What does the posterior spinal fusion procedure for scoliosis involve?
Posterior spinal fusion (PSF) corrects scoliosis by accessing the spine from the back. Surgeons place pedicle screws into the vertebrae and connect them with rods to straighten the curve. Bone graft is added to fuse the segments into a solid unit. This is performed under general anesthesia with intraoperative neuromonitoring to protect spinal nerves.
