Since 1975 eight patients with upper cervical spine injury (fracture of the posterior arch of the atlas in one, fracture of the dens in three, pure anterior atlant-axial dislocation in one, Os odontoideum in one, hangman's fracture in two) were treated.Two patients (fracture of the dens, pure anterior atlant-axial dislocation) were not definitely diagnosed during six months after injury. These two cases and one case of Os odontoideum were treated with posterior C. 1 to C. 2 fusion, others conservatively.The case of pure anterior atlant-axial dislocation was operated only two weeks before. A follow-up study for five months to 5.6 years revealed rather good results in the other seven cases.
