Case Studies Spine Talks

The challenges of life in the 21st Century require us to find new ways to access the wisdom and intelligence inherent in groups both small and large. The need for collaboration, insight and coordinated action has never been greater. ISASS15 will continue and expand on past successes with featured events developed by leaders in the spine industry.

Room 1 - Deformity Correction with MIS Techniques
Moderator(s): Juan Uribe, MD

Room 2 - Treatment of L4-5 degenerative Spondylolisthessis
Moderators(s): Vikas Patel, MD

The Spine Talk is an intensive round table discussion program that presents a series of challenging case studies and allows participants to confer on treatment options and protocols.

Device demonstration tables will be added to expand the Spine Talks program content. A tabletop for each participating device company will be available for hands-on product display. Surgeons will visit each tabletop for a specific period of time and rotate to the following table. The devices will remain in the room for the Spine Talk session while related cases are discussed.

Participants must select either "Deformity Correction with MIS Techniques" or "Treatment of L4-5 degenerative Spondylolisthessis" cases to review.

After rounds of discussion, the groups will gather to share and explore emerging outcomes, insights and new knowledge. By cross-pollinating ideas and sharing thoughts, collective discoveries and outcomes will be developed that will be meaningful to case outcomes.
