Kottmeier, MDAnnual Meeting Program ChairDear Colleagues,On behalf of the OTA Program Committee and President Heather Vallier MD, I am pleased to invite you to the 37th Annual Meeting of the Orthopaedic Trauma Association (OTA) to be held in Fort Worth, Texas, from October 20 to 23, 2021. It is our hope and expectation that the present favorable pandemic trajectory will enable us to gather again in October. As a profes-sional medical society, we have remained vibrant over the past year despite not being able to meet in person, but I know our membership and colleagues are looking forward to a long-awaited reunion this forthcoming fall, a time of year cherished for OUR annual meeting. Last year’s virtual meeting was a success, conrmed our resourcefulness as a society, and familiarized us with alternative mechanisms of information delivery. Lessons learned will enable us to supplement our live event with virtual content both live and on demand.In the months leading up to the meeting, the Annual Meeting Committee reviewed over 1,000 scientic abstracts, more than 80 symposia/breakouts, and over 100 technical tricks and innovations. This has culminated in a program that includes the latest cutting-edge, high quality research and state-of-the-art treatment for musculoskeletal injuries. Paper presentations will begin with a “Program Highlights” session, featuring nine original research presentations of the highest quality, many with the potential to be practice-changing. Additionally, there will be many topic-centered paper presentations. Four main symposia will include the evermore important topics of physician wellness and diversity in medicine and our professional society in addi-tion to current surgical procedural “hot topics”. Included within the meeting will be 26 breakout sessions, each with a specic focus to satisfy your interest. There will be over 200 posters in the exhibit hall, and the continuation of a highly regarded novel category entitled Technical Tricks/Innovation in e-poster format.This year we welcome John Border Memorial Lecturer; Iraqi war veteran Noah Galloway who will deliver a talk titled, “Living with no Excuses.”Premeeting events will include:• Inaugural events; Local rst responders session/OTA fellow reception and research event/ OTA Fireside – The Case That I have Learned the Most From: An Evening with Your Colleagues• Orthopaedic Trauma Boot Camp • Orthopaedic Trauma for NPs and PAs• International Trama Care Forum • E/M and Surgical Coding Course• Young Practitioners Forum • Resident Comprehensive Fracture Course• Pelvis and Acetabulum Course • Soft Tissue Coverage Skills CourseThe OTA will continue to monitor any evolving pandemic related issues. The safety of our meeting attendees is a top priority, and we will be working closely with our Fort Worth venue partners to ensure CDC and city/state safety guidelines are in place at the time of the meeting.Your presence and contributions to the meeting are welcomed. The OTA Leadership is looking forward to an academically engaging in person meeting with the social gratications that accompany and nurture it. The collective ambition and mission is to offer a meeting of quality in an environment both safe and collegial. See you in Fort Worth!Sincerely,Stephen A. Kottmeier, MDProgram Chair®NEW!

Managing Complex Humerus Fractures: From Proximal to Distal Moderator: Andrew M. Choo, MD Faculty: Timothy S. Achor, MD Michael J. Gardner, MD Eben A. Carroll, MD Learning Objectives • Identify fracture patterns and characteristics which can pose unique difculties. • Aid with decision-making, planning, and options for complex humerus fractures. • Demonstrate surgical techniques to successfully manage these injuries. Description This breakout session will present case-based discussions on the management of difcult problems with humerus fractures. Proximal, diaphysial, and distal humerus fractures will be examined with special attention to unique fracture problems, including fracture-dislocations, ballistic injuries, segmental fractures, bone loss, and nonunions/malunions. This breakout focuses on challenging problems seen in humeral fracture management which aren’t common-ly discussed in other forums. The case-based nature allows for extensive audience partici-pation as well.Friday, October 22, 2021 6:30 AM - Concurrent Breakout Sessions 7:30 AM Pelvic and Acetabulum Fractures Moderator: Paul Tornetta III, MD Faculty: David C. Templeman, MD Reza Firoozabadi, MD Michael S. Kain, MD Andrew H. Schmidt, MD Learning Objectives • To understand indications for surgery of pelvic and acetabular fractures • To be exposed to multiple xation and reduction tactics • To understand the controversies in the management of pelvic and acetabular fractures Description This is a case-based review of controversial and complex pelvic and acetabulum fractures. It will focus on the indications for surgery as well as intra-operative reduction and xation tactics. From Fixation to Revision in Periprosthetic and Interprosthetic Hip & Knee Fractures: When, How and Getting it Right Moderator: Frank A. Liporace, MD Faculty: Richard S. Yoon, MD Derek J. Donegan, MD, MBA Mark Gage, MD Learning Objectives • Take away strategies for identifying stable versus loose implants in the periprosthetic (PPFx) THA/TKA Fracture setting. Additionally --- what do I do with an interprosthetic fracture? • Fixation strategies, tips and tricks and avoiding pitfalls for PPFx about the acetabulum, proximal and distal femur. • When and how --- revision strategies for a loose cup, loose femoral stem/compo- nent with and without good bone stock. Description This breakout session will offer a case-based, interactive strategy and update on the xa-tion and revision of periprosthetic THA/TKA fractures. Also, treatment of interprosthetic fractures will also be highlighted for partic-ipants. We all know that periprosthetic hip and knee fractures continue rise and are a clinical concern especially with its morbidity/mortality equaling those of hip fractures -- so providing tips/tricks to efcient and effec-tively treat these is essential to the everyday

