We are board certied in orthopaedic surgery and have participated in additional training to become specialized in the care of children’s musculoskeletal health and our practice reects this dedication. We, as a group, strive to become the authoritative source on such care through appropriate research that will lead to the best evidence-based patient care.POSNA MISSION STATEMENTTo improve the care of children with musculoskeletal disorders through education, research, and advocacy.CONNECT WITH POSNA DURING THE MEETINGAND SHARE YOUR EXPERIENCES#POSNA2020 @POSNA_org Pediatric Orthopaedic Society of North America (POSNA) linkedin.com/company/posna posna_orthoWebsites: POSNA.org, orthokids.org and posnacademy.org OrthopaedicTraumaAssociationorthopaedic-trauma-association@otatrauma@otatraumaOrthopaedicTraumaAssociationorthopaedic-trauma-association@otatrauma@otatrauma
Dear Colleagues,Consistent with the guidance provided by public health ofcials, POSNA is committed to reducing the spread of the COVID-19 virus and therefore made the disappointing decision to cancel the 2020 Annual Meeting in San Diego. Many options were explored, including rescheduling at a later time. Unfortunately, we were unable to identify a satisfactory date. The annual meeting is the highlight of the POSNA year. The program committee of Jeff Martus (Chair), Woody Sankar, Michelle Caird and Matt Oetgen had organized an outstand-ing program for San Diego. Some of the highlights in the initial schedule are listed below:• The pre-course “Transition to Adulthood: Orthopedics for the Adolescent,” organized by Noelle Larson. The course was designed to address many unique features of this age group and guide participants in the development of appropriate management strategies.• Recognition of award winners Behrooz Akbarnia (Distinguished Achievement), Charles Johnston (Humanitarian) and Donald Bae (Special Effort and Excellence). • Recognition of grant winners and industry partners.• A scientic program including 170 podium presentations, 40 paper posters, 80 ePosters, multiple symposia and a subspecialty day.• Presidential guest speaker Lori Karol addressing adapting to change in the new decade. • Presidential transfer to incoming president Michael Vitale.• Closing reception at the San Diego Air and Space Museum, located in historic Balboa Park. The museum is an afliate of the Smithsonian Institution and is home to a diverse collection of aircraft. The members of the Program Committee deserve special recognition. Since the cancellationof the on-site event, they have worked hard to make the meeting educational materials available to our members and meeting registrants. This reorganization required a great deal of time, effort and originality. It would not have been possible without the cooperation of the scientic program presenters. I appreciate the many hours Noelle Larson devoted to the development of the pre-course. The efforts of the local hosts Hank and Jill Chambers along with Peter and Cathy Newton also deserve recognition. Of course, all of this couldn’t have happened without the efforts of POSNA Executive Director Teri Stech, Meetings and Educa-tion Manager, Tara Long and the entire POSNA staff. On behalf of POSNA, thank you for your understanding. This has been an extremely difcult time that has resulted in signicant hardship throughout the world. I look forward to seeing you at the 2021 Annual Meeting in Dallas. Stephen Albanese, MDPresident, POSNA3WELCOME

POSNA 2020 PRE-COURSE18TRANSITION TO ADULTHOOD: ORTHOPEDICS FOR THE ADOLESCENTChair: A. Noelle Larson, MDDESCRIPTION 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 approachObjective 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 effectsObjective 3: Develop evidence-based communication skills to address unique needs and considerations specic to adolescentsACCREDITATION This activity has been planned and implemented in accordance with the accreditation requirements and policies of the Accreditation Council for Continuing Medical Education (ACCME) through the joint providership of the American Academy of Orthopaedic Surgeons and the Pediatric Orthopaedic Society of North America. The American Academy of Orthopaedic Surgeons is accredited by the ACCME to provide continuing medical education for physicians

