====== Roy-Camille classification ====== The Roy-Camille [[classification]] of [[fracture]]s of the [[odontoid process]] of [[C2]] depends on the direction of the fracture line ((Roy-Camille R, Saillant G, Judet T et-al. Factors of severity in the fractures of the odontoid process (author's transl). Rev Chir Orthop Reparatrice Appar Mot. 1981;66 (3): 183-6.)) The level of fracture line as described by the [[Anderson 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. ===== Classification ===== 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 ===== References =====
