Objective Through comparing different methods of posterior approach fixation, to find out an ideal way for treating atlanto-axial instability.Methods Thirty-four cases of atlantoaxial instability treated surgically in the last 5 years were reviewed. The indication, stability and curative effect of different surgical treatment methods were studied comparatively and the results were analysed. Results Different methods of fixation resulted in different outcomes according to different causes of atlanto-axial instability. Posterior cable fixation was the suitable method of fixation for atlanto-axial instability caused by odontoid fractures, which was also suitable for atlano-axial instability caused by rheumatoid arthritis but needing rigid head-neck-chest combined plaster fixation after operation. There was no significant difference between Apofix and Brooks fixation. The most reliable method of fixation was with Magerl screw system.Conclusion According to the different causes of atlanto-axial instability, posterior approach fixation should choose different methods of fusion and assisted external fixation.
