Through a combination of lecture, expert panels and small group discussions, this workshop will equip orthopaedic surgeons and advanced practice providers with the skills and knowledge to reduce medical and surgical complications, improve hospital-level outcomes such as length of stay and readmission, and strategies on how to implement a fracture liaison service within your health care system.Effective Leadership Skills for Every Orthopaedic Trauma Surgeon 8:00 AM – 12:00 PMSurgeonMastersEarly in our careers, most of us are focused on being technically skilled enough and smart enough to handle any challenging patient case. However, most careers get frustrated by the challenges outside the operating room. Every orthopaedic trauma surgeon is a leader, even if they don’t aspire to be the director, chairman, or to serve another administrative leadership role. This pre-meeting event will address leadership skills that every orthopeadic trauma surgeon should develop to increase their career success.Women Orthopaedic Trauma Surgeons Forum 1:00 PM – 5:00 PMWoman Surgeons of Orthopaedic Trauma AssociationA forum for women trauma surgeons to network, and discuss issues that affect them as women and orthopaedic trauma surgeons. Such as how to succeed in a male dominated specialty, navigate pregnancy and maternity, how to succeed in research, surgical tips and tricks etc. This event is intended for women surgeons, fellows and residents. Upper Limb Trauma Association (ULTrA) 1:00 PM – 5:00 PMThis is a working group for those with a particular interest/expertise in upper extremity trauma. More and more centers have surgeons who sub-specialize in upper extremity trauma, and this is a group focusing on these injuries. We will focus on collaborative research projects, discuss unique problems encountered in the upper extremity, and share techniques and advice to help mentor younger surgeons.Planning Committee Jacqueline J. Krumrey, MDToni M. McLaurin, MDOTA HIGH SCHOOL SCHOLARS PROGRAM Catherine A. Humphrey, MD Milton Little, MD Emily Benson, MDThis program was launched in 2022 and due to its success as a rst-time event and OTA’s high value for diversity, equity, and inclusion it is OTA’s desire to offer the Orthopaedic Trauma Association High School Scholars Program to run concurrently with the OTA Annual Meeting each year.OTA recognizes despite the growing diversity of the US population; orthopaedic surgery has remained one of the least diverse surgical subspecialities in medicine. The slow increase in underrepresented minority (URM) senior faculty reects the lack of underrepresented orthopaedic residents. Many barriers to URM students seeking careers in orthopaedic surgery include lack of exposure, in-home obstacles, high school peer pressure, lack of URM role models and even negative stereotyping of URM students at all educational levels. The OTA Diversity High School Scholars Program provides a pipeline that will provide early orthopaedic exposure with a goal of increasing diversity in orthopaedic surgery.The course will be a half day program which includes an ice breaker, career panel, and hands-on experience where students will experience casting, x-ray interpretation, orthopaedic hardware placement and ex-x.

Distal femur fractures remain complex, challeng-ing injuries with relatively high failure rates. Though modern pre contoured lateral locking plates have historically been the mainstay of surgical treatment for distal femur fractures, the use of intramedullary xation and dual constructs including nail/plate combinations and dual plates have become increasingly popular. The indications for single constructs versus dual constructs remains unclear, and ways to optimize the application of these implants have not yet been fully elucidated. The purpose of this breakout session is to address the problems that currently exist with distal femur frac-ture xation, and utilize an evidence-based approach to identify problematic fracture pattens and patient comorbidities.9:35 AM - Surgical Considerations in Obese10:35 AM Patients: A Focus on Tactics and Techniques Moderator: Malcolm R.

With the rising prevalence of obesity nationally and globally, surgeons are called to evolve their practices to accommodate larger patients with skill and tact. Using case-based discussions with expert faculty, this session will focus on specic technical considerations to promote optimal outcomes after surgical xation of pelvic ring injuries, acetabulum, distal femur, tibial plateau, and pilon fractures in larger patients. A particular emphasis will be made on positioning, exposure, reduction and x-ation strategies for obese patients with these complex injuries.9:35 AM - When All Hope is Lost, How to10:35 AM Salvage the Unsalvageable, Part II Moderator: Jonah Hebert-Davies, MD Faculty: Conor P.

