Summary

This study tested a device called NeuroVision that monitors nerve activity during spine surgery. It has a new feature that checks if screws are placed correctly as they go in, rather than after. The goal was to see if this real-time check helps surgeons avoid nerve problems. The study involved 60 adults having lumbar fusion surgery.
