Abstract
Image-based navigation is recently accepted as one of the most profitable devices utilized to improve the accuracy of many procedures in orthopaedic surgery. Actually, navigation-assisted surgery systems were initially used in neurosurgery in the late 1980s. The interactive computer system is able to match the co-ordinate pre-or intraoperative images, patient’s anatomy and the surgical instruments by using tracking and registration process. The initial image-based navigation system has based upon preoperative computer tomography (CT) images and clinical application has been successfully introduced in spinal instrumentation since 1994.1-2 However, time consuming, comsplicated techniques and error in the registration process known as a pair-point matching remain the major concern and may cause CT-based navigation less popularity with time.
