"Most encouraging from these results is that anterior reconstruction alone using the No Profile™ STALIF C™ three screw device can reduce segmental motion to levels similar to that produced using conventional interbody arthrodesis augmented with anterior cervical plate fixation."1

Non-Destructive Range of Motion Testing:
1. Axial Rotation (± Y-axis)
Axial rotation testing demonstrated, as expected, the intact cervical spine as producing significantly more motion at the operative C4-C5 level compared to all other treatments ( p <0.05). The stand alone allograft bone dowel, although having an excellent fit within the operative level, exhibited significantly more motion than the STALIF C™. No other differences were noted between any other reconstructions (p>0.05) (One Way ANOVA: F=9.06, p=0.000).
Axial Rotation Range of Motion (Degrees):
* Indicates difference from all other treatments,
** from STALIF C™ three screw groups at p<0.05. Error bars represent one standard deviation and significance is indicated at p<0.05.
