研究目的：
At present, there is a lack of standardized, large-scale, and high-level evidence-based medicine research on the safety and effectiveness of treatment of irreducible atlantoaxial dislocation (IAAD).Based on this, the goal of this prospective randomized controlled study is to systematically investigate the optimal surgical approach (simple posterior approach and the combined anterior and posterior approach) for managing IAAD, providing insights into the most efficacious and safest course of action. And long-term follow-up will be conducted on patients to evaluate the safety and effectiveness of different surgical methods, and to develop diagnostic and treatment standards for irreducible atlantoaxial dislocation.
