AO Technical Commission Meet the Experts

Excellence in innovation on display.

This popular format offers the opportunity to learn about the AO Technical Commission's most recently approved medical devices and to explore hot topics in trauma and orthopedic surgery. The sessions showcase clinical benefits of innovative devices and surgical techniques which are so new that they have not yet been included in AO course programs.

In an engaging series of stage shows featuring practical demonstrations, expert surgeons who are directly involved in the development of new implants and instruments present clinical cases and explain the benefits of new solutions for patient care. The sessions are streamed live and available thereafter on our website.

Meet the Experts 2019

 Wherever you are in the world, whatever your field of interest, Meet the Experts has something for you.

RIA 2 System: Next Generation Reamer-Irrigator-Aspirator

RIA 2 is the next generation Reamer Irrigator Aspirator system which allows efficient clearing of the intramedullary cavity of debris and harvesting of autograft. Furthermore, it offers fewer complications during reaming compared with iliac crest bone graft harvesting, efficient management of infection, reduced procedure time, and improved patient outcomes. Two trauma surgeons, Brent Norris and Martijn Poeze, introduced the new and improved features of RIA 2 including an overview of the device technology, indications for use and case examples. The lively and interactive session included a hands-on demonstration of device assembly and femoral reaming. The surgeons shared their considerable expertise and experience with this technology to offer tips and tricks for effective use of the RIA 2 system. These tips encompassed reaming entry points, measurement of the intramedullary canal, optimal reaming technique for bone harvesting, and the avoidance of potential technical challenges.

Planning and Performing Maxillo-Mandibular Distraction Osteogenesis

Complex congenital and acquired deformities in the mandible, the midface, or cranium might require gradual correction with distraction osteogenesis. The CMF distractors are used for patients from birth to almost every age depending on the clinical situation. Callus distraction and final shaping along a guiding fixation allows the correction of complex deformities and filling of voluminous voids in bone structures. Virtual planning of the distraction vector for callus formation or bone transport as well as the fixation of the distractor and the final reconstruction are currently state of the art. Alberto Rocha Pereira presented exemplary cases and emphasized the wide variety of applications of CMF distraction in the mandible and midface area to solve different clinical problems to improve patients' outcomes.

Application of the LCP Distal Femur Plate in Comminuted Fractures of the Proximal Phalanx in Horses

Comminuted fractures of the proximal phalanx are common injuries in horses and even though the prognosis for survival is guarded and complications are common, the currently recommended treatment is to immobilize the distal limb in a transfixation cast. Christoph Lischer, Fabrice Rossignol, and Jeffrey Watkins from the AO TC Large Animal Expert Group presented the biological bridge plating using the human LCP Distal Femur Plate that can provide a better alternative with fewer complications and better long-term outcomes. During the highly informative session, the three experts outlined the underlying principle, provided detailed information about surgical steps, and exemplified those in a practical demonstration on a bone model. Rossignol, the driving force behind this newly developed technique, underlined the necessary postoperative management including casting, adequate trimming, and shoeing to improve patients' outcomes.

Patient Specific Procedures in CMF - State of the Art

Patient specific implants (PSIs) and cutting guides are widely used in orthognathic procedures, in orbital and midface trauma, and post-ablative reconstruction of the craniomaxillofacial skeleton. They have revolutionized planning and execution of these procedures resulting in improved efficiency in the operating room and more predictable outcomes. PSIs are available as 3D printed Titanium, milled Titanium or reinforced PEEK devices depending on application and surgeon preference. Daniel Buchbinder and Damir Matic, key opinion leaders and members of the AO TC CMF, presented this innovative technique along with comprehensive workflows developed in the AO TC CMF.

Elastic Nailing for Children's Fractures: How to Avoid Complications

Elastic stable intramedullary nailing (ESIN) has become the method of choice for internal fixation of long bones in children and teenagers aged 4–14 years. However, ESIN treatment can also lead to complications like loss of reduction following push-out of the nails at the entry site, especially in unstable femoral shaft fractures. Nail migration with subsequent soft-tissue and skin irritation has been reported to be as high as 5–12%. In this Meet the Experts session, Unni Narayanan and Theddy Slongo, from the AO TC Pediatric Expert Group, presented in a hands-on session the best practices with ESIN to avoid complications in pediatric fracture treatment. Slongo explained the basic biomechanical principles of ESIN to provide stability: symmetrical bracing and 3-point contact. The two presenters shared femoral, tibial and forearm fracture cases with recommendations for preoperative planning as well as for correct insertion and positioning of ESIN.

Minimal Invasive Rib Stabilization

Chest wall trauma with multiple rib fractures and flail chest are injuries with mortality rates as high as 20% and major complication rates of up to 40%. The number of surgical procedures for rib fracture stabilization has increased as dedicated implants and instruments became available. The development of improved tools has led surgeons to perform rib fracture fixation through smaller incisions. Innovative surgical techniques make this type of surgery available to an increasing number of patients. Stefan Schulz-Drost and Mario Gasparri, two leading experts in thoracic surgery, provided an insight into minimally invasive rib stabilization using the MatrixRIB Fixation System (for rib and sternum fractures) and the recently developed self-drilling screws. Schulz-Drost provided a comprehensive overview about the different surgical procedures available for the median, lateral, and posterior chest wall regions. A hands-on demonstration led the audience through a minimal invasive procedure for sternal fracture fixation.

Fracture-related Infection: New Consensus on Diagnosis and Treatment

Fracture-related infection (FRI) remains a challenging complication and is a heavy burden for orthopedic trauma patients, their families and treating physicians, and for the healthcare systems. Standardization of the diagnosis and treatment of FRI has been lacking, which has made it difficult for researchers to perform and compare studies in this field. In this Meet the Experts session, key opinion leaders in FRI, Willem Metsemakers and Bill Obremskey, presented the recently published consensus recommendations for the diagnosis and treatment of FRI. Developed by an international group of recognized experts in FRI, the evidence-based recommendations encompass confirmatory and indicative features for the diagnosis of FRI; general treatment principles comprise risk stratification, patient optimization and a multidisciplinary team approach; surgical management and antimicrobial treatment.

AO Recon - Introduction to AO Recon Complex Exercises

This webcast offers an insight into the brand new AO Recon dry bone practical exercises developed in 2019 to enhance the AO Recon Complex course on Total Hip and Knee Arthroplasty. Our experts in the field discuss the development of the exercises and demonstrate some of the models at the AO Davos Courses 2019.