Miller, MD, FIOTA Faculty: Sarah Hendrickson, MEd Ben Ollivere, MD Daniel Stinner, MD Heather A. Vallier, MD, FIOTA Philip Wolinsky, MDLearning Objectives• Develop strategies to educate, engage and em-power patients and providers regarding mental and social health needs and resources during recovery from injury.• Assess existing supporting research and develop directions for future work.• Implement programs to foster resilience during recovery. Resource acquisition and advocacy will be discussed.DescriptionThis symposium will address mental health and social issues associated with slowing and/or preventing full recovery after MS injuries. Factors important to devel-oping resilience and to promote successful recovery will be described. Supporting research will be sum-marized. Potential strategies for the implementation of patient-centered programs and nancing will be presented. Most orthopedic surgeons have limited education and training regarding mental and social health opportunities, effective communication and relationship-building strategies, and navigating the current health environment that deprioritizes mental health care issues. The potential roles of advocacy and partnership to access mental health resources for our patients will be explored.2:00 PM - CONCURRENT3:00 PM BREAKOUT SESSIONS Combined Pelvic Ring and Acetabulum Fractures: What I’ve Learned and What I Wish I Would Have Known Back Then Moderator: Michael Maceroli, MD Faculty: Jason Nascone, MD Brent Wise, MD Conor P. Kleweno, MD Marcus Sciadini, MDLearning Objectives• Provide a comprehensive review of combined pelvic ring and acetabulum fractures from initial temporiza-tion 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.DescriptionThe goal of this breakout session is to provide treat-ment strategies for combined pelvic ring and acetab-ulum fractures. Presentations will be case-based and will comprehensively 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 infrequency, “ring-tabs” have not been a focus of discussion at national meetings or in peer-reviewed literature. That, com-bined with a steep learning curve, makes treating these injuries all the more difcult. The aim of this breakout session is to provide comprehensive strategies for initial management, surgical 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.

