Full-Endoscopic Anterior Odontoid Screw Fixation: A Novel Technique and Technical Report

Abstract Background: Odontoid fractures are common among cervical spine fractures and are categorized into three types. Unstable type II fractures are among the most challenging to treat, and the best treatment approach has been debated. Anterior odontoid screw fixation, a surgical treatment option, yields a high union rate and helps preserve cervical motion; however, there are risks for approach-related complications. Here, we report a novel minimally invasive technique of full-endoscopic anterior odontoid fixation (FEAOF).Methods: The authors introduce the technique and describe in detail the technical approach of FEAOF for the surgical treatment of type II odontoid fractures.Conclusions: FEAOF is a feasible and effective option for treating type II odontoid fractures. The procedure is less invasive than other techniques and provides clear direct visualization of the involved structures.Level of Evidence: Not applicable