Uppal, MD, MS Faculty: Brad J. Yoo, MD Gregory John Della Rocca, MD, PhD, FAAOS, FACS Stephen K. Benirschke, MD Learning Objectives • The registrant will learn surgical strategies and tips for successful midfoot reconstruction. Additional discussion and case examples will be on both surgical techniques and tips for initial provisional xation as well as techniques for denitive ORIF vs primary fusion. • The registrant will learn tips for successful xation of Chopart fractures and/or dislocation injuries. • The registrant will learn surgical strategies and tips for successful midfoot reconstruction. Additional discussion and case examples will be on both surgical techniques and tips for initial provisional xation as well as techniques for denitive ORIF vs primary fusion. Description Through detailed case based discussion the registrant will further their knowledge on how to manage complex midfoot and Cho-part joint injuries. Focus will be on scrutiniz-ing xrays and discussing surgical technique that highlights tips for obtaining stable mechanical xation. Further discussion will address the proper management of com-plex midfoot injuries where initial denitive xation has failed. Complex foot injuries are commonly managed by orthopaedic trauma surgeons. These injuries if managed poorly can result in outcomes that are devastating to the patient. This symposium will address in detail the surgical techniques and tips to manage these injuries correctly the rst time. Although this symposium was done last year, judging by the large attendance and lengthy discussion with faculty during and after the course, it is apparent that many surgeons feel this topic is important and desire further understanding. We will focus solely on case presentations that highlight in depth surgical techniques and steps needed to achieve successful reconstruction of both primary and failed xation. This is a must have! Challenges in Non-union Treatment - A Case-Based Symposium Moderator: Paul S. Whiting, MD Faculty: J. Spence Reid, MD Gerald J. Lang, MD David Goodspeed, MD Learning Objectives • Understand the mechanical and biological principles of fracture healing. • Learn a systematic approach to non-union workup and pre-operative planning. • Understand treatment principles and techniques for non-unions. Description Faculty will use a case-based approach to illustrate principles and techniques of non-union treatment. Principles of fracture healing (mechanical and biological) and strategies for non-union workup and pre-op-erative planning will also be reviewed. This proposal represents a follow-up to mini-sym-posia we offered at the 2018 and 2019 OTA meetings. Based on feedback from partici-pants at the 2018 symposium, we shortened the didactic portions, leaving additional time for case presentations and discussion with attendees. This was very well received at the 2019 meeting, and we would like to offer this session again following a similar format but providing new cases to illustrate the key concepts/objectives we would like partici-pants to gain from the session.

O’Toole, MD Prism Schneider, MD, PhD Steven F. Shannon, MD Emil H. Schemitsch, MD Gerard Slobogean MD, MPH Learning Objectives • Latest evidence regarding best treatment strategies for ankle syndesmosis (tight- rope vs screws) as well as ail chest injuries (surgery vs non-op) • Latest evidence regarding hip fractures in elderly: is THA better than a hemi, and how long should a cephalomedullary nail be. • Latest evidence on adjuncts to fracture xation: use of vancomycin powder, vitamin D supplementation, and negative pressure wound therapy. Description The aim of this symposium is to highlight practice changing clinical trials presented/published in the last 2 years, and provide clear evidenced based recommendations, for the treatment of common fractures and orthopaedic conditions. There have been multiple recent high-quality studies present-ed and published in the eld of orthopaedic trauma. Unfortunately, many surgeons are unaware of the latest evidence and recom-mendations (weather in the community or academics). This session highlights a number of award winning and practice changing clinical trials. This session is applicable to all orthopaedic surgeons attending the OTA, as well as residents, PAs, and allied health. The topics are relevant to those working at large academic centers as well as smaller com-munity hospitals. The session has a diverse and international faculty. The speakers are experts in the topic they will be presenting, many as the principal investigator of the study discussed. Each speaker will have 7 minutes to speak, and there will be 40 minutes for discussion and audience partici-pation at the end. A similar symposium was presented several years ago which was very successful and well received by the audience. 9:00 AM - Break9:40 AM

