include title, appropriate column heads and explanatory legends, including definitions of any abbreviation used. For footnotes, use the following symbols in this sequences: *, †, ‡, §, ||, , **, †† ... Identify statistical measures of variations such as SD and SEM.

Figures
No text should appear on the face of a figure. Lettering, arrows, and other symbols should be large enough to remain legible after reduction to a figure with a base of 10 cm. All symbols or letters that appear on the figures should be defined in the legend. Arial font should be used for any lettering or text on a figure. If possible use the same font type and size in all artworks (we recommend Arial 12). When a patient is identifiable in a photograph, the author or authors must supply the Journal with evidence of the patient's permission to publish the photograph. If a figure has been published elsewhere, acknowledge the original source and submit written permission from the copyright holder to reproduce the material. Permission is required, regardless of authorship or publisher, except for documents in the public domain. Do not embed figures in a Word file and do not submit Powerpoint (PPT) figures. Always submit each figure as a separate file.

The Publisher charges authors directly for colour figures included in their manuscript. Colour figure charge is Euro 600,00 as start up fee plus Euro 80,00 for each additional figure. Authors will receive a colour charge form from the Publisher together with the galley proofs, to be signed prior to publication and will be invoiced after publication in print of the manuscript.

Colour illustrations, graphs and figures
Create and save your artwork as CMYK, as it provides a better print copy for publishing, in TIFF, EPS or JPG format with a resolution of at least 300 dpi. To ensure the best printing results any figure containing text should be saved only as TIFF file.

Black and white illustrations, graphs and figures
Save your file converting it from the software used to create it setting the colour mode as greyscale and saving it as TIFF format with a resolution of at least 600 dpi if text is included. If no text is included, set the resolution at a minimum of 300 dpi.

Legends
Type legends for illustrations double spaced, starting on a separate page with Arabic numerals corresponding to the illustrations. When symbols, arrows, numbers, or letters are used to identify parts of the illustrations, identify and explain each one clearly in the legend. Explain internal scale and identify method of staining in photomicrographs.

MANUSCRIPT SUBMISSION
