PRESENTER INSTRUCTIONS
January 21st, 2007

Instructions for oral presentations and posters have now been posted. Please download the poster instructions for detailed information here.

INSTRUCTIONS for ORAL PRESENTATION:
Podium presentations will be 10 minutes long, followed by 5 minutes for discussion. Presentations will need to be uploaded to the organizers prior to the symposium. Please use the www.yousendit.com service to transfer the files. The service is free and allows sending large data files. Sending us the file ahead of time will ensure that the presentation will work properly on the provided computer. The file format will need to be compatible with Microsoft PowerPoint (Office XP). Deadline for submitting the presentation is Monday, February 5th.

INSTRUCTIONS for ORAL POSTER PRESENTATION:
Due to the overwhelming number of abstracts submitted to this meeting we will have for the first time an oral poster introduction in addition to the regular oral presentations. Adding this section allowed us to include six more abstracts. Oral poster introductions will be 3 minutes long and are limited to 5 slides (Title, Intro, Methods, Results and Discussion). There is no Q&A following the introduction. Presentations will need to be uploaded to the organizers prior to the symposium. Please use the www.yousendit.com service to transfer the files. The service is free and allows sending large data files. Sending us the file ahead of time will ensure that the presentation will work properly on the provided computer. The file format will need to be compatible with Microsoft PowerPoint (Office XP). Deadline for submitting the presentation is Monday, February 5th.

INSTRUCTIONS for POSTER PRESENTATION:
In addition to the podium presentation, we would like to invite you to present your research in a poster format during the dinner reception. This combination of podium and poster presentation is unique to this forum and we believe it will provide much needed networking opportunity for the presenting researcher. Please download the instructions detailing the poster specifications.

****** ANNOUNCEMENT AND FIRST CALL FOR ABSTRACTS ******
15th ANNUAL SYMPOSIUM on COMPUTATIONAL METHODS IN ORTHOPAEDIC BIOMECHANICS http://www.pre-ORS.org
Saturday, February 10th, 2007 University of California - San Diego La Jolla, California nline Registration & Abstract Submission Deadline: December 1st, 2006

Dear Colleagues:

This is the first announcement and call for abstracts for the 15th Annual Symposium on Computational Methods in Orthopaedic Biomechanics (the "pre-ORS" meeting). Detailed information on the meeting format and registration, maps to the meeting site, and the sponsors for the meeting can be found on the symposium website at http://www.pre-ORS.org.

Location: The symposium will be held on Saturday, February 10th, 2007 on the Campus of the University of California - San Diego (UCSD) in La Jolla, California, and hosted by the UCSD Department of Bioengineering and Whitaker Institute of Biomedical Engineering. The site is conveniently located, along the southern California coastline, ~15 miles north of the location of the Annual Meeting of the Orthopaedic Research Society. Registration will begin at 8:00 a.m., with presentations starting at 8:30 a.m. and continuing through the afternoon in a single-session format.

Registration: Pre-registration for the meeting will be available electronically at: http://www.pre-ORS.org/preregistration.html. We strongly encourage those interested in attending to pre-register for the symposium online through the meeting website so that we can adequately plan to accommodate everyone. Interest was great enough last year to require that registration be closed prior to the date of the symposium. As usual, registration and participation are free of charge.

Objectives: The purposes of the symposium are to communicate the most current ideas on the impact of computer-assisted techniques in the field of orthopaedic biomechanics, to educate scientists, engineers, and researchers in the use of these techniques, to promote the use of computer technology in biomechanics research, and to welcome new researchers into the field. In keeping with the tradition of the symposium, this meeting is a forum for "junior researchers" to present their ongoing research involving computation in orthopaedics. Therefore, presentations are expected to be given by the student/postdoc primarily responsible for the research. The symposium will provide ample opportunity for personal interaction with faculty and other symposium participants, and will be a unique educational experience for the presenters. The pre-ORS is the premier international forum on the use of a new breed of computer based tools in orthopaedic biomechanics.

Topics: All topics on computation in orthopaedics are welcome. Special topics of interest for this upcoming symposium are:

• Multi-Scale Approaches to Computer Modeling of Orthopaedic Tissue
• Finite Element Formulation of Non-Linear Constitutive Models
• Development of Algorithms for Simulation of Time-Dependent Processes
• Micro- and Nano-scale Biomechanical Modeling of Tissues

Abstract Submissions & Presentations: Abstracts are requested for all areas of computational research of interest to the general orthopaedic biomechanics community. As in the past, this meeting is a non-archival
forum for graduate students and postdocs to present their ongoing research. The deadline for submitting abstracts for the symposium is Monday, December 1st, 2006. Abstracts not exceeding one page should be sent via email as attachments in .pdf format to pre-ORS@rice.edu. Any questions concerning abstract submission can be sent to this email address as well. Please be sure to include abstract title, list of authors, and authors' affiliation(s). Text should be structured in a dual column format and font size not be smaller than 10pt.

Presentation: By submitting an abstract, it is understood that the primary author will present her/his work in person if the abstract is accepted, and that this work is not being presented at the Orthopaedic Research Society meeting. Presentations are expected to be given by the trainee (student or post-doc), primarily conducting the research, not by the PI. During the symposium the authors will be provided with two opportunities to present their work, 1) an oral presentation and 2) a poster presentation. With the submission of abstract, it is understood that the author agrees to an oral presentation, with the poster presentation being optional. Each oral presentation will be 10 minutes long with 5 minutes allotted for questions. The poster presentation will be informal during the social event in the evening.

KEY SYMPOSIUM INFORMATION:
