Neurosurgery - Cranio-Vertebral Junction

The craniovertebral junction (CVJ) is the region extending from the outlet ring of the skull- the foramen magnum- to C1 and C2 of the cervical spine- the atlas and axis, respectively. This is an uncommon site for tumors, including rare tumors of the lower cranial nerves or upper cervical nerve roots. Pathology of the craniovertebral junction includes stenosis of the foramen magnum from downward discplacement of the cerebellar tonsils, so called Arnold-Chiari malformation, treated with decompression of the foramen magnum and C1 laminectomy. The craniovertebral junction is also an important region for anatomic stability of the articulation of the head and spine; instability of the craniovertebral junction usually requires stabilization (fusion) of the atlas, axis, and/ or the occiput, for conditions as varied as tumor, infection, rheumatic instability, iatrogenic, and congenital instability.
