On behalf of the Orthopaedic Research Society, we look forward to welcoming you to the ORS 2013 Annual Meeting in San Antonio, Texas. At the 2013 meeting we will continue to address the educational and professional development interests of our attendees through our professional advancement series, co-sponsored symposia and workshops, technical exhibits, industry-related events, research interest groups, mentoring opportunities, and more. Experienced investigators will conduct walking tours of posters in their areas of expertise. Back by popular demand are the Spotlight Sessions, with invited experts in various fields presenting their work in themed sessions and the Professional Advancement Series. We will also offer the Clinical Research Forum. This one-day research forum is intended to cover topics related to the design, analysis, and trouble-shooting of clinical research. This research forum will run in parallel with our other programming on Sunday, January 27, 2013.