Donegan, MD, MBA Faculty: Matthew R. Garner, MD Mark R. Adams, MD Lisa Blackrick, MD, MS Tim G. Weber, MD Milton L. Routt, MD Milton T.M. Little, MDLearning Objectives• Describe a comprehensive worldview and healthy lifestyle habits.• Describe how difculties at home can affect work and vice versa.• Describe how to process and respond to personal and professional difculties.DescriptionInvariably, the recent suicides of our friends and col-leagues come up in conversation whenever we are so-cializing with other orthopaedic trauma surgeons. This speaks to a growing awareness of an existential prob-lem in our midst. These suicides illustrate how difcult life can be within this profession. These difculties exist at home and at work, and the two can be interconnect-ed. It is difcult to struggle with a personal problem and still perform at a high level at work, and vice versa. In these smaller social gatherings, we share our strug-gles and our responses. We also discuss our larger outlook, our lifestyles, and our strategies towards living in a full and healthy way. This is uplifting and therapeu-tic for all involved. We would like to bring these conver-sations to a larger audience to stimulate thought and discussion amongst a larger group.2:00 PM - Treatment of Upper Extremity3:00 PM Periprosthetic Fracture - Tips and Tricks for the Trauma Surgeon Moderator: Niloofar Dehghan, MD, MSc Faculty: Kenneth A. Egol, MD Michael D. McKee, MD Ben Ollivere, MD Niloofar Dehghan, MD, MScLearning Objectives• Identify when non-operative treatment is appropri-ate, and when is surgery indicated. Which fractures should a trauma surgeon be able to manage, and which need revision arthroplasty.• Appraise humeral shaft periprosthetic fractures - technical aspects of surgical xation to obtain the best outcomes.• Understand scapula and acromion fractures in the setting of reverse shoulder arthroplasty - They need surgery, but how to achieve union.DescriptionThe prevalence of upper extremity periprosthetic fracture is increasing signicantly. While trauma sur-geons are well trained and comfortable with treatment of lower extremity periprosthetic fractures, for some, fractures of the upper extremity remain elusive. We believe a trauma surgeon should have the appropriate knowledge and expertise to treat fractures of the upper extremity, such as periprosthetic fractures around a shoulder or elbow prosthesis, or acromion stress frac-tures associated with reverse shoulder arthroplasty. While there is a lot of emphasis on lower extremity periprosthetic fractures at trauma meetings and the OTA, educational sessions on upper extremity periprosthetic fractures have been decient. We believe this is an area of trauma that trauma surgeons should be able to manage, and not defer to the “shoulder” surgeons. We believe the lack of educational sessions may be the reason why some trauma surgeons are not comfortable with managing these injuries, and their opportunity to improve this knowledge gap. This breakout session discusses how to best treat these difcult injuries for optimal outcomes: when is non-operative treatment is appropriate, which should be treated surgically, as well as technical aspects of how to perform the surgical procedures.2:00 PM - New Techniques in the Management of3:00 PM Periprosthetic Distal Femur Fractures Moderator: Eben Carroll, MD Faculty: Mark A. Lee, MD Brett D. Crist, MD Matt L. Graves, MDLearning Objectives• Identify the current issues, challenges and common complications seen when managing distal femur periprosthetic fractures.• Highlight to the participant the potential benets and drawbacks to dual implant constructs including the strengths and weaknesses of plate-plate combinations.• Offer technical tips and emerging techniques to achieve success in managing this difcult clinical problem.DescriptionIn this breakout we will review the current problems the clinician faces with management of periprosthetic distal femur fractures utilizing a literature based ap-proach. These issues include nonunion, malunion and inability to mobilize this at risk population in the early post-operative phase. We will discuss emerging tech-niques and technologies that may mitigate some of these issues. We will use a case based approach with a combination of didactic and audience participation (continued next page)

Cannada, MD Faculty: William T. Obremskey, MD, MPH, FIOTA Seth R. Yarboro, MD Kyle T. Judd, MD Lisa K. Cannada, MDLearning Objectives• Understand solutions for failed syndesmosis xation.• Describe techniques for repairing loss of xation or nonunions of ankle fracture.• Managing ankle fractures in physiologically chal-lenged patients.DescriptionThe incidence of ankle fractures is approximately 187 fractures per 100,000 people each year.Ankle fractures have a relatively low complication rate when managed appropriately in patients without co-morbidities. Complication rates in patients with comor-bidities increase and can lead to devastating outcomes. Delayed complications may occur after initial treatment or as a result of treatment. It is important to recognize and understand the complications which can occur and learn strategies for management of these complex problems.2:00 PM - Contemporary Strategies for3:00 PM Bone Defects Moderator: Geoffrey S.

Moderator: Reza Firoozabadi, MD, MA Faculty: Prism Schneider, MD, PhD John A. Scolaro, MD, MA Malcolm R. DeBaun, MD Robert V. O’Toole, MD Yelena Bogdan, MD Reza Firoozabadi, MD, MALearning Objectives• Determine what is the most appropriate pharmaco-logic agent to use to prevent a venous thromboem-bolic event in the orthopaedic trauma patient.• Assess different non-pharmacologic /mechanical forms of prophylaxis and to determine if they are indicated to prevent a venous thromboembolic event in the orthopaedic trauma patient.• Determine the role of thrombelastography and newer pharmacologic agents in the prevention of venous thromboembolic events.DescriptionDVT prophylaxis has always been an important topic in the eld of orthopaedic trauma. A number of high quality studies have come out over the past three years that pertain to this topic and no general consensus has yet to be made in a number of areas. This has result-ed in gaps and in certain cases potential changes to the standard of care that need to be addressed. The purpose of this symposia is to address some of these gaps and to educate the membership on what is most appropriate based on the available high quality data. Five areas of discussion that will be targeted by this di-verse group of presenters will be; 1) The use of Aspirin versus Enoxaparin sodium for VTE prevention, 2) Does new data support the additional use of non-pharmalog-ic/mechanical (compression stockings/SCD’s) to prevent DVT’s 3) Should we be using thrombelastography to identify hypercoagulability in patients with orthopeadic trauma related injuries, 4) What is the most appropri-ate management for patients with different VTE events (proximal versus distal clots). Do all PE’s need full an-ticoagulation? 5) What are newer pharmalogic agents that are being used for DVT prophylaxis? Does any of the data support using them?9:00 AM - 9:40 AM JOHN BORDER MEMORIAL LECTURER How You Can Change the World Robert A.

