SCIENTIFIC PROGRAM
8:00 a.m. - 11:00 a.m. - Pre-Course Program:
“Around the World Experience with Cervical and Lumbar Total Disc Replacement” Moderator: Scott L. Blumenthal, MD, PhD Total disc replacement has been in use for more than 20 years. On the continents of Europe, North America, South America, Asia, Africa, and Australia there are surgeons with high levels of experience with these devices and literature reporting good results, yet disc replacement has not gained universal acceptance as a treatment for painful disc degeneration. There are also reports expressing concern about wear debris and other complications. After the presentations, there will be a question and answer session during which the audience will be encouraged to ask questions to the speakers. Panel: 8:00 a.m. - 10:00 a.m. | Introduction: | Scott Blumenthal, MD | | Europe: (Where It All Began) | Michael Mayer, MD | | North America: | Scott Blumenthal, MD | | South America: | Luiz Pimenta, MD, PhD | | Asia: | C.K.

The need for collaboration, insight and coordinated action has never been greater. At this year’s meeting, SAS is offering a new, innovative program that will be based around Cervical, Lumbar and MIS case studies developed by leaders in the spine industry, called a World Cafe. The world café is an intensive round table discussion program that discusses a series of challenging case studies that will allow participants to confer on treatment options and protocols. Participants must select either CERVICAL, LUMBAR or MIS cases to review, then after rounds of discussion, the group will gather to share and explore emerging outcomes, insights and learnings. Learning Objectives: •.Participants will be able to learn from each other by listening together for patterns, insights, and deeper questions relating to their case study. •.By cross-pollinating ideas and sharing thoughts, collective discoveries and outcomes will be developed and that are meaningful to studies outcome.
