This interview is for educational purposes and covers information provided by Dr. Per Trobisch regarding his opinions on Vertebral Body Tethering (VBT) Non-Fusion Scoliosis Surgery. This video is not an endorsement. Viewers should consult their physicians and treating team accordingly. See highlights via timestamps below. Chapters 00:00 Introduction 1:30 Surgical screening 5 scoliosis curve types. When to use VBT vs Fusion. 8:22 Perspective on VBT for sagittal alignment of the spine. 10:51 Ideal Candidates for VBT. 11:21 Case 1: Lumbar VBT, single tether (Sanders 5). 16:50 Are 2 tethers better than 1 tether? 19:16 Biomechanical testing of single & double tethers. 21:32 Case 2: Lumbar VBT, double tether (Sanders 7). 23:59 Perspective on triple and quad tethers. 25:38 New larger stronger tethers. 27:00 Tether breakage does not mean failure. 27:28 Case 3A: Lumbar VBT, double tether failure. 31:30 Finding tether breaks on x-ray. 32:51 Analysis of tether breakage post revision surgery. 33:30 Posterior tether breaks 1st followed by anterior tether. 34:17 Tether breakage occurs between screws at disc level. 35:29 Where do tethers break the most often? 36:03 Rotation at curve apex can place more tension on flexible ends of tether span. 37:24 Biomechanics of tether breaks are different in vivo vs in a lab. 38:29 Case 3B: Lumbar VBT, double tether failure with revision. 39:54 Case 3C: Lumbar revision hybrid VBT with 2 level apical fusion. 41:00 How to determine which levels to fuse with this hybrid VBT apical fusion technique? 42:33 Case 4: Double curve hybrid VBT with apical fusion (Sanders 3). 46:12 For hybrid VBT with apical fusion, will the fusion hold without rods and screws? 47:55 Is hybrid VBT with apical fusion an option for more mature scoliosis cases? 50:00 Is hybrid VBT with apical fusion an option for thoracic curves? 50:55 Dr. Trobisch's pediatric vs adult disc maturity hypothesis. 57:04 The future of Vertebral Body Tethering (VBT). facebook.com/groups/11982... drdereklee.com/
