Computer-assisted navigation of anterior odontoid screw fixation for type II odontoid fracture: case report and practical positioning technique

Odontoid process fractures, particularly type 2 fractures, pose significant treatment challenges due to their high rates of nonunion. Anterior odontoid screw fixation (AOSF) is traditionally performed using percutaneous methods with biplanar fluoroscopy. Computer-assisted navigation has emerged as a promising tool to enhance surgical precision, but its application in AOSF is rarely utilized. Cervical spine stability during AOSF is crucial for optimal outcomes and navigational accuracy.
