Performance Measurement and Safety Evaluation of the PYTHEAS® ODYSSEE Angular Assistance System for Intra-pedicular Screw Placement in Adult Spine Surgery

Pre-surgery, the surgeon generates a 3D model of the spine from a preoperative CT scan During the perforation and insertion of the implant, the system indicates the orientation of the pedicle path and the current orientation of the instruments (perforation tool) with the orientation sensor (inertial sensor). The system also displays the position of the entry point of the planned pedicle path on the views.
