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 0005: Omnidirectional path-length distributions, human adults' sternum

Mentions: The general trend is for the mean trabecular path lengths to decrease as the mean marrow space path lengths increase from the jugular notch toward the xiphi-sternal junction. Consequently, the percentage bone volume decreases and the surface-to-volume ratio increases over the length of the sternum. In order to reveal the structural differences between the manubrium and the body of the sternum the structural parameters for both parts are given in Table 3, and their omnidirectional path-length distributions for marrow spaces and trabeculae are shown in Figure 5.