Description This breakout session will offer a case-based, interactive strategy and update on treatment techniques for supracondylar distal femur fractures with and without articular involve-ment. Treatment of supracondylar nonunions will be also be highlighted for participants. Despite signicant advances in orthopae-dic trauma, the ideal xation strategy and implant construct for supracondylar distal femur fractures remains unknown. There remains a relatively high nonunion rate and a signicant complication prole, specically in the geriatric population. This breakout session provides tips/tricks to efciently and effectively treat these injuries essential to all orthopaedic surgeons. Diversity and Inclusion in Orthopaedic Trauma Moderator: Joseph R. Hsu, MD Faculty: Anna N. Miller, MD Hassan R. Mir, MD, MBA Paul B. Gladden, MD Heather A. Vallier, MD Learning Objectives • Dene the problem of lack of diversity among orthopaedic trauma surgeons. • Discuss impact of improving diversity in the subspecialty on surgeons as well as patients. • Identify practical solutions to execute this in own practice. Description Orthopaedic surgery has lagged behind other medical specialties in the recruitment and promotion of underrepresented minori-ties to include women; orthopaedic trauma has done even worse than many Orthopae-dic Subspecialties in recruiting and promot-ing diverse surgeons. Data suggests that increased diversity in physicians decreases disparities in care. This panel will dene the problem, describe opportunities to improve both quality of care for patients and for surgeons and other team members, and provide practical and actionable solutions to execute this in our own divisions, depart-ments, and specialty. As a specialty, Ortho-paedic Surgery has a diversity problem and that problem is even worse in orthopaedic trauma. It is critical to have open and honest discussion about the impact on surgeons as well as patient care, as well as to discuss ways to improve diversity among orthopaedic trauma surgeons.Friday, October 22, continued 10:00 AM - Concurrent Breakout Sessions11:00 AM Navigating Work and Life Stressors as an Orthopaedic Traumatologist Moderator: Matthew R. Garner, MD Faculty: Derek J. Donegan, MD, MBA Milton L. Routt, MD Milton T. M. Little, MD Jonah Hebert-Davies, MD Learning Objectives • An improved understanding of stressors and challenges that Orthopaedic Trauma surgeons face through discussion and personal experiences of faculty. • Statistics surrounding physician suicide. • Tools and resources available for those experiencing stress, loss, or mental challenges. Description This session will focus discussing stressors that occur in a provider’s life, both at work and at home. The faculty will use personal experiences to promote an open discussion of these stressors in hopes of starting a pro-cess of destigmatization. Participants will be encouraged to continue these conversations at their home institution with the goal of improving communication around topics that are often avoided. Provider mental health is routinely overlooked, a fact that has become more apparent with the recent, unexpected loss of colleagues. It is important that OTA members understand that their struggles are rarely unique and that many of us share sim-ilar experiences. Further, it is essential that we promote discussion and awareness of these stressors while avoiding internalization. Treatment of Supracondylar Femur Fractures: Plating, Nailing and Nonunions Moderator: Frank A. Liporace, MD Faculty: Michael A. Maceroli, MD Richard S. Yoon, MD John P. Ketz, MD Marcus F. Sciadini, MD Learning Objectives • Provide operative tips and techniques for treating supracondylar distal femur fractures with both locked plating and intramedullary strategies. • Focus on the geriatric supracondylar femur fracture and the advent of the nail-plate combination technique to allow early weight-bearing and prevent complications.

