The Pediatric Orthopaedic Society of North America (POSNA) has been selected to be our 2025 Guest Clinical Society. Bringing our organizations together in our Guest Clinical Society program will strengthen and improve collaboration toward our common goals.

Scientific Symposium

In Collaboration with ORS Innovation Committee and Guest Clinical Society-Pediatric Orthopaedic Society of North America

Sunday, February 9
2:30 pm – 4:00 pm
West 301D

Organizers:
Matthew Halanski, MD, Phoenix Children’s Hospital; Roger Cornwall, MD, Cincinnati Children’s Hospital; Noelle Larson, MD, Mayo Clinic; Gabriela Graziani, PhD, Polytechnic University of Milan; Neharika Bhadouria, PhD, Purdue University

Pediatric orthopedics lives at the heart of orthopedic surgery, fulfilling its etymology of ‘straightening children’ to preserve function and prevent degenerative conditions for a lifetime of benefit.  However, challenges from small patient populations, variability in clinical presentation, and congenital malformations slow the progress in answering important translational research questions.  In this symposium, speakers from the Pediatric Orthopedic Society of North America (POSNA) will outline pressing needs in pediatric orthopedics, including spine and hip problems, the growth plate, infection and bone healing. This symposium will describe the top clinical problems identified by POSNA members through a consensus-based process. Organizers from the ORS will then facilitate collaborative roundtable discussion around these topics, with the ultimate goal of identifying research approaches to collaboratively meet these needs and foster collaboration among clinicians and researchers that can work to address them.

Speakers:

Noelle Larson, MD, Mayo Clinic
Intro Consensus-Based Research Agenda

Todd Milbrandt, MD, Mayo Clinic
