[Morphologic changes in the cervical division of the spinal column in the Klippel-Feil syndrome].

The authors describe a patient with abnormal development of the cervical vertebrae and the formation of a block typical of the Klippel-Weil syndrome, as well as craniovertebral synostosis with the complete absence of the atlantooccipital joint, a bizarre and complicated course of the canals of vertebral arteries and sublingual nerves. They also outline the mechanisms of the possible development in such conditions of neurological symptomatology and disorders of cerebral, spinal and radiculo-neural blood circulation.
