We are excited to welcome you to our hybrid edition of the Global Spine Congress (GSC). Following a successful in-person congress in 2021, we are back together again, allowing our surgeons to network and engage with experts in their field.

We welcome you in-person, while at the same time connecting with our online community who are joining us from around the world.

The GSC is the perfect meeting place for a highly connected group of leaders in the field of spine care. It provides an outstanding forum to exchange ideas, network with fellow spine professionals, and learn the latest research, techniques, and technologies in spine surgery.

The GSC is the most important academic meeting, as well as one of the biggest

gatherings of the global spine community. The GSC takes place at the Mandalay Bay, North Convention Center, located at the south end of the Las Vegas strip, giving a whole new meaning to grand Las Vegas events.

Back by popular demand, GSC 2022 will be a hybrid event, featuring an additional range of online presentations and activities alongside the onsite congress.

The GSC brings together industry, surgeons, and healthcare providers to capitalize on experiences and success stories. This event offers both networking and educational opportunities to the global community.

We hope that during your stay in Las Vegas you will have an opportunity to explore the city, and enjoy world famous entertainment, shopping, and fine dining.

Debates—it's your callThis year, we are introducing a new feature: Debates. Taking place on Thursday, June 2 during the exhibition opening, two debates will each pitch two speakers offering opposing views on a particular topic. It will be up to you to decide on which is the better option and cast your vote— it promises to be thought-provoking, engaging, and also a little bit of fun. Moderated by Jeffrey C. Wang, the two debates are:

Surgical treatment for sacral insufficiency

fractures—how minimal-invasive can

one be?

AO Spine Members-Only SessionsHow to brand yourself/social media and branding: Academic vs private practice (Room 1)Moderator: Norman ChutkanSpeakers: Lali Sekhon, Yong Hai, Ahmet AlanayWednesday, June 1, 17:00–17:45Over 1 billion names are googled every single day. As a surgeon it's very likely someone has looked you up. What people find out about you online and offline determines how you are perceived by patients and business partners. In this session you will learn tips and tricks about how to brand yourself. The Future of Medical Education (Room 2)Moderator: Emre AcaroğluSpeakers: Urs Ruetschi, Jane Wiedler, Emre Acaroğlu, Bryan AshmanWednesday, June 1, 17:00–17:45This one-hour session will educate the audience on how medical education is changing and how AO Spine is constantly evolving to fulfil the needs of its learners, both online and face-to-face.

The aging spine surgeon: when is it time to transition your career? (Room 3)Moderator: R. Kiran AlluriSpeakers: S. Rajasekaran, Luiz Vialle, Jens ChapmanWednesday, June 1, 17:00–17:45The average physician retirement age is typically older than the general population, and part of this simply boils down to job satisfaction—or many doctors, practicing medicine is a passion rather than just a career, and the relationships they’ve developed over the years while building up their practice and their patient books are what keep them motivated to continue. Other reasons for late retirement could be financial obligations coming from the additional years of schooling required for a medical career or from the flexibility available for physicians to gradually reduce their workload in the years leading up to full retirement.

Leadership Skills (Room 1)Moderator: Juan EmmerichSpeakers: Asdrubal Falavigna, S. Rajasekaran, Jeffrey C. WangWednesday, June 1, 17:45–18:30This session will focus on key leadership skills and how they are developed and implemented, through an interactive panel discussion format. The KOLs will share their experiences and lessons learned.

KF Degenerative Lessons Learned—Evidence Surrounding Patient Reported Outcomes, what do they mean? (Room 2)Moderator: Zorica BuserSpeakers: Nancy Santesso, Stipe Corluka, Zorica Buser, Timothy S. YoonWednesday, June 1, 17:45–18:30This symposium will be in a debate format and would involve audience participation. Various Patient Reported Outcomes have been used to predict the success of surgery and patient’s recovery. While they have been extensively used, there is no standardization to which PROs are a must and which are reliable. In addition, information on how PROs translate between different outcomes and the case complexity is unknown. Our KF has worked to better understand the clinical impact of PROs on treatment decision making through the AOGO recommendation initiative, and the DegenPro registry.

The Good, The Bad And The Ugly—The Case That Taught Me The Most (Room 3)Moderator: Emre AcaroğluSpeakers: Richard Bransford, Luiz Gustavo Dal Oglio Da Rocha, Abhay NeneWednesday, June 1, 17:45–18:30Discuss challenging cases with highly experienced surgeons and gain insight into potential complications experienced during surgery.

About the AO Foundation and AO Spine

The AO FoundationThe AO Foundation is a medically-guided, not-for-profit organization, a global network of surgeons, and the world’s leading educational and research organization for the surgical treatment of trauma and musculoskeletal disorders. It was established as the Arbeitsgemeinschaft für Osteosynthesefragen (Association for the Study of Internal Fixation) in 1958 by a group of Swiss surgeons who shared one goal—delivering radically improved patient outcomes in the treatment of trauma and musculoskeletal disorders. They worked with an engineer to develop a disruptive technology and defied medical convention to introduce their new standardized approach, offering surgeons the tools, techniques, and training they needed, and created a global industry in their wake. Today, the AO has a global network of over 200,000 health care professionals. Each year it offers over 830 educational events around the world, which are supported by nearly 9,000 faculty and are attended by over 58,000 participants. It has over 20,000 surgeon members working in the fields of trauma, spine, craniomaxillofacial (CMF), veterinary, and reconstructive surgery. AO education is recognized as the gold standard in these fields, and to date more than 600,000 health care professionals in over 124 countries have participated in AO courses. Headquartered in Davos, Switzerland, the AO has 330 employees and each year invests over 100 million CHF into research, development, and education to improve patient care worldwide.

AO SpineAO Spine is a professional medical association of spine surgeons and a clinical division of the AO Foundation. AO Spine is the leading global academic community of spine surgeons dedicated to generating, distributing, and sharing knowledge through research, education and community development.Established in June 2003, the organization is led by the AO Spine International Board. The board guides and supports the AO Spine regions Asia Pacific, Europe and Africa, Latin America, Middle East, and North America. Each region drives more than 150 local educational activities within the AO Spine international network. Today, AO Spine fosters a global community of 30,000 members and associates from all over the world.