Description The goal of this breakout session is to provide operative management strategies to avoid complications and achieve desired outcomes. Presentations will be case-based and include everything from the simple to complex fractures. Strategies will focus on the latest decision-making and xation op-tions to maximize outcomes. Higher energy ankle/pilon fractures still offer a challenging clinical scenario to the orthopaedic trauma-tologist/general orthopaedist. Minimizing complications are based on appropriate planning and xation execution --- this case-based breakout will provide the necessary education in this important trauma topic essential to OTA attendees.

Little, MD Learning Objectives • Understand pearls and pitfalls of intramedullary nailing of proximal femur femur fractures • Appreciate ideal indications for plate xation of proximal femur fractures • Recognize surgical tactics to treat femoral neck fractures and possible associated postoperative complications Description High energy proximal femur fractures can be challenging injuries to manage. This break-out session will utilize case presentations to demonstrate common intra-operative pitfalls and errors that frequently lead to postop-erative failure. Techniques and indications will be demonstrated to optomize success though the use of intramedullary nails, plate xation and femoral neck xation. Surgically managed high energy proximal femur fractures are plagued by high rates of postoperative malalignment and associated nonunion. This breakout session will seek to clarify proper indications for plate and nail xation and demonstrate specic reproduc-ible intraoperative techniques for success-ful application of these devices. Technical pearls for femoral neck xation will also be discussed. State of the Art for Operative Management of Femoral Head Fractures Moderator: Brett D. Crist, MD Faculty: Kyle Schweser, MD John C.

Moderator: Jason W. Nascone, MD Faculty: Milton L. Routt, MD Adam J. Starr, MD Robert V. O’Toole, MD H. Claude Sagi, MD Learning Objectives • The learner will understand the denition of “Gray Zone” pelvic ring injury and potential concerns that may lead to operative intervention • The learner will understand and become familiarized with the components that various experienced pelvic surgeons use in making the decision between operative and non-operative management • The learner will understand the drivers of poor outcome with pelvic ring disruption and the treating surgeon’s impact on these drivers. Description Case based panel discussion centered on decision making in pelvic ring management. Cases will present diagnostic challenges with regard to operative VS non operative management. Emphasis will be on how and why ‘pelvic experts’ decide on a treatment modality, when is non operative manage-ment appropriate and components of this decision making. Many questions are unanswered with regard to which patients benet from operative intervention of pelvic fractures; in particular those with minimal displacement. Much of the current litera-ture relies on expert opinion although more and more literature is showing acceptible outcomes with non operative management. This session will aim to provide an in depth discussions to how various ‘experts’ make the decision and what factors come into play when deciding operative VS non operative management.

McKee, MD Niloofar Dehghan, MD, MSc Jeremy Hall, MD, MEd Aaron Nauth, MD Peter A. Cole, MD Learning Objectives • How to determine which clavicle fractures and shoulder girdle injuries need surgery • How to optimize xation of shoulder girdle injuries when surgery is indicated • How to manage complications following shoulder girdle surgery Description A primary goal of the symposium will be to achieve consensus opinions on many current issues and controversies regarding the treat-ment of shoulder girdle injuries. The sym-posium will allow registrants to determine which injuries need surgery, optimize xation when surgery is indicated and manage com-plications. There is increasing interest in the management of shoulder girdle injuries. The controversy around indications for operative intervention remains higher than that seen with other fractures and there remains sig-nicant room for improvement in the care of these injuries. Lower Extremity Deformity--How to Evaluate, When to Plate, When to Nail, When to Frame, and When to Give Up Moderator: Brett D. Crist, MD Faculty: Mitchell Bernstein, MD Mark A. Lee, MD Mauricio Kfuri, MD, PhD Rahul Vaidya, MD Learning Objectives • Correctly evaluate lower extremity deformity clinically and radiographically. • Choose the appropriate technique for the location of the deformity through preoperative planning and patient evaluation. • Utilize the appropriate techniques for deformity correction. Description Lower extremity deformity evaluation is important to understand for orthopaedic surgeons managing fractures and for pa-tients seeking arthroplasty--we all see these patients. Choosing the technique that will lead to the most successful outcome is Saturday, October 23, continued 6:30 AM - Concurrent Breakout Sessions (cont’d) 7:30 AM Displaced Intra-Articular Calcaneus Fracture Management from “Soup to Nuts”: When, How, and Getting it Right Moderator: John P. Ketz, MD Faculty: Michael A. Maceroli, MD Roy W. Sanders, MD Mark Gage, MD Learning Objectives • Present a detailed review of surgical technique for both the sinus tarsi and extensile lateral approaches. • Provide an easily reproducible method for deciding the best surgical approach based on timing, patient and fracture characteristics. • Special focus on open, intra-articular calcaneus fractures from soft tissue management and initial xation to denitive surgery. Description Displaced intra-articular calcaneus fractures remain difcult to effectively treat and tend to spur intense debate regarding timing and approaches. The goal of this breakout ses-sion is to provide an overview of calcaneus fracture management, focusing specically on the key techniques that will maximize outcomes. Talks will be case-based and will highlight specic factors that will demystify decisions related to the best surgical ap-proach. Displaced intra-articular calcaneus fractures are complex problems with a very limited margin for error in both technique and decision-making. Errors in management of these fractures can result in signicant dis-ability. Current controversy exists between the sinus tarsi or extensile lateral approach and is a hot topic of debate. The goal of this breakout session is to establish which frac-tures may benet from one approach versus another as well as presenting technical tricks on reduction and xation with a goal of improving outcomes. Treatment strategies for dealing with open fractures will also be discussed as well as having a case based audience participation.

