Over 2 years, 16 patients with a total of 23 lesions of the craniovert
ebral junction and the upper cervical spine were treated. Clinically i
mportant aspects of diagnosis and classification are outlined. The con
ditions treated included fractures of the occipital condyle and atlas,
dens-axis, and hanged-man fractures. Standard operative treatment, wh
ich has to be modified in cases of combined injuries, is presented. Su
rgery is frequently indicated, especially in elderly and polytraumatiz
ed patients. In addition, 2 cases of atlanto-occipital dislocation are
described: 1 of these patients survived for 5 days after early atlant
o-occipital fusion.
