What is Craniocervical Instability?

The Pain Relief Foundation


Craniocervical Instability (CCI), also known as the Syndrome of Occipitoatlantialaxial Hypermobility, is a structural instability of the craniocervical junction which may lead to a pathological deformation of the brainstem, upper spinal cord, and cerebellum. It primarily occurs in patients with Ehlers-Danlos Syndrome and other hereditary disorders of connective tissue.

Some HDCT/CM1 patients have been found to additionally have tethered cord syndrome (TCS). The size and volume of the posterior cranial fossa were found to be normal in the above study, with a comparatively large foramen magnum, and elongated brainstem. The conus medullaris was in a normal position (except in very young patients), and the filum terminale was found to be fine and taut. A diagnosis of TCS was based on the following symptoms and signs: urinary dysfunction, bowel incontinence, low back or leg pain, lower extremity numbness or weakness, loss of deep tendon reflexes of the lower extremities, thoracolumbar scoliosis, equinovarus/ equinovalgus foot deformities, syringomyelia and spina bifida occulta. TCS was found to be more common in patients with only low-lying cerebellar tonsils.