22 #OTA2021 | @otatrauma | @otatrauma | Register Today at ota.org OTA 37th Annual MeetingOctober 20 - 23, 2021 • Fort Worth, TexasSaturday, October 23, continued 6:30 AM - Concurrent Breakout Sessions (cont’d) 7:30 AM challenging. Participants will learn how to evaluate and choose the techniques that will most likely lead to success. Thorough deformity evaluation is often underutilized in orthopaedic trauma. We all see patients with nonunions/malunions/bone loss/leg length discrepancy that present for acute fracture management, delayed management, or in preparation for arthroplasty. We will give the participants the knowledge and tools to cor-rectly evaluate and manage these patients. Dying Controversies in Orthopaedic Trauma… Or Are They? Moderator: Milton T.M. Little, MD Faculty: Marschall B. Berkes, MD Carol Lin, MD, MA Geoffrey Marecek, MD John A. Scolaro, MD Learning Objectives • Discuss literature surrounding paradigm shifts in controversial orthopaedic treatment strategies. • Appreciate the evolution of surgical approaches, techniques, treatment strategies and their impact on outcomes. • Recognize the risks and benets associated with these changing treatment strategies. Description The evolution of orthopaedic trauma is de-pendent on evaluating scientic evidence, rening surgical techniques, and working to improve patient outcomes. While this has led to many advancements in patient care, some historical non-operative treatment techniques have persisted despite their mid-dling success. This breakout examines some fractures commonly treated non-operatively and discusses the shortcomings of non-op-erative treatment and the paradigm shift of the management of these injuries. The breakout will provide a forum to discuss evi-dence to challenge persisting historical sup-port for non-operative treatment of common orthopaedic injuries. Non-operative treat-ment of humeral shaft fractures continues to be touted as the gold standard despite non-union rates that range as high as 17-20%. Non-operative treatment of extra-articular scapula fractures continues despite advanc-es in surgical techniques which can limit approach morbidity and pain associated with malunions. Flail chest continues to lead to prolonged intubation in polytraumatized patients despite growing familiarity with rib plating techniques. Fixation of associated bula fractures with plafond fractures may provide indirect plafond reduction and increased lateral column stability, but the bula is still ignored by many surgeons. Lastly, despite evidence posterior malleolus xation improves syndesmotic reduction and stability, the size of the posterior malleolus is often considered the most determining factor posterior malleolus xation.7:30 AM - Symposium III: 9:00 AM How Can We Fix Racial, Ethnic, and Socioeconomic Healthcare Disparities in Orthopaedics and Do these Disparities Exist in Orthopaedic Trauma?

Despite evi-dence to show disparities in orthopaedics, 91% of surveyed orthopaedic surgeons do not believe that differences in race/ethnicity can adversely affect orthopaedic care1. The OTA’s Diversity committee was created in 2020 with several goals to help improve diversity within the OTA while address-ing ways to improve disparities within our orthopaedic trauma patient population and communities. The OTA diversity committee will dene the problems, discuss effective solutions, and offer insight on how ortho-paedic trauma surgeons can play a role in solving these healthcare disparities. When healthcare disparities exist and such a large percentage of orthopaedic surgeons do not recognize or acknowledge how disparities can adversely affect orthopaedic care, patients and communities suffer. The OTA diversity committee plans to not only review and discuss the issues, but also, offer solutions that will help orthopaedic trauma surgeons, healthcare systems, and communi-ties. 1Adelani MA, O’Connor MI.

