Figure 7. Annulus injury altered torsional biomechanical properties relative to intact and FibGen repair restored some of these changes.

Figure 7

(A) The ± 2° torque range (ratio to intact) of the Injured group was higher than the FibGen group. (B) The torsional stiffness of the Injured group had a trend of increase compared to the FibGen group (p < 0.1). (C) Representative ± 2° torque rotation curves of an Injured sample in intact (black) and injured (red) condition shows median effect of injury on torque range. (D) The ± 4° torque range ratio of the Injured group had a trend of increase compared to the FibGen group (p < 0.1). (E) The ± 4° torsional stiffness ratio did not differ between groups. (F) Representative ± 4° torque rotation curves of a FibGen sample in intact (black) and repaired (green) condition shows median effect of injury on torque range. Lines are median, error bars are interquartile range, bars indicate significant difference (p < 0.05) and dashed line bars indicate trends (p < 0.10).
