Atlanto-occipital dislocation

In cases of atlanto-axial dislocation operated by the transoral route stabilisation of the spine is a crucial point. There are methods to achieve this fixation anteriorly. De Rougemount et al. (1966) placed a bone graft anteriorly from the ventral rim of the occipital bone to the level of the body of the axis.
