Atlantoaxial dislocation(AAD)is a clinically challenging spinal surgery disease that can cause numbness and weakness of limbs,dysfunction of urination and defecation,even circulatory disorder and respiratory dysfunction in severe cases.The traditional treatment mainly involves loosening and reduction,relieving compression,local rigid fixation,and fusion,and is often accompanied by limited cervical activity after surgery.The bionic treatment concept of orthopaedic surgery differs from the traditional treatment concept.It advocates retaining the spinal movement function as much as possible,following the bionic treatment concept of stable structure and optimal function,and maximizing the upper cervical movement function while achieving AAD anatomical reduction.From the perspective of bionic orthopaedic surgery(BOS),this article aims to briefly describe the clinical classification of AAD,the choice of treatment and the evolution of internal fixation technology to provide a new idea and insight for the choice of treatment strategies for AAD.
