Techniques in the treatment of craniovertebral instability Goel Atul, Sharma Praveen, Dange Nitin, Kulkarni ArvindG Abstract The techniques of craniovertebral region stabilization introduced and used by the senior author over the last 20 years are summarized. The lateral masses of atlas and axis are strong and largely cancellous in nature and can be used for direct implantation of screws. Opening up of the joint and placement of bone graft within the joint stabilizes the region and provides a large area for bone fusion. Distraction of the facets provides an opportunity to treat a range of congenital craniovertebral anomalies. The technique of exposure of the lateral mass of the atlas and axis and the atlantoaxial joint is technically relatively complex and needs precise understanding of anatomy of the vertebral artery and training with cadavers. Keywords Atlantoaxial dislocation, basilar invagination, vertebral artery, syringomyelia
