Scoliosis Tethering Surgery

Scoliosis Tethering Surgery (VBT) is a newer surgical procedure designed to correct spinal curves (scoliosis) in growing individuals while preserving spinal flexibility. Unlike traditional spinal fusion surgery, which involves fusing vertebrae together to stop curve progression, Scoliosis Tethering Surgery uses a strong, flexible cord (the “tether”) that is anchored to screws placed into the outer (convex) side of the curved vertebrae. The surgeon applies tension to this cord, immediately pulling the spine into a straighter position. The ingenious aspect of VBT lies in its reliance on continued growth: as the patient grows after surgery, the tether acts as a brace on the convex side, restricting growth, while the inner (concave) side is encouraged to lengthen and “catch up,” gradually correcting the curve over time. This motion-sparing technique makes it an attractive option for adolescents with moderate to severe idiopathic scoliosis who still have significant growth remaining, aiming to achieve correction without the rigidity associated with spinal fusion.
