Cortical bone blood flow of the intercalary segment of bone. Values for each time point were the average reading from the three different laser doppler flowmetry measurement locations. The values at each time point were all normalized by dividing by the average value at baseline. The error bars indicate one standard error of the mean. No statistically significant differences between Contusion and No-Contusion groups were found (p > 0.05). All procedures at each time compared to baseline showed statistical differences (p < 0.01), except for 11 weeks in the No-Contusion group (#, p = 0.49).