O’Toole, MD Faculty: Lily R. Mundy, MD Jason M. Souza, MD David Potter, MDLearning Objectives• Understand indications for soft tissue reconstruction using the hierarchy of reconstructive needs.• Summarize current evidence supporting decision- making in optimizing soft tissue reconstruction.• Identify strategies an orthopaedic traumatologist can employ for successful local and regional soft tissue reconstruction.DescriptionExtremity fractures with concomitant soft-tissue injuries can be extremely challenging to manage. Successful soft-tissue reconstruction is essential to achieve an infection-free bony union and often requires multi-dis-ciplinary collaboration. However, there is variability in readily available soft tissue surgeons, especially those with microvascular training and an understanding of complete limb care. This makes it essential for the or-thopaedic trauma surgeon to be well educated in soft tissue reconstruction, so that they may direct manage-ment of the limb.In this breakout session we will discuss ap selection and indications for reconstruction using the hierarchy of reconstructive needs, a principles-based approach to planning soft-tissue coverage. We will summarize current literature on the latest advances in soft tissue reconstruction of the lower extremity, including timing of coverage, ap selection, the impact on post-opera-tive protocols and rehabilitation, and contraindications for limb-salvage. Lastly, we will provide strategies for local and regional soft tissue reconstruction that may be utilized by orthopaedic traumatologists in areas with limited access to soft tissue surgeons.11:35 AM - Infection Treatment: 12:35 PM Emerging Techniques and Evidence Moderator: Paul E. Matuszewski, MD Faculty: Joseph R. Hsu, MD Stephen M. Quinnan, MD Janet D. Conway, MDLearning Objectives• Identify short comings in current strategies to treat infection.• Learn about emerging techniques and strategies to improve patient care and eradication of infection.• Understand the role of emerging techniques com-bined with traditional techniques in your practice.DescriptionCurrent practice of fracture related infection is ever evolving. The socioeconomic cost of treating infec-tions is high and both burdensome to the patient and society. New and updated techniques are emerging as potential methods to decrease that cost, including single-stage surgeries, antibiotic coated implants, biologics and injectable technologies. The purpose of this breakout is to provide the surgeon with the most up-to-date techniques and evidence to help guide their treatment of fracture related infections.11:35 AM - Not Just a Femoral Neck Fracture: 12:35 PM What to Do in the Young Patient Moderator: Paul Tornetta III, MD, PhD, FIOTA Faculty: Ben Ollivere, MD Saam Morshed, MD, PhD, MPH Cory A. Collinge, MD Paul Tornetta III, MD, PhD, FIOTALearning Objectives• Understand the current literature surrounding tim-ings for, and interventions in young femoral neck fractures.• Improve decision making in young femoral neck fractures and understand controversies in treatment.• Consider management of complications and strate-gies to minimize those.DescriptionProximal femoral fractures in young patients account for around 10% of hip fractures and require different treatment strategies. The young, often high energy, femoral neck fracture presents a uniquely difcult scenario to the orthopae-dic traumatologist. Rapid diagnosis and appropriate early treatment whilst minimizing complications is the goal. This breakout will cover contemporary evidence and unpick controversies surrounding timings for and treatment strategies. Minimization of complications and tips and tricks for difcult xations along with the best strategies for dealing with complications. The discussion and debate nature of this session will allow the underlying decision making processes in the key areas of young femoral neck fractures to be dis-cussed and understood. Critical steps in achieving a good outcome will be focus of this breakout session.

