5 Goal of the course The AO Trauma Masters Course Foot and Ankle covers the current concepts and techniques on how to recognize, characterize and treat complex injuries and deformities of the foot and ankle. Target participants Specialized orthopedic surgeons interested in advancing their expertise in the management of foot and ankle injuries and pathological conditions. Participants must have completed the AOTrauma Basic Principles of Fracture Management Course and preferably a regional subspecialty foot and ankle course. Participants must be willing to share their ideas and be able to communicate well in English. Learning objectives Upon completion of this course, participants will be able to: Identify the characteristics of complex foot and ankle fractures, dislocations, deformities and disorders Apply appropriate diagnostic tools to adequately assess foot and ankle injuries and deformities Formulate the principles for surgical techniques to treat traumatic injuries, deformities and disorders of the ankle, hindfoot, midfoot, and forefoot Use clinical and radiographic data to formulate an individual treatment plan Integrate the management of soft-tissue, tendon and cartilage pathologies Perform critical surgical approaches, osteotomies and fixation techniques on anatomical specimens Prevent, identify, and treat complications and recognize long-term outcomes Define appropriate treatment options for salvage of failed previous treatment procedures Course description Surgeons participating in this course will concentrate on the application of surgical planning and advanced techniques in the management of complex foot and ankle injuries and deformities. The course is taught in a modular format. Each module starts with a concise, case-based instructional lecture from one of the world's leading experts. Case-based interactive plenary sessions promote exchange between course participants and faculty members. Discussing cases in small groups deepen participants' understanding and application of decision-making and surgical management skills. At the anatomical specimen laboratories participants are trained in the application of different techniques and approaches. Ample opportunities are provided to share experiences and cases with peers and the expert international faculty. It is our intention to respond to the needs of participants by accommodating their topics of interest and facilitating discussions at an expert level. The course focuses on applying biomechanical and biological principles in fracture management in rare and common conditions, as well as on pitfalls, clinical tricks, and means to avoid complications. For reconstruction, the course focuses on surgical techniques for managing possible pathologies posttraumatic, systemic, and neurological.
