The level of fracture line as described by the Anderson and D’Alonzo classification is not predictive of the degree of instability or the risk of non-union. This classification scheme aids the management of odontoid fractures. In general, anterior oblique fractures are more stable than the posterior oblique fractures.
- type I: oblique linear fracture in which its line slopes forward, with dens displacement in an anterior direction
- type II: oblique linear fracture in which its line slopes backward, with dens displacement in a posterior direction
- type III: horizontal fracture line and the dens displacement can be either anterior or posterior