Moderator: Reza Firoozabadi, MD, MA Faculty: Paul Tornetta III, MD, PhD, FIOTA Kelly A. Lefaivre, MD H. Claude Sagi, MD Milton L. Routt, MD Conor P. Kleweno, MDLearning Objectives• Determine how much anterior and/or posterior xation is required to maintain a reduction of specic pelvic ring injury patterns.• Identify how to treat sacral non-unions with broken hardware.• Describe when a relatively benign pelvic ring injury can signicantly displace over time and how to treat it once you have signicant deformity.DescriptionThe purpose of this breakout session to provide healthy discussion around the topic of pelvic ring injuries that went bad. This will be a case-based discussion review-ing failed non-operative and operative management of pelvic ring injuries. The discussion will be centered around the following; what could have been done differently at the index procedure, potential reasons for failure, and how to address pelvic ring deformity post-surgery. Anterior and posterior pelvic ring xation options will be examined in the setting of a non-union/mal-union surgery. Open versus percutaneous posterior ring injury xation will be discussed in addition to when is lumbopelvic xation required. Further consideration will occur in regards to bone grafting and using auto versus allo vs BMP for the sacral nonunion. Techniques for removal of broken transiliac transacral screw will be reviewed and utility of c-clamp for reduction assistance will be debated. Lastly, we will discuss postoperative course and weightbearing restrictions and does weight-bearing change with type of implants used anteriorly and posteriorly.4:30 PM - High Energy Shoulder5:30 PM and Chest Trauma Moderator: Ben Ollivere, MD Faculty: Andrew D. Duckworth, MSc, PhD Niloofar Dehghan, MD, MSc Michael D. McKee, MDLearning Objectives• Apply management strategies for complex shoulder girdle and chest injuries.• Understand when and how to intervene to maximise outcomes.• Improve decision making in difcult decision making.PRELIMINARY PROGRAM - FRIDAY, OCTOBER 20DescriptionHigh energy shoulder girdle injuries are an area of controversy. Increasingly the shoulder girdle and chest are being seen as single functional unit with complex injuries requiring clear decision making. This breakout will address when and how to operate on injuries to the chest wall, scapula, ACJ and high energy clavicular injuries. Focusing on use of contemporary techniques management and rehabilitation strategies focusing on controversies and points for debate. There is a rapidly changing practice in shoulder girdle and chest trauma. As outcomes from surgical chest wall stabilization, ACJ injuries and clavicle fractures are being tested in randomized trials there is emerging evidence to support decision making in these complex injuries.The discussion and debate nature of this session will allow the underlying evidence basis for 4 common and difcult injuries to be addressed and understood. The session will focus decision making processes in the key areas and be followed by a case illustrated discussion session to cover tips and tricks supported by a princi-ples based approach to complex injuries.4:30 PM - Innovative Approaches to Prevent 5:30 PM and Treat Fracture Related Infection Moderator: Robert V. O’Toole, MD James Doub, MD Faculty: Leah Gitajn, MD, MS Emily Ann McClure, PhD, MS Roman M. Natoli, MD, PhD Jonathan T. Elliott, PhD James Doub, MDLearning Objectives• Provide the orthopaedic trauma community with an overview of promising emerging strategies designed to prevent and treat infection which are likely to be translated into clinical practice in the near-term.• Provide the orthopaedic trauma community with an overview of promising novel strategies designed to prevent and treat infection which may be ready for translation into clinical practice in the medium-term.• Discuss potential barriers and expected impact of these treatment strategies on the eld of orthopae-dic trauma.DescriptionThere are multiple innovative emerging and novel inter-ventions to prevent, diagnose, and treat Fracture Relat-ed Infection which have the potential to revolutionize how we care for patients. However, at the present, the broad orthopaedic trauma community has had minimal exposure to these new approaches. The aim of this proposal is to outline emerging and novel strategies(continued next page)

