A histological examination of spinal reconstruction using a frozen bone autograft
Fig 5
The amount of newly formed bone in each of the 8 sub-sections of the cage is graphed with mean±standard deviation for each group.
The proportion of reaction regions is significantly higher in the ends of the cage compared to its center region, as well as on the dorsal region compared to the ventral region in the both 8-week groups. In contrast, the C-16w group has a higher proportion of reaction regions in the center of the cage, while the F-16w group shows little increase in this section, while the proportion of mature regions was similar between the two groups.
