💡 AI Summary & Key Takeaways
– VBT is an innovative, non-fusion alternative that preserves natural spinal motion and flexibility.
– Utilizes a flexible biocompatible cord attached via thoracoscopic keyhole access to modulate growth.
– Ideal for growing adolescents with progressive idiopathic scoliosis.

The Mechanism of Dynamic Vertebral Body Tethering
Vertebral Body Tethering (VBT) is a motion-sparing, anterior scoliosis treatment. By placing biocompatible titanium screws linked with a tensioned flexible polymer cord along the convex side of the curve, it harnesses the patient’s remaining growth to naturally straighten the spine without rigid fusion.
Candidate Selection for VBT
- Skeletally immature adolescents (Sanders score 2–4 / Risser 0–2).
- Flexible idiopathic thoracic or lumbar curves ($40^circ – 65^circ$).
- Young athletes aiming to preserve full spinal mobility and athletic agility.
