[Expert consensus on posterior facet distraction and fusion technique for the treatment of atlantoaxial dislocation(2024)].

Atlantoaxial dislocation is a common bony structural deformity in the craniovertebral junction area. It can cause severe neurological defects, seriously affect the patient's life quality, and even threaten the patient's life. The most effective treatment for patients with apparent clinically symptoms is surgical treatment. In recent years, with the development of surgical techniques, posterior facet distraction and fusion (PFDF) technique has gradually become an important technique for the treatment of atlantoaxial dislocation. In order to better standardize the diagnosis and treatment of patients with atlantoaxial dislocation and the application of PFDF technique, based on the existing evidence, the Spine and Spinal Cord Group in Neurosurgical Society of Chinese Medical Association and the Chinese Craniovertebral Junction Malformation Research Alliance and Craniovertebral Junction Malformation Alliance of National Center for Neurological Disorders organized experts in relevant fields to fully discuss and formulated the "Expert consensus on posterior facet distraction and fusion technique for the treatment of atlantoaxial dislocation（2024）". This consensus elaborates and recommends the preoperative evaluation, surgical techniques, and management of complications using PFDF technique for the treatment of atlantoaxial dislocation. It is intended to provide guidance for surgeons who encounter problems in the treatment of atlantoaxial dislocation using PFDF technique.
