Figure 6From: Biomechanical effects of polyaxial pedicle screw fixation on the lumbosacral segments with an anterior interbody cage supportComparison of cage contact ratio among constructs with various lordotic contours during compression. Effects of monoaxial and polyaxial pedicle screws are illustrated respectively. * significant difference from data of 0° group (p < 0.05). § significant difference from data of 21° group (p < 0.05).Back to article page
