YOU’RE INVITED
Dear Colleagues,
On behalf of POSNA President Stephen Albanese, MD and the 2020 Program Committee (Michelle Caird, MD,
Wudbhav (Woody) Sankar, MD, and Matt Oetgen, MD, and I) it is a great honor to invite you to attend the 2020
Annual Meeting of the Pediatric Orthopaedic Society of North America in San Diego, California on May 12-16, 2020.
Once again, a record number (1,061) of abstracts were submitted and were graded by a combination of invited and
volunteer readers. Thank you to all 100+ POSNA members who volunteered and have helped to shape a great meeting.
All 170 podium presentations, 40 posters, and 80 ePosters are outstanding. Now in its 2
nd
year, there will be 18 video
abstracts showing in the Video Theater, and also available on POSNAcademy. The meeting agenda follows:
The Pre-Course begins Wednesday morning: Transition to Adulthood: Orthopedics for the Adolescent
chaired by Noelle Larson, MD.
The 6
th
Annual Arabella Leet, MD Young Member Forum will be held on Wednesday during lunchtime
from 12:20 PM - 1:20 PM and it is organized by Megan Johnson, MD.
The rst scientic session begins at 1:30 PM on Wednesday afternoon and will be followed by the
Opening Ceremony Wednesday evening at 6:30 PM.
Thursday is the Symposia Program from 10:00 AM -12:00 PM offering POPS, COUR, Research,
Disaster Response Planning, Practice Management and Bone Health. Please take advantage of
San Diego and enjoy the free “outdoor recess” on Thursday afternoon.
The Business Meeting will take place at lunchtime on Friday 11:45 AM - 1:15PM to allow study group
meetings in the mornings before the start of the scientic sessions.
Friday afternoon is Subspecialty Day, chaired by Woody Sankar, MD. This is devoted to eight sessions
covering advanced topics in Spine, Hip, Sports, Upper Extremity, Foot, Trauma, Neuromuscular, and
Lower Extremity. Each session will have 6-12 podium presentations that are staggered through the
afternoon so attendees can move to different sessions to hear either the paper session or the programs
put together by the Subspecialty Day program chairs.
This year’s local co-hosts, Peter Newton, MD and his wife, Cathy Newton, and Hank Chambers, MD, and his wife, Jill
Chambers, were central in identifying great offerings for Thursday afternoon and the venue for our closing reception, the
San Diego Air and Space Museum.
The Annual Meeting is the premier venue for pediatric orthopaedic research and education presented in a uniquely
collegial and social atmosphere. We sincerely hope you will plan to join us for what will be a fantastic event.
We look forward to seeing you in San Diego!
Sincerely,
Jeff Martus, MD

TRANSITION TO ADULTHOOD:
ORTHOPEDICS FOR THE
ADOLESCENT
Chair: A. Noelle Larson, MD
WEDNESDAY, MAY 13, 2020
8:00 AM – 12:00 PM
DESCRIPTION
Pediatric orthopedic surgeons care for children from
infancy to adulthood, and the adolescent years present
special challenges both in surgical decision-making and
patient and parent communication. In this precourse, we
will discuss when to introduce adult treatment strategies in
the adolescent years and how to achieve age-appropriate
orthopedic care. Further, at every visit with adolescents
and young adults, there is an opportunity to intervene
and change the trajectory of young people’s health by
promoting informed shared decision making and guided
autonomy. This partnership is critical in the treatment
of adolescents. This course will discuss evidence-based
communication skills to improve patient/parent/surgeon
conversations and discuss longterm implications of
pediatric orthopedic treatment.
LEARNING OBJECTIVES
Upon completion of this program, participants should be
able to:
Objective 1: Differentiate orthopedic conditions which are
best treated with adult treatment strategies
rather than a pediatric orthopedic approach
Objective 2: Assess treatment approaches in adolescents
that may result in future harm or altered
health related quality of life and identify how
to mitigate potential deleterious effects
Objective 3: Develop evidence-based communication
skills to address unique needs and consider-
ations specic to adolescents
ACCREDITATION
This activity has been planned and implemented in
accordance with the accreditation requirements and
policies of the Accreditation Council for Continuing

