MILNE LECTURE Part I: Operative Orthopedics of the Fetlock Joint of the Horse: Traumatic and Developmental Diseases of the Equine Fetlock Joint Larry R. Bramlage, DVM, MS The invitation to present the Frank J. Milne State-of-the-Art Lecture is a special degree of flattery for one’s career. The flattery comes with a degree of responsibility to present the current state of practice and, to a certain extent, challenge doctrine and lay out theories of practice that result from one’s years of practice in a specialty area. The lecture should, therefore, enjoy the possibility of moving the “state of the art” forward. In areas where the author of this manuscript has a view of pathology that varies from the current concepts, the views will be presented as theories based on years of observation and, where possible, controlled studies. The object is to lay them out for examination and challenge or refutation by future practitioners of this specialty. I want to thank the members of the American Association of Equine Practitioners for this opportunity.
