We present two patients with a cerebral palsy who developed cervical myelopathy long from term involuntary movements. Frequently instability with a premature onset of spondylosis of the cervical spine is found in an athetoid cerebral palsy patient. These structural abnormalities appear to be related to the athetoid motion of neck in a cerebral palsy. The combination of a disk degeneration and listhetic instability with a narrow canal predisposes these patients for the relatively rapid progression to a devastating neurological defect. Early surgical management is a treatment of choice for the cervical myelopathy associated with an athetoid cerebral palsy.