YOUNG MEMBER FORUM
Chair: Megan Johnson, MD
12:20 PM–1:20 PM
The POSNA Young Member Forum is held in honor of Dr. Arabella
Leet, who passed away in 2013 after a sudden illness. Dr. Leet
was a highly accomplished Pediatric Orthopaedic Surgeon with a
special interest in children with Cerebral Palsy. At the end of her
career, she served as Chief of the Shriner’s Hospital in Honolulu,
Hawaii.
This year the Young Member Forum will focus on a variety of topics
relevant to pediatric orthopaedic surgeons in the rst 5 years of
their practice, as well as residents and fellows pursuing careers in
pediatric orthopaedic surgery. Members of POSNA will share
their own personal experience and wisdom on the topics selected,
with time for discussion at the end of the symposium.
Lunch will be served.

PEDIATRIC ORTHOPEDIC GLOBAL OUTREACH
(POGO) DELIVERY OF PEDIATRIC ORTHOPEDIC
GLOBAL OUTREACH IN 2020 AND BEYOND
Co-Chairs: Eric Fornari, MD and Michael Heffernan, MD
Pediatric orthopedists have been at the forefront in global health
for the last half century and have helped our profession and
society in meaningful and impactful ways. In 2001, the Children’s
Orthopedics in Underserved Regions (COUR) committee was formed
to help POSNA members carry out this work in resource-limited
environments. The COUR committee recently changed its the
name to the Pediatric Orthopedic Global Outreach (POGO)
committee in order to better reect the evolved role the committee
has for our membership and the Society. The mission of POGO
will be carried out through a combination of Education, Coordi-
nation, and Research. This year’s symposium will focus on how to
develop a sustainable global outreach program. We will cover the
ethics of getting involved with such work as well as ideas for how
to track outcomes to ensure all goals are being met. Finally, we
will give our members a chance to discuss some of the programs
they have developed with the goal of stimulating discussion,
collaboration, and engagement. This is an opportunity to build
on the work of the visionary leaders who laid the foundation for us
to shape the future.

PEDIATRIC BONE HEALTH FOR THE
ORTHOPAEDIC SURGEON
Co-Chairs: Barbara Minkowitz, MD, Jenn Beck, MD,
and Laura Tosi, MD
This year’s Pediatric Bone Health for the Orthopedic Surgeon
Symposium will focus on the following topics: Bone health quality
versus quantity including determinants of bone strength and
toughness; Current bone health screening addressing work-up

acquisition during childhood and adolescence including factors
that affect bone mass that are nonmodiable and modiable
and populations at risk for reduced bone mass; Treatment of
children with fragility fractures using bone health in children with
disabilities as a model for reducing fracture rates and improving
quality of life in children with a primary bone disorder; Options for
diagnosing, treating, and managing children at high risk for recur-
rent fracture; Bone health in trauma including delayed/nonunion
risk fractures in fracture patients and non-weight bearing effects
on bone healing; Bone health in the young athlete and update
on NSAIDS and healing; Metabolic considerations for deformity
correction, regenerate consolidation/osteotomy healing. We will
conclude with a review of evidence-based protocols for supple-
mentation and a Q&A panel session.

TRAUMA: DISASTER RESPONSE FOR THE
PEDIATRIC ORTHOPAEDIC SURGEON
Co-Chairs: Chris Souder, MD, Stephanie Holmes, MD
and Mark Sinclair, MD
This year’s Trauma Symposium is focused on aspects of disaster
response and mass casualty care that impact pediatric orthopaedic
surgeons. We will review what care will need to be provided to
pediatric patients in these circumstances and what government
regulatory agencies expect from trauma centers. We will review
past disasters in the United States, discuss what went well and
what did not, and discuss how to use simulation in preparation for
disasters that are most likely to affect your hospital and com-
munity. We will discuss international disaster response using
knowledge gained from the Haitian earthquake of 2010. We will
then conclude by reviewing how course participants can prepare
themselves, their departments and hospitals, and their community
in providing a well-organized and effective disaster response.

