Abstract

Cross-sectional study. To compare 2 techniques of transarticular screw placement in the subaxial cervical spine. Transarticular screws have been used as an alternative method to achieve posterior cervical spine stability. According to current studies there are several techniques for the placement of transarticular screws in the subaxial cervical spine; however, there is no study that has compared these techniques. The techniques of transarticular screw placement by Takayasu (group A) and Dalcanto (group B) were used in 8 cervical specimens. The position, number of facet fractures, involvement of the vertebral artery, encroachment of the anterior branches of cervical nerve roots, and instances that failed to go through the facets were observed and analyzed. Sixty-four screws were implanted, 32 for group A and the same for group B. Although no facet fractures were seen in group A, there were 10 in group B (χ=9.6, P<0.01). Eight screws involved the vertebral artery in group A and 0 in group B (χ=22.3, P<0.001). Eleven anterior branches of lower cervical nerve roots were encroached in group A and 2 in group B (χ=22.0, P<0.001). No screws failed to go through the facets in group B whereas 2 screws failed in group A, resulting in no ...Continue Reading