32 #OTA2023 | @otatrauma | @otatrauma | ota.org PRELIMINARY PROGRAM - FRIDAY, OCTOBER 204:30 PM - CONCURRENT5:30 PM BREAKOUT SESSIONS, continued Innovative Approaches to Prevent and Treat Fracture Related Infection, continuedwhich are likely to impact treatment strategies in the near- and medium-term.Infection after high-energy open fracture is one of the most challenging and common complications facing trauma patients and their orthopaedic surgeons with an estimated annual cost of $35 billion in the US. Infection requires unplanned surgical procedures and leads to prolonged morbidity, loss of function and potential loss of limb. The treatment of patients with open fracture involves IV abx and operative debridement just as it did 50 years ago. Despite universal application of these in-terventions, the rate of infection remains unacceptably high for the past 20 years for the most severe open fractures at approximately 30%. This session is aimed at addressing new techniques to address this unsolved problem.4:30 PM - Cultivating Courage for a Sustainable5:30 PM Surgical Career Moderator: Jeffrey M. Smith, MD, PCC Faculty: Robert Ostrum, MD Carla S. Smith, MD David Elaimy, MALearning Objectives• Learn how courage is a skill to be cultivated in the performance of surgery, advancing in one’s career, and in sustaining oneself through adversity.• Understand critical components of cultivating, maintaining, and restoring courage throughout one’s career.• Assess your current state of managing fear and anxiety to navigate risk for optimal performance and success.DescriptionSurgeons are already considered courageous for getting into medical school, completing a competitive residency, and working in a demanding career.Surgeons nd themselves in some of the most intense situations that demand the highest performance of themselves and others. Despite our intelligence, train-ing, resilience and best intentions, the outcomes can lead to fear, timidity, conformity, and other responses that can impact growth and peak performance. There-fore, courage needs to be cultivated, maintained and, at times, restored.Our discussion will cover many areas that require cour-age to create a sustainable career as a surgeon, in-cluding skill building and working beyond our comfort zone to grow, addressing negative feedback external or internal that can create thoughts as an imposter, perfor-mance under pressure that is critical to patient out-comes and our health, and addressing challenges from our leaders or to our own leadership. Get to the “nish line of retirement” in good shape, not burned out.4:30 PM - Distal Tibia Fractures: Optimizing5:30 PM Stability and Minimizing Complications Moderator: Marschall Berkes, MD Faculty: Milton T.M. Little, MD David Forsh, MD Clay A. Spitler, MDLearning Objectives• Highlight through case based discussion which distal tibia fracture patterns are more amenable to nail xation or plate xation (or both).• Provide tips and tricks for application of distal tibia “extreme nailing”.• Understand when atypical surgical approaches or implants may be required for operative management of distal tibia fractures.DescriptionFractures of the distal tibia, whether extra-articular or with articular involvement present opportunities for choice in surgical or nonsurgical management. This breakout session, through strict case based discussion, will review injury patterns that may be best served through intra-and extramedullary xation and provide guidance on choice of reduction strategy and implant application. Emphasis will be placed on “extreme nailing” with or without adjunct xation with specic case examples to be used as a platform to highlight tips for successful application and avoidance of intra and postoperative complications. Finally, cases will be presented that will inform the audience of nonstandard surgical approaches and implant choice when the situa-tion dictates for injuries to the distal tibia and bula.

