Trolley Gliding Vehicle Device used in patients with Early Onset scoliosis A. Aoude, L. Simoes, S. Aldebeyan, J. Ouellet McGill University Division of Orthopedics- Spine Surgery McGill Scoliosis & Spine Group

Basic & Clinical Research Disclosure Dr. Jean Ouellet is a consultant for Depuy Synthes Growing Rod Technologies Commercial Interest What was Received For What Role Depuy Synthes AO Foundation Honorarium / Travel Research Funds Teaching / Consultant Basic & Clinical Research Teaching McGill Scoliosis & Spine Group

Objective To present TGV an innovative device and the new surgical technique along with early results of implantations of the device CE mark EU approved UhmwPE TAN PEEK TGV McGill Scoliosis & Spine Group

Indications Patient comorbid factors which increased surgical risk for repetitive surgery Growing patient: Older than 5 younger than 10 Flexible curves

Surgical Technique Low profile Solid proximal and distal Apical Control Trans-muscular dissection at APEX - insertion TGV implants Strategic placement of gliding anchors Two pairs of rod McGill Scoliosis & Spine Group

Case 2 Case 3 Case 1

Growth Guiding System Case Example

Day 7 PO 3mo PO 6mo PO

Results Six patients with Early Onset Scoliosis were treated with TGV by a single surgeon at three institutions Results Average Age 7.2 years (5-11 years old) Average Pre-Op Cobb 76.60 (50-1000) Average Post Op Cobb 30.20 (0-550) Average Correction 60% (50-73%) Average Follow Up 8 months McGill Scoliosis & Spine Group

Conclusion We present early results of a new spinal gliding implant in six patients Surgery technically feasible Trolley Gliding Vehicle showed good correction of spinal deformity Results can not provide any long term conclusion McGill Scoliosis & Spine Group
