C1–C2 pedicle screw fixation for adolescent with os odontoideum associated atlantoaxial dislocation and a compound reduction technique for irreducible atlantoaxial dislocation

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...

Surgical Management of Irreducible Atlantoaxial Dislocation

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, w...

Atlantoaxial dislocation

Atlantoaxial dislocation is the loss of normal alignment and stability of the first (atlas) and second (axis) cervical vertebrae with respect to each other. Etiologies are various, including trauma, congenital factors, infection, and connective tissue and autoimmune disorders. The condition must be appropriately diagnosed and managed to prevent deformity, spinal instability, and potential neuro...

Hangman’s Fracture with Concomitant Atlantoaxial Dislocation: a ‎Case Report

Background: Concomitant Hangman’s fracture and atlantoaxial subluxation is a rare phenomenon. Herein, we reported a victim of motor vehicle crash with traumatic spondylolisthesis of the axis and atlantoaxial rotatory dislocation. Case presentation: the patient was a 32 years old female with a chief complaint of severe neck pain and normal neurologic examination except for mild torticollis. Ima...
