Abstract:
Traumatic spondylolisthesis of the axis is the fracture of both pedicles and is called commonly as hangman' s fracture. The fractures with the anterior displacement more than 3mm and the angulation, more than 11 degrees were classified as unstable and the surgical methods were recommended for the treatment of the fractures. As for the surgical methods, anterior C2-3 fusion with plate fixation or transpedicular screw fixation were used. However, the differences between the clinical results of both methods were not reported in the literatures. In order to clarisy the clinical results of both methods, the authors evaluated the clinical results of 11 patients treated by anterior plate fixation and 7 patients treated by transpedicular fixation who were operated on between Mar. 1987 and,Jan: 1992. Minimum follow-up period was 12 months. 1. As the surgical complications, two cases of transient dysphagia in anterior fixation group and three cases of malinserted screw in transpedicular fixation group were observed. 2. Limitation of rotatory neck motion, less than 20 degrees in one direction was observed in four cases of transpedicular fixation group. 3. Anterior angulation, more than 10 degrees was noted in three cases of transpedicular group. 4. Mild intermittent neck pain was observed in two cases of anterior fixation group and two cases of transpedicular fixation group. Constant neck pain was present in three cases of transpedicular fixation group. 5. Over-all clinical results were excellent or good in all of anterior fixation group, and in four of seven transpedicular group. Although the clinical materials were limited in number, method of anterior plate fixation was recommended by the authors in the management of traumatic spondylolisthesis of axis, because of the easier technique and the better clinical results than the transpedicular screw fixation.
