image-guided navigation

image-guided navigation

a stereotactic surgical technique that uses preoperative CT or MRI data that are matched to the corresponding surgical anatomy using three-dimensional coordinates. These coordinates may be surface markers attached to the skin overlying the imaged anatomy or, in the case of spinal navigation, may be discreet anatomic landmarks on the exposed surgical anatomy. The technique is used for sundry intracranial, spinal, ENT, and orthopedic procedures to enhance intraoperative accuracy and anatomic orientation.

Pelvic fixation 'opportunity tunnels' are narrow and multiplanar images are necessary to avoid damage to vulnerable nearby neurovascular structures, such as the L5 and S1 nerve roost, cauda equina at the level of the first sacral vertebra, and the crossing of the femoral vein and artery superior to the superior pubic bone.[17] Pelvic ring injuries that are treated with iliosacral screws, using image-guided navigation, show 96% of well-placed screws in postoperative radiographs and CT scans,[18],[19] but a medical robotic system has not yet been established for percutaneous iliosacral screw placement.
