This new distraction technique uses a new surgical instrument designed to distribute distraction or compression forces across multiple pedicle screw anchors during spinal deformity correction, especially useful in posterior spinal growing rod surgery in the pediatric population. Previous techniques apply force through a single anchor, leading to potentially compromising fixation and implant failure. This new technique provides deformity correction and distraction via appropriately sized spacers that will sit on the rod and fit in between tulip heads. This technique will be most useful in deformity correction via concave distraction, particularly in growing rod insertion.
