Spinal instability may require the fusion of multiple levels of vertebrae by the placement of metal screws as anchors and metal rods as connectors. Of the approximately 500,000 spinal fusion surgeries performed annually in the United States, over 20% of screws are misplaced. This potentially leads to postoperative neurological or vascular complications, which necessitate reoperations in 1% to 5% of all patients.

White Light Medical had developed the AccuSpine pedicle probe, a device that will significantly reduce breaches by ensuring that the probe is always positioned within the lower-density bone. We have demonstrated proof of concept through ex vivo porcine spine testing and cadaver testing. White Light Medical is continuing to develop this technology and is seeking funding to commercialize the product.
