• To highlight the advantages of using intraoperative navigation.
• To minimize radiation exposure during surgical procedures.

Methods Used

• Patient positioning in the prone position on a Jackson table.
• Harvesting bone marrow aspirate using a Jamshidi needle.
• Placement of a navigation reference frame into the posterior superior iliac spine.
• Intraoperative computed tomography scan for planning pedicle screw trajectories.

Main Results

• Successful navigation and placement of pedicle screws.
• Reduction in fluoroscopy time during the procedure.
• Enhanced surgical precision through intraoperative imaging.

Conclusions

• The method improves the safety and efficacy of transforaminal lumbar interbody fusion.
• Intraoperative navigation is a valuable tool in neurosurgery.