SPEAKERS & AWARD RECIPIENTS, CONTINUED26CHARLES E JOHNSTON, MDHUMANITARIAN AWARDAfter growing up in the 50’s&60’s in Southern California, Charlie Johnston left the Beach Boys/Jan&Dean for the right coast attending Yale, Columbia P&S, and U.Va. before coming full circle back to Texas where family ancestors rst immigrated to south Texas in the 1870’s. After fellowship at TSRH with Tony Herring and Dennis Wenger and a brief stint at LSU NOLa, he has had but one job, secured only with a handshake, since 1985, and attributes his medical “attitude” directly to the TSRH philosophy that provides the most expert care available anywhere to any child with an orthopedic condition, without regard to the cost – actually, there was no billing dept.at TSRH - or amount of time to complete the task. Having known and been mentored by many giants – the aforementioned Herring and Wenger, Luque, Dubousset, Coleman, Hall, Goldner, Gillespie, Dimeglio, to name a few - it didn’t take much to transport all that knowledge and expertise to patients unable , through geographic or political iso-lation, to access care and escape the debilitation and impairment of neglected treatable conditions. The goal however was not to simply swoop in, operate, and be back in the ofce by Monday, but to identify, train and mentor local orthopods who could then effectively treat their own population while minimizing the effects of neglect and incompetence. He was rst challenged to venture to the Moski-to Coast, Honduras to treat children who could only be reached by air or water – no roads existed to connect to the usual “mission” sites in San Pedro Sula or inland. Then an opportunity to build a spine deformity program in the West Bank, Palestinian Territory arose through the auspices of Hugh Watts and The Palestine Childrens Relief Fund(PCRF). There were no local physicians in Moskito environs, so those patients had to be brought to Dallas for surgery and rehab….but once we penetrated the physical and political isolation of Palestine, it was just a matter of enlisting other US mentors and an Israeli colleague to develop now three well-trained and competent “residents” who engage as COUR scholars and who have become our junior colleagues locally. The message: there are probably an innite number of patients and places needing POSNA expertise, and many are covered by regularly-visiting brigades. But imagine the efciency and the benet when you can teach, train and turn over care to someone who lives locally and becomes the pediatric orthopedist for their community, region, even nation. The value of having local pediatric orthopedic colleagues with real “skin in the game” is a worthy goal for POSNA colleagues who can commit more to the patients who are otherwise reliant only on the visiting brigades and Mercy ships or have the means to travel to come to us.

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 reect 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, Coordination, 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 present 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.

2020 SUBSPECIALTY DAY PROGRAMHAND SUBSPECIALTY DAY – 59 minutesCo-Chairs: Claire Manske, MD and Lindley Wall, MDConditions of the pediatric upper limb span from congenital to traumatic presentations, and creates challenging, and at times, controversial treatment approaches. This session will include presentation of 6 chosen abstracts, followed by discussion. Subsequently, four case presentations of interesting pediatric upper extremity cases will be presented – ranging from the shoulder to the ngers – followed by lively discussion of treatment approaches by the expert panel. Pre-operative assessment, surgical technique, and pure opinion (somewhat literature based) will be discussed and debated.

FOOT/ANKLE SUBSPECIALTY DAY – 44 minutesCo-Chairs: Derek Kelly, MD and Jennifer Laine, MDTo 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 proce-dures either do not give adequate correction or allow for early recurrence. 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. At the end of this session:1. The attendee will gain a better understanding of the appropriate indications for hindfoot and forefoot fusions2. The participant will learn arthrodesis surgical technique pearls and potential pitfalls3. The attendee will be able to explain the potential risks associated foot arthrodesis, especially when poorly indicatedPAPER 78The Development of a Clubfoot Outcome Score for Ponseti Treated Idiopathic Clubfeet: Results of a Pilot Study with 40 Unilateral ClubfeetChristine Douglas, CPS; Roisin Delaney; Neil Segaren, FRCS (Ortho); Matt Thornton; Sally Tennant, MDRoyal National Orthopaedic Hospital, Stanmore, UK, United Kingdom 44

The rst will be to provide a comprehensive 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 difcult 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.

