New dye helps surgeons see inside the spine during surgery

This study tested a new technique using a special contrast dye to help surgeons see how well they were removing disc material during a common spinal fusion surgery called TLIF. Researchers compared outcomes between patients where surgeons used this visual feedback and those who used the standard technique. The goal was to see if this real-time visual aid could improve the quality of the disc space preparation and potentially lead to better patient outcomes.