Co-Chairs: Derek Kelly, MD and Jennifer Laine, MD
3:50 PM–5:30 PM
To Fuse or Not To Fuse?
As pediatric orthopaedic surgeons, our treatment goals often
involve maximizing long-term function and minimizing pain.
Arthrodesis in the pediatric or adolescent foot and ankle has the
risk of stiffness, early degeneration of neighboring joints, and
pain. Unfortunately, in some cases, joint sparing procedures
either do not give adequate correction or allow for early recur-
rence. In this year’s Foot and Ankle symposium, “To Fuse or Not
to Fuse?,” we will focus on the complexity of this decision-making
process. Our foot and ankle specialists, through a case-based
approach, will illustrate when joint-sparing surgery should be
employed, and when it is time to proceed with arthrodesis. Our
experts will highlight their indications, treatment algorithms and
surgical techniques for fusions in the foot. They will then demon-
strate this approach through discussion and debate over case
examples, and audience participation will be encouraged.
At the end of this session:
1. The attendee will gain a better understanding of the
appropriate indications for hindfoot and forefoot fusions
2. The participant will learn arthrodesis surgical technique pearls
and potential pitfalls
3. The attendee will be able to explain the potential risks
associated foot arthrodesis, especially when poorly indicated

HIP
Co-Chairs: Travis Matheney, MD and Rachel Goldstein, MD
1:40 PM–5:30 PM
This session will have two aims. The rst will be to provide a com-
prehensive overview of how we assess hip cartilage and arthrosis
in preservation surgery. We will be discussing the latest updates
in imaging, bio markers, and biologics. Experts in the eld will
review the latest developments and discuss their applicability to
difcult to manage hip preservation cases. The second aim will be
to address the use of ultrasound imaging in the infant hip, both in
and out of the operating room. We will focus on how ultrasound
may improve our ability to assess hip reductions and perfusion
in the operating room, as well as how to include it in your clinical
practice.

This session aims to provide a comprehensive approach to the
management of re-tears of the ACL graft following primary ACL
reconstructive surgery – one of the most difcult problems to
treat in young athletes. From the epidemiology of these injuries
to the preoperative assessment and intraoperative decision-making
algorithms, experts in the eld will review in detail their own
evidence-based approaches to the problem. Participants will leave
this session with a “toolkit” of practical recommendations for
incorporation into their own pediatric sports medicine practices.

This Masters Techniques session will feature a wide variety of
state-of-the-art approaches to the management of patellar
instability in children and adolescents by leaders in the eld of
pediatric sports medicine. Participants will leave this session
armed with the tools to evaluate and manage patellar instability
in children regardless of its etiology and the physeal status.

TRAUMA
Co-Chairs: Mauricio Silva, MD and Mark Sinclair, MD
1:40 PM–5:30 PM
The Trauma Subspecialty session will consist of three different
components, all of which should be of interest to pediatric ortho-
paedic surgeons involved in trauma care. There will be scientic
paper presentations, with our two experienced discussants leading
a lively question and answer segment about the latest controver-
sies in trauma care.
There will also be two didactic sessions. The rst will discuss turn-
ing your trauma M&M into trauma QI (Quality Improvement). This
is an area that is highly stressed in ACS verication. Three specic
types of complications seen in trauma care will be discussed, and
applicable techniques of turning complications into improvement
opportunities will be stressed.
The second will discuss variations of common fracture care, high-
lighting three injuries seen almost daily in a pediatric orthopaedic
practice. Is this just benign practice variation or should there be
more specic treatment protocols for these common injuries?
As always, audience participation will be encouraged.
