Abstract: The purpose of this study was to determine the incidence of humerus septal apertures among the Greek population. The presence of supratrochlear foramen was studied using 656 human humeri (304 male and 352 female). Out of the 656 pairs of humeri, we detected two female pairs of humerus bones with bilateral, equal size and shape, septal apertures. This is a rare finding. The overall frequency of septal apertures among the Greek population appears to be as low as 0.304% in the general population, with a marked absence among males and a 0.568% incidence for females.
