Abstract:
There are some debates on the best method of treatment of C-2 fractures. Clinical findings and results of treatment were evaluated in forty-three patients with C-2 fractures. These fractures were classified into five types according to the classification by Benzel4);1) odontoid fractures(14), 2) horizontal C-2 body fractures(13), 3) sagittally oriented vertical C-2 body fractures (2), 4) coronally oriented vertical C-2 body fractures(8), 5) traumatic spondylolisthesis of the axis(6). Primary fusion appears to be justified in odontoid process fractures due to a high rate of non-union. In horizontal C-2 body fractures, unilateral facet dislocation was visible in six patients which was the cause of malalignment in closed reduction. In sagittally oriented vertical C-2 body fractures, combined facet fractures were always visible because the mechanism of injury was axial compression. The choice of management schemes may depend on the mechanism of injury and fracture type defined by Benzel.