83POSNA ANTITRUST POLICYIt shall be the policy of the Pediatric Orthopaedic Society of North America (POSNA) to be in strict compliance with all Federal and State Antitrust laws, rules and regulations. Therefore: These policies and procedures apply to all membership, board, committee, and all meetings attended by representa-tives of the POSNA.Discussions at POSNA meetings often cover a broad range of topics pertinent to the interests or concerns of orthopaedic surgeons. As a general rule, except as noted below, discussions at POSNA meetings can address topics without raising antitrust concerns if the discussions are kept scrupulously free of even the suggestion of private regulation of the profession. However, a number of topics that might be (and have been) discussed at POSNA meetings may raise signicant complex antitrust con-cerns. These include:• Membership admissions, rejections, restrictions, and terminations;• Method of provision and sale of POSNA products and services to non-members;• Restrictions in the selection and requirements for exhibitors at the POSNA Annual Meeting or in CME activities; • Collecting and distributing certain orthopaedic practice information, particularly involving practice charges and costs; • Obtaining and distributing orthopaedic industry price and cost information;• Professional certication programs; • Group buying and selling; and• Inclusions or exclusion of other medical societies in organizational activities or offerings. When these and related topics are discussed, the convener or members of the POSNA group should seek counsel from its General Counsel. POSNA urges its Board, committees and other groups not to participate in discussions that may give the appearance of or constitute an agreement that would violate the antitrust laws. Notwithstandingthis reliance, it is the responsibility of each POSNA Board or committee member to avoid raising improper subjects for discussion. This policy has been prepared to ensure that POSNA members and other participants in POSNA meetings are aware of this obligation.The “Do Not’s” and “Do’s” presented below highlight only the most basic antitrust principles. POSNA members and others participating in POSNA meetings should consult with the General Counsel in all cases involving specic questions, interpretations or advice regarding antitrust matters. Do Not’s1. Do not, in fact or appearance, discuss or exchange information regarding: a. Individual company prices, price changes, price differentials, mark-ups, discounts, allowances, credit terms, etc. or any other data that may bear on price, such as costs, production, capacity, inventories, sales, etc. b. Raising, lowering or “stabilizing” orthopaedic prices or fees; c. What constitutes a fair prot or margin level; d. The availability of products or services; or e. The allocation of markets, territories or patients.2. Do not suggest or imply that POSNA members should or should not deal with certain other persons or companies.3. Do not foster unfair practices regarding advertising, standardization, certication or accreditation.4. Do not discuss or exchange information regarding the above matters during social gatherings, incidental to POSNA-sponsored meetings.POSNA ANTITRUST POLICY
5. Do not make oral or written statements on important issues on behalf of POSNA without appropriate authority to do so. The Do’s1. Do adhere to prepared agenda for all POSNA meetings. It is generally permissible for agendas to include discussions of such varied topics as professional economic trends, advances and problems in relevant technology or research, various aspects of the science and art of management, and relationships with local, state or federal governments. 2. Do object whenever meeting summaries do not accurately reect the matters that occurred. 3. Do consult with General Counsel on all antitrust questions relating to discussions at POSNA meetings.4. Do object to and do not participate in any discussions or meeting activities that you believe violate the antitrust laws; dissociate yourself from any such discussions or activities and leave any meeting in which they continue. Special Guidelines for Collecting and Distributing Information The collection and distribution of information regarding business practices is a traditional function of associations and is well-recognized under the law as appropriate, legal and consistent with the antitrust laws. However, if conducted improperly, such information gathering and distributing activities might be viewed as facilitating an express or implied agreement among association members to adhere to the same business practices. For this reason, special general guidelines have developed over time regarding association’s reporting on information collected from and disseminated to members. Any exceptions to these general guidelines should be made only after discussion with General Counsel. These general guidelines include:1. Member participation in a statistical reporting program is voluntary. A statistical reporting program should be conducted without coercion or penalty. Non-members should be allowed to participate in a statistical reporting program if eligible; however, if a fee is involved, non-members may be charged a reasonably higher fee than members. 2. Information should be collected via a written instrument that clearly sets forth what is being requested.3. The data that is collected should be about past transactions or activities; particularly if the survey deals with prices and price terms (including charges, costs, wages, benets, discounts, etc.), it should be historic, i.e., more than three months old.4. The data should be collected by either POSNA or an independent third party not connected with any one member.5. Data on individual orthopaedic surgeons should be kept condential.6. There should be a sufcient number of participants to prevent specic responses or data from being attributable to any one respondent. As a general rule, there should be at least ve respondents reporting data upon which any statistic or item is based, and no individual’s data should represent more than 25% on a weighted average of that statistic or item. 7. Composite/aggregate data should be available to all participants – both members and non-members. The data may be categorized, e.g., geographically, and ranges and averages may be used. No member should be given access to the raw data. Disclosure of individual data could serve to promote uniformity and reduce competition.8. As a general rule, there should be no discussion or agreement as to how members and non-members should adjust, plan or carry out their practices based on the results of the survey. Each member should analyze the data and make business decisions independently. POSNA ANTITRUST POLICY, CONTINUED84
