The craniovertebral junction is the greatest mobile region in the whole spinal column and often associated with instability. Therefore, one must consider stability of this region in addition to decompression of the nervous system in the pathology of the craniovertebral junction. Two representative cases were shown here, one with Chiari I malformation associated with atlanto-axial dislocation and basilar invagination, and the other with atlantoaxial dislocation and periodontoid pannus associated with rheumatoid arthritis. The selection of surgical approaches and operative results in these patients were demonstrated to facilitate understanding of the current standards of spinal surgery in the craniovertebral junction.