Description A primary goal of the symposium will be to achieve consensus opinions on many current issues and controversies regarding the treatment of peri-prosthetic fractures. The symposium will allow registrants to optimize surgical decision making and xation and manage complications following these difcult injuries. Peri-prosthetic fractures are increasing in frequency and complexity as the number of patients with a joint replace-ment, and their activity levels post-surgery, steadily rise. The failure rate of operative intervention remains higher than that seen with other fractures and there remains signicant room for improvement in the care of these injuries.

Sciadini, MD Faculty: Michael A. Maceroli, MD Jason W. Nascone, MD Conor P. Kleweno, MD Brent T. Wise, MD Learning Objectives • Provide a comprehensive review of combined pelvic ring and acetabulum fractures from initial temporization to order of operation and denitive xation. • Discuss the different challenges faced when treating acetabular fractures complicated by both subtle and complex posterior pelvic ring injuries. • Highlight cases that helped shape the “learning curve” and how this has changed our practice. Description The goal of this breakout session is to provide treatment strategies for combined pelvic ring and acetabulum fractures. Presen-tations will be case-based and will compre-hensively review management from initial temporization to strategies for denitive reconstruction. Strategies will focus on the latest decision-making and xation options to maximize outcomes. Combined pelvic ring and acetabulum fractures are extremely difcult and rare injuries that present unique challenges. Due the their relative infrequen-cy, “ring-tabs” have not been a focus of discussion at national meetings or in peer- reviewed literature. That, combined with a steep learning curve, makes treating these injuries all the more difcult. The aim of this breakout session is to provide comprehen-sive strategies for initial management, surgi-cal planning and denitive xation through case-based lectures. Furthermore, the cases shown will highlight the key steps in those that went well and, more importantly, those that left room for improvement. Rotation, Rotation, Rotation: Why is it Important and How To Get it Right in Lower Extremity IM Nailing Moderator: James C. Krieg, MD Faculty: Patrick C. Schottel, MD Michael Blankstein, MD Mark R. Brinker, MD Ida L. Gitajn, MD Learning Objectives • The learner will understand the clinical signicance of femoral and tibial malrotation after IM nailing. • The audience will know the most common methods to intraoperatively assess femoral and tibial rotation as well as how to avoid common pitfalls. • The attendee will be able to perform the appropriate diagnostic work-up and deformity correction of rotational malunion cases. Description Diaphyseal femur and tibia fractures com-monly occur in the setting of high energy trauma. Reamed, statically locked intramed-ullary nail xation is widely accepted as the standard of care in most cases. However, high rates of malrotation have been reported resulting in unacceptable clinical outcomes. The purpose of this session is to review lower extremity diaphyseal malrota-tion following IM nailing with an emphasis on intraoperative prevention and malunion deformity correction. The incidence of femo-ral and tibial malrotation following IM nailing is unacceptably high. A review of the most accurate and reliable methods for assessing intraoperative femur and tibia rotation would benet the attendee to ensure that the most appropriate techniques are being used. Additionally, a discussion of deformity plan-ning and execution is important as the topic is not commonly discussed. This Breakout would serve as an excellent forum to review common pitfalls and how to maximize patient outcomes in regard to restoring lower extremity rotation.

Moderator: Benjamin Ollivere, MD, MA Faculty: Paul Tornetta III, MD Reza Firoozabadi, MD J. Tracy Watson, MD Learning Objectives • Management strategies for complex metadiaphyseal injuries • Understand different approaches to metadiaphyseal injuries current controversies • Understand how to optimise outcomes in complex metadiaphyseal injuries Description Metaphyseal malalignment is among the most common complication in periarticular injuries. This symposium will cover the tech-nical aspects of contemporary techniques in-cluding ‘extreme nailing’, adjunctive plating, nail-plate constructs and circular frame use. Cases will be used for a discussion of the decision making for complex metaphyseal injuries. Malalignment is common in peri-articular injury (5%-25%). These problems can be caused by bad decision making or by technical issues. This session will cover the underlying decision making processes in the key areas of metadiaphyseal trauma to be discussed and understood. The case illustrated discussion session will cover tips and tricks supported by a principles based approach to complex injuries.

