Background: Image-guided technology has greatly broadened the scope of modern surgery. Objective: Evaluation of the accuracy of pedicle screw placement using navigation and the safety offered to the surrounding structure during screw placement and affection of the workflow. Methods: eight patients with dorsal and dorso-lumber instability were operated upon by pedicle screw fixation using 3D image guidance. BrainLAB Vector Vision (BrainLAB, Inc.). all patients had preoperative, intra-operative and postoperative imaging. Results: no vascular or neural complications were encountered, accuracy in choosing the entry point was high (100%) and accepted in medio-lateral inclination (62.5% perfect match and the rest showed minimal deviation less than five degrees). Conclusion: The use of spine navigation in the placement of pedicular screws provides higher accuracy, and is safer to the patient with less percentage of misplacement.

Key Words: instrumentation, spine navigation, spine instability.
