[Surgical stabilization of C1 and C2 fractures]

We present operative procedures for the stabilization of fractures of C1 and C2. As is the case for fractures of the extremities, a direct approach to the injury should be attempted in order to avoid the inclusion of intact segments in the spondylodesis. The aim of the three presented techniques - direct screw fixation of fracture of the dens axis and traumatic lysis of C2 - is to active anatomical reconstruction by optimal stabilization. The new technique of transarticular screw fixation of C1-2 developed by Magerl allows unisegmental three-dimensional stabilization in cases in which at least a three-level fusion would have previously been considered necessary.
