Navigation in minimally invasive spine surgery.

Overview

Minimally invasive spine (MIS) surgery is associated with limited dissection as compared to open surgical procedures and this can result in decreased visualization. The use of computer-assisted navigation technology, however, allows surgeons greater visualization of bony and soft tissue anatomy through limited MIS incisions. This article outlines the potential benefits of intraoperative navigation during minimally invasive spinal surgery procedures to reduce intra-operative radiation exposure and enhance surgical accuracy. We also offer the senior author's surgical setup and technique related to a skin-based navigation system. Future research is required into the use of augmented reality for surgeons during a navigated MIS surgery.
