A simple technique for easier anterior odontoid screw fixation

AbstractBackground: Anterior odontoid screw fixation (AOSF) is an osteosynthetic technique used for fixation of type 2 and rostral type 3 odontoid fractures. Compared to other treatment modalities, it provides immediate stability, preservation of the majority of the remaining C1–2 motion and an achieved union rate of 80–100%. AOSF requires a stable and reduced odontoid to allow for placement of guide wire and cannulated screw. Image guidance with neuro-navigation or intraoperative fluoroscopy are used for accurate placement of instrumentation. Minimally invasive techniques have been described, such as endoscopic or percutaneous placement of odontoid screws and the use of tubular retractor system. Major site-specific complications include neural injury, esophageal or pharyngeal perforation, hemorrhage, and airway obstruction.Purpose: To assess safety and efficacy of a new simple technique developed by the Authors for insertion of the odontoid screw through a less invasive anterior approach.Study design: Pr...
