Vertebral Body Tethering (VBT) for Pediatric Scoliosis: A Comprehensive Guide
<p>This video, featuring experts from Cincinnati Children's and Akron Children's, provides an in-depth look at Vertebral Body Tethering (VBT) for pediatric scoliosis. It covers clinical scenarios, highlighting VBT's advantages as a minimally invasive, non-fusion alternative to standard spinal fusion. The discussion includes precise timing for the procedure, current indications for patient selection, detailed surgical techniques for thoracic and lumbar approaches, and post-operative outcomes, emphasizing improved recovery times for young athletes.</p><p></p><p>Vertebral Body Tethering (VBT) is an FDA-approved, minimally invasive, non-fusion surgical treatment for growing patients with idiopathic scoliosis. It aims to correct spinal curvature and modulate growth while preserving disc motion, offering benefits like earlier return to sports compared to spinal fusion. Optimal timing for VBT is critical, performed on skeletally immature patients near their peak growth velocity (typically ages 8-15) to avoid overcorrection or tether failure. Indications include moderately severe (40-60 degree) and flexible curves. The surgical approach varies by spinal segment, utilizing thoracoscopic techniques for upper vertebrae and open approaches for lumbar segments, with careful neuro-monitoring. While early outcomes data showed a learning curve with some revision rates, improved patient selection and increased experience are now yielding more successful results. VBT represents a significant shift towards guided growth modulation in pediatric scoliosis.</p>
