AO Technical Commission Experts Symposia

The Experts Symposia of the AO Technical Commission (AO TC) are well-established events to foster exchange among surgeons and representatives of our industrial partners with the overall goal to improve patient treatment. It is essential to review the clinical performance of implants, instruments, and the surgical techniques. Open and straightforward discussions are fundamental for identifying potential device improvements and refinements of surgical procedures. Consequently, the symposium format is fundamental in fulfilling the AO TC quality assurance mandate for newly developed devices when they become available for surgeons. The symposia have proven to be invaluable for defining the remaining unmet clinical need that is not yet addressed by existing solutions. This type of information is imperative to justify the initiation of new development projects, which makes the Experts Symposia highly appealing to our industrial partners. The information exchange at the symposia is strictly confidential.

The experiences over the past few years have reinforced the benefits of inviting experienced surgeons of all age groups to the symposia. While the more senior surgeons are familiar with the development history of implants and instruments as they became available, younger surgeons may be more apt to think out of the box. Since the initiation of the AO TC Experts Symposia in 2006 about 920 surgeons have participated and consequently, this AO TC network is rapidly expanding.

After a COVID-related break, the European Symposium took place outside of Germany for the first time. 57 surgeons from 21 countries attended the 15th European edition of the AO TC Trauma Experts Symposium on August 26–27, 2022. The event occurred in Oslo, Norway—the first time the symposium was hosted outside of Germany. Chaired by the Past-President of AO Trauma Germany, Michael Raschke, the program was divided into five sessions:

VA-LCP Clavicle Systems
VA Locking Patella Plating System
Periprosthetic Fracture Fixation of Femur
Proximal Tibia Fractures
Double Plating Femur

Each session consisted of an introduction to the subject by one of the faculty, followed by a case discussion using cases submitted by participants, and ended with a conclusion and clinical needs definition by the moderator.

Michael Kowaleski (veterinary) from North Grafton, Massachusetts, US, won the symposium's most interesting case presentation award for delivering a deformity case of a dog which underwent prior high tibial osteotomy (Tibial Plateau Leveling Osteotomy, TPLO).

The 16th AO TC Trauma Experts Symposium (Europe) will be held in August 2023 in Florence, Italy, and it will be chaired again by M Raschke.

The 4th AO TC Trauma Experts Symposium (Latin America) was held on March 6–7, 2020, in Rio de Janeiro, Brazil. It was chaired by P Barbosa and was attended by Twenty-seven Latin American surgeons from 12 countries.

The symposium program covered the following topics:

Infection
Calcaneus fractures
Ankle
Proximal femur in Oestoporotic bone
Nonunion

In the session on proximal femoral fractures, the discussion was mainly about how augmentation in nail fixation can improve clinical results. P Barbosa shared his tips and tricks to facilitate reduction (see also the Meet the Experts Video here).

The winner of the contest for the most interesting case presentation was Emilio Fantin who shared a femoral nonunion case after intramedullary nailing, which he managed by increasing the stability at the nonunion site with an intracortical percutaneous compressive screw.

The 5th AO TC Experts Symposium (Latin America) will take place on May 19-20, 2023 in Bariloche, Argentina.

6th US AOTK Experts Symposium, USA

Every 2 years there is a trauma-related AO TC Experts Symposium in the United States. The Symposium held on September 13-14, 2019, in San Francisco, was chaired by M Lee and was attended by 45 participants.

The symposium program consisted of five sessions:

Complex and atypical plateau fractures: do we need special implants or approaches?

Displaced and unstable femoral neck fractures: is there a length stable implant solution?

Distal femoral fixation: are there new solutions or needs?

Syndesmosis reduction and fixation: 'have we reached consensus?'

"My novel solution to a difficult problem / unusual new techniques or implants I am trying / implants that need improvement"

The session “My novel solution to a difficult problem / unusual new technique or implants I am trying / implants that need improvement” was an excellent opportunity for participants to present their innovative solutions for difficult clinical problems. Such an open forum fosters out-of-the box thinking across anatomical regions that could trigger new implant and instrument developments. The session on femoral neck fractures was an opportunity to analyze in clinical case discussions the performance of the Femoral Neck System from DePuy Synthes that was launched in 2017.

