The [[Roy-Camille classification]] scheme aids the management of [[odontoid fracture]]s. In general anterior oblique fractures are more stable than the posterior oblique fractures. In 2005, Grauer et al. proposed a modified, treatment-oriented classification of odontoid fractures. This classification divided odontoid fractures into 3 groups, especially type II fractures into three subgroups (subclass A, B, and C) ((Grauer JN, Shafi B, Hilibrand AS, Harrop JS, Kwon BK, Beiner JM, Albert TJ, Fehlings MG, Vaccaro AR.