Gage, MD Faculty: Edward Ryan Westrick, MD Jonah Hebert-Davies, MD Chris Klifto, MDLearning Objectives• Review evidence-based surgical indications for proximal humerus fractures in the geriatric patient.• Provide tips and techniques for successful fracture reconstruction and shoulder arthroplasty for the proximal humerus fracture patient.• Develop strategies to manage fracture malunion, failed fracture xation and complications associated with shoulder arthroplasty performed for fracture.DescriptionWith an increasingly active and aging population, the prevalence of complex proximal humerus injuries has continued to rise. Although many of these fractures can be managed non-operatively, there is a growing subset of patients who may benet from surgical management or have developed complications related to previous surgical treatment. This breakout session will provide an evidence-based update on surgical indications for these injuries and also discuss modern techniques for fracture reconstruction, shoulder arthroplasty, and man-agement of the surgical complications associated with these treatments.5:30 PM - MILITARY RECEPTION6:30 PM PRELIMINARY PROGRAM - FRIDAY, OCTOBER 205:30 PM - SUDS N’ SCIENCE 6:10 PM POSTER TOURS Foot, Ankle, Pilon Samir Mehta, MD International Ben Ollivere, MD 6:00 PM - KATHY CRAMER MEMORIAL 7:00 PM WOMEN IN TRAUMA RECEPTION

A Comprehensive Review of Evidence Based Norms and Beyond Moderator: Lucas M. Marchand, MD Faculty: Patrick J. Kellam, MD Lucas M. Marchand, MD Stephen J. Warner, MD, PHD Robert V. O’Toole, MDLearning Objectives• Review current evidence-based topics with level 1 evidence in orthopaedic trauma.• Identify current practices by orthopaedic trauma surgeons in peri-operative management of orthopaedic trauma patients.• Understand the baseline rate of each practice in order to track the changes in practice overtime.DescriptionThis symposium would start with a comprehensive review of the current accepted evidence-based top-ics with level 1 evidence. The focus would then be on controversial topics that are common in orthopaedic trauma to assess what the current practice norms are for OTA attendees. Questions will focus mostly on top-ics that are currently either being actively debated (e.g lateral versus prone for Kocher-Langenbeck approach to the acetabulum) or potentially changing (e.g tight-rope versus screw xation for syndesmotic xation). It is helpful for surgeons to be able to see how their colleagues are addressing controversial topics in the eld that they practice; and, this symposium would provide the opportunity on a larger scale for the OTA community to understand the current trends. The goal of this symposium would be to determine the current practice norms for orthopaedic trauma sur-geons currently practicing regarding these topics. The hope would be to have this symposium biennially so trends and shifts can be identied and tracked through-out time.9:00 AM - GUEST NATION – HIP FRACTURE CARE9:20 AM Spain: Hip Fracture Care in Spain9:20 AM - WELLNESS UPDATE9:30 AM 9:30 AM - Break9:45 AM9:45 AM - PODIUM SESSION VII:10:50 AM Upper Extermity Moderators: Andrew M.

Many historical treatments resulted in failure secondary to incomplete under-standing of the various types of injuries that exist. In this symposium, we will review the multiple different types of elbow fracture-dislocations, with the intention of providing the participant with the tools needed to make an accurate diagnosis of the injury as well as formulate a surgical tactic for its repair. As these injuries are relatively uncommon, they are usually referred to high-volume trauma centers with particular expertise in their management. The symposium faculty are ac-complished trauma surgeons with an expertise in the treatment of complex elbow injuries, and will present pearls and pitfalls for the treatment of the various types of periarticular elbow fracture-dislocations.

Indications and timing for arthroplasty in geriatric acetabular frac-tures will be also be highlighted for participants.As our population continues to age, the prevalence of geriatric acetabulum injuries has increased. Although many of these injuries can be managed non-operative-ly, the subset who require operative xation present unique challenges such as osteoporotic bone, narrow bony corridors and pre-existing arthritis. Furthermore, unlike younger populations, early mobility in the geri-atric patient is paramount to preventing catastrophic physiologic complications. This breakout session pro-vides tips/tricks to efciently and effectively treat these injuries.10:55 AM - PODIUM SESSION VIII:12:00 PM Thromboprophylaxis and Tibia Moderators: Mark A.
