Treatment of irreducible atlantoaxial dislocation using one-stage retropharyngeal release and posterior reduction

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...

MR imaging of fatal atlantoaxial dislocation caused by retropharyngeal abscess.

A 9-month-old girl was evaluated in our emergency room for 1 03°F fever and decreased activity. Three weeks earlier, at another hospital , the patient had been treated with antibiotics and skin grafting for secondand third-degree scald burns. On the current admission, a nonfluctuant neck swelling was noted, but otherwise the results of the physical and neurologic examinations were normal. WBC w...

Irreducible 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...

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...
