Neuro Navigation Versus Conventional Spinal Techniques in Analyzing Nerve Injury and Anatomical Accuracy: A Systematic Review.

Abstract

Neuronavigation, a computer-assisted surgical technique, enhances the accuracy of spinal surgery by using medical imaging to guide the surgeon's instruments. This method mitigates the serious complications of screw misplacement, such as dural tears, nerve damage, vascular injuries, and internal organ damage, by integrating pre-operative imaging data with real-time intraoperative sensor readings. Because of this integration, it is possible to visualize the spine in three dimensions, guaranteeing accurate instrument placement and greatly lowering the risk of complications. Despite its growing popularity, the benefits of neuronavigation in spinal instrumentation are debated. While some studies report improved accuracy in pedicle screw placement, others find no significant difference compared to conventional freehand techniques. Further research is required to determine the long-term benefits of neuronavigation, including its impact on patient outcomes, like reduced pain and improved function. This systematic review will evaluate the evidence on the risks and benefits of neuronavigation in spinal instrumentation surgery, compared to conventional techniques.
