[Management and outcome of type II fractures of the odontoid process].

Background: The most effective treatment of type II dens fractures according to Anderson and D'Alonzo remains controversial as there is no guidance on the choice of conservative or surgical therapy and if the anterior or the posterior approach is more advantageous. In 1993 Eysel and Roosen showed that the consolidation rate of type II odontoid fractures mostly depends on the morphology of the fracture and established a classification with corresponding treatment recommendations.

Objective: The investigation aimed at clarifying the outcome of type II dens fractures treated according to the recommendations of Eysel and Roosen.
