Surgical Management of Irreducible Atlantoaxial Dislocation
نویسندگان
چکیده
The classification and treatment of atlantoaxial dislocations (AAD) remains controversial. Despite existing debate among the literature, it is generally accepted that the treatment of symptomatic AAD should be surgical reduction and fixation. More recently, there has also been acknowledgement among treating surgeons that there are substantial differences between irreducible and reducible AAD, with significant differences between the two groups in terms of the severity of clinical presentation and ideal management [1]. Presently, however, there is little agreement on how best to manage IAAD. Specifically, the importance of anatomical reduction and the method of obtaining proper alignment surgically varies based on the treating surgeon and institution. The purpose of this commentary is to briefly discuss current options for the surgical management of IAAD.

Transoral approach for revision surgery of os odontoideum with atlantoaxial dislocation.
Revision surgery for os odontoideum with irreducible atlantoaxial dislocation with a transoral approach is not commonly seen. Typically, management of this type of atlantoaxial dislocation is through posterior fixation and fusion or transoral decompression and posterior fusion. This report describes revision surgery in a patient with os odontoideum who was treated with a transoral approach. A 5...
متن کاملIrreducible Atlanto-Axial Dislocation in Neglected Odontoid Fracture Treated with Single Stage Anterior Release and Posterior Instrumented Fusion.
It is a well-know fact that type 2 odontoid fractures frequently go into nonunion. If left untreated, patients may develop irreducible atlantoaxial dislocation (AAD). We describe the surgical management of two patients with neglected odontoid fractures and irreducible AAD treated with single stage anterior release followed by posterior instrumented fusion. Both patients presented with history o...
متن کاملNew clinical classification system for atlantoaxial dislocation.
The purpose of this study was to define a new clinical classification of atlantoaxial dislocation based on its clinical manifestations, namely reducible atlantoaxial dislocation (RAAD), irreducible atlantoaxial dislocation (IAAD), and fixed atlantoaxial dislocation (FAAD). A total of 107 patients with atlantoaxial dislocation were respectively treated based on this clinical classification, incl...
