Degenerative spine disorders are very common, especially in the progressively older population. Although they are an integral part of any spine surgeon's daily practice, many questions remain unanswered, and continuing medical innovation introduces even more uncertainty. The course will take the form of didactic lectures and debates by the expert faculty, focusing on providing the best available evidence for each controversial question. Illustrative cases will also be presented, followed by open and interactive discussion amongst the faculty members and participants.
