Cribra orbitalia in micro-CT

The question answered by this project was how the morphological structure of a diploë changes according to the different degrees of CO expression. The basic technique was micro-CT scanning, which is one of the most accurate methods for analyzing the morphometry of anatomical objects, especially those of small dimensions.
A total of eleven superior surface eye orbits of children’s skeletons were used. On two of them, no changes typical for CO were observed. Four orbits had porosities less than 1 cm2 in area. On five superior surfaces of the orbits, porosities occupying an area greater than 1 cm2 were observed. The samples were scanned by a Bruker SkyScan 1172, and then the volumetric projections obtained in this way were reconstructed. In the next step, six parameters characterizing the structure of the spongy bone were measured, i.e., the number of trabeculae (Tb.N), the distance between the trabeculae (Tb.Sp), the thickness of the trabecular bone (Tb.Th), bone volume (BV/TV), bone surface area to volume ratio (BS/BV), and bone density (BS/TV).
