Objectives:
Discectomy and inter-vertebral body fusion combined with the anterior plate-screw fixa tion is the common procedure in cervical spine surgery. But the anterior plate-screw fixation of the C2 spine has been the uncommon surgical procedure. In this study, we analyze the anatomy of the C2 body relevant to C2 anterior plate-screw fixation.
Material And Methods:
Eighty-six dried C2 spines were evaluated directly for this study. Measurements were made on the C2 body width and midsagittal anteroposterior (AP) depth and the anteroposterior parasagittal depth 5 mm lateral to midline on the inferior endplates, in addition to on the middle body. Measurements also were made of anteroposterior parasagittal vertebral depth with both medial and lateral inclination of 10 degrees, with respect to the parasagittal plane of the vertebral body.
Results:
The ideal maximum screw length and trajectory was found to be AP medial parasagittal depth of inferior surface of the C2 body [Right: 13.7 +/- 1.4 mm (11.0-17.9), Left: 13.6 +/- 1.5 mm (10.7-17.8)].
Conclusions:
We report the measurements of the vertebral body of the C2. We think these measurements provide guidelines for operating on the anterior C2 spine, and enhance the confidence interval for the surgeon (Tab. 3, Fig. 1, Ref. 24).
