Background: Ankylosing spinal disorder (ASD) patients are at a greater risk for spinal fractures due to osteoporosis and rigidity of the spinal column. These fractures are associated with a high risk of neurologic compromise resulting from delayed or missed diagnoses. Although computed tomography (CT) is usually the initial imaging modality, magnetic resonance imaging (MRI) has been proposed as mandatory to help identify spinal injuries in ASD patients with unexplained neck or back pain or known injuries to help identify noncontiguous fractures.

World Neurosurg 2017 Nov 4;107:194-201. Epub 2017 Aug 4.

Department of Neurosurgery, Heidelberg University Hospital, Heidelberg, Germany.

Background: Various surgical techniques have been described for treating odontoid instability and achieving effective stabilization. The earliest technique to be described proposed a C1 lateral mass entry point including neurectomy of the C2 nerve roots to ensure hemostasis. Because C2 neurectomy remains controversial, preservation of the C2 nerve root as described in Goel-Harms technique can lead to intractable occipital neuralgia and significant blood loss. Read More
