[Late complications of the upper cervical vertebral column trauma].
Two different types of myelopathy course were discerned: myelopathy due to instability, occurring early after trauma, rapidly progressing and myelopathy due to the long lasting ventral compression of spinal cord at the craniocervical level, occurring in several years after trauma, slowly progressing. The conduction of occipitocervical spondilodesis using metal loop with the vertebral arches fixation in myelopathy due to instability and odontoidectomy in the spinal cord ventral compression on craniocervical level constitutes the method of choice for the late complications in craniocervical junction trauma.
