Spine surgery showdown: which fix keeps teens moving best?

This study looked at two types of surgery for teens with scoliosis (a curved spine). One method, called vertebral body tethering (VBT), uses a flexible cord to straighten the spine while allowing more natural movement. The other, posterior spinal fusion (PSF), permanently fuses the bones together. Researchers compared how well each corrected the curve and how much spine flexibility was preserved over time. The goal was to see which approach offers better long-term function and safety.
