You can still be a participant in the ORS 2026 Annual Meeting! The ORS Scientific Program Committee invites you to submit a Late-Breaking abstract.

Late-Breaking abstract submission is now open, until Monday, November 10, 11:59 PM Pacific.

You will be using your ORS username and password to login. If you do not have an ORS username, you will have the opportunity to create one.

One Podium session will be dedicated to selected late-breaking abstracts.

The late-breaking abstract submission allows for the submission of truly late-breaking scientific research for which no preliminary data was available at the time of August 25, 2025, abstract submission deadline.

  • Work that has been accepted prior to the ORS late-breaking submission deadline of November 10, 2025, for publication as a manuscript or will be presented prior to the ORS meeting in March 2026 is ineligible for consideration. Please note: Abstracts presented at an ORS regional/satellite meeting, i.e., Tendon Conference, PSRS, do not fall under these guidelines.
  • This late-breaking submission is not a mechanism to allow for updated data to complement preliminary research abstracts that were submitted by the general submission deadline of August 25.
  • Abstract must present results of work substantially performed prior to submission and no two abstracts that share one or more authors may overlap significantly in content. Abstract is based upon the best available evidence and does not promote or recommend relevant products or services as part of the abstract presentation.
  • Acceptance notices for Late-Breaking abstracts will be sent on December 3.

To submit your abstract:

To start, submit or edit your abstract(s), you will need to login with your ORS username and password.  If you do not have an ORS username, you will have the opportunity to create one.

Once you are logged in, you will be redirected to the ORS 2026 Abstract Submission site.

Abstract Submission Guidelines: New Requirements – Disclose Sex and Sample Size, if applicable

  • First write your abstract in Microsoft Word using Times New roman, 8-point font, 0.75” margins on all sides, following the ORS Formatting Guidelines.  A Template is available to create your abstract.
  • Be sure that all text (including title, authors and institutions, disclosures/COI, images and tables) fit onto one page.  3 images and/or tables are allowed per abstract.
  • If your research was approved by an IACUC/IRB or Ethics committee, please indicate, but you do not need to note the name or university. i.e., This study was approved by IACUC. This study was approved by an Ethics Committee.

New for 2026 – If applicable – the author will include sex and sample size. If only one sex is used an appropriate justification must be included in the abstract. Failure to provide justification will reduce overall abstract score and ranking.

  • References to product names are allowed in abstract, but it is not necessary to include the city/state or country.
  • Once you have the one-page abstract, you can complete the online submission by copying and pasting the body of the abstract in the online submission pages.
  • Complete ALL steps of the online submission.
  • Be sure to upload images supporting your abstract.
  • Next save the file as a PDF.  PDF documents of accepted abstracts will be used on the ORS online abstract search and on the mobile app.
  • Upload the PDF of your complete abstract, including title, authors, author disclosures/conflict of interests, images, references and acknowledgements.
  • There will be a $45.00 non-refundable fee to submit your late breaking abstract for the ORS 2026 Annual Meeting.
  • Once you complete all the steps in the online submission and submit payment, you will receive a green message and check mark on the “Review My Work” screen indicating “Your submission is COMPLETE.”

Tips for Submitting Abstract Content

When completing the information for your abstract submission are you providing information to address these questions?

Rationale and Objectives

  • Is the research question or hypothesis well-defined and relevant?
  • Is the gap in scientific knowledge and significance clearly articulated?
  • Is the scientific background clear – relevant work cited?
  • Is the abstract clear, well-organized, and concise?

Methods

  • Are the methods, data collection and analysis well-designed and clearly and succinctly described?
  • Are key details about animal use included:
    • Total number of animals used
    • Sex of animals specified
    • If one sex is used, is justification provided?

Results and Scientific Rigor

  • Quantitative data are included where applicable and include values such as means, standard deviations, percentages, fold changes, etc.
  • Are statistical analyses described or referenced?
  • Is statistical significance indicated, if applicable e.g., p-values, confidence intervals, effect sizes.
  • Overinterpretation: Do the results make claims beyond what the data show.
  • Missing control or comparison information: It should be clear what the results are being compared against.

Conclusions and Significance

  • Are conclusions supported by data?
  • Is the importance of the findings or relevance to the field clearly conveyed?
