P174 - Optical Topographic Imaging for Spinal Intraoperative Three-Dimensional Navigation in Minimally Invasive Approaches: Initial Preclinical Experience

Abstract

BACKGROUND CONTEXT: Computer-assisted three-dimensional navigation may guide spinal instrumentation. The utility of intraoperative navigation is most evident in minimally-invasive (MIS) and deformity-correcting procedures, where anatomic landmarks are less readily identifiable. A novel optical topographic imaging (OTI) system for spinal navigation has been developed and described separately. While it offers comparable accuracy and significantly faster registration relative to current navigation systems, OTI to date has been applied only to open posterior exposures.
