The AO VET NA Blended Course - Principles of Small Animal Fracture Management is designed to provide participants with a basic, fundamental knowledge of bone healing and how it can be favorably influenced through internal fixation of fractures. The scientific principles of fracture repair and their practical application to the clinical situation are presented in lectures and hands-on laboratory sessions. Techniques which are critical to a successful surgical outcome, such as soft tissue handling and bone grafting, are discussed as well as the problems of non-unions, infections and technical errors. There will be breakout sessions (Small Group Discussions / Firesides) which supplement the lecture topics focusing on fracture cases and will further examine the importance of preoperative planning and other aspects of the clinical decision-making process in small animal surgery. The total patient is considered in terms of pre-and post-operative care and anesthetic management.
Participants should leave this course with the information and experience necessary to apply these principles and techniques to commonly encountered fractures in small animals.
This principles-level course will provide a platform for future study and career development in veterinary orthopedics.
The new 'blended' course format includes REQUIRED online coursework and learning materials provided prior to the face-to-face event which are MANDATORY for completion and attendance at the course.
NEW!!!! This course is a FULL 3-day course, rather than a 3 and 1/2-day course as previously offered
NOTE: In addition to the in-person course event, April 10-12, 2024, in Columbus, OH, there will be four (4) live ZOOM pre-course online sessions with additional lectures and clinical case presentations (information to be sent closer to the time of the sessions):
