A Case of Atlantoaxial Dislocation associated with Dens Fracture treated with Anterior Screw Fixation

Abstract

The management of odontoid fractures varies widely among different surgeons and has long been a subject of controversy. Particularly, type 2, unstable type 3 and "shallow type" type 3 fractures have a high rate of non-union when treated with external bracing. Anterior screw fixation, originally described Nakanishi and Bohler, has been the best teratment method for these fractures and many surgeons prefer this technique. We here describe a case of atlantoaxial dislocation associated with dens fracture treated with anterior screw fixation and discuss operative indication, technique, and postoperative management.