The case winner was Brett Crist (University of Missouri, Columbia, US) with his case about young femoral neck fractures.

The 7th AO TC Trauma Experts Symposium (North America) will be held in Bozeman, USA on September 1-2, 2023 and will be chaired by C Finkemeier.

13th Asia Pacific AOTK Experts Symposium, Malaysia

Chaired by MK Wong in Kuala Lumpur, Malaysia, on 28 March 2019, nine faculty from six countries in the Asia Pacific region and one from Switzerland led 34 participants from ten countries through the event.

During four lively sessions, 17 cases were discussed, and the

winning case presentation was given by Chen Xiadong, from Shanghai, China, in Session 3 – Treatment of Osteonecrosis of the Femoral Head in Young Adults.

The AO Technical Commission invites the winner to take part in the next Lower Extremity Expert Group Meeting.

One participant, Toni San Juan from the Philippines, said "it was a great learning opportunity and a chance to catch up with old friends, and make new ones as well."

The one-day event featured a special session led by Theddy Slongo, who gave a presentation on MAXFRAME System Software. This session was warmly received, and drew more attendees than had originally signed up for the session.

“Surgery is not just about inserting implants, it's also about surgical techniques and finesse in fracture reduction, temporary fixation, and final fixation. This is where new and cutting-edge techniques are showcased, subjected to group discussion, and then adopted across continents" said Chair MK Wong.

The 14th AO TC Trauma Experts Symposium (Asia Pacific) will take place on April 5-6, 2024 in Seoul, South Korea and will be chaired by JK Oh.

3rd Latin America AOTK Experts Symposium, Panama

R Pesantez successfully chaired the 3rd AOTK Latin America Experts Symposium in Panama City, which attracted 25 participants.

The program was varied and divided into five sessions. Each session was presented by a different member of the carefully selected regional faculty and included discussions on:

External Fixation
Geriatric Pelvis and Acetabulum fractures
Tibial Platea Fractures
Periprosthetic fractures of the femur
and challenges in proximal femoral nailing/role of augmentation

Faculty encouraged interaction amongst the participants and involved several case discussions. Many interesting conclusions were reached at the end of each session regarding the remaining clinical need in specific areas of fracture fixation.  Participants completed the two-day event with important learnings; including the following highlights:

A combination of locking plate and intramedullary device when fixing periprosthetic fractures seems to be a favorable option amongst many surgeons.

Fibular osteotomies in combination with the use of flexible plates is a common approach in Latin America when fixing posterolateral tibial plateau fractures.

The approach to fixing pelvic fractures could differ according to the mechanism of injury.

Every external fixator system has its own application.

The AOTK would like to thank all faculty and participants who attended at this event and would like to congratulate Fabio A  Suarez Romero and Renny A Cardenas Quintero for winning their case presentations in External Fixation and Challenges in Proximal Femoral Nailing/Role Augmentation.

1st CMF AOTK Experts Symposium, USA

The first AOTK CMF Experts Symposium was held on November 13–14, 2019, in Tampa, Florida, US. D Buchbinder chaired the symposium which was attended by 14 surgeons and 9 representatives from the industry.

The three symposium sessions focused on:

Patient specific orthognathic solutions
Patient specific solutions for orbit and midface reconstruction
Patient specific solutions for CMF reconstruction following ablative surgery

The participants exchanged their case experiences to discuss and to identify opportunities for improvement. Recent advances in digital planning and innovative approaches to design and to manufacture patient-specific surgical guides and implants allow that complex surgical procedures can be performed in a highly reproducible manner independent of the surgical experience. Although the costs that are currently associated with the use of patient-specific implants and cutting guides are high, there is a clear trend toward their increased use because of the high predictability and accuracy that can be achieved and the potential to reduce operating room time.

The case winner was Ruediger Zimmerer, with his case about bilateral TJR with counter-clockwise rotation in mandibular hypoplasia.

The 2nd AO TC CMF Experts Symposium will take place on October 12-13 in Copenhagen, Denmark and will be chaired by D Buchbinder.
