Atlantoaxial Dislocation
Conditions
Brief summary
The management of reducible atlantoaxial dislocation associated is challenging. Direct posterior distraction technique we proposed in 2010 could achieve satisfactory reduction. In 2020, we modified this technique and proposed a posterior intra-articular distraction technique. The intra-articular distraction technique could theoretically achieve satisfactory reduction and fusion. However, its superiority has not been proven. Therefore, we design a RCT study to compare the reduction rate and fusion rate of different strategies.
