About the journal
Acta Orthopaedica (previously Acta Orthopaedica Scandinavica) presents original articles of basic research interest, as well as clinical studies in the field of orthopedics and related sub disciplines. Ever since the journal was founded in 1930, by a group of Scandinavian orthopedic surgeons, the journal has been published for an international audience. Acta is distributed by Taylor & Francis.
Acta Orthopaedica publishes original papers from all parts of the world. Articles requiring extensive space, such as monographs, doctoral theses and congress transactions, are published as supplements. Over the years, Acta Orthopaedica has issued more than 300 supplements.
Instructions to Authors
Submission of manuscripts
Manuscripts should be submitted online, www.actaorthopscand.org. Authors are encouraged to provide the names, addresses, and e-mail of potential reviewers. Note the following points:
a. The manuscript should be prepared according to Uniform Requirements for Manuscripts submitted to Biomedical Journals (www.icmje.org). American spelling is preferred.
b. Authors submitting a paper do so on the understanding that it has not been published and is not being considered for publication elsewhere. The authors should provide a statement about previous submissions and reports that might be regarded as duplicate publication of the same or a similar paper. Copies of that study should be submitted with the paper.
c. Authors should provide a description of their individual contributions to the study.
d. Reports of randomized controlled trials should comply with the CONSORT statement (www.consort-statement.org).
e. The study protocol (e.g., the protocol approved by the ethics committee) and a completed CONSORT checklist and flowchart should be appended to the manuscript.
f. All clinical trials submitted for consideration should have been registered in a public trials registry.
g. Authors of systematic reviews and meta-analyses are advised to consult the consensus statements QUORUM and MOOSE for randomized trials and observational studies, respectively (see JAMA 2000; 283: 2008–12 and www.consort-statement.org/QUOROM.pdf).
h. All documents with original data of relevance to the submitted manuscript should be stored and be retrievable on request for a minimum of 10 years. Authors are encouraged to include a copy of raw data in electronic form and/or make these data available via the internet.
Manuscript layout
Title
The title should include information on the results of the investigation, including the number of patients, average follow-up, and animal or cadaver experiments. The first name, middle initial(s), and last name of each author should be given with department affiliations as well as the name, complete address and e-mail of the corresponding author.
Abstract
The abstract should not exceed 250 words. It should consist of 4 parts: Background and purpose, Patients/material/animals and methods, Results and Interpretation.
Introduction
The introduction should focus on the state of knowledge at the beginning of the study. The aims and main hypothesis of the study should be stated clearly. Only in exceptional cases should it exceed one typewritten page. Case reports. These should be short, include the Case history and Discussion without an Introduction.
Patients/material/animals and methods
The selection of subjects and the inclusion or exclusion criteria should be described. Subjects who declined to participate, withdrawals and those with incomplete follow-up should be accounted for. Describe in detail how the measurements were made and the techniques used.
Statistics
All statistical methods should be mentioned. Unusual methods should be referenced. The tests should be two-sided, unless the use of one-sided tests is justified. No data should be removed, imputed, weighted, adjusted or trimmed unless they are specifically described and justified and its consequences are given.
Hypothesis tests (p-values). These tests should be used, in combination with a defined effect size and when statistical power has been considered. Give p-values with real numbers, if these are greater than 0.001 (1 digit except zeros), otherwise use ‘p < 0.001’. Do not use ‘ns’, ‘p > 0.05’ or asterisks. In most instances, the 95% confidence intervals should be given, especially in exploratory analyses and when estimating the effects or differences.
Ethics
Approval by the local ethics committee should be stated with date of issue and registration number.
Results
Do not give the same data in more than one way. When summarizing the data, always include measures of variability and the number of subjects. Give the median and range—e.g., 60 (35–70) years, the mean and standard deviation—59 (SD 15) years, and the frequencies for nominal data. The results of matched data should be given in relevant form (e.g., the distribution of pairwise differences). Percentages should not be used if the sample size is less than 100.
Discussion
This section should contain a critical discussion of the results—e.g., the quality of the data (selection and information bias) and adequacy of the statistical analysis (confounding bias). It should also assess the relevant literature for or against the findings and if possible, the conclusions as regards clinical application or further research. Discuss, do not recapitulate, your results.
Tables
Each table should be self-explanatory, with an adequate title and a logical presentation of the data. Abbreviate words in the columns and explain in footnotes. Each column heading for numerical data should include the unit of measurement. Use SI units. Avoid unnecessary decimals! It is seldom advisable to use more than 2 digits for biologic measurements.
Digital illustrations
Should be used. A scanned picture or digital photo should usually be about 50 × 70 mm with a resolution of 300 dpi Dots per inch (DPI) is a measure of printing resolution, in particular the number of individual dots of ink a printer or toner can produce within a linear one-inch (2.54 cm) space. , which gives an uncompressed file size of 2 MiB A mebibyte is a unit of data storage that equals 2 to the 20th power, or 1,048,576 bytes in color and 500 KiB A kibibyte is a unit of data storage that equals 2 to the 10th power, or 1,024 bytes in gray-scale. A black and white drawing or graph may be scanned in 800 dpi Dots per inch (DPI) is a measure of printing resolution, in particular the number of individual dots of ink a printer or toner can produce within a linear one-inch (2.54 cm) space. bitmap, i.e. 1 bit TIFF. A 70 × 70 mm graph gives a file size of 600 KiB A kibibyte is a unit of data storage that equals 2 to the 10th power, or 1,024 bytes . The preferred format is a TIFF-file. The resolution of web illustrations (gif) is usually too poor. Color photos should be in CMYK CMYK is a subtractive color model used in color printing. The color model is based on mixing pigments of Cyan, Magenta, Yellow, Black(Key) in order to make other colors colors. The cost of color will be paid by Acta. Embed moderately JPEG compressed versions of your illustrations in your online submitted PDF file. These illustrations will not be used for production. Highlights, arrows and letters may be added to digital photos but keep a clean version of the photo for the layout process. Acta prefers to add these as a separate layer. For digital graphs, use a graphics program that can export EPS-files. Avoid frames around diagrams, diagrams with perspective drawing, and bar graphs or histograms (use tables). Symbols should be consistent throughout a series of figures. Each axis should be horizontally labelled, with a description of the variable it represents. Use sans serif letters (Arial or Helvetica). Make diagrams in black-and-white with gray or color areas, but avoid complex patterns.
Authors contributions
Describe in short what each author did.
Acknowledgments
Technical help and financial or other sponsorship may be acknowledged. Conflicts of interest, if any, should be clearly stated in the manuscript on submission. When the manuscript is accepted for publication, all authors are asked also to sign a conflict of interest statement.
References
We prefer the references to be cited by name and year (chronologically) of publication in the text instead of giving their numbers, i.e. one author, two authors or author et al. and year. Thus, the list of references should be given in alphabetical order.
Submission
Create an Adobe Portable Document File (PDF) of your full manuscript. You will need the Adobe Acrobat Writer Program or similar PDF creator program installed on your computer. We recommend that you write your manuscript as a Microsoft Word .le and embed all images, tables, figures etc. within the one file.
