A quantitative analysis of the structure of human sternum.

Arbabi A - J Med Phys (2009)

Bottom Line: The percentage bone volume is 13.8 and the surface to volume ratio is 190 cm.Data on the structural variations within the whole sternum are presented.They show a percentage difference in bone volume between the manubrium and the body of sternum of about 36%.

ABSTRACT
An extensive study of the human sternum has been carried out to obtain estimates of the omnidirectional path-length distributions and structural parameters for trabeculation and marrow spaces. Data for sternum samples have been collected, using an object plane scanning microscope. These data have been used to produce the omnidirectional path-length distributions and values of structural parameters for the whole sternum. For a typical adult man the mean trabecular and marrow space path lengths are 224 and 1364 mum, respectively. The percentage bone volume is 13.8 and the surface to volume ratio is 190 cm. Data on the structural variations within the whole sternum are presented. They show a percentage difference in bone volume between the manubrium and the body of sternum of about 36%.

Figure 0006: Schematic division of the sternum into inner and outer zone

Mentions: The results indicate that trabecular thicknesses are larger and marrow spaces are smaller in the manubrium than the body of the sternum, consequently giving higher percentage bone volume to the manubrium (∼56%), which, apart from its larger overall width and thickness, gives it more strength than the body. To analyze the structural variations of the sternum in a direction parallel to the horizontal (×) axis, the sternum was divided into two zones, outer and inner, as demonstrated in Figure 6.