Register Today at ota.org 29 Rehab to Optimize Outcomes: Getting Our Patients Back on their Feet Moderator: Daniel J. Stinner, MD, LTC Faculty: William T. Obremskey, MD, MPH Joseph R. Hsu, MD Kristin Archer, PhD Learning Objectives • The audience will understand the typical norms for time to weight bearing follow- ing injuries to the lower extremity. They will also learn about current data where these norms have been challenged to optimize outcome. • The audience will understand the impact that psychosocial factors have on outcome. They will also be instructed on methods to identify patients at higher risk for poor outcome and methods for intervening early to optimize outcome. • The audience will learn about various bracing options that can improve outcome (pain and function) in patients following foot and ankle trauma. They will also learn about several adjunct treatment therapies and the data to support or discount their use. Description This breakout will use evidence to challenge the current standards of rehabilitation following extremity trauma and will provide guidance on incorporating it into clinical practice. From recommendations on early weight bearing to bracing and blood ow restrictive training, this breakout will pro-vide evidence-based tips on rehabilitation to help optimize the outcomes of patients following extremity trauma. Little emphasis is placed on our patients after they leave the operating room and we know that not all patients are created equally. This breakout will 1) help the orthopaedic surgeon identify patients who may be at risk for a worse out-come and 2) provide them with the tools to optimize their recovery well after they have left the operating room. Axial Plane Deformity - How to Avoid It and Correct It Moderator: Geoffrey Marecek, MD Faculty: Milton T.M.

Maceroli, MD Faculty: Cory A. Collinge, MD Sandeep Soin, MD John P. Ketz, MD Roberto C. Hernandez-Irizarry, MD Learning Objectives • Take away strategies for reduction and xation of extra-articular tibia fractures with specic focus on anatomic regions and the unique challenges each presents. • Addressing the combined tibia shaft fracture with intra-articular involvement while maximizing quality of reduction and minimizing soft tissue disruption. • What to do When it Doesn’t Work --- strategies for managing tibial nonunions and bone loss with and without concomitant infection. Description The goal of this breakout session is to pro-vide an in-depth look at tibia fracture man-agement separated by “anatomic thirds”, highlighting specic challenges and tech-niques for each. Presentations will be case-based (with literature support) and include everything from surgical planning to implant selection to reduction techniques. Strate-gies will focus on the latest decision-making and xation options to maximize outcomes. Tibia fractures remain one of the most common injuries treated in tertiary referral and community trauma centers alike. Most educational items discuss “tibia fractures” as a whole despite sometimes stark differences in treatment strategy depending on fracture location and morphology. This breakout session will aim to unpack tibia fractures into anatomic regions, allowing for a more de-tailed discussed of the specic skills required to achieve reduction and promote healing in each location. In addition, a special focus will placed on tibial shaft fractures with con-comitant intra-articular components as well as those with diaphyseal bone loss.

#OTA2021 | @otatrauma | @otatrauma | Register Today at ota.org 30 Saturday, October 23, continued 2:12 PM - Concurrent Breakout Sessions3:12 PM Description Axial plane deformity is fairly common after fracture. This symposium will highlight strategies to avoid malrotation and short-ening. We will discuss how to evaluate and treat patients with deformity. Axial plane deformity is a common source of litigation. New evidence suggests that neither length nor rotation are symmetric. Newer treatment modalities make correction of small deformi-ties feasible. Contaminated Open Fractures: Getting It Right and What to Do If It Goes Wrong Moderator: Benjamin Ollivere, MD, MA Faculty: Paul Tornetta III, MD William M. Ricci, MD J. Tracy Watson, MD Learning Objectives • Management strategies for open-articular fractures. • Dealing with post-operative infection. • Reconstruction options in segmental defects. Description The contaminated open fracture is the most devastating of orthopaedic injuries. Man-agement issues to be addressed include all aspects of management of contaminated open fractures and management of initial soft tissue and contaminated bone manage-ment, secondary infection and strategies for management of joint and diaphyseal bone loss including transport and lengthening nails. The contaminated open fracture pres-ents to every area of orthopaedic practice. There have been improvements in standards of care, reconstructive options and expected outcomes. This session will cover the under-lying decision making processes in the key areas of contaminated open fracture man-agement to be discussed and understood. The case illustrated discussion session will cover tips and tricks supported by a princi-ples based approach to complex injuries.
