The fractures of Odontoid type II according to the classification of Anderson and D'Alonzo are considered the most unstable and were always difficult to handle. External immobilization is used as a frequent method by some authors, however surgery provides better fixation. Back surgery such as inter laminar and Magerl interfacetaria are used but they block the rotational mobility of the atlas axis segment. Bohler describes the first surgeries previously, this technique was modified in recent years and is currently being performed with minimally invasive approach techniques.
In the present work we present the experience of the technique used in our series and a review of the literature with respect to this pathology and the techniques of management of such lesions.
