Navigation of the Cervical, Thoracic and Lumbar Spine
Computer-assisted navigation (CAN) is a widely employed tool in spinal instrumentation surgery. It permits high-quality image guided placement of pedicle screws based on registration of preoperative or intraoperative spinal imaging data (e.g., preoperative or intraoperative CT images, intraoperative 3D fluoroscopy). The surgeon is thus provided with visual feedback showing the current planned screw placement trajectory superimposed on the imaging data of the patient. This is supposed to improve the safety and accuracy of pedicle screw placement and thus reduce complications potentially associated with screw misplacement, such as instability, neurological injury or revision surgery.
